quote:The section, which deals with photographs or videos, says that static or near-static maps for the purpose of driving directions are acceptable. Near static is defined as being updated every few seconds.
Every current installed navigation system uses the car as a fixed point, and shows the map moving around it. NHTSA wants that changed so as to keep the map fixed. Even showing the position of the car moving on the map could be considered a dynamic image. The recommendation seems to suggest that the position of the car could only be updated every couple of seconds. Likewise, the map could be refreshed once the car has left the currently displayed area.
Huh...fortunately it's just a proposal at this point ;-)
I suspect not much study has been done to arrive at the above quoted recommendation. Those users who have experienced some of the earlier versions of navigation software, which in fact did not refresh map and/or car position continuously, could attest that the use of such system required more of the driver's visual attention to the display screen and also it required more time to think about the task of navigating than it does with the use of systems which use continuously updated moving map with the car icon pinned to one location.
