Abstract

An electronic reading device provides automatic adjustment of image display and key functionality. An actuator and a plurality of keys symmetrically control the electronic reading device. A built-in motion detection mechanism detects changes in the orientation of the electronic reading device. The content of the display and the functionality of the actuator and plurality of keys is automatically adjusted based on the orientation of the device such that the actuator and the plurality of keys perform identical functions in a current orientation as were performed in a previous orientation.

Claims

1. An electronic reading device, comprising:

a display;

an actuator adjacent to a first side of the display and a plurality of keys adjacent to a second side of the display, opposite the first side of the display, symmetrically controlling the electronic reading device; and

an orientation detection mechanism detecting an orientation change of the electronic reading device,

wherein, upon detecting an orientation change of approximately 180 degrees, the actuator and the plurality of keys are redefined to perform identical functions in a current orientation as were performed in a previous orientation.

2. The electronic reading device of claim 1, wherein the actuator and the plurality of keys are configured for right-handed use in the previous orientation and are reconfigured for left-handed use in the current orientation.

3. The electronic reading device of claim 1, wherein the actuator comprises a rocker bar, and pushing the rocker bar in a first direction performs a first function and pushing the rocker bar in a second direction, opposite the first direction, performs a second function.

4. The electronic reading device of claim 3, wherein the first function comprises displaying a subsequent page of an e-book and the second function comprises displaying a previous page of the e-book.

5. The electronic reading device of claim 1, wherein the plurality of keys comprises at least one of a physical key or an onscreen key.

6. The electronic reading device of claim 1, wherein the orientation detection mechanism comprises one of an accelerometer, a gyroscope or a tilt switch array.

7. The electronic reading device of claim 3, wherein the rocker bar is parallel to a longer side of the display and a length of the rocker bar is approximately equal to a length of the longer side of the display.

8. The electronic reading device of claim 1, wherein the display comprises a touch-screen interface and one of an electronic ink (e-Ink) display, a liquid crystal display (LCD) or an organic light emitting diode (OLED) display.

9. The electronic reading device of claim 1, further comprising at least one of a Wi-Fi transceiver, a Bluetooth transceiver or a cellular transceiver.

10. The electronic reading device of claim 1, further comprising a memory card slot.

11. The electronic reading device of claim 1, further comprising a light source illuminating the display.

12. A method for operating an electronic reading device, comprising the steps of:

performing a first function in response to a switch being pushed in a first direction and performing a second function in response to the switch being pushed in a second direction; and

redefining the switch such that pushing the switch in the first direction performs the second function and pushing the switch in the second direction performs the first function, upon detecting an orientation change of the electronic reading device of approximately 180 degrees.

13. The method of claim 12, wherein the first function comprises displaying a subsequent page of an e-book and the second function comprises displaying a previous page of the e-book.

14. The method of claim 12, further comprising the step of turning off a display of the electronic reading device, upon turning the electronic reading device upside down.

15. The method of claim 12, further comprising the step of entering a low power mode, upon turning the electronic reading device upside down.

16. The method of claim 12, further comprising the steps of:

recording an audio note;

associating the audio note with a particular body of text of an e-book; and

playing the audio note and displaying the particular body of text, simultaneously, in response to a user input.

17. A method for operating an electronic reading device, comprising the steps of:

displaying a subsequent page of an e-book in response to a rocker bar being pushed in a first direction;

displaying a previous page of the e-book in response to the rocker bar being pushed in a second direction, opposite the first direction;

scrolling text on a display down in response to pushing a first key;

scrolling text on the display up in response to pushing a second key;

upon detecting an orientation change of the electronic reading device of approximately 180 degrees, inverting content on the display, displaying a subsequent page of the e-book in response to the rocker bar being pushed in the second direction, displaying a previous page of the e-book in response to the rocker bar being pushed in the first direction, scrolling text on the display down in response to pushing the second key and scrolling text on the display up in response to pushing the first key.
