Walking Through or Detour? Investigating Walking Paths with World‑Anchored Mixed Reality Objects

In mixed reality environments, virtual objects can obscure real-world obstacles, creating a risk of collision when users walk through them. Although users may choose to detour around virtual objects, this behavior also carries risks, such as colliding with obstacles or pedestrians along the detour route. To reduce col…

HoloBots: Augmenting Holographic Telepresence with Mobile Robots for Tangible Remote Collaboration in Mixed Reality

This paper introduces HoloBots, a mixed reality remote collaboration system that augments holographic telepresence with synchronized mobile robots. Beyond existing mixed reality telepresence, HoloBots lets remote users not only be visually and spatially present, but also \textit{physically} engage with local users a…

Designing with Gaze: Tama, a Gaze Activated Smart-Speaker

Recent developments in gaze tracking present new opportunities for social computing. This paper presents a study of Tama, a gaze actuated smart speaker. Tama was designed taking advantage of research on gaze in conversation. Rather than being activated with a wake word (such as ``Ok Google'') Tama detects the gaze of…

Effect of Manipulated Amplitude and Frequency of Human Voice on Dominance and Persuasiveness in Audio Conferences

We propose to artificially manipulate participants' vocal cues, amplitude and frequency, in real time to adjust their dominance and persuasiveness during audio conferences. We implemented a prototype system and conducted two experiments. The first experiment investigated the effect of vocal cue manipulation on the per…
