Abstract

Considering the kinematic model of the hand allows for deeper understanding of target selection on the front and on the back of tablets. The authors found that the position where the thumb and fingers are naturally hovering when the device is held results in shortest target selection times. The authors broaden our understanding of that ergonomic optimum by analyzing the touch data as well as 3D data. That allows us to model the entire hand pose including finger angles, thumb angles, and orientation. The authors show how target acquisition with grasping hands is realized through bending the joints of the digits. For targets located very close to the palm of the grasping hand, the digit joints have to be bent till their limit, which is a less ergonomic motion that therefore requires longer selection times than pointing at targets with relaxed digits that are further away.

抓握手前后指片的生物力学
考虑到手的运动学模型,可以更深入地了解平板电脑正面和背面的目标选择。作者发现,当手持设备时,拇指和其他手指自然悬停的位置可以使目标选择时间最短。作者通过分析触摸数据和3D数据,拓宽了我们对人体工程学优化的理解。这使我们能够模拟整个手的姿势,包括手指的角度,拇指的角度和方向。作者展示了如何通过弯曲手指关节来实现抓握手的目标获取。对于距离手掌很近的目标,手指关节必须弯曲到极限,这是一个不太符合人体工程学的运动,因此需要更长的选择时间,而不是用放松的手指指向更远的目标。
