We introduce SpeckleEye, design and implementation of an embedded gesture and real-time motion tracking system using laser speckle. SpeckleEye is a low-cost, scalable, open source toolkit for embedded speckle sensing and gestural interaction with ubiquitous devices in the environment. We describe embedded speckle sensing hardware and firmware, a cross-platform gesture recognition library optimized to run on embedded processors, and a set of prototypes that illustrate the flexibility of our platform.

How will the world look with a one trillion frame per second camera? Although such a camera does not exist today, we converted high end research equipment to produce conventional movies at 0.5 trillion (5· 1011) frames per second, with light moving barely 0.6 mm in each frame. Our camera has the game changing ability to capture objects moving at the speed of light. Inspired by the classic high speed photography art of Harold Edgerton [Kayafas and Edgerton 1987] we use this camera to capture movies of several scenes.
