Touchable Holography uses Wiimotes to add touch to holograms
Researchers from The University of Tokyo have demoed a touchable hologram at Siggraph 2009. The project, called Touchable Holography, involves the use of Wiimotes placed above the display to track hand motion, and an airborne ultrasound tactile display created in the university's lab to create the sensation of touch. The result is a holographic image that produces tactile feedback without any actual touching, and without degrading the image itself. Check out the video after the break for a fuller, more stunning explanation. [Thanks, Adam]
Invisible flash produces photos without glares
Dilip Krishnan and Rob Fergus at New York University have developed a dark or invisible flash which uses infrared and UV light to take photos in dark places without the nasty glare of a standard flash. Their dark flash camera is made by modifying a flashbulb so that it emits light over a wider range of frequencies and filters out the visible light, and removes filters that prevent the silicon image sensor from detecting IR and UV rays. This flash results in a crisp image which does not have correct color balance, and looks like night vision photography. To correct the colors of the image, the camera also takes a quick color image sans flash right after the dark flash image. The image produced in this second image is predictably grainy and unclear, but the colors are correct. Software is then used to combine the information from the photos to produce the final image (an example of which you see above). There are some minor problems with the method -- objects that absorb UV light (such as freckles!) do not show up using this method. The pair will present their work at the Siggraph conference in New Orleans in August.
Will Wright to keynote SIGGRAPH 2009
There's just something about Will Wright that makes us melt. His choice in games. His geeky good looks. His ability to play god. Whatever it is, maybe the esteemed game designer will shed some light on our infatuation when he takes the stage as the keynote speaker at SIGGRAPH 2009. His presence marks an "expanded" gaming focus for the CGI tech fest, which normally centers on what's new and bleeding edge with all things graphics. The topic of Wright's discussion has not yet been released, though we'll be listening with bated breath when the show opens its doors in New Orleans in early August.
