Design 950 and 993 Autumn 2004

Current state: Canine Lameness Learning Module. (It currently only needs text and sound added - all movies are done).

Tasks done this quarter:

  1. Mostly, I continued to render video movies for insertion into the learning module.
  2. I entered this quarter with a computer that wasn't functioning quite right. I couldn't stick with Windows 2000 because it was giving me blue screens and locking up on me a lot. This is the operating system that I had been doing all my work on. I had my data stored across 4 160 Gigabyte hard drives. The main Windows 2000 drive became disfunctional after I added Easy CD/DVD creator 6 on it. It would not boot. I added Easy CD/DVD Creator 6 over break in order to back up my Gigabytes upon Gigabytes of data with my husbands DVD writer. I edited the registry and got it to boot normally again, but then I was dealing with lock ups and consistent blue screens on shut down. I did several different installs of Windows XP before getting a stable one. I had to try several different hard drive arrangements until I found a configuration on the EIDE channels that would accept the old Windows 2000 hard drives and boot from the new Windows XP hard drive. The hard drives had my data on it for my thesis project. So, the work had to be done.

  3. After install of Premiere Pro onto Windows XP, I lost my Quicktime (.mov) movie exporter. I needed to export the movies into .mov in order to bring them into Sorenson Squeeze for compressing for the internet. So, once I had Win XP, I edited the video first in Premiere Pro 7, exported as .avi. Then I brought the .avi files into Premiere 6 and re-rendered the movies as .mov. Then, I rerendered them again to compress them in Sorenson Squeeze. Just one extra step in the process.

  4. I tried to come up with button that would play flash movies backwards, but did not succeed. I tried using a tutorial I found on Flashkit.com. The tutorial is at: http://www.flashkit.com/tutorials/Interactivity/Other/Making_M-Eddie_Ca-52/index.php
    The code I used on a "play backwards" button was:

    on (press) {
    Begin Tell Target ("/rewind");
    Go to and Play (2);
    End Tell Target;
    End On;
    }

    On (Release) {
    gotoAndPlay (_currentframe +1);
    Begin Tell Target ("/rewind");
    gotoAndStop (1);
    End Tell Target;
    End On;
    }

    For the rewind engine movie clip symbol I used the following code:
    On frame one:
    stop ();

    On frame two:
    Begin Tell Target ("/");
    gotoAndStop (_currentframe -1);
    End Tell Target;

    On frame three:
    If (/:_currentframe = 1);
    Begin Tell Target ("/");
    gotoAndPlay (_totalframes -1);
    End Tell Target;
    End If;
    gotoAndPlay (2);

  5. I found a way of action scripting the "next frame" button that would skip several frames with one click. This was for the quarter speed movies. When rendered, Premiere duplicated frames in order to expand the timeline. The original jump to next frames button did not work that well for these movies because sometimes the next frame was the exact same as the previous frame. When user testing it myself, I became annoyed with the fact that I had to keep clicking the jump to "next frame" button many many times to get past the duplicate frames. So, I fixed the problem in all 9 quarter speed movies. The code that worked on the "next frame" button on CCLR Trot Video Frontal, for example, looked like this:

    on (release) {
    gotoAndStop(_currentframe -15);
    }

    The code that worked on the "previous frame" button looked like this:

    on (release) {
    gotoAndStop(_currentframe -19);
    }

  6. I met with Jon several times to go over text. I also read from two different orthopedic textbooks to come up with the text. When we were viewing the Flash learning module on the Imacs in the Veterinary Hospital 's student computer lab, we found that after about 1 hour of viewing the flash movies, the computer refused to load anymore movies. This was similar to what happened to me last quarter when I tested various multimedia on these Imacs. They loose memory after about one hour and refuse to load things correctly. I think they are storing too much in RAM. I've also been told by the system administrator that there is a power supply issue for the computer laboratory. If you move to another machine and do a fresh log on, you can bring up the learning module and view the movies that wouldn't load on the first computer that had been running for about an hour. I think I'm going to have to distribute the learning module on CD-ROM for this reason. The text is now being reviewed by Jon. After he gives it to me, I'll change the current text that is in the module. Here is the link to the new text I sent to Jon for review. It is a 26 page MS Word file (.doc).

  7. I worked on typing some of the text into the arrays in Flash. I found out that in order to get returns, or spaces between lines of text in the arrays, you just have to keep adding spaces and then publishing the movie to see if the text lands where you want it to. It is kind of guess work or trial and error.

  8. I went back to one flash motion capture movie and added text to show the phases of the gait cycle see Motion Capture Normal Walking Side View. I also went back into the Video Cranial Cruciate Ligament Rupture Walking movie in order to add arrows every time I saw the dog miss putting weight on her injured leg.

  9. I did a lot of bug checking on the learning module. Checking and fixing any broken links in the main flash file. Some of the frontal and posterior views I combined, on the video. I had to alter links to accommodate for no CCLR video of frontal and posterior walking.

  10. I created 3 versions of quizzes for the students. I originally did not know whether to have separate mocap and video quizzes or a combination quiz. I will scrap the existing quizzes and create 2 versions of a new quiz. As per our discussion on 12-07-04, I'll create one with 5 mocap followed by 5 video and then the second with the 5 video first and the 5 mocap examples second. The quizzes are linked to on my home page. http://www.accad.osu.edu/~hcaprett under my picture on the left.

  11. I created a survey to guage what they thought was helpful about mocap and video. It is intended to assess whether they preferred one to the other, or both together. I also have usability questions in it about the interface. I will delete the 3 rd page of the survey that asks them to compare VRML, Mocap, Video, Sequential Photographs, and Footfall Patterns. The survey is linked on my home page under my picture in the left column. http://www.accad.osu.edu/~hcaprett.
