Effect of wrist abduction on force applied and response time during touch screen mobile phone use
Journal Title: International Journal of engineering Research and Applications - Year 2017, Vol 7, Issue 6
Abstract
This study investigated the effect of wrist abduction on force applied and response time while performing the distinct tasks using touch screen mobile phone. For this study, a questionnaire was designed and subjects were asked to answer the questions on the basis of daily use of their touch screen mobile phones. On the basis of survey, the two most frequently used postures (one- handed and two handed operation of touch screen mobile phone) were selected for this study. For each case (one handed and two handed posture), three levels of wrist abduction i.e. 00 (neutral posture), 100 , and 200 were taken. Human performance as force applied and motoraction response time was recorded using oscilloscope. These observations were taken for both postures (one handed and two handed). The experimental results were analysed using ANOVA and SPSS software. The ANOVA result shows that wrist abduction angle for both postures (one- handed and two handed) has a significant effect on performance of touch screen mobile phone users. Analysis of results indicates that the two handed posture with wrist abduction 0 o offers optimum performance in this environment.
