<p>A robotic appliance (10) has a user interface (16) for controlling the appliance. The interface (16) comprises a plurality of user controls (40, 50, 60), each control having an indicator (46, 56A, 56B, 66) closely visibly associated with it. Each control indicator (46, 56A, 56B, 66) is able to provide three different visible states. The visible states are (a) an off state indicative that the associated control is not available for selection, (b) an invitation to operate state indicative that the associated control is available for selection and (c) a selected state indicative of the associated control being selected. The invitation to operate state (b) can be represented by flashing the indicator. The user interface illuminates one of the control indicators in visible state (b) and, in response to a user operating that control, changes the visible state of the control indicator to visible state (c) and illuminates another of the control indicators in visible state (b) whereby to indicate a change in the state of readiness-for-use of the appliance and to guide a user through the start-up procedure.</p> |
