Extracting depth information from pairs of stereo images in real-time allows interactive 3d operations on live video streams. We present a novel adaptation of the Semi-Global Matching (SGM) Algorithm [Hirschmüller 2005] to graphics processing (GPU) hardware, which operates in real-time and frees the CPU for other tasks. We also present shaders which(More)
Recently, there has been great interest in multi-touch interfaces. Such devices have taken the form of camera-based systems such as Microsoft Surface [de los Reyes et al. 2007] and Perceptive Pixel's FTIR Display [Han 2005] as well as hand-held devices using capacitive sensors such as the Apple iPhone [Jobs et al. 2008]. However, optical systems are(More)
Recently, there has been great interest in multi-touch interfaces. These have taken the form of optical systems such as Microsoft Surface and Perceptive Pixel's FTIR display as well as hand-held devices using capacitive sensors such as the Apple iPhone. However, optical systems are inherently bulky while capacitive systems are only practical in small form(More)
A valinomycin-mediated K+ diffusion potential across the membrane of multilamellar liposomes is stable for longer than 30 min and can be collapsed by a nonselective channel such as gramicidin. The kinetics of the potential collapse are complex but can be qualitatively broken down into a series of processes involving (1) binding of the gramicidin to the(More)
Multi-touch input has been an active area of research for over two decades but has always suffered from the absence of an easily available high quality touch input device. For this reason, exciting user interfaces developed in the lab have appeared on CNN, but not on everyone's desk, computer screens, table-tops, walls and floors. What has been needed - and(More)
