What you will need is a datasource with the following infos :
* track geometry id
* track geometry (one geometry per line track part)
* track id
* timestamp for this geometry
* Person id

Put all your informations in the same data source. Better with a database 
(spatialite / postgis).

Then you can filter on the person id to limit the display to only selected 
people. You can also use that info to to some symbolizing.

Then use the time manager plugin to be able to replay the data and display 
according to the timestamp.
