Abstract

An open virtual input and display device and method thereof, in which a micro project module projects various input interface images; at the same time a detecting light source emit module emits a detecting beam above an image frame; based upon the reflective beam, a detecting light source receive module acquires the input action of a user on the image; a recognition module converts the acquired input action into an operation command with a recognition function; a switch module transforms and loads the corresponding input interface image data and the recognition function according to the operation command; and an application information database is used to store multiple application information files.

Claims

1. An open virtual input and display device applied to a plurality of master devices as an input and project display device respectively, comprising:

a micro project module for projecting a projection image of a visible light;

a detecting light source emit module for emitting a detecting beam above the projection image for detection;

a detecting light source receive module for receiving a reflected beam of the detecting beam;

a recognition module for determining a keystroke and a coordinate position of the reflective region produced by the keystroke by the reflected beam, and bringing the coordinate position in a recognition function to convert it into an operation command;

an application information database for storing a plurality of application information files;

a control module for controlling the operation of each of the modules and a data delivery, and determining whether the operation command is the switch connection or the delivery to each of the master devices;

a switch module for switching each of the master devices according to the operation command of the switch connection, and loading a projection image data and a recognition function corresponding to the master device from the application information database; and

an output-input module for receiving the input corresponding data of each of the master devices, and outputting the operation commands for each of the master devices.

2. The open virtual input and display device according to claim 1, wherein the recognition function is achieved with a function comparison table.

3. The open virtual input and display device according to claim 2, wherein the function comparison table comprises a coordinate field and an operation command field.

4. The open virtual input and display device according to claim 1, wherein each of the application information files comprises a projection image data and the corresponding recognition function thereof.

5. The open virtual input and display device according to claim 1, wherein the micro project module projects a screen display frame of the master device.

6. The open virtual input and display device according to claim 1, wherein the connection channel is established by a blue tooth transmission, a wireless network, a radio, or any combination thereof.

7. The open virtual input and display device according to claim 1, wherein the coordinate position of the reflective region is calculated with a small unit block as a basic unit.

8. The open virtual input and display device according to claim 1, wherein the switch module further comprise a pair module for recognizing each of the master devices and establishing the setup of a plurality of connection channels to deliver data.

9. The open virtual input and display device according to claim 8, wherein the pair module further comprises a basic menu for recording a plurality of master devices which pairing setup successfully after recognition.

10. The open virtual input and display device according to claim 9, wherein the basic menu further comprises a setup parameter for establishing each of the connection channels with each of the master devices.

11. The open virtual input and display device according to claim 1, wherein the projection image comprises an icon image for switching a catalog of the master devices.

12. A method of an open virtual input and display, which is applied to a plurality of master devices as an input device respectively, the method comprising the steps of:

projecting a projection image of a visible light of a master device onto a physical plane, and emitting a detecting beam above the projection image for detection;

receiving a detecting beam reflected from a reflective region above the projection image by a user;

calculating a coordinate of the reflective region and converting it into an operation command with an recognition function of the master device;

determining the type of the operation command, if the operation command is for switching the master device, then searching a corresponding application information file from an application information database for loading; and

transforming the projected projection image according to the corresponding application information file and loading a corresponding recognition function.

13. The method of an open virtual input and display according to claim 12, wherein if the operation command is an input command of the master device, it will be delivered to the master device, such that the master device takes the corresponding action.

14. The method of an open virtual input and display according to claim 13, wherein the way of the delivery is a blue tooth transmission, a wireless network, a radio, or any combination thereof.

15. The method of an open virtual input and display according to claim 12, wherein the projection image comprises an icon image for switching a catalog of the master device.

16. The method of an open virtual input and display according to claim 12, wherein a coordinate of the reflective region is calculated with a small unit block as a basic unit.

17. The method of an open virtual input and display according to claim 12, further comprising loading the connection setup of the master device, when switching the master device.

18. The method of an open virtual input and display according to claim 17, wherein the establishment of the connection setup of the master device further comprises the steps of:
