随着功能的改进和成本的降低,触摸技术变得越来越普遍。因此,重要的是,这项技术可以为具有不同能力的用户所用。本研究的目的是调查不同运动能力的个体的按钮和间隙大小对性能的影响。有(n=38)和没有(n=15)运动控制残疾的参与者完成了数字输入任务。按钮尺寸范围从10到30毫米,间隙尺寸为1或3毫米。结果表明,随着按钮尺寸的增加,失误,错误和完成任务的时间减少。非残疾组的性能在钛板尺寸20 mm时达到稳定,如果观察到较大钛板尺寸的任何增益,则具有最小增益。相比之下,残疾人组的表现随着按钮尺寸的增加而继续改善。间隙大小不影响用户性能。这些结果可能有助于提高触摸技术的可访问性。
Touch technology is becoming more prevalent as functionality improves and cost decreases. Therefore, it is important that this technology is accessible to users with diverse abilities. The objective of this study was to investigate the effects of button and gap size on performance by individuals with varied motor abilities. Participants with (n=38) and without (n=15) a motor control disability completed a digit entry task. Button size ranged from 10 to 30 mm and gap size was either 1 or 3 mm. Results indicated that as button size increased, there was a decrease in misses, errors, and time to complete tasks. Performance for the non-disabled group plateaued at button size 20mm, with minimal, if any gains observed with larger button sizes. In comparison, the disabled group’s performance continued to improve as button size increased. Gap size did not affect user performance. These results may help to improve accessibility of touch technology.
