Evaluation of a variable-addressability monocular

A variable-addressability monocular that provides a variation in resolution across the field of view is presented. The variation in resolution is based on the eye's visual-acuity curve. A prototype has been built that does a nonlinear mapping of the pixels, designed to work most efficiently with the human visual system. In addition a conventional, uniform-addressability prototype has been built. A human-factors experiment is presented that directly compares the variable-addressability prototype with the conventional system. The human-factors results show that the variable-addressability prototype provides better resolution 13% of the time but is 15% slower in use than the uniform-addressability prototype.
