Abstract

Virtual reality experiences can be made more immersive with the use of haptic technologies. However, the current methods rely on bulky controllers and gloves that only offer basic vibrations to differentiate textures. This thesis proposes a new approach that utilizes ultrasound haptics and various techniques to create a sense of roughness. The research conducted explores different parameters for inducing roughness and their compatibility with ultrasound haptics. A new technique for eliciting varying levels of roughness using basic patterns is also introduced. To compensate for the lack of physical object and textural information, two studies were conducted using audio and visual modalities. The findings reveal that basic patterns can successfully simulate roughness through ultrasound haptics, but some traditional roughness-inducing parameters do not work. Additionally, visuals have a minimal impact on roughness perception, and audio does not positively affect it.
