<p>A user-system interface actuates a tub system associated with the tub comprising a tub wall with an opening in the tub wall above a maximum water level of the tub. A screen plate is mounted to the tub wall to cover the opening, the screen plate having keys representing functions of the tub system, and being made of a material allowing visible light/infrared radiations to pass therethrough. Sensors are associated with each one of the keys of the screen plate through the opening in the tub wall and concealed from a visible surface of the tub, the sensors being triggered by electromagnetic radiations of a user across a respective one of the keys. A controller receives actuation signals from the a triggered one of the sensors to actuate any selected function of the tub system.</p> |
