Abstract

A display system utilizes a tilting sensor in a viewing device to transmit a wireless signal containing tilting information to a display device when a person who puts on the viewing device has tilting movements about an axis that connects between the viewing device and the display device. The display device adjusts a multimedia content displayed on a panel according to the tilting information by physically rotating the panel about the same axis or rotating the multimedia content about the same axis before the content is displayed on the panel to synchronize with the tilting angle of the viewing device.

Claims

1. A display system, comprising:

a viewing device comprising a tilting sensor and a transmitter, the tilting sensor generating tilting information of the viewing device according to an extending direction of the viewing device relative to a horizontal direction, the transmitter transmitting a wireless signal containing the tilting information; and

a display device, comprising;

a panel;

a first receiver for receiving the wireless signal from the transmitter, the display device capable of adjusting a multimedia content displayed thereon according to the tilting information;

a second receiver and a third receiver, wherein the first receiver, the second receiver, and the third receiver locate at three distinct locations of the panel for receiving the wireless signal of the viewing device to position the viewing device; and

a mechanical rotation component for rotating the panel about a first axis and a second axis respectively according to the wireless signal received by the first receiver, the second receiver, and the third receiver, and for rotating the panel about a third axis according to the tilting information;

wherein the first axis, the second axis, and the third axis are perpendicular to one another in space and the panel of the display device is rotated by the mechanical rotation component about the first axis and the second axis to directly face the viewing device.

2. The display system of claim 1, wherein the display device adjusts the multimedia content displayed thereon by rotating the multimedia content about the third axis and outputting the multimedia content on the panel;

wherein the third axis is the direction connecting between the viewing device and the display device.

3. The display system of claim 2, wherein the multimedia content is rendered by use of software 3D rendering before outputted on the panel.

4. The display system of claim 1, wherein the viewing device comprises a first lens and a second lens aligning along the extending direction.

5. The display system of claim 4, wherein the multimedia content is made up with two concurrent images designated for the first lens and the second lens of the viewing device respectively.

6. The display system of claim 1, wherein the extending direction of the viewing device has substantially the same orientation as the two eyes of a person who puts on the viewing device.

7. The display system of claim 1, wherein the viewing device is a 3D goggle and the display device is a 3D-ready (3D-ready means it is capable of displaying 3D content but it surely is also capable of dealing with ordinary media content, and I put such limitation in this dependent claim so that the invention may have a particular subject matter) television.

8. The display system of claim 1, wherein the transmitter is an IR transmitter or an RFID transmitter.

9. A viewing device for viewing a 3D multimedia content of a display device, the viewing device comprising:

a first lens and a second lens aligning along an extending direction;

a tilting sensor for generating tilting information according to the extending direction of the viewing device relative to a horizontal direction; and

a transmitter for transmitting a wireless signal containing the tilting information for being received by the display device to adjust a multimedia content displayed thereon according to the tilting information;

wherein the viewing device is capable of being positioned by the display device that uses a mechanical rotation component for rotating its panel about a first axis and a second axis respectively according to the position of the viewing device to directly face the viewing device, and the first axis is perpendicular to the second axis in space.

10. The viewing device of claim 9, wherein the extending direction has substantially the same orientation as the two eyes of a person to put on the viewing device.

11. The viewing device of claim 9, wherein the viewing device is a 3D goggle.

12. The viewing device of claim 9, wherein the transmitter is an IR transmitter or an RFID transmitter.
