User interface for selecting and controlling plurality of parameters and method for selecting and controlling plurality of parameters

Abstract

A user interface for selecting and controlling a plurality of parameters of a device comprises a touch-sensitive apparatus (100) with a touch-sensitive area (101) and a controller (107). The touch-sensitive area (101) has a closed-loop shape limited at outside by an outer closed curve (105) and at inside by an inner closed curve (106) and capable to receive a touch input, whereas the controller (107) is connected to the touch-sensitive apparatus (100) and configured to detect a starting point (102) of the touch input, detect a touch hold duration at the starting point (102), in case of a touch hold duration not shorter than the activation time, determine a parameter associated with the starting point (102), in case of a hold duration shorter than the activation time, determine a previously controlled parameter, and control the determined parameter while the touch input moves along a control path (103). In addition, the control is sensitive to movement direction.
