Abstract

Several embodiments of a personal display system are disclosed that comprises modular and extensible features to affect a range of user/wearer/viewer experiences. In one embodiment, the personal display system comprises a frame; a processor capable of sending image data signals and control signals; a display; an optic system, said optic system optically coupled to said at least one display; and a set of actuators, said actuators coupled to said frame and in communication with the optic system, such that said set of actuators are capable of moving the optic system, according to control signals sent from said processor. In another embodiment, a method for pre-warping input image data under processor control and according to ambient conditions, such as light and temperature, is disclosed.
