When designing extended reality (XR) applications, it is important to consider multimodal
interaction techniques, which employ several human senses simultaneously. Multimodal …

Ultrasound haptics is a contactless haptic technology that enables novel mid-air interactions
with rich multisensory feedback. This article surveys recent advances in ultrasound haptic …

We present a method for creating three-dimensional haptic shapes in mid-air using focused
ultrasound. This approach applies the principles of acoustic radiation force, whereby the non …

This paper introduces Tacttoo, a feel-through interface for electro-tactile output on the user's
skin. Integrated in a temporary tattoo with a thin and conformal form factor, it can be applied …

Freehand gesture is an essential input modality for modern Augmented Reality (AR) user
experiences. However, developing AR applications with customized hand interactions …

Quadcopters have been used as hovering encountered-type haptic devices in virtual reality.
We suggest that quadcopters can facilitate rich haptic interactions beyond force feedback by …

Today's consumer virtual reality (VR) systems offer limited haptic feedback via vibration
motors in handheld controllers. Rendering haptics to other parts of the body is an open …

We present HaptoMime, a mid-air interaction system that allows users to touch a floating
virtual screen with hands-free tactile feedback. Floating images formed by tailored light …

Touch is a powerful vehicle for communication between humans. The way we touch (how)
embraces and mediates certain emotions such as anger, joy, fear, or love. While this …

We propose a nail-mounted foldable haptic device that provides tactile feedback to mixed
reality (MR) environments by pressing against the user's fingerpad when a user touches a …
