  Nye og bedre Augmented Reality (AR) og Virtual Reality (VR) applikasjoner utvikles helle tiden og brukes mer og mer i handel. Utvikling i AR and VR i løpet av de siste årene satt i gang mange innovasjoner i måten handelen foregår, innovasjoner i markedsføring, og innovasjon i design og utvikling av produkter og tjenester. Likevel, vet vi lite om muligheter som AR og VR skaper for innovasjon og om erfaringene fra de som allerede bruker dem. Denne artikkelen beskriver hvordan AR og VR kunne med fordel brukes for flere typer av innovasjon og hjelpe forretningsvirksomhet til å vokse. Artikkelen gir en oversikt over eksisterende innovasjonspraksis i handel og kan hjelpe norske virksomheter i deres strategiske planlegging. Vår analyse viser at AR/VR innovasjon kan bidra til bygning av merkevære, restrukturering av prosesser i organisasjon, involvering av kunder i verdiskapning, kan gi ekstra after-sale tjenester ved å gi produkt relatert informasjon i kontekst, kan støte omnimarket strategier og påvirke kjøp ved virtuell try-on opplevelser.

  Purpose: While (customer) engagement has been proposed as a volitional concept, our structuration theory/S-D logic-informed analyses of actors’ (e.g. employees’) engagement in service innovation reveal engagement as a boundedly volitional theoretical entity. Engagement’s boundedly volitional nature arises from actors’ structural and agency-based characteristics and constraints that are addressed and further developed in a conceptual model of actor (i.e. customer, firm, employee) engagement with service innovation. Design/methodology/approach: Based on the observed gap, we propose an integrative S-D logic/structuration theoretical model that outlines three particular service innovation actors’ (i.e. customers’, the firm’s, and employees’) engagement, which comprises institution-driven (i.e. fixed) and agency-driven (i.e. variable) engagement facets. In addition, we integrate the key expected characteristics of positively (vs. negatively) valenced service innovation engagement for each of these actor groups in our analyses. Findings: We develop a 12-cell matrix (conceptual model) that outlines particular service innovation actors’ institution-driven and agency-driven engagement facets, and outline their expected impact on actors’ ensuing positively and negatively valenced engagement. Research limitations/implications: We discuss key theoretical implications arising from our analyses. Originality/value: Outlining service innovation actors’ structure- and agency-driven engagement facets, our model can be used to explain or predict customers’, the firm’s, or employees’ service innovation engagement-based activities.

  The paper describes our ongoing work on a new prototyping method for service design, Virtual Bodystorming. Virtual Bodystorming utilizes Virtual Reality (VR) and enables the user to role-play the service scenario in a fully immersive and collaborative VR environment. In this environment, various service-related areas and objects can be recreated with 3D graphics, while distant service users, providers, designers, and facilitators can communicate and collaborate. Virtual Bodystorming aims to minimize the gap between the actual service environment and its prototype by contributing to the development of fully immersive and highly-engaging service simulations. To illustrate the practical implementation of Virtual Bodystorming, we describe its main characteristics and present a first prototype version of the method. The method was evaluated by three experienced service designers, who highlighted the strengths of Virtual Bodystorming for service prototyping, regarding immersion and engagement, while emphasizing the service designer’s significant role in directing the user interactions of the VR scene. The method was considered to be suitable for prototyping services that include human interaction and/or spatial aspects.

  Companies employ innovation platforms, like crowdsourcing and open innovation platforms, to gather ideas and engage their customers in service innovation processes. Although this might be a technically easy way for customer involvement in service innovation, companies need to understand the drivers and challenges of customer participation through the innovation platforms. The chapter explores a bank’s crowdsourcing platform that gathers customers’ ideas on financial services and the future of banking. A case study is described examining two types of factors that influence customers’ intention to participate in the crowdsourcing platform: (1) motivational factors, including perceived enjoyment, recognition and social presence, and (2) factors of perceived trustworthiness, including ability, integrity and benevolence. The study revealed associations between trustworthiness and motivational factors on one side and customers’ behavioral intention to share ideas with the bank on the other. Association with trustworthiness was stronger. Trustworthiness thus emerges as a key factor for establishing customer-company communication in innovation platforms.

  This paper presents our ongoing research into trust and the risks related to online grocery shopping. More specifically, we investigate how to increase customer trust when buying perishable products online. Online grocery shopping is an increasing trend in many countries, and several studies on trust have been conducted in the context of online grocery shopping. However, knowledge of how to improve trust and reduce risks is rather limited in this context. Through design, prototyping and user studies, we explore if and how a variety of user feedback mechanics such as ratings, comments and presence help build trust. Several concepts and prototypes were evaluated through group interviews and usability testing. Based on our results, we proposed trust-related design guidelines for online grocery shopping applications. Our results might be useful to both researchers investigating trust in the context of online shopping and to the practitioners designing applications and services in this area.

  Design for motivation can be defined as a “design practice focused on the activation of human motives, with short or long-term effects, to perform an action” in a context. The paper proposes and develops a design tool called DEMO (DEsign for MOtivation) that aims to address motivation in innovation communities. The DEMO tool is theoretically grounded in motivation theories and based on existing game-like approaches for the development of motivational concepts. The tool incorporates gamification elements, design elements and targets to support multidisciplinary teams in designing for motivation. One application area of the tool is in innovation communities where the design to support user participation and contribution is a complex task, while there is limited understanding how to practically apply motivation. An expert usability evaluation reflected a positive overall experience with the tool. The contribution of this paper lies in its description of the tool and its report on the usability evaluation. Future research in the field should focus on the application of the design tool with various methods in diverse cases.

  Open innovation platforms (OIPs) are applied to service businesses and aim to increase service innovation, by engaging users and encouraging them to submit ideas, share content, and invite others to participate. The employment of OIPs raises several ethical issues, such as fairness, ownership, and privacy. One approach for addressing these issues is to raise the visibility of ethics on the platform. Following a systematic approach, this paper explores the topic of the visibility of ethics in OIPs, by reviewing related ethical issues and evaluating the application of ethics by OIPs in practice. We conclude with reflections on design and suggestions for practitioners. The visibility of ethics is seen as a proactive design state, and we argue that it can both improve service innovation through OIPs, and improve the fairness of relationships between customers and companies.

  Online social platforms, such as blogs, discussion forums and social networking sites, are increasingly explored as venues for user-centred evaluations; in particular, for design feedback from users. We present a multi-case study providing needed knowledge on such evaluations. Our findings are based on analyses of the design feedback and post-factum data collections with development team representatives and users. The development team representatives reported as key benefits that the evaluations provided insight into users’ needs and competencies, input into ongoing design discussions and support for idea generation in the development team, but found the lack of direct contact and control with the users to be an important limitation. The users appreciated the opportunity to contribute to the design process, but the majority reported not to build on each other's contributions. Involving a relatively large number of users was found to be beneficial for generating constructive design suggestions. Practical implications and future research challenges are suggested.

  It is challenging for service companies to obtain a detailed overview of their customers’ end-to-end service delivery processes. This paper extends previous work on a structured approach for modelling customer journeys to encompass complex, technology-driven service systems. We report on how the approach can support documentation and analysis of service delivery from a customer perspective, and present a case study of a consumer-to-consumer (C2C) service in an eMarket company. The case study involved mapping of the service process as intended by the service provider (planned journey), as well as customer journeys as experienced by users (actual journey). Our results reveal that the approach supported the eMarket company in obtaining a detailed overview of the service process, and in understanding the customers’ experiences. Deviations between planned and actual journeys uncovered user issues and gaps in the service delivery, pointing to parts of the journey that were prone for improvements and redesign.

  The amount of online video content available to us is rapidly increasing. Understanding how people are seeking and consuming this content is a prerequisite for providing good services. This paper investigates if and how log data can be used to identify information seeking behaviour in the context of online TV. A study was conducted where 27 participants performed given tasks on two Norwegian online TV sites. The participants were between 20 and 25 years old and all of them were moderate or heavy users of online TV. Tasks that require both scanning and searching of information were given. Four main types of behaviour were identified in the qualitative data: goal-directed search, goal-directed meta-data search followed by consumption, goal-directed search of meta-data and video, and explorative behaviour. Detailed log event files were compared to self-reported data describing user's activities (feedback collected at the end of each task and interviews) and screen captures. Our results indicate that the following four variables in the log files: number of (short navigation sequence, short video watching sequence) pairs, frequency of video search actions, percentage of time spent on sequences of navigate actions, and percentage of time spent on watching videos can be used to characterise the four types of behaviour. This work extends previous research on usage of log files in describing user's behaviour by providing simple way of characterizing behaviour of online TV users. In particular, the results might be useful in supporting the personalisation of online TV services.

  Air Traffic Management is responsible for guiding airplanes as efficiently and safely as possible at and between airports. A team of air traffic controllers is required to make good decisions at all times, even under high stress. The complexity of their tasks requires frequent and high-quality training to ensure constant high performance of the team. In this paper, we present work in progress on a novel training tool based on the Optimization-based Virtual Instructor. The tool we propose combines mathematical optimization with visualization, and is expected to improve the training quality while reducing the training cost. We discuss the new Virtual Instructor concept and introduce the necessary state-of-the-art advances needed for both visualization and mathematical optimization to make it work. Two early-stage visualization prototypes are presented. The paper concludes with a possible way forward in the development of the Virtual Instructor.

  Business process management aims to align the business processes of an organisation with customers’ needs. Such alignment is of particular importance for services and requires a good understanding of the interactions among the actors involved. Although several process modelling languages and a service design technique called ‘service blueprint’ provide good support for modelling of service delivery processes, the actual execution of service and networked interactions among actors seem to have not been sufficiently considered. To overcome these limitations, we developed the Service Journey Modelling Language. Each version of the language has been evaluated, and the results were used as input for the next version. Results from our case studies show that our language might supplement the management of business processes for services by aligning business processes with customer perspectives and by supporting depiction of the actual service journeys with networked interactions of involved actors using appropriate visual representations.

  Air Traffic Management is the complex task of safely managing the flow of aircrafts. This task needs to be solved efficiently to avoid hindering the growth of the aviation sector. Optimization-based decision support tools could assist but, this being a safety-critical and conservative domain, a high level of trust needs to be in place. The amount of trust depends on the level of automation and familiarity with the tools. We argue that this needed trust could best be built if optimization based tools are used in the training of air traffic controllers. We discuss how this training can help air traffic controllers and the model of optimization.

  Open Service Innovation (OSI) platforms invite customers and other users to co-create innovative ideas and generate experiences that will potentially create value. In this paper, we propose a framework for designing experiences for service users of OSI platforms. The framework utilise the following four types of experiences described by Polaine et al.’s (2013): user experience, customer experience, human experience and service provider experience by the properties relevant within the OSI context. Our framework might provide useful insights to OSI platform designers and help them to effectively involve users in the innovation process.

  This paper presents the results from a qualitative study that examines managers' perspectives on open innovation platform (OIP) selection, focusing on their main criteria, requirements and needs. Six managers of a large company were interviewed about their experiences. This paper shows that platform selection is a combination of factors, and the creation of a company culture around OIP is very important in users' minds. Based on the results, we propose a list of selection criteria and dimensions for OIP classification. Our findings showed that criteria include ease of access, ease of innovation process, ease of integration and compatibility, as well as cost, fast, secure, differentiation for various user groups and the method of evaluating ideas. These results can be useful to support managers in their decision-making processes when selecting OIPs, in addition to helping platform designers and researchers.

  This paper proposes a post-simulation assessment tool that aims to improve the training of air traffic controllers (ATCOs) by visualizing their performance. The tool helps the controllers to identify bottlenecks in flight traffic and find alternative solutions that might improve traffic throughput. The usefulness of the tool was evaluated in a study involving benchmark tests and interviews with five experienced ATCOs. The results from the study indicate that the tool can help ATCO students to (1) identify irregularities in their work, (2) find possible underlying causes of these irregularities, and (3) find alternative solutions preventing these irregularities. Visual feedback consisting of workflow graphs and radar replays might generate valuable insights that enable self and peer assessment during ATCO training. Our results might be interesting both for the practitioners working with ATCO training and for researcher investigating the effects of visualization in education.

  The use of Living Labs is gaining importance as an approach to involve users in innovation and development, serving to make users active participants in the development of the networked society. However, Living Labs are currently not taking full advantage of online applications to support user involvement, even though such applications are gaining impact in other fields of innovation. The purpose of this chapter is to: (i) present a framework to classify and relate online applications for user involvement to the Living Lab context and (ii) present a set of guidelines for the usage of such applications within Living Labs. The framework and the guidelines are the results of a collaborative process involving seven Living Lab researchers from four Nordic Living Labs and are meant to guide Living Lab administrators on whether or how to use online applications for user involvement. The framework and the guidelines might also be useful for the designers of online applications.

  The rapidly increasing importance of multimedia services delivered over telecommunication networks has heightened the need for technologies that adapt efficiently to users’ needs. It is of particular interest to understand users of such services. This paper proposes a unified approach to modelling users’ behaviour and experiences in the context of new multimedia services. Static information on users’ behaviour is integrated with users’ real-time feedback about their experiences. A unified user profile is used for implementation of a media-aware, user-dependent, self-adaptive network resource manager. Our first experience shows that such a unified approach might be beneficial for network and service providers. The tool for gathering real-time user experience, we propose, might also be useful in other contexts, such as personalised content recommender systems.

  Business process management aims to align the business processes of an organisation with customers' needs. Doing this is of particular importance for services and requires a good understanding of interactions among the stakeholders involved in service provision and consumption. Several business modelling languages have been proposed, such as Business Process Modelling Notation (BPMN), Business Process Executable Language (BPEL) and Web Services Choreography Description Language (WS-CDL). Although these languages provide good support for process modelling, their consideration of the customer’s point of view seems to be insufficient. On the other hand, visualisations of customer journeys for the purpose of conceptualisation of new services have been successfully used in the area of service design. Our hypothesis is that a visual language presenting the customer journey through a service might be useful for aligning business processes of service providers with customers' needs and, in turn, contribute to the delivery of better services. We propose Service Journey Modelling Language (SJML) and report our first experience with it.

  Virtual museums enable Internet users to explore museum collections online. The question is how to enhance the viewer's experience and learning in such environments. In the Sarajevo Survival Tools virtual museum we introduced a new concept of interactive digital storytelling that will enable the visitors to explore the virtual exhibits - objects from the siege of Sarajevo - guided by a digital story. This way the virtual museum visitors will learn about the context of the displayed objects and be motivated to explore all of them. In this paper we present the virtual environment we developed and our experience with it. The results from three empirical studies we conducted, indicate the positive influence of digital storytelling and sound effects on visitors' perceptual response, resulting in increased motivation and enjoyment, and more effective information conveyance.

  Previous research has shown benefits of user feedback early in the innovation process. An effective way of gathering such feedback might thus accelerate innovation. A case is presented on the use of social media functionality to capture user feedback in early phase service innovation. Through the method of social design feedback, where all participants can see and comment on each other’s feedback in an online environment, 207 users provided their feedback on three innovative service concepts. About one third of the comments contained suggestions for redesign. The case shows that social design feedback is a viable approach to capturing users’ feedback in early phase service innovation, long before resources are spent on implementation. Future work is needed on understanding participants' motivation for discussing feedback given by others. Guidelines or functionality stimulating such discussions might help improve the level of detail in the feedback.

  The use of Living Labs is gaining importance as an approach to involve users in innovation and development, serving to make users active participants in the development of e-Society. However, Living Labs are currently not taking full advantage of online applications to support user involvement, even though such applications are gaining impact in other innovation fields. To support the uptake and future development of online applications for user involvement in Living Labs we propose a framework that classify and relate such applications to the Living Lab context. The framework serves to classify types of online applications for user involvement, and the high level Living Lab activities which these may support. The application types are classified according to different phases of the innovation and development process. The high level activities include short term user campaigns and maintaining long term user relationships. Three issues related to the framework are discussed; that is, (a) process phase as determinant of the relevance of online applications for user involvement, (b) integration of online and traditional approaches to user involvement, and (c) trade-offs when choosing online applications, are discussed. The framework is the result of a collaborative process involving seven Living Lab researchers from four Nordic Living Labs, and is meant to guide Living Lab representatives that are considering whether or how to utilize online applications for user involvement.

  A ”Single European Sky” is the vision of the future for European Air Traffic Management (ATM) aiming to increase capacity whilst significantly reducing costs for managing the European air traffic. The work undertaken in the control centres by the controllers and their colleagues are critical for safe and productive operations. The roles and responsibilities of the controllers and control centres will change significantly as the vision of a single European sky is realised. In order to facilitate this transition, it is vital that the air control centres and the air traffic management system have essential and appropriate tools to improve and develop processes on both an individual and an organisational level to ensure safe and productive air traffic. This paper addresses the need for introducing and implementing principles of continuous improvement of human and organisational processes in air traffic control centres. More specifically, the paper focuses on the team decisions in the ATCC (Air Traffic Control Center) and their effect on productivity.

  Online collaborative writing applications might motivate children to write together and thus stimulate their learning and crativity. Although a lot of research has been done on collaborative tools in the professional context, little has been known on collaborative writing for children. This paper investigates which user experience factors stimulate children to write together. An application for collabrative writing has been evaluated with 35 school children. Based on the results of this evaluation we give a list of recommendation for design of such applications.

  The popularity of multimedia streaming services is rapidly increasing. In-depth knowledge of the users’ behaviour is one of the cornerstones of delivering optimal Quality of Experience in such services. In this paper, we present the results of three studies that investigate the patterns of users’ behaviour in Spain, Sweden, and Norway. Based on an analysis of the network traffic data and questionnaires from more than 270000 individual users and households, we identified user accesses over time as well as the users’ habits, preferences, and motivations. Our results show the stability of users’ behaviour across the countries and over time and the differences among the users and access types. The insights obtained in this study might provide valuable inputs for the design of future network management systems and multimedia streaming services.

  Weighted dependency trees (WDTs) are used in a multitude of approaches to system analysis, such as fault tree analysis or event tree analysis. In fact, any acyclic graph can be transformed to a WDT. Important decisions are often based on WDT analysis. Common for all WDT-based approaches is the inherent uncertainty due to lack or inaccuracy of the input data. In order to indicate credibility of such WDT analysis, uncertainty handling is essential. There is however, to our knowledge, no comprehensive evaluation of the uncertainty handling approaches in the context of the WDTs. This chapter aims to rectify this. We concentrate on approaches applicable for epistemic uncertainty related to empirical input. The existing and the potentially useful approaches are identified through a systematic literature review. The approaches are then outlined and evaluated at a high-level, before a restricted set undergoes a more detailed evaluation based on a set of pre-defined evaluation criteria. We argue that the epistemic uncertainty is better suited for possibilistic uncertainty representations than the probabilistic ones. The results indicate that precision, expressiveness, predictive accuracy, scalability on real-life systems, and comprehensibility are among the properties which differentiate the approaches. The selection of a preferred approach should depend on the degree of need for certain properties relative to others, given the context. The right trade off is particularly important when the input is based on both expert judgments and measurements. The chapter may serve as a roadmap for examining the uncertainty handling approaches, or as a resource for identifying the adequate one.

  The skills of software developers are important to the success of software projects. Also, when studying the general effect of a tool or method, it is important to control for individual differences in skill. However, the way skill is assessed is often ad hoc, or based on unvalidated methods. According to established test theory, validated tests of skill should infer skill levels from well-defined performance measures on multiple, small, representative tasks. In this respect, we show how time and quality, which are often analyzed separately, can be combined as task performance and subsequently be aggregated as an approximation of skill. Our results show significant positive correlations between our proposed measures of skill and other variables, such as seniority, lines of code written, and self-evaluated expertise. The method for combining time and quality is a promising first step to measuring programming skill in both industry and research settings.

  The purpose of this study is to better understand the digital divide by identifying the variety of ways in which people in Europe use the Internet. First, by using cluster analysis on survey data (N=12,666/age: 16–74 years) from Eurostat on Internet usage in Norway, Sweden, Austria, the UK, and Spain, we identified five user types: Non-Users (42%), Sporadic Users (18%), Instrumental Users (18%), Entertainment Users (10%), and Advanced Users (12%). These user types differ in their distributions over country, age, access, household members, and gender. An alarming finding is that 60% of the population was found to be either Non-Users or Sporadic Users, which reflects a large digital divide in Europe. Second, we conducted a logistic regression to identify the predictors for different user types. We found on a cross-national level that age and Internet access are the most salient predictors, whereas gender and household seems to be less relevant. However, the amount of variance explained differs between countries. We also suggested a future increase in the digital divide between the identified user types—a user type divide. The user typology and the identified predictors might help researchers, practitioners, and decision makers to better understand Internet users and the multi-complex variations among individuals and countries. This knowledge will also serve as a means to understand the digital divide by providing a more nuanced perspective on Europeans' unequal usage of the Internet and participation in an increasingly digital society.

  This report summarizes the motivation and the goals of the "CyberWiseKids" project proposal. The proposal was designed by SINTEF in 2015 and revised in 2016, with the aim of developing a research and innovation project which would involve several industrial and academic partners from Norway and Europe. The underlying idea was motivated by the need for enabling children and young people to make the right balance between online opportunities and online risks. A significant innovation potential was envisioned and elaborated within the proposal. Although far less detailed than the original project proposal and excluding several major aspects (e.g. innovation, organization, project plans research questions, and state of the art) that were part of the original proposal, this report quotes and reproduces the parts (of the original proposal) regarding motivation, challenges, and the objectives. The purpose of this report is to enlighten the persistent challenges that young people are facing while being online, as well as to indicate the still-existing needs and opportunities for addressing such challenges through innovation and research.

  Denne rapporten presenterer et kunnskapsgrunnlag for prosjektet Førstehjelpsopplæring i grunnskolen. Rapporten baserer seg på analyse av 25 forskningsartikler, og trekker ut den viktigste kunnskapen som er relevant for utviklingen av prosjektet. Analysen konkluderer med at alderstilpasset skolebasert opplæring og trening i førstehjelp kan gis til svært unge barn, og at slik opplæring kan gi gode resultater når det gjelder å øke kunnskaper om skadereduksjon, øke ferdighetene i grunnleggende livredning og øke selvitilitt til at de kan hjelpe. Opplæringsopplegget bør baseres på praktiske øvelse og faktakunnskaper, og bør være tilpasset aldersgruppen. eLæring og annen teknologibasert opplæring kan med fordel supplere praktiske øvelser. Bruk av digitale verktøy for trening, instruksjon og spill kan redusere tid og ressursbruk. Pilotprosjektet bør evaluere resultater av undervisningsopplegget rett etter opplæringen/ ved avsluttet opplæring, og en god stund etter gjennomført opplæring (noen uker/måneder). Evalueringen bør gi kunnskap om elevenes kunnskap, ferdigheter og holdninger knyttet til læringsmålene, og fange opp dimensjonene kjennskap til, kunnskap om, ferdigheter i og mestring av.

  Netthandel: I 2017 handlet 11,6 prosent av nordmenn dagligvarer på nett, det er en fordobling sammenlignet med året før. Men når det gjelder innkjøp av enkelte vareslag sitter det langt inne å bestille på nettet. Vi går helst selv til butikken. Det er spesielt to typer produkter kundene kvier seg for å handle: Det første er dyre ting som elektronikk, det andre er ferskvarer som frukt og grønnsaker. Kundene vil helst selv se om bananen er moden nok, eller kjenne etter om avokadoen er passe fast, sier seniorforsker i SINTEF Digital Amela Karahasanović. Hun har ledet prosjektet «Design for trust – online grocery shopping». I et samarbeid med NorgesGruppen har SINTEF undersøkt hva som må til for å øke kundenes tillit til handel av ferskvarer på nettet.

  Online grocery shopping is an increasing trend. In 2017, 11.6% of Norwegians bought their groceries online, which is twice as much as in 2016, and even more people are thinking about doing so. An online survey based on responses from 60 countries showed that a quarter of the respondents reported buying groceries online, while more than half (55%) were considering doing so in the future. The main problem related to the online purchase of perishable groceries, such as fruits and vegetables, is the perceived risk of receiving products that do not meet the customers’ expectations. Through a series of prototypes and evaluation studies conducted in collaboration with NorgesGruppen, we investigated how to increase the trust of customers who buy perishable products online.

  Presntation of the paper published at the Conference. Abstract. This paper presents our ongoing research into trust and the risks related to online grocery shopping. More specifically, we investigate how to increase customer trust when buying perishable products online. Online grocery shopping is an increasing trend in many countries, and several studies on trust have been conducted in the context of online grocery shopping. However, knowledge of how to improve trust and reduce risks is rather limited in this context. Through design, prototyping and user studies, we explore if and how a variety of user feedback mechanics such as ratings, comments and presence help build trust. Several concepts and prototypes were evaluated through group interviews and usability testing. Based on our results, we proposed trust-related design guidelines for online grocery shopping applications. Our results might be useful to both researchers investigating trust in the context of online shopping and to the practitioners designing applications and services in this area.
