Navigation by calories – New insights useful for next generation navigation systems?

In a German science news ticker I saw an article a inspiring post reporting an experiment on orientation in relation to food. It describes an experiment where men and women were asked to visit a set of market stalls to taste food and afterwards they are asked where the stall was.

The to me surprising result was that women performed better than men (which is to my knowledge not often the case in typical orientation experiments) and that independent of gender the amount of calories that are contained in the tasted food influenced the performance. Basically if there are more calories in the tasted food people could remember better where it was. I have had no change yet to read the original paper (Joshua New, Max M. Krasnow, Danielle Truxaw und Steven J.C. Gaulin. Spatial adaptations for plant foraging: women excel and calories count, August 2007, Royal society publishing, and my assessment is only based on the post in the newsticker.

This makes me think about future navigation systems and in particular landmark based navigation. What landmarks are appropriate to use (e.g. places where you get rich food) and how much this is gender dependent (e.g. the route for men is explained by car-dealers and computer shops whereas for women by references to shoe shops – is this political correct?).

Apropos: landmark based navigation. There is an interesting short paper that was at last years UIST conference that looks into this issue in the context of personalized routes:
Patel, K., Chen, M. Y., Smith,
I., and Landay, J. A. 2006. Personalizing routes. In Proceedings of the 19th Annual ACM Symposium on User interface Software and Technology (Montreux, Switzerland, October 15 – 18, 2006). UIST ’06. ACM Press, New York, NY, 187-190. DOI=

Perhaps this ideas could be useful for a future navigation system…
