Error-free touch technology

The inputs to be made are often very complex, must be error-free and the input must be unambiguous without the user having to tap the touchscreen several times. This requires a well thought-out positioning of the controls, a touch technology that works flawlessly in different environments (temperature, humidity, lighting conditions, electrical interference fields, etc.) and conditions (e.g. strong vibration).

Possible secondary requirements with regard to efficient operability can include high precision of the inputs, efficient error correction mechanisms of the controller or even operability with latex gloves or scalpel.
