Abstract

A method and a system for operating a personal computer through motion recognition are described to enable the personal computer to perform corresponding operations in response to finger motions of a user. The system comprises of a plurality of colored finger cots respectively worn on different fingers of the user; an image capturing unit for capturing digital images of all the finger cots; an motion recognition procedure for recognizing relative positions and moving directions of all the finger cots in the digital images; and a command control procedure for generating a corresponding command to control the personal computer to perform relative operations according to a set motion-command conversion table and a result of the motion recognition.

Claims

1. A method for operating a personal computer through motion recognition, wherein the personal computer captures a finger motion of a user by an image capturing unit, so as to execute a corresponding application, the method comprising:

providing a first colored finger cot and a second colored finger cot, and respectively wearing the first and second colored finger cots on the fingers of the user;

capturing a plurality of digital images comprising the colored finger cots;

setting, by the personal computer, the first colored finger cot as a first pointer and the second colored finger cot as a second pointer;

selecting a reference image and a comparison image from the digital images;

performing an motion recognition procedure, so as to output a manipulation instruction according to position and relative distance variations between the first pointer and the second pointer in the reference image and the comparison image; and

performing a command control procedure, so as to enable the personal computer to execute a corresponding application according to the manipulation instruction.

2. The method for operating a personal computer through motion recognition according to claim 1, further comprising setting a selection window, such that the motion recognition procedure is performed when it is detected that the first pointer and the second pointer exist in the selection window.

3. The method for operating a personal computer through motion recognition according to claim 1, wherein the motion recognition procedure further determines a third pointer according to a third colored finger cot, and the motion recognition procedure is used to trigger a corresponding application according to relative distance and displacement variations between the first pointer, the second pointer, and the third pointer in the reference image and the comparison image.

4. The method for operating a personal computer through motion recognition according to claim 1, further comprising establishing an motion-command instruction table before performing the motion recognition procedure, so as to record position variation combinations of the pointers in the motion recognition procedure into the motion-command instruction table, and assign a corresponding application according to the position variation combinations respectively.

5. An operating system applicable to the operating method in claim 1, wherein the system has an image capturing unit and a personal computer, and the personal computer captures a finger motion of a user by the image capturing unit, so as to execute a corresponding application, the operating system comprising:

a first colored finger cot, having a first color and capable of being worn on a finger of the user;

a second colored finger cot, having a second color and capable of being worn on a finger of the user;

an motion recognition procedure, for selecting a reference image and a comparison image from digital images, then setting the first colored finger cot worn on the finger of the user in the digital images as a first pointer, setting the second colored finger cot worn on the finger of the user as a second pointer, and outputting a manipulation instruction according to a position of the first pointer in the reference image and the comparison image, a position of the second pointer in the reference image and the comparison image, and a distance variation between the second pointer and the first pointer in the reference image and the comparison image;

a command control procedure, for enabling the personal computer to execute a corresponding application according to the manipulation instruction;

a storage unit, disposed in the personal computer, for storing the digital images, the motion recognition procedure, and the command control procedure; and

a processing unit, disposed in the personal computer, and electrically connected to the storage unit, for performing the motion recognition procedure.

6. The operating system applicable to the operating method in claim 1 according to claim 5, further comprising a third colored finger cot having a third color, wherein the motion recognition procedure sets the third colored finger cot as a third pointer, and triggers a corresponding application according to relative distance and displacement variations between the first pointer, the second pointer, and the third pointer in the reference image and the comparison image.

7. The operating system applicable to the operating method in claim 1 according to claim 6, wherein the first colored finger cot, the second colored finger cot, and the third colored finger cot are in different colors.

8. The operating system applicable to the operating method in claim 1 according to claim 5, further comprising an motion-command instruction table established by the motion recognition procedure according to position variations of the pointers.
