Comfort of smartwatch wearing: A comparative study of different hand types

<p>This study aims to explore the relationship between wrist size and the comfort and fit of smartwatch wearability. Measurements of hand dimensions, including wrist width, palm length, finger length, and finger width, were taken from 41 participants. Based on the analysis results, participants were grouped by wrist width, and individuals from different groups were asked to subjectively rate the comfort, strap fit, and ease of operation of the smartwatch. The results revealed that wrist width significantly impacts wearing comfort, while other hand features (such as finger width) play a crucial role in the operational experience. Users with wider wrists rated strap fit and wearing pressure more favorably, whereas those with narrower wrists demonstrated superior touchscreen operation performance. Additionally, the significant effects of design factors such as strap material, dial size, and smartwatch weight on wearing experience were also validated. These findings provide valuable insights for smartwatch design, highlighting the necessity of considering variations in hand dimensions to enhance the overall user experience.</p>
