Multi(Touch) Gesture Research Lecture: Journal Club – spring 2010 Florian Weil University of Art Linz – Master: Interface Culture
Questions● Which differences exist in gesture interaction on different screen sizes?● How is the research community for gesture interaction organized? ● Which conferences exist? ● Who are the key researcher and other important researcher?

Small Screen Gesture with Thumb● http://www.youtube.com/watch?v=bfH0-OqgbLw● Context: during movement, one hand interaction● Categories: Drag, Swipe, Rubbing, MicroRolls● Testings (10 people, Aged 23-28) ● MicroRoll 2x faster than contex menu UI ● MicroRoll same as fast as easy Toolbar, faster than difficult toolbar● MicroRoll Gesture itself: ● Robust and easy to learn ● Good perfomance (influenced by the position of the gesture) ● Good combination with TapTap, TapRoll, RollMark gestures
Medium screen: uni or bimanual gesture● Context: TableTop systems and Medium Screens● Motivation: investigate perfomance and the right task for uni and bimanual gestures● Approach: Testing the commands align, positioning, rotation, scaling of digital objects.● Result: ● Unimanual interaction for visual rotation, transporting, rotating, and stretching ● Bimanual interaction for control of two individual (control) points (example tasks: window manipulation, image croping etc.) ● Perfomance differences are small, so the designer can safely interchange between the two methods
TableTop Screen: Hand Distinction● Context: TableTop systems and Large Screens● Motivation: Distinguish one-hand and two-hand gestures improves gesture systems ● more stable and accurated gesture recognition ● avoiding of conflicts in multi-user systems● Approach: use the anatomy information of the user hand and combine them with touch point and finger orientation data.● Result: ● Average: 96% successfully hand recognition ● Thumb need a more detail observation ● Heuristic formular works fine, but constant values needs improvements

Large Screen Gesture via Pointing● http://www.youtube.com/watch?v=cV60gwiM5HM● Context: Big static screen, some objects are not reachable● Categories: Pointing and Touch gestures● Seamlessly direct object manipulation with pointing and touch● User test results: ● User think it is a very useful extension ● Very intuitiv and easy learning interaction ● Objects are easier to reach and less exhausting compared to touch-only systems ● User did not really use these two interactions for the same task
