1. A system comprising:
- a housing;
an interrogation signal source housed in the housing and adapted for delivering an interrogation signal to an eye of a subject, the interrogation signal source including at least one light source and at least one optical system;
a response signal sensor housed within the housing and adapted for sensing a response signal produced by the eye of the subject responsive to the interrogation signal, the response signal containing information regarding a physiological parameter of the subject;
an output structure adapted for transmitting an output signal; and
mounting means adapted for mounting the housing with respect to a display in such a manner that the interrogation signal source and response signal sensor are alignable with the eye of the subject during normal use of the display by the subject.

Abstract
Methods and systems for determining a physiological parameter of a subject through interrogation of an eye of the subject with an optical signal are described. Interrogation is performed unobtrusively. The physiological parameter is determined from a signal sensed from the eye of a subject when the eye of the subject is properly aligned with regard to an interrogation signal source and/or response signal sensor.
