摘要
探讨在指点定位中目标方向、大小和距离对食指和拇指操纵追踪球的运动时间的效应 ,并由此建立了两种追踪球的菲茨模型。用绩效指数比较了不同指点装置的操作绩效 ,对追踪球的优化设计提出了建议。
The study examined the effect of the target direction,size and distance on movement time (MT) of the index finger operating and thumb operating trackballs in pointing and dragging tasks.Based on experimental results,the Fitts' models of the two trackballs were built.According to index of performance,the operation performance of different pointing devices was compared.The implication of the results to the optimal ergonomic design of trackball was also discussed.
