FUNCTION COMMAND SYSTEM, FUNCTION COMMAND DEVICE, FUNCTION COMMAND ANALYSIS SYSTEM, PRESENTATION SYSTEM, AND COMPUTER READABLE MEDIUM

摘要

A function command analysis system includes an image input unit, a position information extraction unit, a function command specification unit and a function command output unit. The image input unit inputs an image containing an image generated by light emitted from a light emission device. The position information extraction unit extracts position information of the image, which is generated by the light emitted from the light emission device emits, from the image input by the image input unit. The function command specification unit extracts a mode of the image, which is generated by the light emitted from the light emission device, from the image input by the image input unit to specify a function command input by an operator. The function command output unit outputs the position information extracted by the position information extraction unit and the function command extracted by the function command specification unit.
