In order to address these goals HPI technology should be less intrusive; that is, i) it should not rely on any external devices other than the mobile phone itself; ii) it should be readily usable with minimum user dependency as possible; iii) it should be fast in the inference phase; iv) it should be lightweight in terms of computation; v) it should preserve the phone user experience, e.g., it should not deplete the phone battery over normal operations.

Eye Phone – Controlling Phone by Eyes Terminologies Intrusive Method: which requires direct contact with the eyes Non- Intrusive methods: which avoid any physical contact with the user Model based method Appearance based method Feature based method Paper Abstract EyePhone tracks the user’s eye movement across the phone’s display using the camera mounted on the front of the phone i) Track the eye and infer its position on the mobile phone display as a user views a particular application ii) Detect eye blinks that emulate mouse clicks to activate the target application under view. EyePhone Design 1) An eye detection phase 2) An open eye template creation phase 3) An eye tracking phase 4) A blink detection phase Eye detection phase By applying a motion analysis technique which operates on consecutive frames, this phase consists on finding the contour of...
