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.

Due to its simple structure, the linear induction motor provides a linear driving force without any intermediate conversion devices. Linear induction motors are gradually used in various applications, including rail transit and the national defense industry. However, linear induction motors are affected by the end-effect phenomenon and suffer from problems such as low efficiencies and low power factors. In this paper, to optimize the performance of short primary double-sided linear induction motors (SP-DLIMs), first, a new analytical model is established based on an equivalent circuit considering both transverse and longitudinal end effects. Second, to analyze the impact of main parameters on the output characteristics of SP-DLIMs, a simple iterative design method (IDM) is presented. Third, a multi-objective optimal design method is proposed to optimize the efficiency, power factor and tooth weight of SP-DLIMs, with proposed design constraints and four different optimization problems. Moreover, an improved differential evolutionary (IDE) algorithm is proposed to optimize the design. A comparison of the results proved that the IDE yielded a competitive performance to those of other advanced heuristic algorithms. Finally, a three-dimensional time-stepping finite-element method was utilized to verify the validity of the optimization results.
