Programmers routinely use source code snippets to increase their productivity. However, locating and adapting code snippets to the current context still takes time: for example, variables must be renamed, and dependencies included. We believe that when programmers decide to invest time in creating a new code snippet from scratch, they would also be willing to spend additional effort to make that code snippet configurable and easy to integrate. To explore this insight, we built SnipMatch, a plug-in for the Eclipse IDE. SnipMatch introduces a simple markup that allows snippet authors to specify search patterns and integration instructions. SnipMatch leverages this information, in conjunction with current code context, to improve snippet search and parameterization. For example, when a search query includes local variables, SnipMatch suggests compatible snippets, and automatically adapts them by substituting in these variables. In the lab, we observed that participants integrated snippets faster when using SnipMatch than when using standard Eclipse. Findings from a public deployment to 93 programmers suggest that SnipMatch has become integrated into the work practices of real users.

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.

We propose a novel hand-gesture recognition method based on mechanomyograms (MMGs). Skeletal muscles generate sounds specific to their activity. By recording and analyzing these sounds, MMGs provide means to evaluate the activity. Previous research revealed that specific motions produce specific sounds enabling human motion to be classified based on MMGs. In that research, microphones and accelerometers are often used to record muscle sounds. However, environmental conditions such as noise and human motion itself easily overwhelm such sensors. In this paper, we propose to use piezoelectric-based sensing of MMGs to improve robustness from environmental conditions. The preliminary evaluation shows this method is capable of classifying several hand gestures correctly with high accuracy under certain situations.

Spatial augmented reality (SAR) makes possible the projection of virtual environments into the real world. In this demo, we propose to demonstrate our SAR tools dedicated to the creation of physical drawings. From the most simple tools: the projection on virtual guidelines enabling to trace lines and curves to more advanced techniques enabling stereoscopic drawing through the projection of a 3D scene. This demo presents how we can use computer graphics tools to ease the drawing, and how it will enable new kinds of physical drawings.

In this paper we propose an exploratory augmented real-ity(AR) system for mobile devices. A hybrid system of 3D object detection and 3D tracking is used to rapidly localize the object in the scene. Based on randomized tree classifier, object detection supports large viewpoint changes. While edge-based 3D tracking provides efficient computation and better accuracy for pose estimation of incremental motions. The result is an augmented reality system that works well with large viewpoint variance and has superior accuracy. Using a mobile device such as iPad or iPhone. our system further provides exploratory capability using their touch screen and wireless connectivity. The user is able to interact and explore the 3D object on the image or video, and collaborate with a remote user. Extensive experiments with different subjects demonstrate that the proposed system advances the state-of-the-art in augmented reality with novel and intuitive applications.
