V and C Sense explained

Posted 21/04/2017

You may have heard the terms V or C sense technology being associated with a number of the touch displays that A+K have available.        

What does this actually mean and what are the differences between the two types of technology?

V-sense technology (which can be found in the i3TOUCH Excellence series) operates on the basis of light-beam interruption or a ‘beam-break’. It’s essentially a grid reference that creates a ‘V’ shape. Whilst traditional infrared technology is influenced by simulation signal gathering speed, at around 50 fps (frames per second), v-sense has a speed of up to 200 fps. This increase creates a far less clunky and smoother picture on the display.

Again, whilst traditional infrared technology can be altered by ambient light, v-sense overcomes this and gives a much improved result working in strong light. Another key difference is that v-sense displays have a bezel serving to hold the screen in place and have up to 20 interactive touch points. These displays provide a professional yet cost-effective solution and are particularly suited to education environments.  

The i3TOUCH Excellence

Gesture based actions are now second nature to us all and you have probably been using products that use c-sense technology for a long time. C-sense technology is used in the i3 Premium series and the i3HUDDLE 2.0. Capacitive touchscreens work by using the electrical properties of the human body. Our bodies are conductive, meaning electricity can pass through them. So, when we touch a capacitive screen with the top of our finger, we can change the screen’s electrical field, even with the slightest touch.  If you've ever tried to use your iPhone or similar whilst walking outside in the cold, this is the reason you cannot use a capacitive screen whilst wearing gloves! (glove are not conductive). C-sense technology does not rely on pressure, making it much more responsive than a traditional resistive screen, and no stylus is needed. C-sense screens from i3 are also bezel free and have up to 40 interactive touch points.

The i3TOUCH Premium

Both the Premium and Excellence models have shared features of being HID compliant (no calibration needed) and 4mm of anti-reflection safety glass.
