APASview

Introduction

The ARIEL APASVIEW software module has been developed for dynamically viewing stick figures, numerical data and AVI videos. The APASview software module makes it possible to load all data into the computer and simultaneously display and evaluate multiple data sets for a desired sequence.
Although a few of the APASView's features may appear complex, they are relatively easy to master once you understand the underlying concepts. This manual is arranged to teach you these concepts in a logical order by showing you, in step-by-step fashion, how to use APASView.

TO START THE APASVIEW PROGRAM:

1. Double-click the APASVIEW icon located in the APAS System window group. The main APASVIEW window will appear. The APASView VCR Control panel will be displayed in the center of the screen.

SCREEN LAYOUT:

Prior to creating an APASView project, you should take the time to familiarize yourself with the format and contents of the various screens listed below:

THE APASView VCR CONTROL MENU:

The APASView VCR Control menu is designed to mimic the controls on a typical VCR. Besides the normal buttons for controlling a sequence (Play, Stop, Pause, Step Forward, Step Reverse and Single/Continuous Play) the VCR Control menu also includes options for synchronization, display speed and zooming.

Frame - Shows the frame number currently being displayed. It is possible to edit this value to "jump" to a particular frame.
Step - This parameter is used to skip frames in the sequence. If this value is 1, every frame/numerical value is displayed. If the value is 2, only every second frame/numerical value is displayed. This parameter is quite useful if the sequence contains a lot of data sampled at a high rate.

Delay - This parameter is used to control the speed of the animation in the "play" mode. Larger numbers represent longer delays between successive images.

Start - This parameter is used in combination with the Stop parameter to "zoom" the sequence. The Start value is used to specify the first frame/numerical value that will be displayed in a sequence. All active windows will use the Start value.
Stop - This parameter is used in combination with the Start parameter. Stop indicates the last frame/numerical value that will be displayed in a sequence.
SETTING START AND STOP PARAMETERS USING THE DATA WINDOW

Click and hold the right mouse button in the Data Windows, move the mouse left or right. This will mark a specific area of interest in the data signal with dashed vertical lines. Release the mouse button to select the area and the Start and Stop parameters will automatically be adjusted.

THE MAIN APASView TOOL BAR:

The tool bar is located near the top of the window. Icons are pictorial representations of commands or functions. You can access the following commands by clicking the appropriate icon.

Open New Project - Selected to create a new APASView project file.
Open Existing Project - Selected to open a previously created APASView project file.

DATA WINDOW DISPLAY:

he Data Window can be used to display almost any kind of numerical data collected over time. For example, displacement, velocity, acceleration, segment angles joint angles, force, EMG and more.
Producing a graph is a two-step process. First, individual data curves are specified and the data values are read and saved in the display grid. Second, the actual graph is drawn, using these data curves.

THE GRAPH WINDOW TOOL BAR:

Bar Graph - Changes specified data to bar graph format
Line Graph - Changes specified data to line graph format
Spreadsheet - Changes specified data to spreadsheet format
Multiple - Displays all the specified data on a single graph
Single - Displays each data curve on an individual line graph
Setup - Selected to modify/edit the contents of the Graph window.
Copy - Copies the current contents to the Windows clipboard

Print - Prints the current contents to the printer
Help - Displays the help topics for the Graph Window

CREATING A NEW GRAPH WINDOW:

he basic steps for creating a Graph window are listed below.

1. Select DISPLAY, NEW DATA (or the NEW GRAPH icon in the main Toolbar) to open the Data ViewSetup menu.

2. Specify the desired data as either 3D (video data) or ANA (analog data).
3. Click the FILE button and double-click the desired APAS data file. This file is created by the Transform module and has a *.3D extension.
4. Click the ADD button to open the Specify 3D Data Trial menu.

5. Select the desired Type (Linear, Segment Angle, Joint Angle, Length and Segment Linear), Quantity, Joint/Seg(s) and Component. Clicking the SELECT button will add the current selections to the data table and leave the menu open for additional selections while clicking the OK button will add the current selections and close the menu.

6. Click the OK button on the Data View Setup menu to graph the selected data.
7. Select the desired display options from the Graph Windows Toolbar. Available choices include Bar Graph, Line Graph, Spreadsheet and Single/Multiple Graph.
8. Select the PLAY button from the VCR control menu to animate the current selections.
9. The user may now save, analyze, and/or print the project.

LINEAR GRAPH:

Linear is selected to plot joint motion (displacement, velocity or acceleration) in the standard Cartesian coordinate system. An additional curve measure, Raw Position, may be selected for linear type curves. This measure represents the actual digitized position values prior to data smoothing. In the Cartesian system, motion is represented either by X, Y & Z coordinate components which are signed values with implicit direction, or by resultant "3D" magnitude which is an unsigned valued with no implicit direction. The coordinate system is the one selected for the "control points" used to calibrate the image space, and the units of measurement are those initially specified for this sequence.

The following steps are recommended for creating Linear plots.

1. Set the TYPE column to LINEAR.
2. Set the QUANTITY column to the desired parameter. Available choices are Raw Position, Displacement, Velocity and Acceleration.
3. Set the JOINT/SEGMENT #1 column to the desired joint. Available choices are determined by the Point ID's that were established in the Digitizing module.
4. Set the COMPONENT column to the desired parameter. Available choices are X, Y, Z and 3D (Magnitude).

5. Click the OK or SELECT button. NOTE: Clicking the SELECT button will add the selected data set(s) to the list of data sets in the grid without leaving the dialog box. This allows additional entries to be made to the grid. Select the OK button to enter the selected data set to the active data set display and close the current menu.
6. Select the OK button on the Data View Setup menu to display the graph in a new window.

7. Use the icons on the Graph Window tool bar to display the data in the desired format.

SEGMENT ANGLE GRAPH:

The digitized figure can be described as segments linked together at the joints and is basically a system of moving segments or links. Segment Angle is selected to plot the motion (displacement, velocity or acceleration) of an individual SEGMENT about one endpoint in the polar coordinate system. In this system, motion is represented by an angular component about the pole (segment endpoint) as viewed along one of the coordinate axis directions. Angular units are always the same (degrees) regardless of the linear units chosen for this sequence. Segment angles are selected from the list of segments for a project as determined by the joint connection table.

The following steps are recommended for creating Segment Angle plots.

1. Set the TYPE column to SEG ANGLE.
2. Set the QUANTITY column to the desired parameter. Available choices are Displacement, Velocity and Acceleration.
3. Set the JOINT/SEGMENT #1 column to the desired segment. Available choices are determined by the segments that were established in the Digitizing module.
4. Set the COMPONENT column to the desired parameter. Available choices are X, Y, and Z. For segment angle curves, this component represents the viewing axis. (Selecting Z would display the angle projection on the X-Y plane.)

5. Select the COMPLEMENT option to display the complement angle.
6. Click the OK or SELECT button. NOTE: Clicking the SELECT button will add the selected data set(s) to the list of data sets in the grid without leaving the dialog box. This allows additional entries to be made to the grid. Select the OK button to enter the selected data set to the active data set display and close the current menu.
7. Select the OK button on the Data View Setup menu to display the graph in a new window.

8. Use the icons on the Graph Window tool bar to display the data in the desired format.

JOINT ANGLE GRAPH:

Joint Angle is usually selected to plot the motion (displacement, velocity or acceleration) of one segment relative to another about the joint that they share in common. Motion is reported in the polar coordinate system as a relative angular component about the pole (joint) either as viewed along one of the coordinate axis direction, or as viewed along the perpendicular to the plane of the two segments. Angular units are always the same (degrees) regardless of the linear units chosen for this sequence. Joint angles are specified by selecting 2 segments from the segment list. In this way the angle between ANY two segments, not necessarily ones with a common joint, can be graphed.

The following steps are recommended for creating Joint Angle plots.

1. Set the TYPE column to JOINT ANGLE.
2. Set the QUANTITY column to the desired parameter. Available choices are Displacement, Velocity and Acceleration.
3. Set the JOINT/SEGMENT #1 column to the first desired segment. Available choices are determined by the segments that were established in the Digitizing module.
4. Set the JOINT/SEGMENT #2 column to the second desired segment. Available choices are determined by the segments that were established in the Digitizing module.

5. Set the COMPONENT column to the desired parameter. Available choices are X, Y, Z and 3D.
6. Select the COMPLEMENT option to display the complement angle.
7. Select the OK button on the Data View Setup menu to display the graph in a new window.
8. Use the icons on the Graph Window tool bar to display the data in the desired format.

LENGTH GRAPH:

Length is selected to plot the linear distance between two joints. The units of measurement are those initially specified for this sequence. Lengths are specified by selecting 2 joints from the joint list. In this manner, the length between ANY two joints, not necessarily ones with a common segment, can be measured and graphed.

The following steps are recommended for creating Length plots.

1. Set the TYPE column to LENGTH.
2. Set the JOINT/SEGMENT #1 column to the first desired joint. Available choices are determined by the Point ID's that were established in the Digitizing module.
3. Set the JOINT/SEGMENT #2 column to the second desired joint. Available choices are determined by the Point ID's that were established in the Digitizing module.
4. Click the OK or SELECT button. NOTE: Clicking the SELECT button will add the selected data set(s) to the list of data sets in the grid without leaving the dialog box. This allows additional entries to be made to the grid. Select the OK button to enter the selected data set to the active data set display and close the current menu.

5. Select the OK button on the Data View Setup menu to display the graph in a new window.
6. Use the icons on the Graph Window tool bar to display the data in the desired format.

SEGMENT LINEAR GRAPH:

Segment Linear is selected to plot the "linear" components of a segment. The difference between Linear and Segment Linear is that the segment has a mass and a joint does not. When the Segment Linear option is specified, three new items are listed in the Qty column. Linear quantities of Force, Energy and Power are of a point concentrated at the segmental center-of-mass with a mass equal to the segment mass. The units of measurement are those initially specified for this sequence. 

The quantities are defined as: Force = Mass x Acceleration (Nt or Lbs) Energy = 0.5 x Mass x Velocity x Velocity (Nt-m or Ft-Lbs) Power = Force x Velocity (Nt-m/s or Ft-Lb/s)

The following steps are recommended for creating Segment Linear plots.

1. Set the TYPE column to SEGMENT LINEAR.
2. Set the QUANTITY column to the desired parameter. Available choices are Displacement, Velocity, Acceleration, Force, Energy and Power.
3. Set the JOINT/SEGMENT #1 column to the desired segment. Available choices are determined by the Point ID's that were established in the Digitizing module.
4. Set the COMPONENT column to the desired parameter. Available choices are X, Y, Z and 3D (Magnitude). Note: Energy and Power are scalar quantities and have only a single 3D value.

5. Click the OK or SELECT button. NOTE: Clicking the SELECT button will add the selected data set(s) to the list of data sets in the grid without leaving the dialog box. This allows additional entries to be made to the grid. Select the OK button to enter the selected data set to the active data set display and close the current menu.
6. Select the OK button on the Data View Setup menu to display the graph in a new window.

NOTE: This step is optional for the full version of APAS software as these settings should be specified during the trimming process in the TRIM module.

7. Select the OK button on the Stick Figure View Setup menu to display the AVI file in the video window.
8. Select the PLAY button from the VCR control menu to animate the current selections.
9. The user may now save, analyze, and/or print the project.

VIDEO OPTIONS:

FIELD ORDER

A standard video picture is made up of odd and even lines across the screen. Television standards require these lines to be interlaced. This means only half of the lines are displayed in one field. The first (odd) set of lines is displayed in the first field while the second (even) set of lines is displayed in the second field. These two fields comprise a frame, which is a complete picture.
Depending on the hardware and software combinations used for recording and displaying the AVI files, it is possible for the order of the displayed fields to be reversed. For this reason, the Ariel APASView program provides the option to specify the order for displaying the AVI files.

If it appears that the images are "jerky" or are being displayed in a "zigzag" manner, the field order probably needs to be reversed. The field order is specified using the following steps.

1. Select the OPTIONS menu to display the list of video options. Left-click either Normal or Reverse in the FIELD ORDER section. The current selection is indicated by the black dot to the left of the option. NOTE: When this option is changed, it affects all other APAS software modules where the AVI file can be displayed (Capture, Digitize, Display, Vectors etc.)
2. Select OK to proceed and save changes or CANCEL to abort.

SEPARATE FIELDS

Older models of the APAS capture an analog video signal using a step capture process and a computer controlled VCR. When using the "step capture" mode, the software and VCR work in conjunction to capture only the field information from the video signal. Therefore, when using video captured from the "step capture" process, the field information is already separated and this setting should be set to NO.
Capturing digital video in real-time results in the entire frame being captured. The field information is obtained by separating the frame into the two respective fields. This is required when using digital video files and is automatically set to YES.

SPEED

The APAS is capable of digitizing from any of various video formats. These formats can be determined by a variety of factors including the type of camera used for video recording, the make and model of frame grabber as well as the selected frame rate for recording. When using the JVC digital camcorder in the high-speed mode, video images are split to either one-half or one-quarter of the original size. The user must indicate which speed and/or JVC mode was used for the video recording to allow the software to correctly separate the images during the digitizing process.
