On March 24th, Beijing time, the epidemic has spread and the demand for non-touch screens has grown. The epidemic continues to spread. In order to avoid infection and reduce touching the surface of objects, non-contact payment and non-touch panel related technologies have gradually emerged. Countries also call on the public to maintain hygiene and implement hygiene measures such as frequent hand washing and wearing masks to reduce the spread of the virus. Probability.
GTK cooperates with the British fabless semiconductor company TouchNetix to develop a new non-touch user interface. The TouchNetix aXiom chip allows the touch sensor to detect the user's hand movement at a distance of 5 to 6 cm from the screen, replacing the traditional touch screen click and slide Gesture.
TouchNetix's IC is designed for capacitive sensing in complex electrical environments. To develop non-touch technology requires a lot of mathematical operations. The signal is a narrow frequency sine wave, with a relative front end, and the customized digital signal processor (DSP) will get the signal-to-noise ratio; the back-end microprocessor gets high reliability from the DSP Degree signal.
GTK combines its technology with color displays and various user interfaces; the TouchNetix aXiom chip uses a narrow-band signal and a mathematical processing chain to extract perceptual signal information from the detected return signal.
GTK business manager Clive Dickinson said that COVID-19 has completely changed the way people use public equipment, and people also pay more attention to hygiene habits. The demand for non-touch screens in daily life and industrial applications is gradually increasing. He hopes that this technology can be deployed in elevators and ticket sales. Machines, self-service kiosks, cashier counters and other places.
