我们推出了 LightRing,这是一款环形形状的可穿戴传感器,可以感测指尖在任何表面上的二维位置,与方向或材料无关。该设备由一个用于测量手指弯曲的红外接近传感器和一个用于测量手指旋转的单轴陀螺仪组成。值得注意的是,LightRing 可以跟踪来自手指根部的微妙指尖运动,而无需对其他身体部位或环境进行检测。这可以保持手部的正常功能完好无损,并获得社会可接受的外观。我们在两种场景下的 2d 指向实验中评估 LightRing:坐下时放在桌子上,以及站立时放在腿上。我们的结果表明该设备有潜力支持各种丰富的移动输入场景。
We present LightRing, a wearable sensor in a ring form factor that senses the 2d location of a fingertip on any surface, independent of orientation or material. The device consists of an infrared proximity sensor for measuring finger flexion and a 1-axis gyroscope for measuring finger rotation. Notably, LightRing tracks subtle fingertip movements from the finger base without requiring instrumentation of other body parts or the environment. This keeps the normal hand function intact and allows for a socially acceptable appearance. We evaluate LightRing in a 2d pointing experiment in two scenarios: on a desk while sitting down, and on the leg while standing. Our results indicate that the device has potential to enable a variety of rich mobile input scenarios.
