Gaze technology is enabling gamers to play without even counting on the keyboard, joystick, and similar stuff. It’s unbelievable, but true. As per the researchers at the UK's De Montfort University, it’s possible to play games with the help of eyes only. This gaze gaming allows gamers to carry out various commands that embrace moving avatar, change the angle of viewing, direct objects, and converse with other players. The guiding principle implies the tracking of a person's eye movements using hi-fi infrared cameras when they meet infrared light from LEDs at the bottom of a PC. Person’s eye movements can be tracked with an accuracy of about 5 mm. A 'gaze gesture' facilitates momentarily turning off of the eye-gaze functions all in all; thus, avoiding chance selection of an item. So, while technology is assisting the mankind to outdo any hang-up, it really is making them ever more lethargic; certainly, there is the other aspect, its usability to physically challenged individuals.
