  • Analog input mapping for hand-held computing devices
    Patent number: 7372450
    Abstract: A first hand-held computing device includes an analog input device and a processor. The analog input device generates analog input. The processor receives the analog input and converts the analog input to coordinates. The processor then maps the coordinates to a button for a second hand-held computing device and generates an event indicating a state of the button for the second hand-held computing device.

  • System and method for generating an analog signal in a hand-held computing device
    Publication number: 20040222965
    Abstract: A system is described for generating an analog signal representing displacement information in a hand-held computing device. In one embodiment, a hand-held computing device includes a housing sized so that a user can hold the computing device during operation. The device also includes a display and a set of controls integrated with the housing so that the user can input information to the device's processor using his or her digits. At least one of the controls is an analog input device configured such that when displaced it generates an analog signal representing that displacement.
