Multitouch table interactively illuminated with 660 LEDs

Our latest multitouch table features an additional way to interact with users: a wraparound LED strip consisting of 660 individually controllable high-performance LEDs.

Remote effect: Touch Table attracts users’ attention with LED lighting

Visual interaction is made possible not only by the table’s large ultra-HD surface, but also by the lighting around the table. Even from a distance of several metres, the table begins to glow faintly on the sides where potential users are located. As a user approaches, this area of the table becomes increasingly illuminated. As the user approaches, the table greets them with a text message on the multitouch surface. This is made possible by the table’s built-in person sensor, which has a range of up to eight metres.

Corporate design compliant: individual lighting effects

The LED light strip can be programmed to match the colour of the table, the corporate design or the multitouch software. It uses optical signals to guide users to the scanner niches in the corners of the table, for example, which are also illuminated by LEDs. This adds to the vibrancy of the multitouch table as a whole.

Technical details of the Touch Table

The LED strip consists of 660 individually controllable APA102 RGB LEDs. Each can display 16.8 million different colours (8-bit colour depth per colour channel). The LEDs are controlled directly from the PC via an SPI interface, enabling fast and smooth animations. As each LED consumes 50mA at 5V at maximum brightness, a good and consistent power supply is essential. For this reason, the LED strip is connected to a powerful 5V/27A power supply at all 4 corners of the table.
