Abstract

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 or swiping 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.

First claim

What is claimed is:

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, including a central touch surface, configured to receive user inputs;
a light-emitting assembly comprising a light guide outside of and surrounding the central touch surface; and
a hardware processor communicatively coupled to the plurality of interactable regions and the light emitting assembly, the hardware processor to:
detect an actuation of the light-emitting user input device by a user of the wearable display device;
access contextual information indicating a virtual object that is being presented through the wearable display device and that the user is currently interacting with;
determine an interactable region among the plurality of interactable regions corresponding to the actuation;
based at least partly on the contextual information, translate the actuation into a user input for performing a user interface operation associated with the virtual object being interacted with, wherein the user interface operation is based at least on the virtual object being interacted with, a type of the actuation, and the interactable region associated with the actuation; and
instruct the light emitting assembly to illuminate a light pattern in response to the user input.

2. The light-emitting user input device of claim 1 , wherein
the plurality of interactable regions comprises
a first interactable region associated with the light guide and
a second interactable region associated with the central touch surface.

3. The light-emitting user input device of claim 2 , wherein in response to a detection that the user actuated the first interactable region, the hardware processor is programmed to cause the light emitting assembly to illuminate a first light pattern associated with the user input in the first interactable region, and wherein in response to a detection that the user actuated the second interactable region, the hardware processor is programmed to cause the light emitting assembly to illuminate a second light pattern associated with the user input in the second interactable region.

4. The light-emitting user input device of claim 1 , wherein the light pattern is determined based at least partly on the contextual information.

5. The light-emitting user input device of claim 1 , wherein the actuation comprises at least one of: a swipe, a tap, a press, or a touch gesture.

6. The light-emitting user input device of claim 1 , wherein the light pattern comprises an arcuate region having one or more of a color, an arcuate length, or a visual effect.

7. The light-emitting user input device of claim 1 , wherein the hardware processor is further programmed to communicate with display system causing the display system to perform the user interface operation based on the user input.

8. A method comprising:
under control of a hardware processor:
detecting an actuation of a light-emitting user input device by a user of a wearable display device,
wherein the light-emitting user input device is configured to provide user input to a display system including the wearable display device, and
wherein the light-emitting user input device comprises a plurality of interactable regions, including a central touch surface, configured to receive inputs, and a light emitting assembly comprising a light guide outside of and surrounding the central touch surface;
accessing contextual information indicating a virtual object that is being presented through the wearable display device and that the user is currently interacting with;
determining an interactable region among the plurality of interactable regions corresponding to the actuation;
translating the actuation into a user input for performing a user interface operation based at least on the contextual information, wherein the user interface operation is associated with the virtual object being interacted with, and wherein the user interface operation is determined based at least on the virtual object being interacted with, a type of the actuation, and the interactable region associated with the actuation; and
causing the light emitting assembly to illuminate a light pattern in response to the user input.

9. The method of claim 8 , wherein the plurality of interactable regions comprises a first interactable region supporting a first type of user input and a second interactable region supporting a second type of user input.

10. The method of claim 9 , wherein in response to a detection that the user actuated the first interactable region, the hardware processor is programmed to cause the light emitting assembly to illuminate a first light pattern associated with the user input in the first interactable region, and wherein in response to a detection that the user actuated the second interactable region, the hardware processor is programmed to cause the light emitting assembly to illuminate a second light pattern associated with the user input in the second interactable region.

11. The method of claim 9 , wherein at least one of the first type of user input or the second type of user input is dependent on the contextual information, and wherein the contextual information comprises at least one of a type of application with which a user is interacting, available user inputs supported by the plurality of interactable regions, or a virtual environment of the user.

12. The method of claim 8 , wherein the light-emitting user input device comprises the central touch surface which is divided into one or more interactable regions.

13. The method of claim 8 , wherein the light pattern is determined based at least partly on the contextual information.

14. The method of claim 8 , wherein the plurality of interactable region comprises the light emitting assembly of the light-emitting user input device.

15. The method of claim 8 , wherein the actuation comprises at least one of: a swipe, a tap, a press, or a touch gesture.

16. The method of claim 8 , wherein the light pattern comprises an arcuate region having one or more of a color, an arcuate length, or a visual effect.
