ABSTRACT
We describe Barehands, a free-handed interaction technique, in which the user can control the invocation of system commands and tools on a touch screen by touching it with distinct hand postures. Using behind-screen infrared (IR) illumination and a video camera with an IR filter, we enable a back-projected SMARTBoard (a commercially available, 61 3/8" x 47" touch-sensing display) to identify and respond to several distinct hand postures. Barehands provides a natural, quick, implement-free method of interacting with large, wall-mounted interactive surfaces.

Investigation of smartwatch touch behavior with different postures
MUM '17: Proceedings of the 16th International Conference on Mobile and Ubiquitous MultimediaThis paper investigates smartwatch touch behaviors of users with different hand postures by conducting a laboratory experiment with 12 participants and analyzing their tap events on a smartwatch with four postures: the no-support (NS) posture, thumb ...
A study on touch & hover based interaction for zooming
CHI EA '12: CHI '12 Extended Abstracts on Human Factors in Computing SystemsProximity is a useful medium for interaction with high interactive digital contents. It can be used in different contexts such as for navigation through depth in 3D space in zoomable interfaces. In this paper, we propose hover-based zoom interaction as ...
Bezel swipe: conflict-free scrolling and multiple selection on mobile touch screen devices
CHI '09: Proceedings of the SIGCHI Conference on Human Factors in Computing SystemsZooming user interfaces are increasingly popular on mobile devices with touch screens. Swiping and pinching finger gestures anywhere on the screen manipulate the displayed portion of a page, and taps open objects within the page. This makes navigation ...
