LIGHT-EMITTING USER INPUT DEVICE FOR CALIBRATION OR PAIRING
A light-emitting user input device can include a touch sensitive portion configured to accept user input (e.g., from a user's thumb) and a light-emitting portion configured to output a light pattern. The light pattern can be used to assist the user in interacting with the user input device. Examples include emulating a multi-degree-of-freedom controller, indicating scrolling, swiping, or other actions, indicating presence of objects nearby the device, indicating receipt of notifications, assisting pairing the user input device with another device, or assisting calibrating the user input device. The light-emitting user input device can be used to provide user input to a wearable device, such as, e.g., a head mounted display device.
1 . A light-emitting user input device for providing user input to a display system including a wearable display device, the light-emitting user input device comprising:
a plurality of interactable regions configured to receive user inputs;
a light-emitting assembly comprising a light guide; and
a hardware processor communicatively coupled to the plurality of interactable regions and the light-emitting assembly, the hardware processor programmed to:
determine an application currently being presented by the display system through the wearable display device;
determine a type of user input that is supported by the light-emitting user input device and that is usable to provide commands to the application using at least one of the plurality of interactable regions; and
instruct the light-emitting assembly to illuminate a light pattern that indicates the type of user input that is usable to provide commands to the application.
2 . The light-emitting user input device of claim 1 , wherein the light guide at least partly surrounds at least one of the plurality of interactable regions.
3 . The light-emitting user input device of claim 1 , wherein the light guide is substantially circular.

10 . The light-emitting user input device of claim 9 , wherein the arc length of at least one of the arcs is increased from approximately 0.25π to approximately 0.75π.
11 . The light-emitting user input device of claim 7 , wherein the light pattern further includes a change, over time, of a brightness of at least one of the arcs.
12 . A method performed by at least one hardware processor, the method comprising:
determining an application currently being presented through a wearable display device of a display system;
determining a type of user input that is supported by a light-emitting user input device and that is usable to provide commands to the application using at least one of a plurality of interactable regions included in the light-emitting user input device, wherein the light-emitting user input device is configured to provide user input to the display system through actuation of the plurality of interactable regions; and
instructing a light-emitting assembly of the light-emitting user input device to illuminate a light pattern that indicates the type of user input that is usable to provide commands to the application.
13 . The method of claim 12 , wherein the light pattern that indicates that at least one of the plurality of interactable regions is usable as a d-pad.
14 . The method of claim 12 , wherein the light pattern includes at least two arcs.
15 . The method of claim 14 , wherein the at least two arcs are of different colors.
16 . The method of claim 14 , wherein the light pattern further includes an increase, over time, of an arc length of at least one of the arcs.
17 . The method of claim 16 , wherein the arc length of at least one of the arcs is increased from approximately 0.25π to approximately 0.75π.
