An Approach to design Keyboard and Mouse assisting device for handicap users

The main idea is to develop an intelligent computing system for disabled people, especially handicapped people who are willing to use a computer for their usage purpose. Still, due to their disability, they can't use it. Nowadays, engineers try to make some equipment to solve this problem because this century is the computer century. The usage of the computer nowadays is very important. A person needs to use computers for their office purpose, education, and communication. A normal person can do this easily, but a disabled person, especially handicapped people, can't do this. This is a hard situation for a handy cap person because He also needs to communicate with the world. The proposed design can help handicapped peoples use computers for their usage purpose. Intelligent Computing System (ICS) is based on two units one is a head unit which contains a LASER which is used as a remote control, the other unit is ground unit which contains LDR sensor-based keyboard, controlling circuits may assets in performing the whole functionality of the ICS system by providing the instructions through the coding directed by PIC Controller which sending the data to the computer through MAX233 IC. The proposed LDR-based-matrix keyboard system sensor was sensitive enough to detect laser light which was tested on ten different users and shown promising accuracy; for future enhancement in order to use this device as a commercial device, instead of LDR matrix, we can, or the fabrication industry can fabricate LDR matrix during the fabrication process, to minimize the size of the system in order to save the power consumption of the system and may also allow a handicap people to use a computer and communicate with the world and gain knowledge and information just like a normal people.
