Abstract

This article describes a remote input device of a computer, which is composed by a stick with Light Emitting Diodes (LEDs) and switches to turn on/off each LED, an image processing subsystem with a CCD camera to calculate the position of LEDs and another subsystem to translate the position data of LEDs to mouse input and/or keyboard input of the computer. Position data of LEDs can be retrieved and translated to input data of the computer by manipulating the stick within the field of view of the CCD camera.

Integrated Remote Input Device

      This article describes a remote input device of a computer,
which is composed by a stick with Light Emitting Diodes (LEDs) and
switches to turn on/off each LED, an image processing subsystem with
a CCD camera to calculate the position of LEDs and another subsystem
to translate the position data of LEDs to mouse input and/or keyboard
input of the computer.  Position data of LEDs can be retrieved and
translated to input data of the computer by manipulating the stick
within the field of view of the CCD camera.

In the case of mouse emulation, process flow is the following:

o   The operator manipulates the stick in front of the CCD camera.

o   The operator can see the monitor TV of the image processor in
    order to get feedback of the stick position in the field of view
    of the camera.  One LED is equipped on top of the stick, and the
    LED is kept on.  A second LED is quipped below the top LED, and
    the second LED is turned on by pressing the switch of the stick.

o   The image processor grabs the image from the CCD camera and
    calculates the position of the top LED continuously.

o   The coordinates of the top LED is converted to pseudo mouse
    output  signal by the translation subsystem.

o   If the second LED below the top LED is turned on, this
    information is converted to the mouse button status which
    indicates the pressing of the mouse button.

In the case of keyboard emulatio...
