Fast and reliable prediction of noncoding RNAs

by Stefan Washietl, Ivo L. Hofacker, Peter F. Stadler - Proc Natl Acad Sci USA
"... We report an efficient method to detect functional RNAs. The approach, which combines comparative sequence analysis and structure prediction, yields excellent results already for a small number of aligned sequences and is suitable for large scale-genomic screens. It consists of two basic components: ..."

Precise selection techniques for multi-touch screens

by Hrvoje Benko - Proceedings of CHI ’06 , 2006
"... The size of human fingers and the lack of sensing precision can make precise touch screen interactions difficult. We present a set of five techniques, called Dual Finger Selections, which leverage the recent development of multitouch sensitive displays to help users select very small targets. These ..."

Haptic Pen: A Tactile Feedback Stylus for Touch Screens

by Johnny C. Lee, Paul H. Dietz, Darren Leigh, William S. Yerazunis, Scott E. Hudson, Johnny C. Lee, Paul H. Dietz, Darren Leigh, William S. Yerazunis, Scott E. Hudson - Proceedings of the 17th Annual ACM Symposium on User Interface Software and Technology (UIST), ISBN , 2004
"... In this paper we present a system for providing tactile feedback for stylus-based touch-screen displays. The Haptic Pen is a simple low-cost device that provides individualized tactile feedback for multiple simultaneous users and can operate on large touch screens as well as ordinary surfaces. A pre ..."

Shift: a technique for operating pen-based interfaces using touch

by Daniel Vogel, Patrick Baudisch - PROC. CHI '07 , 2007
"... Retrieving the stylus of a pen-based device takes time and requires a second hand. Especially for short intermittent interactions many users therefore choose to use their bare fingers. Although convenient, this increases targeting times and error rates. We argue that the main reasons are the occlusi ..."

techniques, Shift is only invoked when necessary—over large targets no callout is created and users enjoy the full performance of an unaltered touch screen. We report the results of a user study showing that with Shift participants can select small targets with much lower error rates than an unaided touch

Audiotactile Feedback for Touch Screens

by Sebastian Merchel, Ercan Altinsoy
"... Touch sensitive displays and touch surfaces are more and more replacing physical buttons. If a physical button is pressed, audio and tactile feedback confirms the successful operation. The loss of audiotactile feedback ..."

eCell - Spatial IT Design for Group Collaboration and Learning in School Environments

by Christina Brodersen, Ole Sejer Iversen - In Schmidt, Pendergast, Ackermann & Mark (Eds.) Proceedings of the International ACM SIGGROUP Conference on Supporting Group Work , 2005
"... In this paper we present the eCell; a temporary, collaborative niche for group work in school environments. The eCell consists of a private inner display and a public outer display located in unused public spaces e.g. in corridors and libraries throughout the school premises. The inner display is a ..."

large touch-sensitive screen connected to a standard computer. The outer display consists of a projection on a large semitransparent surface. Combined, the two displays comprise an IT-supported, collaborative environment especially suited for project based education. Through three iterations of design

Touch Screen Computer Displays

by unknown authors
"... When most people think about a computer display, many may develop a mental picture of an output device. However a computer display can function as both an input device and an output device. A touch sensitive screen provides a computer user with an input interface that doesn’t require extensive compu ..."

Touche: enhancing touch interaction on humans, screens, liquids, and everyday objects

by Munehiko Sato, Ivan Poupyrev, Chris Harrison - In Proc. of CHI , 2012
"... Touché proposes a novel Swept Frequency Capacitive Sensing technique that can not only detect a touch event, but also recognize complex configurations of the human hands and body. Such contextual information significantly enhances touch interaction in a broad range of applications, from conventional ..."

conventional touchscreens to unique contexts and materials. For example, in our explorations we add touch and gesture sensitivity to the human body and liquids. We demonstrate the rich capabilities of Touché with five example setups from different application domains and conduct experimental studies that show

Teaching With an Intelligent Electronic Chalkboard

by Gerald Friedland, Raúl Rojas, Ernesto Tapia - In Proceedings of ACM Multimedia 2004, Workshop on Effective Telepresence , 2004
