Abstract: A method includes arranging, by a computer, multiple interactive objects as a hierarchical data structure, each node of the hierarchical data structure associated with a respective one of the multiple interactive objects, and presenting, on a display coupled to the computer, a first subset of the multiple interactive objects that are associated with one or more child nodes of one of the multiple interactive objects. A sequence of three-dimensional (3D) maps including at least part of a hand of a user positioned in proximity to the display is received, and the hand performing a transverse gesture followed by a grab gesture followed by a longitudinal gesture followed by an execute gesture is identified in the sequence of three-dimensional (3D) maps, and an operation associated with the selected object is accordingly performed.

Abstract: A communication system, including a mobile communicator including a modem for conducting a communication with a remote party, an input unit for inputting communication data to the modem, and an output for outputting communication data from the modem, a display device including an input unit, an output unit, a connector for engaging the mobile communicator and for exchanging data with the mobile communicator, and a display for displaying party-specific information about the remote party involved in the communication, wherein the modem switches to receive its communication input via the display device input unit and directs its communication output to the display output unit when the mobile communicator is engaged with the connector, and wherein the modem switches back to receive its communication input via the mobile communicator input unit and directs its communication output to the mobile communicator output unit when the mobile communicator is disengaged from the connector.

Abstract: A user interface for a mobile electronic device, including a slider bar that supports three user inputs; namely, (i) slide up, (ii) slide down, and (iii) press, wherein slide up and slide down cause respective scrolling up and scrolling down through a menu of items, and wherein press causes selection of a scrolled-to menu item.
