Presentation Transcript

  1. Who Am I ? • Jingtao Wang, Assistant Professor in CS and LRDC (jingtaow@pitt.edu , will become jingtaow@cs.pitt.edu eventually) Office 5423 SENSQ • http://www.cs.pitt.edu/~jingtaow • Ph.D. in Computer Science from UC Berkeley • Originally from China, worked as a researcher at IBM China Research Lab for three years after getting M.S. and B.S. degrees from Xi’an Jiaotong University • Primary research direction - Human Computer Interaction (HCI) • Mobile interfaces, the application of machine learning in HCI and education/learning

  2. Past Projects

  3. Embodied Visual Exploration of Multidimensional Scatterplots on Mobile Devices • Scatterplots is one of the most widely-used visual representations for multidimensional data • Even if we employ 3D graphics, point color, shape, and size as graphical properties, a standard scatterplot diagram can only visually represent a handful of data dimensions at a time. • It becomes more challenging on mobile devices with the limitation of screen size, screen resolution and input devices disc.sci.gsfc.nasa.gov Source: www.moleculardevices.com www.japanreview.net

  4. Project Outline • Using a Scatterplot Matrix [Elmqvist 2008] to present a global overview of the different dimensions and historical navigations of the data set • Using embodied interaction techniques (Yaw, pitch, and roll rotations, pinch/zoom) to navigate the scatterplot matrix interactively [Elmqvist 2008]

  5. Designing A New Phrase Set for Evaluating Mobile Text Entry Techniques in the “Twitter Age” • Text entry on mobile devices present unique challenges to the fields of human computer interaction • Many mobile text entry methods have been invented in the past 15 years. To verify the efficacy of a new technique, one has to run a typical A vs. B style benchmark on a set of test phrases • The most popular mobile phrase set – [MacKenzie 2003], were designed to emulate the character/word/di-graph properties of English novels. It’s becoming less representative/relevant in the “Twitter Age”
