Tracking core for providing input to peripherals in mixed reality environments
Disclosed is a self-contained, pluggable tracking system that monitors six degree of freedom (“6DoF”) without external apparatus, e.g., visual tracking or magnetic. The tracking core can communicate with a host device and with an external computing device. The external computing device can display a virtual (“VR”) or augmented reality (“AR”) world. The VR or AR world may be supplemented by overlay displays positioned according to the shape of the host device as tracked by the tracking core.
1. A device configured to physically mount to a host device, the device comprising:
a tracking core configured to generate tracking data for the device in six degrees of freedom and establish a communication link to a host device;
the tracking core further comprising:
a processor configured to determine an identity of the host device via the communication link; and
a communication interface configured to communicate the tracking data and information indicative of the identity of the host device to a processing device other than the host device over a first connection, with the processing device, that does not include the host device and is different from a second connection between the host device and the processing device.
2. The device of claim 1 , wherein the processing device is a head mounted display (HMD) device.
3. The device of claim 2 , wherein the tracking core is configured to generate tracking data in six degrees of freedom relative to the HMD.
4. The device of claim 1 , wherein the communication interface is configured to receive input data from the processing device and the processor is further configured to communicate the input data to the host device via the communication interface.
5. The device of claim 1 , wherein the information indicative of the identity of the host device identifies physical form factor characteristics of the host device.
6. The device of claim 1 , wherein the host device is any of:
a smartphone or tablet;
a game system controller;
a stylus;
a wearable accessory;
heavy equipment; or
a peripheral toy.
7. The device of claim 2 , the HMD being further configured to:
display a holographic image to a user based on the tracking data received from the device, such that the holographic image appears to the user in a position relative to the host device determined based on a position or orientation of the host device.
8. A method comprising:
generating, by an input device physically mounted on a host device, tracking data for the input device in six degrees of freedom;
establishing, by the input device, a communication link to a host device;
determining, by the input device via the communication link, an identity for the host device; and
wirelessly communicating, by the input device, the tracking data and information indicative of the identity of the host device to a processing device other than the host device over a first connection, with the processing device, that does not include the host device and is different from a second connection between the host device and the processing device.
9. The method of claim 8 , wherein the external processing device is a head mounted display (HMD) device.
10. The method of claim 9 , wherein the input device generates tracking data in six degrees of freedom relative to the HMD.
11. The method of claim 8 , said wirelessly communicating further comprising:
receiving, by the input device, input data from the processing device; and
transmitting, by the input device, the input data to the host device.
12. The method of claim 8 , wherein the information indicative of the identity of the host device identifies physical form factor characteristics of the host device.
13. The method of claim 9 , further comprising:
displaying, by the HMD device, a holographic image to a user based on the tracking data received from the input device, the holographic image appearing to the user in a position relative to the host device determined based on a position or orientation of the host device.
14. The method of claim 13 , further comprising:
receiving, by the HMD device, user input with respect to the holographic image; and
updating the holographic image based on the user input.
