Abstract

A head-mounted display device having an interactive function is provided. The head-mounted display device includes a play unit, a display unit and a sensor unit. The play unit plays a portion of an image on the display unit. The display unit displays the image being played. The sensor unit senses a movement and a movement direction of the head-mounted display device. The play unit further adjusts the displayed portion of the image being played according the movement and the movement direction of the head-mounted display device.

Claims

1. A head-mounted display device having an interactive function, comprising:

a display unit;

a play unit able to play a portion of an image on the display unit; and

the display unit able to display the image being played; and

a sensor unit to sense a movement and a movement direction of the head-mounted display device relative to an initial position of the head-mounted display device;

wherein, the play unit further is to adjust the displayed portion of the image being played according the sensed movement and the movement direction from the sensor unit.

2. The head-mounted display device as described in claim 1, further comprising an interface, wherein the sensor unit is connected to the head-mounted display device through the interface when the sensor unit is an independent sensor.

3. The head-mounted display device as described in claim 1, wherein the play unit is further configured for detecting a format of the image being played, and comparing the detected format with a predetermined format to determine whether to adjust the image according the sensed movement and the movement direction of the head-mounted display device.

4. The head-mounted display device as described in claim 1, wherein the sensor unit comprises an orientation sensor and a movement sensor, the orientation sensor is able to sense the movement direction of the head-mounted display device when moving, and the movement sensor is able to sense the movement of the head-mounted display device when moving.

5. The head-mounted display device as described in claim 4, wherein the orientation sensor is an electronic compass.

6. The head-mounted display device as described in claim 4, wherein the movement sensor is a combination of a tri-axial acceleration transducer and a gyroscope.

7. The head-mounted display device as described in claim 4, wherein the movement sensor is a combination of three acceleration transducers and a gyroscope.

8. The head-mounted display device as described in claim 1, further comprising a transfer switch which switches the sensor unit between an enable state and a disable state.

9. A method having an interactive function implemented by a head-mounted display device, the method comprising:

sensing a movement and a movement direction of the head-mounted display device relative to an initial position of the head-mounted display device;

adjusting a portion of an image being played according the sensed movement and the movement direction; and

displaying the image being played.
