The DFA sensor’s variable input force allows for additional, or new, functionality, such as the ability to navigate device menus and perform other operations via single-finger touch. The DFA sensor also allows for correct haptic feedback when the force reaches a pre-selected activation point, a feature that obviates false touch situations.
In multi-touch applications, the DFA’s proportional force sensing feature can determine the ratio of forces between presses (i.e. harder press to left or right), which can have benefits in improved control, especially in gaming applications.
Peratech’s distributed force array sensors are customisable, cost effective, low power and they unlock the next-generation in HMI experiences, enabling new gestures, simplified interfaces, and endless flexibility. Peratech supplies the DFA sensors with control electronics and software.
