Advanced Science, EarlyView.We present a large‐area bidirectional human–machine interface integrating electrostatic multimodal tactile sensing with a dual‐resonant haptic actuator. The system enables linear pressure sensing that is decoupled from actuation and stable broadband vibrotactile feedback under dynamic contact conditions, supporting real‐time feedback modulation aligned

Retina‐Inspired Bi‐Based Terahertz Photonic Neuromorphic Devices
Advanced Science, EarlyView.Combined with effective band alignment and substrate engineering, bismuth materials are introduced to form terahertz photonic bio‐inspired devices with picosecond short‐term plasticity to enable multi‐scene visual perception. Thus obtained hardware through the terahertz optical neural network (THz‐ONN) demonstrates high recognition accuracy, providing ...

Shadow‐Calibrated Stereo Vision for Colorimetric Sweat Analysis
Advanced Science, EarlyView.By establishing a mathematical model that reconstructs 3D structures through geometric features of object shadows under controlled illumination, and combining it with Convolutional Neural Network‐based 2D image analysis for volumetric calibration, this work enables highly accurate 3D morphological reconstruction.

Developmental color perception
Journal of Experimental Child Psychology, 1975Abstract The purpose of this research is to extend the investigation of surface color perception to several age levels. The 108-item color perception test, originally used with young children, employs six Munsell hue matrices divided into nine combinations each of low, mid, and high chroma and low, mid, and high value across two levels of hue ...

Twelve SCUBA divers were assigned in groups of four to depths of 30, 60, and 90 ft. in the ocean to examine 13 plates of a standard diagnostic color perception test. In clear water, under conditions of low illumination, colors in the full range of the visible spectrum were detectable at 90 ft.

Scholars are increasingly employing skin color measures to investigate racial stratification beyond the dimensions of self- or other-classification. Current understandings of the relationship between phenotypic traits, like skin color, and racial classification are incomplete.

To understand the physics of color, one must first understand the basics of color perception. Color is, first and foremost, a perception. Even though the stimulus that enters our eyes and produces the perception can be described and measured in physical terms, the actual color that we perceive is the result of a complex series of processes in the human

Human infants 4 to 6 months of age devoted more visual fixation to checkerboards composed of two Munsell hues equated for brightness and saturation than to unpatterned targets of either hue. Strength of pattern preference was positively related to degree of hue difference in the checkerboards.
