The Effects of Touch Button Size to the Operability of Touchscreen
Jinghong Xiong,Satoshi Muraki,Kiyotaka Fukumoto 대한인간공학회 2014 대한인간공학회 학술대회논문집 Vol.2014 No.5
The present study investigated the influence of button size on the operability of a touch panel screen and compared this influence between young adults and the elderly. Twenty-one young adults (age: 22.3±1.5 years) and twenty elderly people (age: 68.1±4.9 years) operated the interface of a touch panel screen with their right index finger. It displayed 0-9 numeric square buttons at 6 different size conditions (6, 8, 10, 12, 14 and 16 mm). Smaller buttons at and below 10 mm increased the operation time and error rate, and decreased the subjective overall operability. The influence of button size was greater in the elderly than in the young adults. The reaction positions were located to the right of the center of the button, which made the reaction position approach the right outline of the button, especially for smaller buttons. These results suggest that smaller buttons should be avoided in interfaces on touch panel screens, especially those used by the elderly.
