Multiple points

Groundman

I would like to see multiple point analysis, other than that its pretty nifty.

Great start; very handy and easy to implement in or out of the classroom.. WHAT IT NEEDS: *****Derive acceleration graphs from velocity graphs.... Easy programing fix **Export files directly to drop box, right now you have to email it out then import them into dropbox from your email, **Also export the data in an excel or csv file for other uses would be nice.. It would be nice to see: and perfect if *A little bit harder to understand mathematically but still easy to program, be able to not only rotate the origin for a tilted camera but be able to show the plane that is of interest incase you are filming something that's not directly perpendicular to the camera... Thanks a lot! Good start!

This is a great app

I am a physics teacher, and this app is amazing. The best way to show it in the classroom is with (surprise) vernier's logger pro software. Record the video on the iphone and then send it to your computer. Then use logger pro on your computer and show it on the LCD. I am even able to avoid mac/pc issues when I use my school's pc's. The controls are a bit touchy when using the analysis tools on the iphone, but it just takes getting used to it.

Missing one thing

Cogleyjp

This is great, but I would like to see acceleration too. Or a table to go with the graphs so I can get more precise numbers to calculate the acceleration.

All work and all play ;)

Here are some suggestions: * enable users to easily save graphs--separate or combined--in PNG to camera roll. Screenshot just doesn't cut it. * include data table, too. * provide vector/Bezier curve for easy motion tracking. Eyeballing is OK right now but less accurate; plus, it would save a lot of time to use vector instead of manually dragging the crosshair * multiple analysis points Keep up the good work !

Very good, almost perfect!

This is very useful for me as an animation student, especially for tracking one of the animation principles: Arc. I am having fun doing this. For the most, I can see the timing and spacing even though is not accurate or detail. Thank you for making this app! I could give this 5 stars, if only: 1. Theres an option to use frames per second instead (fps) 2. The app can detect, how many frames per second the video was recorded. 3. Tap and slide option to forward the video every frame 4. I wish I can change the size of the dots or the tracker.

Needs curve fit

tkb409

Recording and finding points works very well, but without the ability to curve fit you cannot do any analysis on the iPad. A linear fit at the very least is needed to use this in any sort of meaningful way on its own. If you need to use a computer, you might as well just use this as a video camera without the app.

Over a year since last update!

When this app first came out it had some interesting functionality, but more potential than performance. Despite many good recommendations for enhancement by other reviewers (ex. Acceleration vs. time) the app has stayed stagnant. I'm beginning to wonder if this app was only released as bait to use logger pro since it has such limited functionality using iOS. It's almost a pedagogical crime to not take much better advantage of the incredible potential of this app. For shame Vernier.

Easy to use

I tried this app in class with my students today. I demo'd it quickly, then had them video a ball being tossed straight up and look at the graphs. I was amazed at how quickly they caught on and the quality of the graphs they got. It only took them about 10 minutes. Now that I know it's pretty quick, we can analyze many different types of motion. It is limited by the quality of the video, faster things tend to get blurred. There is the ability to zoom in on objects moving slower to get a more accurate positioning of them at various time intervals. I found with slower moving objects, it was better to skip ahead an equal number of frames. I only wish it had the ability to find the slope of the graphs, maybe it does and I didn't find it.
