The study on design speech-control powerpoint presentation tool

This paper was mainly exploring the important tool for many people who were exchanging knowledge especially proceeding power-point presentation as one auxiliary tool. The lecturer´s most proper position should be between the audience and screen of power-point and this location is far away the mouse or keyboard, so if we have designed one facility with wireless control and could be controlled with speech-recognition function so that users need not rush between the screen and computer. Today some identical products with RF and push function on the power-point pen that needs users to pre-learn the functions and those usage often caused errors especially in the dark environment, so in this paper we combined WSN ZigBee modules with speech-recognition function MPU to design the creative product, so to called “Hi-TEC ZigBee remote-controller of Power-Point presentation”.
