A finger gesture recognition system is provided. The finger gesture recognition system includes one or more audio sensors and one or more optic sensors. The finger gesture recognition system captures, using the one or more audio sensors, audio signal data of a finger gesture being made by a user, and captures, using the one or more optic sensors, optic signal data of the finger gesture. The finger gesture recognition system recognizes the finger gesture based on the audio signal data and the optic signal data and communicates finger gesture data of the recognized finger gesture to an Augmented Reality/Combined Reality/Virtual Reality (XR) application.

Finger gesture recognition via acoustic-optic sensor fusion

A pose tracking system is provided. The pose tracking system includes an EMF tracking system having a user-worn head-mounted EMF source and one or more user-worn EMF tracking sensors attached to the wrists of the user. The EMF source is associated with a VIO tracking system such as AR glasses or the like. The pose tracking system determines a pose of the user's head and a ground plane using the VIO tracking system and a pose of the user's hands using the EMF tracking system to determine a full-body pose for the user. Metal interference with the EMF tracking system is minimized using an IMU mounted with the EMF tracking sensors. Long term drift in the IMU and the VIO tracking system are minimized using the EMF tracking system.
