One form of input for interacting with large shared surfaces is through mobile devices. These personal devices provide interactive displays as well as numerous sensors to effectuate gestures for input. We examine the possibility of using surface and motion gestures on mobile devices for interacting with 3D objects on large surfaces. If effective use of such devices is possible over large displays, then users can collaborate and carry out complex 3D manipulation tasks, which are not trivial to do. In an attempt to generate design guidelines for this type of interaction, we conducted a guessability study with a dual-surface concept device, which provides users access to information through both its front and back. We elicited a set of end-user surface- and motion-based gestures. Based on our results, we demonstrate reasonably good agreement between gestures for choice of sensory (i.e. tilt), multi-touch and dual-surface input. In this paper we report the results of the guessability study and the design of the gesture-based interface for 3D manipulation. Copyright 2012 ACM.

Large displays are becoming more ubiquitous, but often only present passive information to passerby (e.g., about the 3D layouts and maps of buildings). To improve users' experience, museums and similar places could have a system where users would be able to interactively navigate maps of these public, large buildings to browse quickly what is available and plan their trips so that they are efficient and more enjoyable. Personal touch-based mobile devices can be used effectively as input devices, allowing for opportunistic and serendipitous user interaction. In this paper, we explore the coupling of mobile devices to large displays. We present three interaction styles that enable users to navigate in 3D environments and describe the result of a usability study with the three styles. The results of our study indicate that users prefer a combination of two styles, one supporting discrete, precise motions and the other fluid, continuous movements. Copyright 2012 ACM.

Students tend to retain naive understandings of concepts such as energy and force even after completing physics lessons in science classes. We developed a learning environment called the Virtual Physics System (ViPS) to help students master these concepts in the context of pulleys, a class of simple machines that are difficult to construct and experiment with in the real world. Several features make ViPS unique: it combines simulation and tutoring, it customizes tutoring to address common misconceptions and it employs a pedagogical strategy that identifies student misconceptions and guides students in solving problems through virtual experimentation. This paper describes the ViPS system and studies in which we evaluated its efficacy. Our results indicate that ViPS is effective in helping students learn and overcome their misconceptions.
We apply topic modelling to automatically induce word senses of a target word, and demonstrate that our word sense induction method can be used to automatically detect words with emergent novel senses, as well as toke...
