Seeking Your Interest in RoadTesting an IR light angle sensor board

rscasny
rscasny over 1 year ago

imageI have had a conversation with a supplier interesting in having the element14 community roadtest its IR light angle sensor board. I don't recall us previously roadtesting this type of sensor (or at least recently within the past year), so let me give you a few facts about it.

If you have the time to explore the device, I'd appreciate you voting in my poll below. Of course, you are free to leave a comment. Many thinks.

Here's a few facts about the board:

EVAL-ADPD2140Z is an evaluation kit to evaluate the ADPD2140 IR light angle sensor, collect data from the ADPD2140, and evaluate gesture recognition and triangulation capabilities. The evaluation kit requires the EVAL-ADPDM3Z evaluation board and the Applications Wavetool, a graphical user interface (GUI) that provides users with low level and high level configurability, real-time data analysis, and user datagram protocol (UDP) transfer capability, which allows the EVAL-ADPDM3Z evaluation board to interface to a PC. The USB port of the PC powers the EVAL-ADPDM3Z evaluation board and provides power to the EVAL-ADPD2140Z evaluation board. On-board voltage regulators provide voltage supplies for the ADPD2140.

Here's some documentation

  • UG-1282: EVAL-ADPDM3Z Evaluation Board User Guide

    It seems that theory of operation is similar to MAX25405 which we experimented with in design challenge: Experimenting with Gesture Sensors . But still it would be nice to see how alternative approaches…

    True, but you could use a reflective ball on the end of a rod to see just how accurately you could make the position locations respond to a series of preset activities. That and you could use it to test…

    obones I agree that the range drives the application. It makes me think of those "foot operated" sensors that are supposed to open passenger vehicle liftgates simply by waving your foot beneath the vehicle…

    I just realized that you could set up two of these boards and do 3D mapping of gestures, that would be a very interesting capability to explore.

    Albeit in a very small cube of 20cm wall size, as stated in the EVAL-ADPD2140Z User Guide:

    > Move a hand or other reflective object within 20 cm directly above the device.

    That's not going to be really easy to move an human hand in such a small volume, but I'm very interested in seeing if it can see anything more than just "the hand went from left to right"

    That and you could use it to test sobriety based upon how steady you could hold your position.

    I seem to manage ok when using a computer mouse / 3D mouse.
