Research on Extended Reality (XR) and Artificial Intelligence (AI) is booming, which has led
to an emerging body of literature in their intersection. However, the main topics in this …

Despite the potential of Virtual Reality as the next computing platform for general purposes,
current systems are tailored to stationary settings to support expansive interaction in mid-air …

When users wear a virtual reality (VR) headset, they lose access to their smartphone and
accompanying apps. Past work has proposed smartphones as enhanced VR controllers, but …

Abstract We study Congruent Indirect Touch (CIT) interaction in a desktop context. CIT only
differs from direct touch in that the motor and display spaces are separated: touch occurs on …

We present ShadowTouch, a novel sensing method to recognize the subtle hand-to-surface

In this study, we explore a new way to complementarily utilize the immersive visual output of
VR and the physical haptic input of a smartphone. In particular, we focus on interacting with …

We introduce VIREO, a web-based software tool for graphical authoring of vibrotactile
feedback for mobile and wearable applications. VIREO enables flexible specification of …

We present XDTK, an open-source Unity/Android toolkit for proto-ty** multi-device
interactions in extended reality (XR). With the Unity package and Android app provided in …
