Article Abstract
A compact near-eye visor (NEV) system that can guide light from a display to the eye could transform augmented reality (AR) technology. Unfortunately, existing implementations of such an NEV either suffer from small field of view or chromatic aberrations. See-through quality and bulkiness further make the overall performance of the visors unsuitable for a seamless user experience. Metasurfaces are an emerging class of nanophotonic elements that can dramatically reduce the size of optical elements while enhancing functionality. In this paper, we present a design of composite metasurfaces for an ultracompact NEV. We simulate the performance of a proof-of-principle visor corrected for chromatic aberrations while providing a large display field of view (>77 both horizontally and vertically) and good see-through quality [>70 transmission and less than a wavelength root mean-square (RMS) wavefront error over the whole visible wavelength range] as needed for an immersive AR experience.

Aim: To evaluate the effectiveness of the CARES-MFW (Clinical Augmented Reality Education Simulation for Malignant Fungating Wounds) app in enhancing nurses' knowledge and clinical reasoning in the care of MFWs.
Background: Malignant fungating wounds (MFWs) affect many patients with advanced cancer, with nearly 50 % dying within six months of diagnosis. These wounds often present with heavy exudate, pain, malodor and bleeding, leading to profound physical and psychosocial distress.
ObjectiveThis work examined performance costs for a spatial integration task when two sources of information were presented at increasing eccentricities with an augmented-reality (AR) head-mounted display (HMD).BackgroundSeveral studies have noted that different types of tasks have varying costs associated with the spatial proximity of information that requires mental integration. Additionally, prior work has found a relatively negligible role of head movements associated with performance costs.

Augmented reality (AR) integrates virtual objects in the real world, allowing users to interact intuitively with navigation information. This study systematically reviewed 13 articles on AR technology published from 2005 to 2024 through meta-analysis, comprising a total of 400 participants, to examine its effectiveness in enhancing navigation performance. Compared with traditional navigation tools, the results showed that AR technology more effectively enhances navigation performance, with the overall effect size calculated as 0.
