  • Patent number: 11693491
    Abstract: A method includes tracking, via a positional tracker, the paired peripheral input device in a first tracking mode. The method includes obtaining sensor data from the paired peripheral input device via a communication interface. The method includes determining that the paired peripheral input device satisfies a contact criterion based on the sensor data. The contact criterion is based on a contact between the paired peripheral input device and a physical object. The method includes, in response to determining that the paired peripheral input device satisfies the contact criterion, changing the positional tracker from the first tracking mode to a second tracking mode. Tracking in the second tracking mode is based in part on a depth that indicates a distance between the electronic device and the physical object.
