Contact Lens with Moiré Patterns for High‐Precision Eye Tracking

Advanced Functional Materials, EarlyView.
This work presents a passive contact lens for high‐precision eye tracking, integrating a microscopic moiré grating label. The parallax‐induced shift of macroscopic moiré patterns enables angle measurement with 0.28° precision using a standard camera under ambient light.

Simulation Analysis of an ETC Monitoring and Imaging Supplementary Lighting Device for Freeways

Infrastructures
To address the glare issues caused by highway ETC gantry monitoring and imaging illumination devices, this paper first investigates the mechanism of disability glare and derives the formula for the glare threshold increment. Subsequently, using the glare

Degraded reality: Using VR/AR to simulate visual impairments [PDF]

, 2018
The effects of eye disease cannot be depicted accurately using traditional media. Consequently, public understanding of eye disease is often poor. We present a VR/AR system for simulating common visual impairments, including disability glare, spatial ...

Lithium Intercalation in the Anisotropic Van Der Waals Semiconductor CrSBr

Advanced Functional Materials, EarlyView.
We report the lithium intercalation in the layered van der Waals crystal CrSBr, revealing strongly anisotropic ion‐migration dynamics. Optical and electrical characterization of exfoliated CrSBr shows lithium diffusion coefficients that differ by more than an order of magnitude along a‐ and b‐directions, consistent with molecular dynamics simulations ...

Functional acuity contrast sensitivity assessment in young and middle age healthy persons at the day time with and without glare

Acta Medica Lituanica, 2014
Background. As people age, their vision becomes less clear; they can clearly see big objects but experience problems discerning minor things and minor details.

Trap‐Assisted Transport and Neuromorphic Plasticity in Lead‐Free 2D Perovskites PEA2SnI4

Advanced Functional Materials, EarlyView.
An artificial retina built from lead‐free layered perovskite (PEA)2SnI4 converts light input into a persistent photocurrent and sums successive flashes over time. Micro/nanocrystals integrated on electrodes act as synapse‐like pixels that perform temporal integration directly in hardware. This in‐sensor preprocessing merges detection and computation on

Daylight Glare with the Sun in the Field of View: An Evaluation of the Daylight Glare Metric Through a Laboratory Study Under an Artificial Sky Dome and an Extensive Simulation Study

Buildings
The Daylight Glare Probability (DGP) includes the luminance of a glare source quadratically, but the solid angle only linearly. While this is in line with formulae of other glare metrics, it must be questioned for small glare sources, if the glare ...

Improvement of mode-Ⅱ interface mechanical properties of Al/GFRP composite laminates by VGCF

Nihon Kikai Gakkai ronbunshu, 2014
Research and development on a composite material named as Fiber-Metal Laminates (FML) for its airplane structural applications have been focused on in recent years. These materials laminate FRP (Fiber Reinforced Plastic) of susceptibility to out-of-plane

Temporally Delayed Deployment of Photo‐Responsive Liquid Crystal Polymer Networks Toward Neural Interfaces

Advanced Healthcare Materials, EarlyView.
Deployable medical devices typically need external stimuli to trigger deployment. However, external stimuli are difficult to supply within tissues. Here, we describe a strategy to deploy small‐scale structures into soft tissues after insertion without the need for any stimulus. We demonstrate deployment within a tissue phantom.
