WIRELESS CONTROL OF POWERPOINT SLIDES THROUGH MOBILE CAMERA USING IMAGE PROCESSING BASED MATLAB SOFTWARE

ABSTRACT Presentation using slideshow is an effective and attractive way to convey information in the digital world. PowerPoint slides can be controlled by various devices like keyboard, mouse, laser pointer etc. Here we are proposing a new method to control the slides during a presentation using mobile camera. This is all about controlling of PowerPoint presentation wirelessly with the help of a colour paper and a mobile camera which is connected with the computer through software called smartcam and with the help of smartcam software the image processing will be done through MATLAB and with the help of MATLAB the PowerPoint slide will change. Various devices are available which can be used to control slides wirelessly such as Bluetooth mouse but a Bluetooth mouse is costly and this technique eradicates the use of Bluetooth mouse. Since there is no such use of any hardware except mobile phone which is available with everyone now days, so it gives a cost effective way to control slides wirelessly.
