About

Alexa Siu is a leading researcher in human-computer interaction, specializing in shape-changing interfaces and tangible interaction. Her most impactful work centers on the development of **shapeShift**, a compact, high-resolution (7 mm pitch) mobile tabletop shape display that redefines how users physically engage with digital content. Siu’s major contribution lies in exploring both passive and active self-actuation—enabling bimanual 2D spatial manipulation where users can freely move, spin, and interact with a dynamic surface that renders elements in real time. This innovation bridges the gap between virtual and physical worlds, allowing for intuitive, hands-on data exploration and collaborative tasks. Her 2018 paper on shapeShift has garnered **134 citations**, reflecting its influence on subsequent research in actuated interfaces and haptic feedback. By demonstrating novel interaction techniques for mobile shape displays, Siu has opened new avenues for accessible, embodied computing. Her work is essential reading for students and researchers interested in the future of tangible user interfaces, dynamic physical visualizations, and the seamless integration of computation into our everyday environments.
