We propose a see-through near-eye display, which is dedicated to the visually impaired users who suffer from refractive anomalies. Our solution is characterized by a pair of corrective lenses coated with multiplexed volume holograms. Its key performance including diffraction efficiency, field of view, modulation transfer function, and distortion has been studied.

Complementary and alternative medicine (CAM) is widely used by patients worldwide. Financial factors may influence the decision to use CAM. National Health Systems are requested to consider CAM in their health plans.

This paper discusses how eye tracking can be used to supplement usability testing and intends to identify best practice about eye tracking in its scientific and practical sense, especially as applied to commercial usability engineering practice.

In this paper, we present a novel method the étendue expansion of near-eye holographic displays through generation sparse eye-box. Conventional have suffered from narrow field view or eye-box due to limited supported by spatial light modulator. We focus on fact that these typically form dense eye-box, which could be an excessive investment étendue. By rearranging in manner, practical can extend...

Neurophysiological and behavioral reports converge to suggest that monocular neurons in the primary visual cortex are biased toward low spatial frequencies, while binocular neurons favor high spatial frequencies. Here we tested this hypothesis with functional magnetic resonance imaging (fMRI). Human participants viewed flickering gratings at one of two spatial frequencies presented to either th...
