APPARATUS CONNECTABLE TO GLASSES

An apparatus connectable to a pair of glasses provides information to a user by processing images captured from the environment of the user. In one embodiment, the apparatus includes a support configured for mounting on the pair of glasses and a sensory unit. The sensory unit includes a housing configured for selective attachment to the support and an image sensor contained within the housing. The support and the housing are configured to enable selective aiming of the image sensor to establish a set aiming direction relative to the pair of glasses. The support and the housing are configured to cooperate with each other such that each time the sensory unit is attached to the support, the image sensor assumes the set aiming direction without need for directional calibration.
