In one embodiment, the first switchable lenticular device 110a can be relative to the primary optic axis 60a of first eye It is located in predetermined position or orientation, and the second switchable lenticular device 110b or recognizable magnetic field 50b or axis field source 150b Magnetic pole can be positioned relative to the second optical axis 60b of the second eyes with scheduled pitch angle α.In general, commanded pitch attitude can be Any suitable angle can change between an embodiment and next embodiment.For example, pitch angle α can be phase For non-parallel angle, obtuse angle or the acute angle of the first or second optical axis 60a, 60b.In addition, as described in more detail below, pitching Angle can be 0 °, so that can recognize that the magnetic-field component of magnetic field 50b is arranged essentially parallel to the second optical axis 60b.

In addition, identifiable magnetic field 50b may be oriented such that the first field sensor 140a or controller 130a can be with It distinguishes tilted (in-tilt) of eyes or assembles (for example, changing into focusing when subject attempts to focus on the first object In second object closer from subject) it tilts with the common of eyes (for example, when subject tilts or pivots eyes to focus Be located at periphery object, such as subject left or right side when).For example, identifiable magnetic field 50b can be relative to second Optical axis 60b with about 45 ° of positioning (for example, in the range of 1 ° smaller than 45 °, in the range of 2 ° smaller than 45 °, 5 ° of range smaller than 45 ° It is interior).

It should be appreciated that can recognize that magnetic field 50b can have any suitable orientation relative to the second optical axis 60b.For example, It can recognize that magnetic field 50b can be positioned relative to the second optical axis 60b, so that the convergence of eyes causes magnetic vector (for example, Lorentz Force vector) increase amplitude or change direction, this can with when eyes tilt jointly by the first field sensor 140a sense The direction of magnetic vector distinguish, discuss in greater detail below.In other words, it can recognize that magnetic field 50b can be positioned At to be handled by controller 130a from the received detection output of the first field sensor 140a, so as to so that controller 130a can distinguish the convergence of eyes or the Lorentz that can recognize magnetic field 50b is distinguished or identified to tilted and common inclined mode The amplitude of force vector or the variation in direction.

It is also understood that the first field sensor 140a of the first switchable lenticular device 110a can be configured as measurement magnetic The intensity of field and direction, to measure the magnetic-field component on particular sensitivity direction, or including multiple (juxtaposition or non-juxtaposition) magnetic Sensor, each magnetic sensor configuration at independent measurement magnetic field directional component.In one embodiment, the first field sensor 140a includes the sensor for being configured as measuring the magnetic-field component that 0 ° is oriented in relative to primary optic axis 60a.
