Methods and apparatuses for providing input for head-worn image display devices
An apparatus for use with an image display device configured for head-worn by a user, includes: a screen; and a processing unit configured to assign a first area of the screen to sense finger-action of the user; wherein the processing unit is configured to generate an electronic signal to cause a change in a content displayed by the display device based on the finger-action of the user sensed by the assigned first area of the screen of the apparatus.
1. An apparatus comprising:
a touch-sensitive display;
a feedback component configured to provide non-visual feedback; and
one or more processors that are operatively coupled to the touch-sensitive display and the feedback component and are communicatively coupled to a wearable device, the one or more processors configured to:
receive, from the wearable device, data indicating whether the apparatus is within a field of view of a camera of the wearable device or not; and
based on the data indicating whether the apparatus is within the field of view of the camera of the wearable device or not, switch between a first mode and a second mode, wherein in the first mode, the one or more processors are configured to convey one or more portions of a user interface to a user via the feedback component, wherein in the second mode, the one or more processors are configured to present the user interface on the touch-sensitive display of the apparatus without utilizing the feedback component of the apparatus, wherein the one or more processors are configured to switch to the second mode if the data indicates that the apparatus is within the field of view of the camera of the wearable device, and to switch to the first mode if the data indicates that the apparatus is outside the field of view of the camera of the wearable device.
2. The apparatus of claim 1 , wherein the feedback component is a haptic actuator.
3. The apparatus of claim 1 , wherein the feedback component is a speaker.
4. The apparatus of claim 1 , wherein user interface is a graphical user interface for controlling one or more functions of the wearable device.
5. The apparatus of claim 4 , wherein the graphical user interface comprises a plurality of graphical control elements.
6. The apparatus of claim 5 , wherein when in the mode, the one or more processors are configured to refrain from presenting one or more of the plurality of graphical control elements on the touch-sensitive display.
7. The apparatus of claim 5 , wherein when in the first mode, the one or more processors are configured to present a limited version of the graphical user interface on the touch-sensitive display.
8. The apparatus of claim 7 , wherein the limited version of the graphical user interface on the touch-sensitive display is one in which one or more of the plurality of graphical control elements are not shown, one in which brightness levels of one or more of the plurality of graphical control elements are reduced, or a combination thereof.
9. The apparatus of claim 5 , wherein when in the first mode, the one or more processors are configured to convey one or more locations on the touch-sensitive display at which one or more of the plurality of graphical control elements are otherwise presented in the second mode.
10. The apparatus of claim 9 , wherein the one or more locations on the touch-sensitive display that are conveyed in the first mode correspond to one or more outer boundaries of the plurality of graphical control elements that are otherwise presented in the second mode.
11. The apparatus of claim 5 , wherein the graphical control elements correspond to a plurality of physical user input components of a dedicated input controller that is associated with the wearable device.
12. The apparatus of claim 1 , wherein the one or more processors are configured to assign an area of the touch-sensitive display to sense different finger-gliding actions of the user.
13. The apparatus of claim 12 , wherein the apparatus is configured to monitor a peripheral part of the assigned area for provision of a control signal to operate the feedback component, wherein the peripheral part of the assigned area being monitored for provision of the control signal extends continuously across at least a majority of a side of the touch-sensitive display.
14. The apparatus of claim 1 , wherein the data comprises camera data.
15. The apparatus of claim 1 , wherein the camera is configured to view away from the user.
16. A processor-implemented method includes:
receiving, from a wearable device, data indicating whether an apparatus having a touch-sensitive display is within a field of view of a camera of the wearable device or not; and
based on the data, switching between a first mode and a second mode, wherein in the first mode, one or more portions of a user interface are conveyed to a user of the wearable device via a feedback component of the apparatus, wherein in the second mode, the user interface is presented on the touch-sensitive display of the apparatus without using the feedback component of the apparatus, wherein the second mode is switched to if the data indicates that the apparatus is within the field of view of the camera of the wearable device, and wherein the first mode is switched to if the data indicates that the apparatus is outside the field of view of the camera of the wearable device.
17. The method of claim 16 , wherein the data comprises camera data.
18. The method of claim 16 , further comprising assigning an area of the touch-sensitive display to sense different finger-gliding actions of the user.
19. The method of claim 18 , further comprising monitoring a peripheral part of the assigned area for provision of a control signal to operate the feedback component, wherein the peripheral part of the assigned area being monitored for provision of the control signal extends continuously across at least a majority of a side of the touch-sensitive display.
20. The method of claim 16 , wherein the camera is configured to view away from the user.
