Canesta Licensee and Tessera Subsidiary Cooperate on Virtual Keyboard

Seoul, Korea-based Canesta 3D-sensing patents licensee Celluon and DigitalOptics Corporation (DOC), a wholly owned subsidiary of Tessera (used to be Imaging and Optics division in the past), partnered to deliver a custom diffractive optical element (DOE) that projects a virtual computer keyboard.

DOC developed the DOE for use in Celluon's MagicCube, an ultra-portable, full-sized virtual computer keyboard. DigitalOptics will be the sole manufacturer of the new keyboard DOE, which will be available in multiple languages, for Celluon, a vendor of portable input applications.

"Our laser key projection keyboard is a revolutionary step in mobile input," said Ray Cha, CEO of Celluon, Seoul, Korea. "This new DOE from DigitalOptics enables Celluon's MagicCube to extend its capabilities as a leading projection keyboard using the 3D electronic perception technology."

  1. But this kind of devices doesn't need ToF sensor, am I right?

  2. Celluon talks about 3D sensor, not telling if it's ToF or something else.

  3. I thought Canesta had been thinking about this idea for a long time. I remember I read something about it a while back. Am I correct?

  4. Yeah, they've had the base technology to do this from at least 2004.

  5. 2004 is about the time when Celluon was established, formed JV with Canesta and got $950K from Canesta. See Celluon history here:

  6. I had old Celluon device, took it apart, of course :) And I guess it's time modulated IR laser line (horizontal, near surface) and sensor with simple demodulation pixels (or subtraction of two (on/off) images). I'm quite sure it's based on simple triangulation.

  7. $199 is too high a price!
