Also included in the kit are strips of infrared LEDs that shine light onto the back of the screen, much like the infrared light sources that Microsoft uses. In her kit, she includes a tabletop screen that has a coating that makes it easier for the camera to track objects, she says. Wagenknecht says that a user simply needs to plug the webcam into a computer, install software available on the Cubit project’s site, plug in the projector, and project images onto the screen. The single camera inside the table can be a simple webcam with an added infrared filter, and a small image projector can be purchased for about $300. ![]() Cubit is a boxy table with a clear surface. Wagenknecht says that her system works in a similar way. Currently, Microsoft has no plans to open the hardware or software of the system to developers. When an object such as a finger or a cell phone is in contact with the surface, it reflects the infrared light in a characteristic way, and the reflection is picked up by the cameras below. According to Kyle Warnick, a Microsoft marketing manager, both the projector and the infrared emitter shine onto the tabletop from underneath. Microsoft’s Surface has an image projector, infrared-light emitters, and five cameras nestled in its base. But because of the falling costs of many touch-screen components, such as infrared light sources and small cameras and projectors, it’s now becoming feasible for people without access to a lab or venture-capital money to make their own multitouch displays. Mitsubishi Electric Research Labs created an iconic multitouch table called DiamondTouch more recently, Jeff Han, founder of Perceptive Pixel, based in New York, developed wall-sized multitouch screens that he sells to corporations and major government agencies. Multitouch displays are not new technology in fact, they’ve been built in research labs for decades. Putting together a personal multitouch table could cost anywhere from $500 to $1,000, depending on the type of hardware used, Wagenknecht says. In addition to making Cubit software available online, Wagenknecht is selling various do-it-yourself kits that include parts and instructions, aimed at people with a range of engineering skills. The bottom picture shows the Cubit unit, fully assembled.Īddie Wagenknecht, a fellow at Eyebeam, designed Cubit in an attempt to “demystify multitouch.” She and her collaborator Stefan Hechenberger “wanted to prove that anyone could build if they had a few simple things,” she says. ![]() The top picture shows a user whose fingers are leaving traces on the table’s surface. Hands-on hardware: Cubit is an open-source, multitouch, tabletop display, similar to Microsoft’s Surface but less expensive and requiring assembly. But they’re also fostering innovation by giving engineers an open platform on which to develop novel multitouch applications–something that they’ve previously lacked. By sharing the Cubit’s hardware schematics and software source code, the engineers are significantly reducing the cost of owning a multitouch table. But now engineers at Eyebeam, an art and technology center based in New York, have created a scaled-down open-source version of Surface, called Cubit.
