Abstract: A bed system with multiple functions includes a frame structure; a plurality of platforms disposed on the frame structure; an adjustable assembly coupled with the frame structure and the plurality of platforms for operably adjusting one or more of the plurality of platforms in desired positions; a plurality of fans mounted onto openings in the plurality of platforms and adapted for operably providing air circulation in a surrounding space of the bed system, and an aromatherapy system attached onto the one or more platforms for producing desired fragrance in the surrounding space so as to promote health and well-being of a user. Each aromatherapy device is configured to produce a fragrance when said aromatherapy device is turned on, and one or more working modes. The fragrance is identical to or different from that produced by other aromatherapy device of the one or more aromatherapy devices.

Abstract: A method and device for entering data enables intuitive and efficient displays of graphical user interfaces using three dimensional movements of a pointer (205). The method includes associating a first graphical user interface of an electronic device (100) with a first space (210) defined between a control surface such as a display screen (105) and a first plane (215) substantially parallel to the control surface. A second graphical user interface is associated with a second space (220) defined between the first plane (215) and a second plane (225) substantially parallel to the control surface. The second graphical user interface is then displayed on the display screen (105) of the electronic device (100) in response to detecting a location of the pointer (205) within the second space (220). Data are then entered into the electronic device (100) in response to a user interaction with the second graphical user interface.
