SUMMARY:AirRacket: Perceptual Design of Ungrounded, Directional Force Feed
 back to Improve Virtual Racket Sports Experiences
DESCRIPTION:Talks\n\nAirRacket: Perceptual Design of Ungrounded, Direction
 al Force Feedback to Improve Virtual Racket Sports Experiences\n\nCheng\n\
 nWe present AirRacket, perceptual modeling and design of ungrounded, direc
 tional force feedback for virtual racket sports. Using compressed air prop
 ulsion jets to provide directional impact forces, we iteratively designed 
 for three popular sports that span a wide range of force magnitudes: ping-
 pong, badminton, and tennis. To address the limited force magnitude of ung
 rounded force feedback technologies, we conducted a perception study which
  discovered the novel illusion that users perceive larger impact force mag
 nitudes with longer impact duration, by an average factor of 2.57x. Throug
 h a series of formative, perceptual, and user experience studies with a co
 mbined total of 72 unique participants, we explored several perceptual des
 igns using force magnitude scaling and duration scaling methods to expand 
 the dynamic range of perceived force magnitude. Our user experience evalua
 tion showed that perceptual designs can significantly improve realism and 
 preference vs. physics-based designs for ungrounded force feedback systems
