Please refer to FIG. 1 , which is a schematic structural diagram of a first embodiment of a multi-touch object recognition system according to the present invention, including a touch object 11 , a touch panel 12 , a database unit 13 , and a central processing unit 14 and a display unit 15.

Referring to FIGS. 2 and 3, the touch object 11 is a dinosaur-shaped styling doll having three touch ends 111 protruding from the bottom, and the touch object 11 can be touched by the touch ends 111. It has the same function as the stylus operating on the touchpad.

The touch panel 12, the database unit 13, the central processing unit 14, and the display unit 15 are integrated to form an electronic device 1 such as a tablet or a smart phone. As shown in FIG. 3, the touch panel 12 and the display unit 15 together form a touch display device 10 of the electronic device 1 for receiving the touch end 111 of the dinosaur shape touch object 11 and When the touch terminal 111 touches the touch display device 10, respective coordinate signals corresponding to the corresponding touch terminals 111 are generated. The database unit 13 is built in the memory unit of the electronic device 1, and has content information of the touch object of different dinosaur shapes and relative position information of the touch end, wherein the content information includes the dinosaur One of a pattern, a catalogue, a specification, a price, or a multimedia guide content represented by the shape touch object 11, and the touch position relative position information includes a distance between the touch terminals 111, the touch The area of the polygon formed by the bump, the shape of the polygon formed by the touch ends, or the angle formed by the two sides adjacent to each touch end of the polygon. The central processing unit 14 is a processor unit provided by the smart phone, and is connected to the touch panel 12 and the database unit 13.

In this embodiment, the content information of the dinosaur shape touch object 11 is pre-stored in the database unit 13 of the electronic device 1, that is, the catalogue specification and the selling price of the touch object, and the three-touch end 111 The relative position information of the touch end, for example, the polygonal area formed by the three touch ends 111, so that when the dinosaur shape touch object 11 is placed on the touch display device 10 of the electronic device 1, the touch is made. The touch panel of the display device 10 detects the coordinate positions of the touch points 111 on the touch display device 10 and generates coordinate signals corresponding to the coordinate positions for the central processing unit 14 to receive the coordinate signals. After calculating the polygon area formed between the coordinates, and comparing with the relative position information of all the touch ends in the database unit 13, whether the dinosaur shape touch object data having the same polygon area size is compared, and then the database unit 13 is The catalogue specifications and the selling price of the matching dinosaur shape touch object are displayed on the display unit of the touch display device 10.

In the above embodiment, the angle formed by the two adjacent sides of each touch end in the polygon formed by the three touch ends of different touch objects in the database unit 13 is compared with the coordinates. The internal angle of the polygon formed by the coordinates of the signal identifies the touch object.

In the above embodiment, the bottom of the touch object 11 can be set to two touch ends. The distance between the two touch ends of the different touch objects is stored in the database unit 13 for the central processing unit 14 to calculate the touch panel generated by the touch display device 10. After the distance between the coordinates of the two coordinate signals, the content information of the touch object corresponding to the distance between the data library unit 13 is displayed on the display unit of the touch display device 10.

In the above embodiment, the bottom of the touch object 11 can be set to three or more touch ends, and the polygonal shape formed by the touch ends of different touch objects is stored in the database unit 13 for the central processing. After receiving the coordinate signals generated by the touch panel of the touch display device 10 and determining the polygonal shape formed by the coordinates, the unit 14 displays the content information of the touch object that matches the database unit 13 and matches the shape of the polygon. On the display unit of the touch display device 10.

Referring to FIG. 4, which is a second embodiment of the present invention, based on the architecture of the first embodiment, the database unit 13, the central processing unit 14, and the display unit 15 are integrated into a personal computer. In the electronic device 2, the touch panel 21 is connected to the electronic device 2, so that when a dinosaur-shaped touch object 11 is placed on the touch panel 21, the touch panel 21 touches the touch panel 21 The touch-point coordinate signal is transmitted to the electronic device 1 for the central processing unit of the electronic device 1 to compare the position of the touch surface of the dinosaur-shaped touch object 11 in the database unit. The control content information (such as the dinosaur pattern and the name data represented by the touch object 11) is displayed on the display unit 15. In this embodiment, the content information of the touch object 11 can be a multimedia navigation content containing audio. After the central processing unit compares the dinosaur shape touch object 11 , the display unit 15 can display the content information. The dinosaur shape touch object 11 pattern and name data and the like, and the horn of the dinosaur shape touch object 11 or the background introduction and the sound guide content are played by the horn of the electronic device 2 for teaching navigation. .

In the second embodiment of the present invention, the central processing unit can continuously receive the coordinate signal of the touch object 11 from the touch panel 21, so that when the touch object 11 is displaced on the touch panel 21, the same Moving the position of the touch object image on the display unit 15 relative to the displacement path (as shown in FIG. 5); further, when the present invention is combined with a game device having a game target, and the content of the touch object When the information indicates the attribute of the game target, the game object can be controlled by operating the touch object on the touch panel, for example, the movement of the game object to add fun to the game.

Therefore, the present invention can be increased by changing the number and relative positions of the touch ends. The variety of touch objects enables touch devices such as smart phones or tablets to develop a variety of application methods, and has multiple operational modes and can be extended to different application areas, such as the sale of goods, various types of A brief introduction to the exhibition and the manipulation of the game program.

In summary, according to the above disclosure, the present invention can achieve the intended purpose of the invention, and provide a touch electronic device capable of detecting the relative positional relationship of the touch terminals of the touch object and displaying the touch object. Content information, in order to increase the application of the touch-sensitive electronic device, the multi-point touch object identification system is of great value in the industry, and the invention patent application is filed according to law.
