RotoView Ballistics Tutorial

The program collects data during the RotoView Navigation mode. The data of the most recent navigation session replaces any previous data and is retained for analysis and can be shown in the Ballistics view.

Each line in the ballistics table lists the sensor data and the view navigation computation parameters for the corresponding time ticker. Since view rendering (and ballistics data capture) is the same as the accelerometer frequency, the time ticker period is 40mS when the accelerometer frequency is kept at its default value of 25Hz.

The R column indicates the current value of the mapped Time Response Graph. You can easily correlate the value in this column and the currently selected graph and mapping setting. Sensor rotational data is captured in the Ax, Ay and Az columns. The Dx and Dy indicate the computed view displacement along the X and Y axes. The Act column is an activity detector. The value 'N' indicates inactivity, determined by the Inactivity Threshold setting and the accelerometer data. If exit by inactivity is set, the program counts sufficient consecutive 'N' readings to determine inactivity exit.

Tutorial 4.1: Working with the Ballistics Table

• Step 1. Perform a view navigation session as described in Tutorial 1.1.
• Step 2. Tap More and then tap the Ballistics tab at the bottom tool bar.
• Step 3. Scroll down and up the ballistics table to examine the sensor data and the computation process.
• Step 4. Tap on the middle of the top bar to display the Ballistics Data Legend. Note that you can toggle between a display of Dx, Dy (display movements) and Vx and Vy (display offset).
• Step 5. With understanding of the time response graph mapping gained from tutorial 2.2, verify the graph mapping process shown at the second column 'R'.
• Step 6. To return to the main RotoView screen, do one of the following:
  a. Tap the Settings tab and then Tap the top right RotoView button.
  b. Tap to top right section of the Ballistics top bar.
  c. Repeat Step 4 and select To RotoView.

Tutorial 4.2: Examining Inactivity Exit with the Ballistics Table

• Step 1. Set RotoView for Inactivity exit (as described in Tutorial 1.4) and perform a view navigation session where you stop tilting the device to activate the inactivity exit.
• Step 2. Follow the previous tutorial 4.1 to reach the ballistics table.
• Step 3. Scroll down the ballistics table until the exit point. Notice that the exit was caused by the accumulation of a long string of 'N' markers (inactivity) in the rightmost column.
• Step 4. Verify that there are about 23 'N' markers, assuming you set Inactivity time to 0.9 second and kept the accelerometer frequency at 25Hz.
