  Hijab is an obligatory clothing for Muslim women that has now developed into a fashion trend with various types such as Pashmina, Square, and Instant hijab. The growth of hijab business, primarily through e-commerce, presents a challenge for consumers to try and choose hijab online. This research aims to design an application that overcomes this problem by utilising Augmented Reality (AR) technology to visualise the appearance of consumers when wearing hijab, as well as the application of deep learning with MobileNetV1 architecture to classify the shape of consumers’ faces and provide appropriate hijab recommendations. The implementation results show that the face shape-based hijab recommendation system can perform classification well, where 76% of 25 respondents expressed satisfaction with the hijab recommendation results. The AR-based virtual try-on feature also provides a satisfying hijab trying-on experience, with 76% of respondents feeling satisfied. Overall, 84% of respondents stated that the app helped them shop for hijab online. This finding shows the app’s potential to enhance the virtual hijab shopping experience.

  Medical education requires a deep understanding of complex physiological systems, particularly cardiac anatomy. Conventional media often lack the interactive 3D visualization necessary for spatial comprehension. While Augmented Reality (AR) offers immersive solutions, existing applications heavily rely on physical markers, limiting flexibility. This study presents HeartAR, a markerless AR application utilizing ground plane detection to facilitate interactive, self-directed exploration of 3D cardiac models. Developed through a Human-Centered Design framework, the system integrates multi-axis rotation, anatomical labeling, and dynamic heartbeat simulations.We evaluated the system’s usability with medical students using task-based observations and the System Usability Scale (SUS).The evaluation yielded an SUS score of 79.75, indicating a high level of usability and user acceptability. The core contribution of this work lies in the practical implementation and usability validation of markerless spatial tracking for specific anatomical modules, providing foundation for accessible, outside-the-classroom medical training tools.
