In Part I of this series, we explored the differences between user interfaces based on mechanical buttons and those utilizing capacitive touch sensors. In Step 1 we discussed the look and feel of a ...

Adding pressure to a human-machine-interface (HMI) touch control can make it far more intuitive to use and allow it to recognize much more than simply “on” and “off.” With this new 3D information, a ...

You can’t have a touch sensitive switch without a way to detect the presence of a finger! A touch sensor, especially a capacitive touch sensor, has some surprisingly sophisticated electronics to ...

Apple on Tuesday was granted a patent for an ultrasound-based force and touch sensor that could lead to a thinner, less obstructive 3D Touch mechanism, a structure which was reportedly a barrier to ...

TL;DR: The USPTO granted Apple several patents this week. A touch interface that covers the entire device is one of the more intriguing ones. The concept would use touch sensors embedded in the ...

Capacitive sensors supply high accuracy at a relatively low cost. But system designers attempting to use them have been forced to first convert the capacitance to a voltage, then convert the voltage ...
