Abstract: Effective patient-centered care in a hospital relies heavily on the ability of patients to communicate their physical needs to care givers. If a patient is unable to speak, he has limited means of communicating at a time when he needs it the most. The embodiments presented here, generally referred to as EyeVoice, include unobtrusive eye-operated communication systems for locked-in hospital patients who cannot speak or gesture. EyeVoice provides an alternate means of communication, allowing hospital patients to communicate with their care givers using their eyes in place of their voices. Simply by looking at images and cells displayed on a computer screen placed in front of them, patients are able to: answer questions posed by caregivers; specify locations, types and degrees of pain and discomfort; request specific forms of assistance; ask or answer care related questions, and help direct his own care.
