Abstract: In response to a current gesture performed by a user interacting with an application, a gesture detection module accesses a plurality of predefined control gestures, and compares the current gesture with the plurality of predefined control gestures. The gesture detection module detects whether the current gesture matches at least an initial partial gesture of a particular control gesture associated with at least one application function. A feedback generator module generates confirmation feedback for the user if the current gesture matches at least an initial partial gesture of the particular control gesture. The confirmation feedback encodes, for the user, at least a first information identifying the application function associated with the particular control gesture and a second information about a time interval remaining before the associated application function will be executed. The application triggers the associated function if the particular control gesture is completed during said time interval.
