Designing an intelligent blink analyzer tool for effective human computer interaction through eye

The traditional human-computer interfaces demand good manual agility and refined motor control, which may be absent or unpredictable for people with certain disabilities. Here it is proposed a robust, accurate algorithm with relevant hardware setup to detect eyes and measure the duration of blinks to interpret them in real time to control a computer or computer interfaced devices. The complete system is divided into two primary modules. The first one is to detect voluntary eye blink and second module to trigger an onscreen soft agent that interprets the blink into proper mouse movement with associated mouse action sequence. This is a low cost proposal and prototypes designed to work with web camera interfaced to a standard PC.
