Abstract

Objective: Hypertension, a prevalent global health challenge, often suffers from inadequate dietary management among patients. Current dietary management apps still have a lot of room for improvement when providing service to hypertension patients. This study proposes developing and evaluating a novel mobile phone-based diet management system specifically designed for hypertensive patients. This system aims to improve the pertinence for hypertensive users and improve app usability through Enhanced UI/UX, voice-based and image-based input modalities.

Methods: This research used a within-subjects study design and fly-on-the-wall observation to obtain user feedback on image-based and voice-based input.

Conclusion: The experimental results are consistent with the previous hypothesis that voice-based input and image-based input can improve app usability to some extent. However, the UI design of the app still needs some optimization in order for the user to use the app correctly without additional guidance.
