Special Touch Control Firmware Developments

Object Recognition

Our object recognition technology allows for an enhanced way of engaging with users to create a more immersive experience with interactive content. Our solution is based on the attachment of passive conductive markers to the base of specially designed objects. The markers replicate finger touchpoints and can be used to activate certain areas of the touchscreen. The special firmware and output protocol we have developed to accompany these objects, identifies the unique pattern of each, and then provides the information necessary to enable software developers to design unique graphical user interfaces (GUI’s) in suitable software packages such as Unity, to react in specific ways to the presence of the object on the touchscreen.

Palm Rejection

Palm rejection is inbuilt into all of our touch controller firmware so that the presence of unusual, large objects on the touchscreen are be recognised and ignored as an anomalous touch, such as a user accidentally leaning on the surface of the sensor with their hand or arm. The level of palm rejection can be altered by the system designer according to the application requirements using our ZyConfig software utility, freely downloadable from the Support section of our website: https://zytronic.co.uk/support/downloads/

Soft Keys

In certain applications, fixed buttons or keys surrounding a dynamic touch area are desirable. This allows for fewer moving parts, easier integration and a smaller bill of materials (BOM). Our latest ZXY500 touch controller firmware enables system designers to create their own unique touch surfaces, combining fixed capacitive ‘buttons’ and keyboards together with dynamic touch areas – all managed by the same touch controller and providing a seamless, wipe-clean interface.

Force Sensing

Our force sensing firmware enables Zytronic touch sensors to register varying amounts of finger pressure on the screen and respond accordingly, providing the system/software developer with Z (or depth) coordinates along with the X-Y (or positional) coordinates. This turns a ‘digital’ touch interface into much more of an adaptable ‘analogue’ device - providing additional touchscreen use data, that can be used to magnify displayed images, activate icons/menus differently according to touch pressure, etc. and open up a whole new world of touch interactivity.
