ABSTRACT:
The invention, relates to a method for enabling a user to input messages into a data prossing system. To each message a respective target zone (202) in a virtual workspace (200) is allocated. A tactual representation of the virtual workspace is generated by applying forces to a member of an input device which has a housing with respect to which the member is user-manipulatable. Manipulations of the member are converted to locations of a control object in the virtual workspace (200). On the basis of the tactual representation the user can navigate through the virtual workspace. A message is selected for input in response to a movement of the control object to a corresponding one of the respective target zones (202). The target zones (202) are arranged in the virtual workspace (200) around a central zero zone (204) being a preferred zone of the control object, such that the target zones (202) have substantially no tangential overlap among one another with respect to the zero zone (204).
