A New Way to Interact With Your Touch Enabled System

Force Sensing combined with Capacitive Touch has been around for several years as an potential UI enhancement although it has never become a mainstream technology due to consistency in operation, particularly on larger screen diagonals and in harsh environments.

The recent introduction of Force Touch and 3D Touch to mobile handsets, wearables and PC products has renewed interest in the technology although at TouchNetix we believe the mainstream use cases will be different for Industrial, Automotive, Medical and similar product applications.

The screen capture shown above gives a feel for the potential of this new technology which is primarily aimed at screens >5" diagonal. This image shows an application running in Windows which draws a line width which is directly proportional to how hard the user presses the front lens. A typical resitive touchscreen responds to ~100g of press so our capacitive pressScreen can provide a similar user experience without the wearout and optical disadvantages. The technology is similar to force sensing but is implemented in a way which is entirely robust and suitable for high reliability and integrity applications.

What is a capacitive pressScreen?

Capacitive pressScreen is a new technology which is based on the widely deployed and familiar projected multi-touch capacitive touchscreen technology used in mobile handsets and tablet PC's and which adds an extra layer of functionality as the screen is pressed and touched at the same time.


The system responds in the normal way to mutiple touch points on the screen and adds the extra layer of press information in an integrated and proportional way for the whole touch surface. This information can either be used or ignored by the OS, as required.


There are many possible applications for this kind of system, a few are listed below:

  • Emulating mouse clicks by pressing the surface
  • Confirmation that a 'touch' is intentional in a high integrity system
  • Line-width sensitive applications such as drawing or painting
  • Opens the possibility to add haptic effects to the system (with additional hardware)


Market  segments where we believe this will be of particular interest:

  • Point of sale terminals
  • Automotive applications
  • Critical industrial applications needing 2 levels of verified user action and where a mis-identified user intention could lead to catastrophic consequences.

Responsiveness & Performance

TouchNetix has developed this new technology to be responsive and easy to deploy. The system has a good dynamic response and so can identify not only finger pressure but also 'tap' intensity as shown in the above screen capture. The system responds unifirmly across the surface from the lightest 'feather' touch through to some Kg of integrated pressure.


TouchNetix experience of deploying capacitive touchscreens in the most demanding environments has guided the development of our press sensing technology to ensure it can be deployed in high EMC and other aggressive environments which are not typically seen in lower end consumer applications such as mobile handsets.
