  • Page 37 System Operation Figure 5-3. Right-Hand Rule Showing the X, Y, Z Axis The second right-hand rule allows you to point your thumb in the positive direction of any axis and to curl your four fingers to represent positive rotation about that axis. In Figure 5-3, the thumb is pointed along the positive X axis, and the four fingers curl in the direction of positive rotation about that axis.

  • Page 38: Origin Points And Reference Axes

    Chapter 5 Origin Points and Reference Axes The positional and orientation data generated by the control unit are based on the 3D origin points and reference axes. In Figure 5-4, the transmitter’s origin point and reference axes are defined by the following: •...

  • Page 39: Positional X, Y, Z Data

    System Operation Transmitter Origin Receiver Origin Figure 5-4. Transmitter and Receiver Origin Points and Reference Axes Positional X, Y, Z Data Positional data is the distance between the transmitter’s and receiver’s origin points. X Data. This is the distance the receiver’s origin point is to the left or right (along the X axis) of the transmitter’s origin point (see Figure 5-4).

  • Page 40: Orientation Data

    Chapter 5 Z Data. This is the distance the receiver’s origin point is away (along the Z axis) from the transmitter’s origin point-minus an 18-inch offset (see Figure 5-4). When the receiver is 6 inches away from the transmitter the Z axis, the Z data will be approximately a negative 12 inches. Orientation Data Orientation describes the rotation of the receiver with respect to the transmitter.
  • Page 41 System Operation Yaw. Yaw orientation is positive or negative rotation about the receiver’s Y axis. Figure 5-6 shows positive Yaw rotation. Figure 5-6. Positive Yaw Rotation Roll. Roll orientation is positive or negative rotation about the receiver’s Z axis. Figure 5-7 shows positive Roll rotation. Figure 5-7.

  • Page 42: Converting Euler's Angles To Quaternions

    Chapter 5 Orientation data is represented in Y-X-Z Euler’s angles. For example, the orientation of 0 degrees Pitch, 0 degrees Yaw, and 0 degrees Roll is reported when both of the following conditions are met: • The receiver’s reference axis Z is parallel to the transmitter’s reference axis Z (see Figure 5-4).

  • Page 43: Converting Degrees To Radians

    System Operation Converting Degrees to Radians Radians are a unit of angular measure for rotation. If you prefer to use radians instead of degrees, the following formulas will help you convert from degrees. To convert degrees to radians, use the following formulas: P = P •...

  • Page 44: Resolution

    Chapter 5 Resolution In 3D mode within the active area, the resolution along the X, Y, and Z axes is 1/250 of an inch. The resolution in the Pitch, Yaw, and Roll rotations is 1/10 of a degree. Fringe Area and Out-of-Range Area The fringe area is a 1-foot band along the edge, within the active area (see the block diagram in Figure 5-9).
  • Page 45 System Operation When the receiver is out of range, the control unit sets an OUT bit in the first byte of its data report to the host computer. This data report contains the last valid report when the receiver was in range. This last valid report allows the application to use the returned data report.
  • Page 46 // first report valid? if (report [0] & logitech_OUTBIT) { // first report invalid, request user to move the receiver printf (“Please move the Logitech receiver in range.\n”); // stick around until I get a valid data report do { // go get another report get_report (report);...

  • Page 47: Tracking Speed

    System Operation OUT Bit Set-Out of Range or Obscured. After the first data report, the unit always has a last-valid data report. Therefore when the receiver moves out of range or the ultrasonic path is obstructed, the position and orientation data reflects the last valid data report. For applications that convert absolute information to relative changes, the data report can usually be used as is.

  • Page 48: Mode

    Chapter 5 2D Mode In 2D mode, you can move the 3D Mouse on a flat surface (the desktop or table). It behaves like a conventional 2- or 3-button mouse. The control unit reports button activity and two-dimensional movement to the host computer.
