Android Wi-Fi - Direct Technology for Remote Operation of Projectors

Abstract

Whenever an LCD projector is used for a presentation it basically needs a VGA cable between the VGA port of a computer and the projector. The projector displays whatever appears on the monitor of the PC on the projector screen. And the settings of the screen, volume and others can be changed with the help of switches placed on the projector or with the help of a wireless infrared remote. With this existing system it is difficult to maintain and control the projector with IR remote due to its line of sight property and short range it works in. This paper shows how these limitations can be overcome and also in addition ensures security from theft with the help of a PIR Sensor controlled with an android mobile via Wi-Fi. This paper aims at replacing the IR technology with WIFI technology. And the projector makes the interface wireless using a Wi-Fi protocol.
