US Patent 11237640 Wearable device enabling multi-finger gestures

Embodiments of the subject matter described herein provide a wearable device enabling multi-finger gestures. The wearable device generally includes a first sensor, a second sensor and a controller. The first sensor can detect a first set of one or more movements of a first finger of a user. The second sensor can detect a second set of one or more movements of a second finger that is different from the first finger. The controller is configured to detect a multi-finger gesture by determining a relative movement between the first finger and the second finger based on the first and second sets of movements and to control a terminal device in association with the wearable devices based on the multi-finger gesture.
