Touchscreen technology has been indispensable for years. Be it the smartphone, the tablet PC or the industrial touchscreen. Operating a surface or triggering different functions by swiping and swiping has been a common everyday gesture of the hand for years.
Manufacturers such as Samsung filed the first patents for pressure-sensitive displays as early as 2014 (see source). This new operating concept allows the user to operate a mobile device not only with the usual finger gestures, but also to exert vertical inputs with pressure. Depending on how hard you touch the display with your finger, different functions are performed.
A sensor measures the pressure intensity
Pressure-sensitive touchscreens usually have sensors that can measure and transmit the strength of a touch. Graphics tablets that are operated with a pen, on which pressure is also exerted, also work in a similar way, for example to change the line width.
In the case of a pressure-sensitive touchscreen, for example, this function can be used to equip virtual buttons with different commands, depending on how differently they are pressed. Such functions can now be found in many smartphones or navigation displays of numerous car manufacturers. There are also virtual controls for portable tablet PCs equipped with this technology in the industrial sector.
