Dear BIOMECH-L readers,


I am a student studying mechanical engineering and currently researching
comfortbility of automobile seats. I am looking for video based motion
analysis systems, with video editing capabilities.
Its planned to record drivers in car seat movement with video cameras for
several hours. At the same time, I would like to record a seat interface
pressure, with a sensing mat (TEKSCAN).
Do You know of a software package, which automaticly recognizes those
sequences, which indicate a movement of the subject?
I would also like to record driving data, such as stiring, braking,
accelerating, indicating, ...etc. in order to find out, which of the
indicated movements are related to driving.
Could You give me any suggestions, how to synchronize the video signals, the
seat pressure data and the driving data?
MY AIM IS TO FILTER OUT ALL THE SEQUENCES WITH NO MOVEMENT AND MOVEMENT
BECAUSE OF DRIVING.

So far, I had the following thoughts, how to tackle the problem :
2 - 3 mini-DVCAMS, to record the testperson
1 camera records a LED, which flashes, when the seat pressure mat
indicates a change of the pressure pattern
mixing the video signals in a mixer (SONY), to compile the camera views to
an image, consisting of four splitted images (?)
Storing this image in MPEG-format on the harddrive of a notebook or
alternatively on digital video tape
analysing the video with "NOLDUS Observer":
- viewing the video with fastforwarding, flashing LED indicates the duration
of
a movement
- producing of a highlight video, including these marked scenes, where a
movement is recognized
- manually cutting of the scenes, where driving related movements are
indicated

Do You have a less tedious way of filtering between
a) in general movement and no movement
b) driving related movement and non-driving related movement

I would be very grateful of any suggestions or comments regarding above.I am
open for a totally different solution or a different approach, how to
realize the selection of movement data.

Thank You very much for your time and consideration in advance

Yasin
