Laser hand writing real-time distinguishing and recording brief reporting system

The invention is a laser handwriting real-time identifying and bulletin recording system, comprising a CPU comprising a control signal receiving module, receiving control signal through wireless control signal receiving device and connecting with a projector and a video picker; a hand-held control unit comprising a control signal transmitting module and a built display device. It uses the hand-held control unit to establish a control connection with the CPU, projects the projected data in the bulletin from the hand-held control unit through the CPU to the display device and makes laser indication operation, controls and operates by the marks of the hand-held control unit to start up a laser beam to directly mark or indicate the projected data by handwriting, starts up the video picker to pick the marked displayed data and transmits them to the CPU, operating the handwritten mark or indication contents, and records and synchronously projects these contents on the display device by the video projector.
