Abstract:
1. A control device for controlling properties of light emitted from a light source, comprising: a touch-sensitive user interface for visually indicating a range of available values representing at least one property and to enable a user to control said at least one property on the basis of a location touched on said touch-sensitive user interface, thereby providing the control device with user input; a communication unit for adjusting said at least one property by means of communicating, to the light source, control signals corresponding to said user input; wherein said touch-sensitive user interface comprises at least one discontinuity-indicating element for visually indicating a step discontinuity in said range of available values representing said at least one property; and an audio feedback unit for generating an audio signal that identifies the at least one property in response to the user input, wherein the control device is configured to facilitate the user input comprising a sliding motion going past a region of the touch-sensitive user interface including the step continuity from the one-sided limit from a positive direction to the one-sided limit from a negative direction, or vice versa, and deactivate said audio feedback unit.
