Spatial augmented reality (SAR) pursues realism in rendering materials and objects. To advance this goal, we propose a hybrid SAR (HySAR) that combines projector with optical see-through head-mounted displays (OST-HMD). In an ordinary scenario co-located viewers, the viewers perceive same virtual material on physical surfaces. general, consists of two components: view-independent (VI) component such as diffuse reflection, view-dependent (VD) specular reflection. The VI is static over...

Brightness adaptation is a fundamental ability in human visual system, and adjusts various levels of darkness light. While this continuously used, it can mostly handle sudden lighting changes the environment, could still take several minutes. Moreover, during adaptation, color perception as well. This slow reactivity change eyes lead to mistakes for tasks performed dazzling or temporally high-contrast environments such when driving into sun welding process.

Occlusion is a crucial visual element in optical see-through (OST) augmented reality, however, implementing occlusion OST displays while addressing various design trade-offs difficult problem. In contrast to the traditional method of using spatial light modulators (SLMs) for mask, photochromic materials as masks can effectively eliminate diffraction artifacts views due lack electronic pixels, thus providing superior image quality. However, this requires UV illumination activate mate-rial,...

The tactile sensation of textiles is critical in determining the comfort clothing. For remote use, such as online shopping, users cannot physically touch textile clothes, making it difficult to evaluate its sensation. Tactile sensing and actuation devices are required transmit textiles. device needs recognize different garments, even with hand-held sensors. In addition, existing can only present a limited number known patterns unknown sensations To address these issues, we propose...

We present StainedView, an optical see-through display that spatially filters the spectral distribution of light to form image with improved color fidelity. Existing light-attenuation displays have limited fidelity and contrast, resulting in a degraded appearance virtual images. To use these images are more consistent real world, we require three things: intensity modulation incoming light, spatial filtering narrower bandwidth, appropriate for arbitrary distribution. In address requirements...
