The Daily Mirror recently put out a summer story on the risks of using SatNavs. While I would question the statistics and the reliability of the information, as it is probably based on a quick phone survey of 2000 people and then extrapolated in some unclear manner, I do think that we need to understand more about the tunnel vision that SatNav devices create in user’s mind.
The problem of showing a users only small section of reality without the full context is surely the right way to provide information in a short burst that does not risk them too much. While I still want to see some research on how long do users look at their SatNavs using an eye tracker (if anyone is willing to sponsor this – we’ve got the equipment!), I’m confident that there is solid reasoning behind the visualisation as it is now.
So, although this is suitable visualisation, we have an unintended consequence of tunnel vision view of the environment through which the user navigates. We are now starting to see some of the misshapes that occur due to this, and that is an area that requires more research and understanding.
