Abstract

The invention discloses a smart interactive projection system which comprises an infrared camera unit, a virtual interaction region, a projector unit, an infrared laser transmitter unit, a storage unit, a processing unit, a wired communication unit and a wireless communication unit. When any position of the virtual interaction region is clicked by a finger or other touch devices, the infrared camera unit detects that the optical field is blocked; the processing unit identifies the position information of the clicking event; the storage unit maps the position information under the coordinate system of the infrared camera unit into position information under the coordinate system of the virtual interaction region, and converts the clicking event into a corresponding touch event; and the corresponding touch event is transmitted to a mobile terminal or a computer through a data transmission unit. The smart interactive projection system takes the place of the traditional input devices such as a keyboard, a mouse and a touch panel, enhances the system convenience and realizes all functions of single point and multi-point touch screens.

Description

technical field [0001] The invention particularly relates to an intelligent interactive projection system. Background technique [0002] Multi-touch interactive technology is a technology realized jointly by human-computer interaction technology and hardware equipment, and can perform human-computer interaction operations on computers without traditional input devices (such as: mouse, keyboard, etc.). Multi-touch interaction technology can form a touch screen (screen, desktop, wall, etc.) or touchpad, which can accept human-computer interaction operations from multiple points on the screen at the same time. [0003] The technology began in 1982 with a multi-touch screen that sensed the pressure of an index finger, invented at the University of Toronto. In the same year, Bell Labs published the first academic literature on touch technology. [0004] In 1984, Bell Laboratories developed a touch screen that could be controlled by more than one hand to change the screen. At t...
