I ran across an article about Microsoft Research that was interesting... Since its founding in 1991, Microsoft Research has produced a number of technologies that have gone on to find their way into key products for the company. Today at Microsoft's Professional Developer's Conference, the group used the event's final keynote to show what might be ahead in future offerings. While Microsoft Research has played a role in developing everything from Microsoft Windows 95 to Xbox Live, the group's head, Rick Rashid, has his own notable legacy, having developed the Mach microkernel back in the 1980s. ...this is what caught my eye: The final demo was SecondLight, an upgrade to Microsoft's Surface touchscreen tabletop PC design. SecondLight embeds a second, hidden image into Surface's main display, which can only be seen when projected translucent screens held above the device's surface.  | | Microsoft Research's SecondLight project. Source: Microsoft | The upshot? A user can hold a piece of translucent material over the display to reveal additional information on an image. For instance, Steve Hodges of Microsoft Research in Cambridge, England, demonstrated the effect using a mere sheet of paper held over a SecondLight flat screen. SecondLight uses a projector mounted underneath the tabletop screen, along with and an infrared camera on the table. This allows for a secondary image to be projected along with the first without interfering with each other. Read the full article here.
