Other Parts Discussed in Thread: DLPDLCR2000EVM

Hello,

What would be the cheapest or easiest way to detect touches on the reflected area? I want to build a simple control panel that resembles the smart controls in the ad video.

    Hi,

    Thank you for your interest in the new DLPDLCR2000EVM. We do not currently have a design for this application, but a lot of research has been done recently to do just that. Most solutions need a sensor to measure the X and Y position of your finger, or other object. Things like a time-of-flight sensor, IR, or other computer vision approaches will allow you to do this.  Please let me know if you have any further questions.

    Regards,

    John Varela

    Hello Sel,

    I would suggest that you review the "TI DLP® Pico™technology for smart home applications" paper, which can be found here: www.ti.com/.../dlpc101a.pdf

    This document (particularly on pages 8-9) recommends various options for producing interfaces that can be used with our DLP Pico chipsets. You can decide which technology is most suitable for your application from there.

    I hope this helps, feel free to ask if you have additional questions.

    Best Regards,

    Philippe Dollo
