Abstract

In one embodiment, a method for providing feedback for a page turn requested on a device is provided. The device may be an electronic book (e-book) device or another device that is configured to display electronic documents. A movement on the display of the device is detected. The method determines that a page turn of the document is being requested based on the movement on the display. The method determines a light-based feedback to indicate that a page turn is being processed. The computing time to process a page turn and display a new page may be slow as perceived by the user. Accordingly, the light-based feedback is used to indicate to the user that the page turn has been received. A plurality of light sources are used to provide the light-based feedback based on a location of the movement. For example, as a user swipes a finger across a display, light sources that follow the motion of the finger are illuminated to simulate a page turn.

Claims

1. A method for providing feedback for a page turn on an electronic ink device, the method comprising:

detecting a movement on a display of the electronic ink device while displaying an electronic document on the display;

determining that a page turn of the electronic document is being requested based on the movement on the display;

determining a portion at least two light sources of a plurality of light sources of the display to provide light-based feedback based on a position and direction of the detected movement on the display; and

illuminating the at least two light sources of the plurality of light sources in sequence, the sequence corresponding to the position and the direction of the detected movement, wherein the light based feedback simulates the page turn and indicates that the page turn has been received and is being processed.

2. The method of claim 1, wherein the movement detected on the display is in a first direction, wherein the light-based feedback comprises changing a characteristic of the at least two light sources of the plurality of light sources to follow the detected movement in the first direction.

3. The method of claim 2, wherein the at least two light sources that have characteristics changed correspond to a position of the detected movement.

4. The method of claim 1, wherein the light-based feedback comprises turning the plurality of light sources on or off to indicate the page turn has been received.

5. The method of claim 1, wherein the light-based feedback comprises altering an intensity of the plurality of light sources to indicate the page turn has been received.

6. The method of claim 1, wherein detecting the movement comprises detecting a touch on the display in a first direction.

7. The method of claim 1, wherein a controller is used to determine the page turn is being requested and a driver of the plurality of lights is used to output the light-based feedback.

8. The method of claim 7, wherein the controller is separate from a CPU processing the page turn request.

9. The method of claim 1, wherein the plurality of light sources is positioned along an edge of the display.

10. The method of claim 1, wherein the plurality of light sources is positioned along a bottom edge and/or a side edge of the display.

11. An electronic ink device configured to provide feedback for a page turn comprising:

one or more processors operable to;

detect a movement on a display of the electronic ink device while displaying an electronic document on the display, wherein the electronic document is displayed using an electronic ink display panel layer and the display is illuminated using a plurality of light sources in a light guide panel layer;

determine that a page turn of the electronic document is being requested based on the movement on the display;

determine at least two light sources of the plurality of light sources to provide light-based feedback based on a position and direction of the detected movement on the display, wherein the at least two light sources of the plurality of light sources are dispersed in the light guide panel layer to provide the light-based feedback for the page turn; and

illuminating the at least two light sources of the plurality of light sources in sequence, the sequence corresponding to the position and the direction of the detected movement, wherein the light-based feedback simulates the page turn and indicates that the page turn has been received and is being processed.

12. The electronic ink device of claim 11, wherein the movement detected on the display is in a first direction, wherein the light-based feedback comprises changing a characteristic of light sources in the plurality of light sources to follow the movement in the first direction.

13. The electronic ink device of claim 12, wherein light sources that have characteristics changed correspond to a position of the detected movement.

14. The electronic ink device of claim 11, wherein the light-based feedback comprises turning the plurality of light sources on or off to indicate the page turn has been received.

15. The electronic ink device of claim 11, wherein the light-based feedback comprises altering an intensity of the plurality of light sources to indicate the page turn has been received.

16. The electronic ink device of claim 11, wherein the one or more processors are further operable to detect a touch on the display in a first direction.

17. The electronic ink device of claim 11, wherein the one or more processors are used to determine the page turn is being requested and a driver of the plurality of lights is used to output the light-based feedback.

18. The electronic ink device of claim 17, wherein the one or more processors are separate from a CPU processing the page turn request.

19. The electronic ink device of claim 11, wherein the determined portion of the plurality of light sources is positioned along an edge of the display.

20. An apparatus configured to provide feedback for a page turn on an electronic ink device, the apparatus comprising:

a touch sensor detector configured to detect a movement on a display of the electronic ink device while displaying an electronic document on the display, wherein the electronic document is displayed using an electronic ink display panel layer and the display is illuminated using a plurality of light sources in a light guide panel layer;

a controller operable to;

determine that a page turn of the electronic document is being requested based on the movement on the display;

a light driver configured to;

determine at least two light sources of the plurality of light sources to provide light-based feedback based on a position and direction of the detected movement on the display, wherein the at least two light sources of the plurality of light sources are dispersed in the light guide panel layer to provide the light-based feedback for the page turn; and

illuminating the at least two light sources of the plurality of light sources in sequence, the sequence corresponding to the position and the direction of the detected movement, wherein the light-based feedback simulates the page turn and indicates that the page turn has been received and is being processed.
