Multi-point touch sensing method and equipment

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 displaydevice, 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 ofthe 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...

Problems solved by technology

The use of backlight sensing needs to add sensing elements when producing LCD panels. This kind of large screen with multi-touch is very expensive and cannot be customized. It also requires fingers to directly touch the screen, which has very high requirements for the use environment. Currently Still unable to promote app

In addition, for the side light sensing technology, since the light-emitting element is arranged on the edge of the table, it is very easy to damage, and the waterproof performance is not good, and the table protrudes higher than the edge of the panel, which is not convenient for cleaning and use, which brings disgust to the user. Effect

Moreover, the positioning of the side light sensing technology is very poor, which cannot meet the requirements of many games.
