JourneyVR: Designing for Continuous Workflow Experience in Virtual Reality

Managing multiple activities in virtual reality (VR) is often hindered by fragmented workflows and disruptive application switching. We present JourneyVR, a metaphorical interaction model designed for spatial and sequential workflows that reframes tasks as continuous journeys rather than isolated sessions. Users const…

Quantifying Low-Level Motor Effects of Emotion: Validating Fitts’ Law in Affective Contexts

Emotional states influence a wide range of cognitive processes, such as attention, memory, and decision-making, and play an increasingly recognized role in human-computer interaction (HCI). Although most prior research has focused on high-level effects of emotion, the impact of incidental emotional states on fine-grai…

The Impact of Observer Presence on Trainees' Mental States and Performance in Remote Military Training with Virtual Humans in Mixed Reality Environment

Remote, vs. in situ, instruction may be regarded to decrease trainee engagement and concentration, potentially reducing training effectiveness. As such, local evaluative observers are often deployed to create the situated atmosphere. However, these observers can also have a negative effect on the trainees' mental stat…

The Effects of False but Stable Heart Rate Feedback on Cybersickness and User Experience in Virtual Reality

Virtual reality (VR) offers a compelling and immersive experience; however, cybersickness (or VR sickness) stands as a significant obstacle to its widespread adoption. When a user experiences cybersickness, one's physical condition deteriorates with various symptoms, often accompanied by an increased and destabilize…

Engaged and Affective Virtual Agents: Their Impact on Social Presence, Trustworthiness, and Decision-Making in the Group Discussion

This study investigates how different virtual agent (VA) behaviors influence subjects' perceptions and group decision-making. Participants carried out experimental group discussions with a VA exhibiting varying levels of engagement and affective behavior. Engagement refers to the VA's focus on the group task, wher…

Mixing in Reverse Optical Flow to Mitigate Vection and Simulation Sickness in Virtual Reality

Simulator sickness has been one of the major obstacles toward making virtual reality (VR) widely accepted and used. For example, virtual navigation produces vection, which is the illusion of self-motion as one perceives bodily motion despite no movement actually occurs. This, in turn, causes a sensory conflict betw…
