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.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>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.
