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.

Variable-addressability electronic binocular system.

The eye's acuity varies across its field of view (FOV), decreasing to 10% of its axial value at only 20 degrees. We describe an optical system that radially remaps the pixels of a miniature display or sensor to match the varying acuity of the eye across its FOV. The variable-acuity technique increases the FOV of an electronic binocular system without any apparent loss in image quality. The result is a better, more efficient human-machine interface.
