About

Yuan-Chia Chang is a researcher at the intersection of human-computer interaction, virtual reality, and social robotics, with a focus on how technology can shape perception, behavior, and authority. His work spans two compelling domains: haptic guidance systems and the design of authoritative social robots. In his most-cited paper, "GuideBand: Intuitive 3D Multilevel Force Guidance on a Wristband in Virtual Reality" (2021, 24 citations), Chang introduced a novel approach to vibrotactile feedback that reduces users' cognitive load during 3D navigation in VR, offering a more intuitive alternative to complex haptic patterns. This contribution addresses a fundamental challenge in immersive interaction. More recently, Chang has turned to the social implications of robotics. In "Investigating the Impact of Gender Stereotypes in Authority on Avatar Robots" (2024, 8 citations), he explores how ingrained gender biases influence operator and interlocutor perceptions, revealing critical design considerations for equitable human-robot interaction. His 2025 work, "Designing Authoritative Presence in Social Robots," further defines and operationalizes the concept of "authoritative presence," demonstrating how robots can be designed to elicit respect and compliance without coercion. Chang’s research is notable for bridging technical innovation with ethical and psychological dimensions, offering practical insights for creating more intuitive and socially aware interactive systems.
