Contactless operation

With our new technologies for contactless operation (Hover Touch & Radar Gesture Control), we offer various solutions for protection against germ and virus transmission. The technologies can be included in new display designs as well as retrofitted in existing systems.

The functions are particularly suitable for publicly accessible vending machines and operating systems such as coffee machines, supermarket scales, ticket vending machines or order terminals. Interactive information displays in shopping centers, pedestrian zones or museums also benefit from these options.

Detailed information on this topic is available in our article in the trade journal PC & Industrie (9/2021).


Hover Touch Technology

Devices with Hover Touch already detect the finger several centimeters in front of the glass surface, whereby a touch event can be executed by briefly remaining in one area of the screen.

As can be seen in our YouTube video, contactless operation is even possible with gloves or input pens.

Right now, the feature can be added to our POS-IQ-PRO devices.

Contactless and tactile operation are available in parallel:

Tactile 2D touch operation

  • Multi-touch with up to 10 fingers
  • supports passive stylus and thick gloves
  • No water or palm recognition possible


Contactless 3D touch operation

  • Single floating finger with a distance up to 5 cm
  • Supports passive stylus and thick gloves
