Ayman Alzayat is a PhD Candidate in the Department of Management Sciences supervised by Mark Hancock at the University of Waterloo and Miguel Nacenta at University of St Andrews.

His focus is on understanding touch experience, particularly, how people experience physical and virtual objects. He has been involved in the design and implementation of several projects that helps understand touch in the field of HCI. He also, works on bringing psychological theories to the virtual and digital world to observe touch experience implications.

Ayman did his Masters at University of Waterloo in in the Department of Management Sciences. His thesis work looked at how people learn from stories and how each story can either help or hinder people’s cognitive learning to solve a particular problem.

  • A. Alzayat, M. Hancock, and M. Nacenta, Quantitative Measurement of Virtual vs. Physical Object Embodiment Through Kinesthetic Figural After Effects, in Proc. CHI, New York, NY, USA, 2014, pp. 2903-2912.

    Over the past decade, multi-touch surfaces have become commonplace, with many researchers and practitioners describing the benefits of their natural, physical-like interactions. We present a pair of studies that empirically investigates the psychophysical effects of direct interaction with both physical and virtual artefacts. We use the phenomenon of Kinesthetic Figural After Effects-a change in understanding of the physical size of an object after a period of exposure to an object of different size. Our studies show that, while this effect is robustly reproducible when using physical artefacts, this same effect does not manifest when manipulating virtual artefacts on a direct, multi-touch tabletop display. We contribute quantitative evidence suggesting a psychophysical difference in our response to physical vs. virtual objects, and discuss future research directions to explore measurable phenomena to evaluate the presence of physical-like changes from virtual on-screen objects.
