HieraVisVR: Hierarchical Visual Analytics for Motion-Centric VR Playtesting

Playtesting is widely used in the game industry to identify design flaws and evaluate player experience, yet little research explores how to effectively visualize and analyze playtesting data. This challenge is particularly pronounced in motion-based VR games, which involve physical movements and interactions tracked…

Out of Control: Effects of Multimodal Self-similarity on Embodiment During Autonomous Avatar Demonstrations in Virtual Reality

Virtual reality (VR) training often requires autonomous avatar demonstrations, yet embodiment is strongest under direct control. We examine whether multimodal self-similarity (i.e., in appearance and voice) can preserve embodiment when control is constrained. In a 2 (self-similarity: self-similar vs. non-self-similar)…

Game-Based and Gamified Robotics Education: A Comparative Systematic Review and Design Guidelines

Robotics education fosters computational thinking, creativity, and problem-solving, but remains challenging due to technical complexity. Game-based learning (GBL) and gamification offer engagement benefits, yet their comparative impact remains unclear. We present the first PRISMA-aligned systematic review and comparat…

On the Intelligence and Knowledgeability of Virtual Agents

Intelligence and knowledgeability are sometimes treated interchangeably in virtual agents, yet they shape interaction in different ways. We disentangled these traits and tested how each drives human perceptions and interaction in virtual reality (VR). To address the lack of prior research examining both traits simulta…

Audio Matters Too: How Audial Avatar Customization Enhances Visual Avatar Customization

Avatar customization is known to positively affect crucial outcomes in numerous domains. However, it is unknown whether audial customization can confer the same benefits as visual customization. We conducted a preregistered 2 x 2 (visual choice vs. visual assignment x audial choice vs. audial assignment) study in a Ja…
