Abstract

A method, system, and related device for operating a display device are disclosed. The method includes: a control device transmitting the directional light to the display device when detecting a key thereof is pressed, and transmitting the collected intensity data of the first reflected light and the key information to a light tracking system; the light tracking system matching a corresponding coordinate position according to the received intensity data of the first reflected light and the known current distance between the control device and the display device, from the preconfigured reflected light intensity corresponding to the distances between the control device and the coordinate positions of various directional points on display device at the distance, then executing a corresponding operation on an area of the display device corresponding to the coordinate position in conjunction with the key information, and reflecting an operation result on the display device.

First claim

What is claimed is:

1. A method for operating a display device, comprising:
configuring a table of various data of intensity of reflected light on a light tracking system when a control device is at various different distances from the display device, wherein said data of intensity of reflected light in said table correspond to coordinate positions on the display device, and said reflected light corresponds to a directional light that is sent from the control device to a control area on the display device and reflected from the display device;
the control device emitting the directional light to the display device when detecting a key thereof is pressed and the directional light being reflected from the display device and forming a first reflected light;
the control device receiving said first reflected light and collecting data of intensity of said first reflected light and transmitting the data of intensity of the first reflected light and information of the pressed key to the light tracking system;
the light tracking system matching a corresponding coordinate position on the display device from said table of various data of intensity of reflected light according to the data of intensity of said first reflected light and a current distance between the control device and the display device, executing a corresponding operation in an area corresponding to the coordinate position of the display device in conjunction with the information of the pressed key, and reflecting an operation result on the display device.

2. The method according to claim 1 , further comprising the light tracking system determining the current distance between the control device and the display device, wherein determining the current distance comprises:
when a position of the control device is used for the first time, the control device emitting the directional light to a specified area on the display device, and transmitting collected data of intensity of a second reflected light to the light tracking system;
the light tracking system determining the current distance between the control device and the display device according to the received data of intensity of the second reflected light and a preconfigured corresponding relationship between the intensity of the reflected light and a distance between the control device and the specified area.

3. The method according to claim 2 , wherein, before the control device emitting the directional light to the specified area on the display device, the method further comprises:
the display device displaying a position of the specified area, and prompting a user to use the control device to emit the directional light to the position where the specified area is located.

4. The method according to claim 3 , wherein, there are at least three beams of directional light emitted by the control device to the display device, wherein one beam of directional light is used as aiming light and the other two beams of the directional light are used as auxiliary light, and light sources of all the three beams of the directional light are separately arranged at a certain angle.

5. The method according to claim 2 , wherein, there are at least three beams of directional light emitted by the control device to the display device, wherein one beam of directional light is used as aiming light and the other two beams of the directional light are used as auxiliary light, and light sources of all the three beams of the directional light are separately arranged at a certain angle.

6. The method according to claim 1 , wherein, there are at least three beams of the directional light emitted by the control device to the display device, wherein one beam of the directional light is used as aiming light and the other two beams of the directional light are used as auxiliary light, and light sources of all the three beams of the directional light are separately arranged at a certain angle.

7. The method according to claim 1 , further comprising:
the light tracking system equally dividing the display device into multiple areas according to information about size and resolution of the display device, and representing each area by using a central point of each area as a directional point of the area.

8. The method according to claim 1 , wherein,
transmitting the collected data of intensity of the first reflected light to the light tracking system comprises:
after the control device converts and amplifies the collected first reflected light, outputting data for representing the reflected light intensity.

9. The method according to claim 1 , further comprising:
after the light tracking system receives the data of intensity of the first reflected light, judging validity of the data of intensity of the first reflected light, and
when determining that the data is valid, executing subsequent processes.

10. A system for operating a display device, comprising a control device and a light tracking system; wherein,
the control device is configured to
emit directional light to the display device when detecting a key thereof is pressed, the directional light being reflected from the display device and forming a first reflected light,
receive said first reflected light and collect data of intensity of said first reflected light, and
transmit the data of intensity of the first reflected light and information of the pressed key to the light tracking system;

the light tracking system is configured to:
preconfigure a table of various data of intensity of reflected light on the light tracking system when a control device is at various different distances from the display device, wherein said data of intensity of reflected light in said table correspond to coordinate positions on the display device, and said reflected light corresponds to a directional light that is sent from the control device to a control area on the display device and reflected from the display device;
match a corresponding coordinate position on the display device from said preconfigured table of various data of intensity of reflected light according to the data of intensity of said first reflected light and a current distance between the control device and the display device; and
execute a corresponding operation on an area corresponding to the coordinate position of the display device in conjunction with the information of the pressed key, and reflect an operation result on the display device.

11. The system according to claim 10 , wherein,
the control device is further configured to emit the directional light to a specified area on the display device when a position of the control device is used for the first time, and transmit collected data of intensity of a second reflected light to the light tracking system;
the light tracking system is configured to determine the current distance between the control device and the display device by:
determining the current distance between the control device and the display device according to the received data of intensity of the second reflected light and a preconfigured corresponding relationship between the intensity of reflected light and distance between the control device and the specified area.

12. The system according to claim 11 , wherein, the control device is configured to emit the directional light to the display device by:
emitting at least three beams of directional light to the display device, wherein one beam of directional light is used as aiming light and other two beams of the directional light are used as auxiliary light, and light sources of all the three beams of the directional light are separately arranged at a certain angle.
