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 according to a schedule, under the control of a scheduling controller.

398. A system for sensing information from an eye of a subject, comprising:
-
an interrogation signal source for delivering an interrogation signal to the eye of the subject; a response signal sensor for sensing a response signal produced by the eye of the subject responsive to the interrogation signal; a gaze attractor adapted to attract the gaze of the subject to thereby cause the eye of the subject to move into alignment with at least one of the interrogation signal source and the response signal sensor; and signal processing circuitry including; a response signal processor configured to process a response signal sensed from the eye of the subject when the eye of the subject is in alignment with respect to the at least one of the interrogation signal source and the response signal sensor to determine a physiological parameter from the response signal; and an data transmission structure adapted to output a signal relating to the determined physiological parameter. - View Dependent Claims (399, 400, 401, 402, 403, 404)

405. 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; a gaze attractor adapted to attract the gaze of the subject to thereby cause the eye of the subject to move into alignment with at least one of the interrogation signal source and the response signal sensor; 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. - View Dependent Claims (406, 407, 408, 409, 410, 411, 412, 413, 414, 415, 416, 417, 418)

419. A method of measuring information from an eye of a subject, comprising;
-
delivering an interrogation signal to the eye of the subject with an interrogation signal source; detecting a response signal from the eye of the subject with a response signal sensor, wherein the interrogation signal is reflected from a region or structure within the eye of the subject to form the response signal; controlling a gaze attractor to cause the eye of the subject to move into alignment with at least one of the interrogation signal source and the response signal sensor; determining a physiological parameter of the subject from the response signal detected from the eye of the subject when the eye of the subject is in alignment with respect to the at least one of the interrogation signal source and the response signal sensor, wherein the physiological parameter includes a measurement of at least one of a substance in the blood of the subject, a substance in an aqueous humor of the subject, oxygen, glucose, a salt, a protein, a lipid, a gas, a hormone, a drug, a pulse rate, a blood flow, and a temperature; and transmitting at least one of information regarding the subject, information regarding a method used for determining the physiological parameter, or information regarding the physiological parameter to a data processing system. - View Dependent Claims (420, 421, 422, 423, 424, 425, 426, 427, 428, 429, 430, 431, 432, 433, 434, 435, 436, 437, 438, 439)
