The present work describes an early research activity on a haptic user interface to assist visually impaired in using a multi-experience shower that saves energy and water and informs the user about current consumptions. The user interface aims to joint visual, tactile and kinesthetic feedbacks to improve digital contents accessibility. The knob is applied both to interact with the graphic interface by able-bodied persons and to emboss Braille text to drive the blind in navigating the menu items. The developed prototype is then illustrated.
