EyePhone is a system that allows users to control mobile applications using only their eyes and eye movements like winking (Summary 1).
Human-phone interaction (HPI) presents new challenges for human-computer interaction (HCI) due to issues of mobility, the phone's form factor, and its limited resources. HPI differs from traditional HCI in its focus on mobility and the lack of specialized hardware. (Summary 2).
HPI technology should be less intrusive by not relying on external devices, being readily usable with minimal user input, fast inference, lightweight computation, and preserving normal phone usage and battery life. (Summary 3).
