Event Description:
"Designing Motion Gestures for Mobile Interaction"
Jaime Ruiz
Colorado State University

ECCR 265
Thursday, April 18
3:30-4:30 PM

ABSTRACT: Hand motion -- pointing, gesturing, grasping, shaking, tapping -- is a rich channel of communication. We point and gesture while we talk; we grasp tools to extend our capabilities; we grasp, rotate, and shake items to explore them. Yet, the rich repertoire of hand motion is largely ignored in interfaces to mobile computation: the user of a modern smartphone generally holds the device stationary while tapping or swiping its surface. Why are so many possible affordances ignored? Certainly not for technical reasons, as smartphones contain an evolving set of sensors for recognizing movement of the phone, including accelerometers, gyroscopes and cameras. However, beyond rotating to change screen orientation or shaking to shuffle songs, little has been done to enable rich gestural input through device motion. In this talk, I will explore our on-going work in the design and implementation of motion gestures to control modern smartphones. I will present the results of an elicitation study that we conducted that demonstrates that consensus exists among a group of prospective end-users on parameters of movement and on mappings of motion gestures onto commands. I will show how we have used this consensus to develop a taxonomy for motion gestures. Finally, I will discuss grand research challenges with using motion gestures as an input modality for mobile interaction.

BIO: Dr. Jaime Ruiz is an Assistant Professor in the Computer Science Department at Colorado State University. He received his Ph.D. in Computer Science from University of Waterloo in 2012, and was as a research intern at Palo Alto Research Center (PARC) and Google Research. His research in Human-Computer Interaction explores leveraging human perception and performance to support end-user interaction, and the examination of alternative interaction techniques for mobile interaction. Dr. Ruiz is a recent recipient of a Google Faculty Research Award.
