Mobile phones have become an integral part of our lives, and this is especially true for mobile users in Saudi Arabia. Therefore, people frequently adopt harmful postures when using smartphones for extended periods of time, bending their neck and upper torso forward, which leads to disorders like cervical myalgia. To prevent these disorders, this study aims to design, develop, and test an AI-based smart stand for mobile phones that automatically adjusts height and distance according to user head posture, reducing musculoskeletal discomfort and improving ergonomics. Ten participants were randomly assigned to two different conditions: smart stand use and traditional stand, utilizing basic randomization to mitigate possible systematic bias arising from the sequence of experiments. All individuals experienced both situations on different days. Body discomfort rate, usability, and user experience were collected for each participant after 10 min of chatting, 10 min of watching video, and 10 min of web surfing on a smartphone. The results showed that participants who use Smart Stand led to enhanced user performance and reduced neck and shoulder discomfort as compared to traditional stands. The SUS indicates unfavorable evaluations for the traditional stand regarding both perceived utility and perceived ease of use. The smart stand was considered highly beneficial and user-friendly. The smart stand automatically adjusts the optimal height of the stand 's eye center and the distance between the user and the device, ensuring maximum comfort and reducing physical strain, particularly on the neck. The smartphone stand greatly enhanced the quality of life.
