But consider another application. Like the whiteboard in the picture, where we want what we write to be instantly transmitted to our PCs. How can we make that happen?
A white board with integrated touch
In collaboration with SIS we have integrated a mesh PCAP behind the plastic cover of the white board and developed a special controller that can drive this plastic mesh stack.
The biggest challenge was connecting the touch to the PC. There can be no defined distance between the White Board and the PC, so it is difficult use a USB cable.
For this reason, together we developed a wireless solution to the touch controller that works over 2.4Ghz RF. In this way the whiteboard and PC can communicate over a distance of several meters – and even through walls!
In the Video you’ll see that when we write on the whiteboard with a standard blue marker, the text appears on the PC.
When we clean the whiteboard with a standard eraser, this too will be recognized by the touch as a palm suppression. The software on the PC will recognize this and delete accordingly.
So, basically, what happens on the whiteboard also happens on the PC.
It’s clearly a great, low cost, way to bring extra efficiency into meetings, with all the notes taken being transmitted to everyone’s PCs wirelessly. All that’s needed is a RF 2.4GHz dongle that can receive the data transmitted by our touch. And, of course, it’s a solution that certainly not limited to interactive whiteboards – we are able to implement this Radio Frequency Controller in every touch-based application.
Extending the 12.1” display size offering, Avnet Displays adds another bright addition to the SimplePlus Touch Display family — combining trusted performance with an even broader choice for our customers.
Technologies tend to come full circle, but in this case we mean literally – combining an advanced rotary encoder (and encoder shell) with a 1.28-inch circular TFT display for a single, compact control solution. Users can navigate with precision by simply turning or pressing the knob, while the integrated screen displays menus, status updates or graphics right at the point of interaction.
