Abstract: “Presentation using slideshow is an effective and attractive way to convey information in the digital world. There are various means to control slides which require devices like mouse, keyboard, or laser pointer etc. The disadvantage is one must have prior knowledge about the devices in order to operate them. This paper proposes a new method to control the slides during a presentation using bare hand. This method employs hand gestures given by the user as input. The gestures are identified by counting the number of active fingers and then slides are controlled. Unlike the conventional method for hand gesture recognition which makes use of gloves or markers or any other devices, this method does not require any additional devices and makes the user comfortable. The proposed method for gesture recognition does not require any database to identify a particular gesture. It gives better accuracy even in environments illuminated with different light sources like incandescent bulb, fluorescent”
