触摸屏在日常环境中变得越来越普遍。因此，重要的是，这项技术可以为那些有不同残疾的人所用。本研究的目的是评估在相互敲击触摸屏任务期间具有和不具有运动障碍的个体的性能和触摸特征（力、脉冲和停留时间）。37名运动控制残疾参与者和15名非残疾参与者参加了研究。结果测量包括正确敲击的次数、停留时间、施加的力和冲动。结果表明，非残疾参与者比精细运动控制障碍参与者多1.8倍，比粗大运动障碍参与者多2.8倍（p < 0.05）。此外，有粗大运动控制障碍的人表现出更长的停留时间和更大的冲动（p < 0.05）。用于激活按钮的平均力为6.2 N，但按钮激活力为0.98 N。有和没有运动控制障碍的人之间存在相互轻拍和触摸特征的差异。了解人们（包括残疾人）如何与触摸屏交互，可以让设计师和工程师最终提高触摸屏技术的可用性。(C)2012年爱思唯尔有限公司和人体工程学学会。All rights reserved.
Touch screens are becoming more prevalent in everyday environments. Therefore, it is important that this technology is accessible to those with varying disabilities. The objective of the current study was to evaluate performance and touch characteristics (forces, impulses, and dwell times) of individuals with and without a movement disorder during a reciprocal tapping touch screen task. Thirty-seven participants with a motor control disability and 15 non-disabled participants participated. Outcome measures include number of correct taps, dwell time, exerted force, and impulse. Results indicate non-disabled participants had 1.8 more taps than participants with fine motor control disabilities and 2.8 times more than those with gross motor impairments (p < 0.05). Additionally, people with gross motor control disabilities demonstrated longer dwell times and greater impulses (p < 0.05). The average force used to activate the buttons was 6.2 N, although the button activation force was 0.98 N. Differences in reciprocal tapping and touch characteristics exist between those with and without motor control disabilities. Understanding how people (including those with disabilities) interact with touch screens may allow designers and engineers to ultimately improve usability of touch screen technology.
