The highly integrated family of aXiom chips already offer rich touchscreen functionality with proximity, hover, touchscreen and force sensing detection, as well as haptic feedback control. The aXiom chip operates using a standard touch-sensing element with up to 112 sensor channels in displays with standard or arbitrary aspect ratios.
TouchNetix’ new aXiom IC features a built-in touchless capability in addition to those other features. The aXiom IC enables Air Dwell, Air Tap, Air Swipe and Air Spin gesture recognition from over 6cm above the touch surface. The new gestures can be used to replace touch functions. The Touchless User Interface technology is supported by gesture recognition software running on the system's controller or processor.
Air gestures can be configured and extended by using a development tool that is supplied by TouchNetix. Normal touchscreen operation is implemented alongside the new touchless controls.
The aXiom chip uses the touchscreen's normal touch sensor element to implement gesture sensing. It requires no additional electrodes, board-level components, sensors or other hardware. This means touchscreen manufacturers can quickly develop a new touchscreen product with touchless interface capability, while having a lower component count and system cost than competing solutions.
Chris Ard, Managing Director of TouchNetix, said: 'The easy implementation of intuitive gesture controls such as Air Tap and Air Spin enables manufacturers of multi-user touch interfaces to enable hygienic use without the risk that users will pass on or pick up viruses, bacteria or other contaminants on their fingers. Medical applications can also benefit from the improved hygiene that the aXiom touchless user interface controls can provide.’
'There is very strong market interest for touchless controls now the world has been made hyper-aware of disease transmission via hand contact since the emergence of the COVID-19 pandemic. Now touchscreen manufacturers have an easier and more integrated way to implement gesture control and eliminate the need for users to touch the surface of the screen.'
TouchNetix is currently looking for additional manufacturing
