A system of the present invention automatically controls electronic devices based
on physiological conditions of a user. In this regard, the system includes a sensor
and a controller. The sensor is positioned adjacent to an eye of a user and is
configured to detect a physiological response of the user. The sensor is configured
to transmit, in response to a detection of the physiological response, a signal
indicative of the response. The controller is configured to receive the signal
and to control an electronic device based on the signal.
