About 15 or more years ago...
I was almost always the first to arrive for any appointment, and usually more than 15 minutes early. And often I have to wait for more than 45 minutes for my friends to arrive. Waiting is no enjoyment, especially alone and in the days where mobile phones are unheard of and pagers are only just created and are meant more for businessmen. What about public phones? Well, if your friend is already 15 minutes late, and you are still able to get him at home, I'm not sure if it's to congratulate you on having contacted him or having such a latecomer as a friend.
Anyway, during those long waits, I thought that it would be good if there's some means to find out if the friend is indeed on his way. No, I'm not thinking about mobile phones. I'm thinking of a watch-like device which somehow calculates the distance between him and me. And it will provide a sense of how fast he will be arriving.
Ahh... riding on that, another application of it will be to enable my mum to know if I'm really on my way home, and perhaps with an estimate of how soon that will be (assuming I'm already on my way home).
Then also, travelling to an unknown place, if this device can somehow lock itself to my eventual destination, I will somehow get there eventually as long as the distance between my current location and destination decreases.
