Projection system with interaction function

Abstract

The invention discloses a projection system with an interaction function. The projection system comprises a projector with a wireless network connecting module, a remote server, a signal transmitter, and a projection screen. The projector projects a file to the projection screen. The signal transmitter transmits light to the projection screen, and the light from the signal transmitter has the function of indication or information inputting. A light spot recognition module captures and recognizes light signals from the signal transmitter to the projection screen. An information processing unit stores a list of information system message events corresponding to the light signals. A microprocessor triggers the information system message events corresponding to the light signals to correct the file on the projection screen. The projector uploads the corrected file to the remote server. The projector is also capable of correcting the file on the projection screen through the signal transmitter and uploading the corrected file to the remote server; the corrected file is ready to be downloaded by terminals except the projector; the information interaction between the projector and the remote server is achieved.

Description

technical field [0001] The present invention relates to a projector system, in particular to a projector system including a remote server. The projection system can project files and transmit files to the remote server to realize file interaction between the projector and the remote server. Background technique [0002] A projector can project and display enlarged images and is a common large-screen display device in conference rooms. According to different display technologies, traditional projectors are mainly divided into three types: DLP (Digital Optical Processing Projector), LCD (Liquid Crystal Projector), and CRT (Cathode Ray Tube Projector), while the recently emerged LCoS (Liquid Crystal on Silicon) Or LED projectors have the characteristics of high light efficiency, small size, high resolution, bright colors, etc., and are an ideal projection display technology. [0003] Most traditional projectors do not have the function of network connection, and are mainly con...

Problems solved by technology

Can't work if the user using the projector can't have a removable storage device or computer with them to store their files on

[0004] Furthermore, the current projectors only project the stored images and only have a display function. When asked to modify them, they need to be controlled from a computer connected to the projector, and the operation is cumbersome.
