Embodiment Construction

[0033] The present invention will be further described below in conjunction with the accompanying drawings.

[0034] Such as figure 1 Shown is a device applying the method of the present invention, that is, a multi-point interactive game table. Its structure includes a panel 1 and a base 2 below the panel 1. The panel 1 and the base 2 form an integral packaging structure, which improves the overall three-proof capability. The base 2 is provided with a power interface 3 . combine figure 2 As shown, the panel 1 is a square tempered glass, and the tempered glass is divided into a display area 11, four touch strip areas 12 and a shielding area 13 according to the display screen, control area and other areas. The display area 11 is located in the center of the panel, and the four touch The band area 12 is distributed around the side of the display area 11 to form an annular control area. Encapsulating the entire surface of the high-strength tempered glass panel 1 and the base 2...

Abstract

The invention relates to the field of game equipment, aims to solve the technical problems in the prior art, and designs a multi-point touch sensing method and equipment, which are accurate in touch and high in image accuracy and can be used in various places. The method comprises the following steps that: a camera and an infrared transmitting device are arranged on backs of a panel and a display device, the infrared transmitting device projects infrared ray onto the panel, a strip-shaped touch belt is formed on the front of the panel; the panel can be transmitted by the infrared ray in a region of the touch belt, and the camera transmits an image on the touch belt on the same side of the infrared transmitting device to a host; a finger touches the region of the touch belt on the front of the panel for operation, and reflects the infrared ray passing through the touch belt; the infrared ray reflected by the finger forms a white point in the image shot by the camera, and the host realizes touch by analyzing the action of the white point; and the host displays action of a computer program corresponding to the touch action through the display device.

Description

technical field [0001] The invention relates to the field of multi-touch sensing control computer or game equipment, more specifically, a multi-touch sensing method and its equipment. Background technique [0002] Multi-touch technology is a new computer or game device control method that is different from traditional mouse, keyboard and game control devices, and its application fields are very wide. [0003] In addition to traditional computers and gaming equipment, an important application of multi-touch technology is the innovation in interactive games. Interactive table or game table is a new type of service and entertainment platform, mainly used in restaurants, restaurants, KTV, bars and other places, it can be used as a platform for automatic ordering, service request, game entertainment and Internet surfing, etc., improving service The automation capabilities of suppliers also reduce operating costs and are conducive to attracting consumers. In the prior art, a var...
