Abstract

An electrical device having a projection device for projecting image information onto a projection surface disposed externally to the telecommunication device; an inertial sensor to detect a movement of the electrical device; the electrical device being operable in a first operating mode so that the projection of the image information onto the projection surface follows a movement of the electrical device with a movement component in a plane disposed in parallel to the plane of the projection surface; the electrical device being operable in a second operating mode so that, in spite of the electrical device'"'"'s movement, the projection of the image information onto the projection surface with a movement component in a plane parallel to the plane of the projection surface is at least partially substantially fixed; the electrical device being configured so that its movement in the second operating mode is interpreted as a user input.

Claims

1. An electrical device, comprising:

a projection device to project image information onto a projection surface disposed externally to the electrical device;

an inertial sensor to detect a movement of the electrical device;

wherein the electrical device is operable in a first operating mode so that the projection of the image information onto the projection surface follows a movement of the electrical device with a movement component in a plane disposed in parallel to the plane of the projection surface,

wherein the electrical device is operable in a second operating mode so that, in spite of the movement of the electrical device, the projection of the image information onto the projection surface with a movement component in a plane disposed in parallel to the plane of the projection surface is at least partially substantially fixed, and

wherein the electrical device is configured so that the movement of the electrical device is interpreted in the second operating mode as a user input.

2. The electrical device of claim 1, wherein the projection of the image information onto the projection surface is increased or reduced in size in the second operating mode relative to the first operating mode.

3. The electrical device of claim 1, wherein in the second operating mode, in response to the movement of the electrical device having a movement component in a plane disposed in parallel to the plane of the projection surface, a portion of the image information disappears on the projection surface, and a portion of the image information appears on the projection surface.

4. The electrical device of claim 1, wherein in the second operating mode, the projection of the image information onto the projection surface is at least partially substantially fixed in spite of the movement of the electrical device, and wherein pointer projection information is followed by the movement of the electrical device with a movement component in a plane disposed in parallel to the plane of the projection surface.

5. The electrical device of claim 1, wherein the electrical device is a telecommunication device, in particular, a stationary or a portable telecommunication terminal, in particular, in the form of a portable computer or a portable cell phone.

10. The electrical device of claim 1, wherein the electrical device is a telecommunication device.

11. The electrical device of claim 1, wherein the electrical device is a stationary telecommunication terminal or a portable telecommunication terminal.

12. The electrical device of claim 1, wherein the electrical device is a portable computer or a portable cell phone.

6. A method for operating an electrical device, the method comprising:

in a first operating mode of the electrical device, projecting from a projection device a first version of the image information onto the projection surface, wherein the electrical device has an inertial sensor and the projection device to project image information onto the projection surface disposed externally to the electrical device, wherein the electrical device is operable in the first operating mode so that the projection of the image information onto the projection surface follows a movement of the electrical device with a movement component in a plane disposed in parallel to the plane of the projection surface, and wherein the electrical device is operable in a second operating mode so that the projection of the image information onto the projection surface is at least partially substantially fixed in spite of the movement of the electrical device;

in the second operating mode, the electrical device is moved in the plane in parallel to the plane of the projection surface;

detecting a movement of the electrical device by the inertial sensor; and

interpreting the movement of the electrical device in the second operating mode as a user input.

7. The method of claim 6, wherein in the second operating mode, in response to the movement of the electrical device having a movement component in a plane disposed in parallel to the plane of the projection surface, a portion of the image information disappears on the projection surface, and a portion of the image information appears on the projection surface.

8. The method of claim 6, wherein in the second operating mode, the projection of the image information onto the projection surface is at least partially substantially fixed in spite of the movement of the electrical device, and wherein a pointer projection information follows the movement of the electrical device with a movement component in a plane disposed in parallel to the plane of the projection surface.

9. The method of claim 6, wherein the electrical device is a telecommunication terminal.
