TV remote control interfaces have gradually changed from traditional physical buttons to touch screens. However, vision, touch, and even learning abilities can become impacted with increasing age, resulting in an impaired ability to operate these interfaces and issues such as an increase in mistouches on the device and an increase in searching time. Fifty middle‐aged and older adult between the ages of 45 and 64 were recruited to investigate whether changes to the design of buttons and sound effects influence the time and error rates in interface task operations. The results showed that buttons whose background colors changed when pressed reduced task completion time, whereas buttons whose outlines thickened did not. In addition, on/off keys should be designed with reference to current remote control buttons and styled in a similar manner. Finally, sound feedback design may be added in the channel selection function to reduce operation time and error rates.

中老年人在电视遥控器中的按钮反馈设计操作

电视遥控器界面已从传统的物理按钮逐渐变为触摸屏。但是，随着年龄的增长，视觉，触摸甚至学习的能力都会受到影响，从而导致操作这些界面的能力受损，并增加诸如设备上的误触和搜索时间的增加等问题。招募了五十名年龄在45至64岁之间的中老年人，以调查按钮设计和音效的变化是否会影响界面任务操作的时间和错误率。结果表明，按下按钮时其背景颜色发生变化的按钮会减少任务完成时间，而轮廓线变粗的按钮则不会。此外，开/关键应参考当前的遥控器按钮进行设计，并以类似的方式设置样式。最后，
