Sensing the force

To address interest and growth in the space of interactive videowalls and large touch tables, Zytronic is showing its force sensing technology for large-format interactive touch screens for the first time at ISE.

Zytronic will be demonstrating PCT and MPCT touch sensors with force sensing in ATMs, kiosks, game terminals and interactive videowalls, to differentiate between a soft and hard touch.

Zytronic’s approach is based on a measurement of the surface area of an applied touch, which changes the measured capacitive signal levels at the relative touch location on the sensor. This eliminates the need for a piezo-electric or other layers on the glass to measure applied force or pressure. Since it relies on a modification to the firmware, it can be retrofitted to existing Zytronic touch screens.

“Force or pressure sensing is a whole new way of interacting with a touch screen and we are a pioneer in bringing it to financial, retail, gaming, industrial and other commercial touch screen applications, giving developers a fantastic opportunity to innovate,” commented Ian Crosby, sales and marketing director at Zytronic.
