DEVELOPMENT OF LOW COST amp; PORTABLE MODULE FOR VGA PROJECTORS BY USING MOBILE PHONE amp; FPGA

摘要

While giving Business Presentations or Presentations in Auditorium and Classrooms, use of VGA based Projectors are common. This necessitates the use of a Computer or a Laptop which acts as an interface between the Presenter and the Projector. This Invention eliminates the need for the Computer or Laptop for the purpose of presentation. In addition to eliminating Laptop, this invention also eliminates the need for external slide switching device and laser pointer device commonly used while giving presentations in projectors. This module include an FPGA based System connected to a Bluetooth Receiver. User is required to transfer his PowerPoint Presentations or PDF Files or Image files into a Mobile Phone having Bluetooth. While giving presentations, the file data is transferred into the compact portable module connected to the projector using a Java based mobile application developed specifically for this device and the same application can be used for switching between different pages or slides in the presentation. The application also provides the user to use the mouse pointer or the touch screen based pointer on the screen of the phone to act as a laser pointer on the projection. The Novel approach used while designing this module is the use of Bluetooth Protocol for transferring which has not been used as a transmitting medium in any of the projection related applications. Moreover this Invention involves a Universal module which acts like a portable connector which can be connected to any VGA projectors; this kind of connector module is not available at present anywhere in the market.
