Patent ID: 8474976

Claim:
An automatic accommodative spectacle device for use by a user, comprising: a spectacle frame; one or more focusing elements mounted on the spectacle frame; one or more sensors located adjacent the one or more focusing elements for capturing signals about left and right eyes of the user; a line of sight detector coupled to the sensors for determining a line of sight for the left eye and a line of sight for the right eye of the user based on the signals captured by the sensors; a focus engine coupled to the line of sight detector for determining a fixation region of interest of the user by minimizing a distance between the lines of sight for the left and right eyes, and for determining optimum powers for the focusing elements based on the fixation region of interest; and a focusing elements controller connected to the focusing elements and the focus engine for controlling optical powers of the focusing elements based on the optimum powers for the focusing elements determined by the focus engine.
