Zytronic has introduced its ZyBrid Edge touch sensor technology to create multi-screen interactive video walls and tables, according to a press release. Designed to mirror the narrowest bezel video wall monitors, the glass sensors feature an ultra-narrow border (anywhere from 3mm to zero). The sensors can be linked when used with the associated new ZyBrid Edge controller to enable seamless touch transition between screens, with potentially no gap between adjacent active areas.

Typically, AV installers fix a huge protective glass over the entire interactive video wall, according to the release. They then often use a clip-on infra-red or camera-based touch detection system around the outside of the tiled screens. This arrangement creates a large, unsightly, protruding bezel around the edge of the wall, even if interactivity is only required on some displays. It also means that if a monitor needs to be adjusted or replaced, the entire cover glass has to be unmounted from the touch detection frame. Also, these touch detection technologies tend to be susceptible to false and accidental touches. They can also be confused by strong direct sunlight. Worse still, if dust and debris accumulate on the surface, the effectiveness of optical transmitters or receivers can be impacted, stopping the interactive video wall from working altogether.

Current alternative technologies, such as conventional projected capacitive or acoustic based touch systems, have wider borders that detract from a closely tiled, aesthetic appearance.

Zytronic has also designed proprietary firmware for the ZXY500 controllers, allowing the data from the individual associate controllers to be “stitched” together by the primary controller, which then presents a single set of x-y coordinates to the host computer as a USB HID “plug and play” touchscreen device.

This approach solves the problem of dropped touch coordinates as a user passes their fingers from one screen to an adjacent unit to achieve a seamless coordinate and touch contact ID transfer “handshake” no matter how many people interact with the video wall.

The individual touch sensors can be attached to the underlying ultra-narrow bezel displays using suitably designed frames or optical bonding. When tiled alongside, each screen’s touch controller is linked to create a near-borderless interactive wall.

A further benefit of this individual yet linked and tiled approach is that only the individual monitors within reach of users’ fingertips need to be fitted with the ZyBrid Edge touch sensors.
