Body Schema Updating in Experiencing Differently Sized Hands

在评估手持工具的可用性时，考虑用户手的大小变化是很重要的，因为可用性取决于手的大小。对于手大小不同的测试人员来说，这种评估需要花费大量的时间和成本。设计师不可能感受到测试者通过触摸和操作工具所产生的感觉，这意味着设计师无法根据测试者的感觉来提高可用性。该研究通过体验不同大小的手，向设计师提供不同大小手的评估感受。主要发现是改变手的大小来体验的有效方法。

It is important to consider the size variation of user's hands for assessing usability of hand-held tools because the usability depends on hand sizes. This assessment requires a lot of time and costs for testers whose hands are different in size respectively. It is impossible for designers to feel the tester's sensation which is induced by touching and operating the tools, which means the designers cannot improve the usability based on the tester's feeling. The study investigates experiencing differently sized hands to provide the feeling from assessment with variously sized hands to the designers. The main finding is the effective way to change hand sizes to experience.
