Title: Text entry methods for touch screen and pen-based devices

Speaker: Gennaro Costagliola (University of Salerno, Italy)

Time: 10:00am, August 20th, 2013

Venue: Lecture Room, 3rd Floor, Building #5, State Key Laboratory of Computer Science, Institute of Software, Chinese Academy of Sciences

Abstract: In this talk, I will go through the principal methods for the text entry on devices such as smart phones and tablets by taking into account fingers and styluses. I will show the problems to face, some simulation models and the techniques needed to evaluate the effectiveness and efficiency of a text entry method. Finally, as a case study, I will present a comparison between the methods KeyScretch and Shapewriter.
