Finger tracking

摘要

The description relates to smart rings. One example can include a finger band configured to accommodate a user's finger. This example can also include a set of pressure sensors positioned on an inner surface of the finger band and configured to sense changes to tendons of the user's finger as pressure differentials and to output associated signals. The example can further include a gesture component configured to interpret the signals from the set of pressure sensors to identify individual actions performed by the user's finger.

主权项

1. A smart ring device, comprising:
a finger band configured to accommodate a user's finger; at least one pressure sensor secured to the finger band in a manner that can detect pressure imparted by a tendon passing through the finger band during performance of actions by the user's finger; and, a gesture component configured to:
perform an analysis of pressure signals from the at least one pressure sensor indicating that the tendon has imparted pressure on the at least one pressure sensor; andbased at least on the analysis of the pressure signals indicating that the tendon has imparted pressure on the at least one pressure sensor, detect that the user's finger is touching a surface of another device.
