Demo for PlaySS, including Jemba Virtual Co-driver

This is a system to tie together a lot of different types of information for special stages on rallies without a big effort.
It links together the following information:

- A video recording along the stage
- Information about the vehicle movements when the recording is done
- GPS information
- Over all and stage maps for the event

The data is tied together and put into a data base system to enhance the possibility for different types of analysis.
It may be used by the race control, safety organization, and other officials as well as by the competitors. For competitors the option to get basic, very consistent pace notes, may be interesting. It may be of great interest for the public as well.
As most information about stages is gathered in a database together with video and tools to carry out measurements it is an efficient way to file a complete event. The access to information is extremely easy and fast so the system gives a powerful tool to compare events from different years in a lot of aspects.

Problems?

If video can not be seen you may need to install the codec for the type (AVI) of video files used. The Windows codec can be downloaded from here.

If the video doesn't run smoothly or the dynamic tulip or icons flicker, you may need to run your computer in a faster mode.
