Touch technology-based smart homes have become increasingly prevalent, as they can help people with independent daily life, especially for the elderly. The aim of this study was to investigate the effects of button features (i.e., button size, graphics/text ratio, and icon style) in smart home interfaces on user performance across two age groups. Participants in the young group ( = 15) and senior group ( = 15) completed a clicking task. Button size ranged from 10 mm to 25 mm with 5 mm increments. The three levels of graphics/text ratio were 3:1, 1:1, and 1:3, while icon style was either flat or skeuomorphic. Results showed that button size and graphics/text ratio had significant effects on user performance in both groups, whereas icon style only had an effect in the senior group. It was observed that the elderly were fond of buttons with a larger size of 20 mm with larger texts and skeuomorphic icons, whereas the young preferred a button size of 15 mm with equal-sized graphics and text. These results may help to improve the accessibility and usability of smart home interface design.
基于触摸技术的智能家居越来越普及，因为它们可以帮助人们独立生活，特别是对于老年人来说。本研究旨在探讨智能家居界面中按钮特征（即按钮大小、图形/文本比例和图标样式）对两个年龄组用户性能的影响。年轻组（n=15）和老年组（n=15）的参与者完成了点击任务。按钮大小从 10 毫米到 25 毫米，间隔 5 毫米。图形/文本比例有 3:1、1:1 和 1:3 三个级别，而图标样式为扁平或拟物化。结果表明，按钮大小和图形/文本比例对两个组的用户性能都有显著影响，而图标样式仅对老年组有影响。观察到老年人喜欢大小为 20 毫米、文字较大且拟物化图标的按钮，而年轻人则更喜欢大小为 15 毫米、图形和文字大小相等的按钮。这些结果可能有助于提高智能家居界面设计的可访问性和可用性。
