When you want people to interact differently with your touchscreen, what do you do? For example, you might want to bring the benefits of a product to life using an interactive table, where different aspects of the user experience are displayed as you move it around the surface. Or perhaps you have a touch display that would be more user friendly with a ‘dial’ function? Not easy to achieve with just fingers. How do you bring the physical and digital together in an easy and fun way?
Examples of plastic tags with 3 conductive elements
Our SimplePlus capacitive touch screens can now offer a new object recognition system which brings such ideas to life. Where you might normally just use human touch, we can offer conductive tags, which fit under the object you wish to move around the screen.
These serve as an electrical conductor to stimulate the electrostatic field of the touch screen. Your chosen object is recognized when its tags interfere with the electric field that is projected above the surface of the touch screen. This change in capacitance is detected by the controller which interprets the X and Y coordinates of the event.
In the second image, you can see how products might look when tagged and on a touch surface. When the tags sit on the touch, the connected PC recognizes in real-time the position of the conductive elements on each tag and displays the appropriate information to each individual object.
It’s an extremely cost-effective solution, with excellent display image quality that remains so under all light conditions due to a clear and transparent touch sensor. The tags require no battery or power source, and the surface remains sensitive to both the object and touch detection.
We would typically expect to see such object recognition tables in museums, retail stores, educational settings, for entertainment purposes, at trade shows and on counters and bars. But, of course, our customers are endlessly innovative and we’ll no doubt be seeing these in plenty of exciting and unexpected places!
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.
