Texture Palette is a texture simulating solution for creating the physical experience of VR content. Hardware and software innovations of Texture Palette provide tactile interaction beyond the screen. We can feel the texture of digital objects in VR content, such as roughness, hardness, temperature and pattern. This is the next paradigm shift in VR interaction and allows us to interact with immersive and realistic VR experiences.

People combine tactile evidence when they touch. Chance factors are derived from human tactile perception experiments. When we interact tactilely with objects, we first sense their properties, such as roughness, temperature, pattern, and hardness. And we combine them to discern their texture. For example, if we touch a metal, we can feel its low temperature and smooth surface. Each material consists of more than one element, which is an opportunity to reproduce artificial textures.

Texture Palette modelled the five elements of texture based on previous experiments. Texture is categorised into roughness, temperature, hardness, pattern and sound. And it is re-formed by combining several elements. This allows the user to feel the specific texture of the artefact they are interacting with in the VR game. We can feel the grain of a sword hilt, the softness of human skin. In addition, it can represent objects in various environments such as snowy mountains and deserts through temperature control.
