FIELD: control systems.
SUBSTANCE: invention relates to touch screen control. Technical result is achieved by detecting (610), for a certain period of time, two sets of touch screen device, wherein each plurality of touches comprises simultaneous contact by two contact points, determining (620) that the vibroacoustic effects of at least one of the simultaneous touches correspond to a certain profile of the vibroacoustic effects from the multiple profiles of the vibroacoustic effects, which are stored in the device, and starting (630) in the device a predetermined action in response to detection of two sets of touches within a given period of time.
EFFECT: fewer inputs for sampling the desired result.
