Abstract

In this paper, we explore alternative TV menu control methods, focusing specifically on older users. We investigated performance and acceptance of freehand gestures by implementing several techniques and conducting a user study with 24 older adults. We expected that older adults would like gesture techniques as they are generally fun to use and easy to conduct. As a possible alternative to physical remote control, gesture techniques may also introduce some physical activity for older adults (positive health effects). In the user study, we compared four different kinds of freehand gesture interaction to control a corresponding TV menu, investigating specifically on abilities of older adults. Each of the interaction types was analyzed regarding task completion time, error rate, usability and acceptance. Results showed that directly transferring tracked hand movements to control a cursor on a TV achieved the best performance and was preferred by the users. In general, the participating older adults showed a very positive attitude towards gesture-based interactions.

评估老年人使用徒手手势控制电视菜单的表现和接受度

在本文中，我们探索替代电视菜单控制方法，特别关注老年用户。我们对24名老年人进行了一项用户研究，通过实施几种技术来调查徒手手势的表现和接受程度。我们预计老年人会喜欢手势技术，因为它们通常使用起来很有趣，也很容易操作。作为一种可能的替代物理遥控，手势技术还可以为老年人引入一些身体活动(积极的健康影响)。在用户研究中，我们比较了四种不同的徒手手势交互来控制相应的电视菜单，特别调查了老年人的能力。分析了每种交互类型的任务完成时间、错误率、可用性和可接受性。结果表明，直接将手部运动轨迹转移到电视上的光标控制可以达到最佳效果，并且是用户的首选。总的来说，参与的老年人对基于手势的互动表现出非常积极的态度。
