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.
