Electronic Safety Assistance for Blind using micro controller and DSP voice processor
The Project aims at Providing Assistance for the Blind People against obstructions. The Blind People has to wear the equipment; the equipment transmits IR Communication Code into the Free Space. The reflected IR Communication Code received by the Same Micro-controller. The reflection takes place only any obstruction near by the device. If the code is similar to the transmitted code the obstruction is confirmed & it gives a voice response at the equipment.
The equipment is constructed with popular Micro-Controller MCS51 Series, 89C52 & IR Transmitters, Receivers etc. We have implemented bi-directional protocol for IR Transmissions & Receptions via Serial Port available with the Micro-Controller.
