Posted in Raspberry Pi Tagged CCD, cis, ir led, multi touch, raspberry pi, Teensy, touch table Post navigation Here’s one that uses finger presses to scatter light and an industrial strength projection-based table that was open-sourced a few years ago. This is not the only way to build a multi-touch table, nor is it the simplest.
He eventually went wireless and then built a nice looking touch table to house a 32″ TV. A Teensy turns on the LEDs, detects the touch event, calculates the position, and sends those coordinates to a Pi to be displayed on the screen. designed a 3D-printable frame to hold 96 IR LEDs in stacks of three. He ended up with CIS that has 2700 light sensors lined up in the space of 20cm (7.87″). reverse engineered a couple of different types of scanners until he found a suitable one. Keep adding LEDs and their emission angles will begin to overlap, increasing the detection precision. These are a low-power, lower-resolution alternative to the CCDs found in high-grade scanners.Īs explains in the video below, an object placed in the path of a single IR LED facing a sensor array of either type will block the light from reaching the sensors. What’s really happening here is that is using light triangulation to detect shadows and determine the coordinates of the shadow-casting object. Many barcode scanners and consumer-level document scanners use a contact image sensor (CIS) to detect objects in the path of IR LEDs. Of course, it’s a bit of a misnomer to say the surface itself becomes touch-reactive.

In ’s case, that surface is ultimately a TV inside of a table. Ever wanted to build a touch table or other touch-input project, but got stuck figuring out the ‘touch’ part? has your back with his multi-touch frame over on IO that makes any surface touch-reactive.
