As part of its continuing effort to maximize efficiency by assessing the effectiveness of its efforts, NASA’s Office of Education contracted with Abt Associates in July 2009 to evaluate the Informal Education Program. The goals of the evaluation are twofold: (1) to gain insight into its investment in informal education; and (2) to clarify existing distinctions between its informal education and outreach efforts. The evaluation findings provide descriptive information about all the projects in the NASA’s education portfolio affiliated with Outcome 3 (Informal Education) and selected Outcome 2
It is increasingly common for software and hardware systems to support touch-based interaction. While the technology to support this interaction is still evolving, common protocols for providing consistent communication between hardware and software are available. However, this is not true for gesture recognition – the act of translating a series of strokes or touches into a system recognizable event. Developers often end up writing code for this process from scratch due to the lack of higher-level frameworks for defining new gestures. Gesture recognition can contain a significant amount of
