DLP Front Projector Technology Turns Virtually Every Surface Into Interactive Experience

LAS VEGAS , June 9 /PRNewswire-FirstCall/ — Texas Instruments (TI) (NYSE: TXN) DLP® Products invented the ability for consumers to interact with a projector's beam of light from anywhere in the room; on virtually any surface without the need for cumbersome calibration.



The interactive functionality from DLP technology has already been recognized and adopted by multiple leading manufacturers. Specific models from the following manufacturers will include the option to display content as either 3D or as 2D with interactivity:

  • Acer
  • BenQ
  • Dell
  • InFocus  
  • ViewSonic

This technology was invented by TI engineer Marshall Capps and DLP was the first projection technology to implement interactive projection. Marshall was recently acknowledged for this innovation in the June issue of Fast Company as one of the “100 Most Creative People in Business.”  

“My mom is a teacher and I heard her frustration expressed more than once about the limitations of being tied to the front of the room when teaching – she couldn't help kids out in the back of the class without stopping the lesson and having kids out of their chairs creating a disturbance,” said  Capps of his invention. “I thought of a way to remedy these issues and created something that allows presenters to spend more time sharing information in a collaborative way.”

DLP's interactive technology allows users to digitally make notes on the projected image with a handheld pen device. Digital patterns from the pen are detected and then sent to the projector over a radio frequency. All information is passed to the computer in the same way as any other mouse or pointer device – you can use this with any software, on any surface without purchasing any additional hardware beyond the pen and projector.  

Unlike other interactive projectors, this DLP technology doesn't require calibration steps and doesn't tie the presenter to the screen or front of the room. He or she can move about the room, or hand the pen to someone at the back of the room to interact with the projected content.

“The value of an interactive solution is undeniable,” said John R. Martin , Ed.D., Director of Learning Resources, Tarrant County College Northwest Campus. “When people have the opportunity to be a part of the presentation, information seems to be better understood and retained, making a DLP Projector more of a collaboration tool than before.”

DLP Projector technology including interactivity, 3D-ready and lamp-free projectors will be on display at DLP booth #C4717.
