I was wondering, what could be the best software (freeweare) available for individual tracking. I want to continuously track the distance that a certain individual inside an arena is, with regards to a specific spot / stimuli.
There is the R function "distm" in the "geosphere" package which computes the total distance based on a matrix of locations. You basically just need to update your matrix of locations and run the function, which will return you the total distance covered by the individual.
