Touchscreen controller also integrates haptics control
The aXiom AX310 is what manufacturer TouchNetix claims to be the industry's first touchscreen controller to be designed specifically for industrial and automotive applications.

The aXiom controller can also perform capacitive proximity sensing at a distance of up to 10 cm, and coarse position sensing of a finger as much as 6 cm distant from the screen. This supports new hover and proximity functions in touchscreen UIs. In addition, the AX310 integrates concurrent force sensing and haptics control, to allow the touchscreen to guide the user's finger through space to their chosen button, touch it, and only register a button press when force is detected at the button's location. The AX310's high-performance force-sensing measurement engine detects displacement of as little as 5 µm. The aXiom controller ICs support touchscreens with up to 56x56 sensing channels, and touch and force-sensing sampling rates of more than 200Hz. They are suitable for use with displays bigger than 15.6" diagonal, and in non-standard form factors and arbitrary aspect ratios. TouchHub development software is provided with the aXiom controllers to ease the design and tuning of touchscreen designs.
