Should it be all wrapped up? Impact of functional area and weight on user comfort of wearable devices based on phase change materials
研究通过设计基于相变材料的冷敷贴，测试了不同功能区域面积和重量对用户冷感、湿感、织物质感、疲劳感和整体舒适度的影响，发现中等功能区域可能是更优的设计选择。
The comfort of wearable devices is determined by a variety of design factors. In this study, we developed a cold compress using a phase change material design and explored the effects of functional area and weight on the user experience in a wearable device. A total of 9 groups of 3 (high, medium, and low functional area) × 3 (heavy, moderate, and light weight) were evaluated for coldness sensation, wetness, fabrics texture, fatigue, and wearing comfort. Our study found that the functional area had a significant impact on the wearing experience of the wearable device. The high functional area performed best in terms of coldness and wetness, but poorly in terms of fatigue. Further research demonstrates that a medium functional area may be a better way to design wearables. In addition, it can also provide new design ideas and references for the development of wearable devices through perceptual errors.
