Where are you? That is the question oâ€™ the day. With all of our mobile devices and wireless accessâ€¦we can now find each other easily (when we want to be found), but interestingly enough, we rarely know where the other person is. And how often are you not quite sure where you are? Wouldnâ€™t it be cool to have your very own Marauder’s Map? (Just in case you arenâ€™t up on your Harry Potter..the Marauder’s Map is a magic map that shows the location of everyone in Hogwarts School of Witchcraft & Wizardry in real time).
Reality check, Goodwitchâ€¦there isnâ€™t a real marauderâ€™s map!
Why, I beg to differ. Iâ€™ve experienced it myself!
Iâ€™ve been researching location sensing with handheld computers and discovered some delicious off-the-shelf solutions. My first round of testing was with the Ekahau Position Engine which uses WiFi signal strength to sniff out your location and map you to the map. So, Iâ€™ve literally watched the motions of my teammates on my very own Ekahau/Marauders Map! Our early results have given us accuracy to within 6 inches (at best) and 22 feet (at worst). Iâ€™m looking forward to the next round of fine tuning which I hope yields accuracy of 3 feet or better. Why in the world would I want to accurately know where someone is? So, I could provide information to you (if you want it) based on your current location.
- You are in a gallery in the museum and I can give you information on the works of art that are near you.
- Youâ€™ve wandered off from the rest of your group and wonder where they are & vice versa.
College Campus Examples:
- It is the first day of classes and you donâ€™t know where your next class is.
- You agreed to meet a friend on the west mall, but there is quite a crowd and you canâ€™t locate them.
So, what would you like to know from your location sensitive PDA or Laptop? Would you want location based information? Do you like the idea of being able to see where someone is or allowing others to see where you areâ€¦or is it all a little too â€œbig brotherâ€ for you?
