Neck Flexion Angle and User Experience Compared on iPhone X and Samsung S8+

There have been a lot of research and explanation on Smartphone screen size and user experience of numerous Smartphones. This study considers the difference between neck flexion angle and its effects on human ergonomics while using two Smartphones with different screen sizes and display features (iPhone X and Samsung S8+). This study also collects user experience data through a questionnaire to generate the most ergonomic model among the Apple Inc.’s iPhone X and Samsung S8+. 8 participants were considered for this study. A digital goniometer was used to analyze participant’s neck flexion angle while using both the Smartphones (iPhone X and Samsung S8+). A paired t-test of means was performed. Neck flexion angle was highly flexed for the participants while using iPhone X than compared to the neck flexion angle while using Samsung S8+. Participants felt more comfortable using both Smartphones. However, ‘True-tone’ technology in iPhone X eased the stress level of eyes according to the users. This study suggests a large screen smartphone with ‘True-tone’ or similar technology, which can be an iPhone X but with a larger screen size.
