I want to make a suggestion for a new feature for my GO navigation device, though it would probably be applicable to any navigation device. I provide 3 different cases where the feature would be helpful.
- When, for example, I find that my route is blocked because of a mudslide or whatever, I would like to avoid having the device nag me for the next hour about turning around at the next opportunity. One way to do this would be to have a pick alternate route function, which could also be done as a voice command.
- Sometimes, I simply miss the turn, and then sometimes the device simply picks an alternate route instead of bugging me to turn around. I'm in the process of finding a way to turn around to get back on track, and my device is now presenting a different route, without so much as informing me, much less asking me. I have landed in this confusing situation several times. If there were an explicit pick alternate route command, then the automatic re-routing could be suppressed, allowing the user to decide whether he wants a new route, or find a way to get back on track.
- The third way this function could be helpful is when multiple routes are presented. It may well be that there is a way to select which route I want, but I haven't figured that out yet; I'm only a computer engineer. With a pick alternate route command, it would be intuitively obvious to the most casual observer how to select the desired route.
All of these things have happened to me multiple times, and they are all annoying. When I'm driving in a strange new situation, perhaps with traffic and time pressure, the last thing I need is hassles from my navigation device. With one new command, the human interface could be improved all around.
