This paper investigates how visual texture presentation influences tactile perception when interacting with electrostatic cloth displays. We propose a visuo-haptic system that allows users to pinch and rub virtual fabrics while feeling realistic frictional sensations modulated by electrostatic actuation. Through a user study, we examined the cross-modal effects between visual roughness and perceived tactile friction. The results demonstrate that visually rough textures amplify the perceived frictional force, even under identical electrostatic stimuli. These findings contribute to the understanding of multimodal texture perception and provide design insights for haptic feedback in virtual material interfaces.

Occlusion is a crucial visual element in optical see-through (OST) augmented reality, however, implementing occlusion in OST displays while addressing various design trade-offs is a difficult problem. In contrast to the traditional method of using spatial light modulators (SLMs) for the occlusion mask, using photochromic materials as occlusion masks can effectively eliminate diffraction artifacts in see-through views due to the lack of electronic pixels, thus providing superior see-through image quality. However, this design requires UV illumination to activate the photochromic mate-rial, which traditionally requires multiple SLMs, resulting in a larger form factor for the system. This paper presents a compact photochromic occlusion-capable OST design using multilayer, wavelength-dependent holographic optical lenses (HOLs). Our approach employs a single digital mi-cromirror display (DMD) to form both the occlusion mask with UV light and a virtual image with visible light in a time-multiplexed man-ner. We demonstrate our proof-of-concept system on a bench-top setup and assess the appearance and contrasts of the displayed image. We also suggest potential improvements for current prototypes to encourage the community to explore this occlusion approach.
