使用鼠标的点击交互是当前桌面系统的计算机使用的组成部分。然而，与年轻用户相比，老年人在执行光标定位任务时遇到更大的困难，这可能会限制轻松有效地使用计算机。目标扩展是一种用于提高指向性能的技术，其中目标随着光标的接近而动态增长。这具有的优点是，目标保存屏幕真实的房地产在其未扩展的状态，但仍然可以提供一个更大的区域的好处clickon.This本文提出了两项研究的目标扩展与老年人和年轻的参与者，涉及多方向点选择任务与计算机鼠标。研究1比较了静态与扩展目标，研究2比较了静态目标与三种扩展技术。结果表明，扩展可以将时间提高14%，并将错误率降低50%。此外，即使扩展发生在移动的后期，也就是说，在光标已经到达扩展的目标区域之后或者甚至在光标已经到达原始目标区域之后，扩展目标也是有益的。参与者对目标扩展的主观反馈通常是有利的，这进一步支持了该技术。
Point and click interactions using a mouse are an integral part of computer use for current desktop systems. Compared with younger users though, older adults experience greater difficulties performing cursor positioning tasks, and this can present limitations to using a computer easily and effectively. Target expansion is a technique for improving pointing performance where the target grows dynamically as the cursor approaches. This has the advantage that targets conserve screen real estate in their unexpanded state, yet can still provide the benefits of a larger area to click on. This article presents two studies of target expansion with older and younger participants, involving multidirectional point-select tasks with a computer mouse. Study 1 compares static versus expanding targets, and Study 2 compares static targets with three alternative techniques for expansion. Results show that expansion can improve times by up to 14%, and reduce error rates by up to 50%. Additionally, expanding targets are beneficial even when the expansion happens late in the movement, that is, after the cursor has reached the expanded target area or even after it has reached the original target area. The participants’ subjective feedback on the target expansion are generally favorable, and this lends further support for the technique.
