Abstract: Disclosed are systems and methods for facilitating the administration of questions to one or more intended responders. A grouping of questions is obtained. At least one graphical element is assigned to each of the questions within the grouping and a grouping of graphical elements is generated. Each of the graphical elements within the grouping of graphical elements is prioritized. In response to detection of a micro-interaction event the following steps are performed: a graphical element among the grouping of graphical elements having a highest priority is selected; the selected graphical element is presented on a display of the mobile computing device; a response is obtained based on manipulation of the displayed graphical element; metadata is generated according to the response; and the response and metadata are stored in a storage device within the mobile computing device.

Abstract: The present invention provides a human-machine interface where control is achieved without the use of buttons. By providing multiple knobs, the audio system maximizes functionality while minimizing cost and space requirements. Each knob is capable of two selection modes: a first selection mode provided by rotating the knob and a second selection mode provided by depressing the knob. The two selection modes correspond to ergonomic selection pairs for controlling the audio system. The reduced area required for controls allows for a larger display area; which provides the user with a more attractive display that can convey more information. When a change in a status, through knob manipulation is sensed by the audio system, the display automatically provides a menu that corresponds to the ergonomic pair assigned to that knob. The automated switching of menus minimizes navigation between screens, while providing full manipulation of that audio system function using a single knob control.
