POINTER INCLUDING WIRELESS MOUSE FUNCTION TO FACILITATE COMMUNICATIONS SUCH AS PRESENTATION OR MEETING WITHOUT ANY ADDITIONAL HELPER

摘要

PURPOSE: A pointer combined with a wireless mouse device is provided to enable a lecturer or a meeting director to lead a meeting or presentation as changing contents of education or meeting data displayed on a screen without an aid of an assistant. CONSTITUTION: A switch(5) comprises a power supply, a laser beam switch, and left/right switches. An image generator(11) comprises a laser part(6) emitting a laser beam if power is applied from the power supply by turning on the laser beam switch, a transparent hemisphere(113) partially charged with liquid(112) in a sealed state, and a projection light(111) emitting light. A TFT(Thin Film Transistor) sensor(13) converts n image generated on a surface by the image generator into an electric signal. A controller(9) generates/outputs position coordinates by using the signal inputted from the image sensor. An RF(Radio Frequency) transmitter(17) transmits the position coordinates wirelessly.
