Ideal Process:

text input from phone–>http request–>get geocoding result–>send back to phone and mark in a canvas–>caculate diatance between markers–>play music when the distance is shorter than blablabla…

1.Geocoding:
Using google, it is simple to just sending a request by entering the address, output format(could be xml,kml,csv..etc.) and your map api key, as what I’ve done for Tisch:

http://maps.google.com/maps/geo?q=721+Broadway,+New%20York,+NY&output=csv&key=ABQIAAAANU1h1CcuvxsgKtU7UJFsahTjbm9Hu27GUmpzMwBxmcjvYN_wNRTP5AAdgJAXEVbtxzS1XeQSP4KhwQ

Here we choose csv format and it returns 4 numbers, which are:
status code, accuracy, latitude, and longitude.

accuracy represent how much you specify your address, if you specify the exact number with street, city, and state,
it is usually 8, if you only provide street name, the accuracy rating will be 6.
For final, we will only use latitude and longtitude.

2.Marker Manager: mark the point that has done geocoding in a canvas in cell phone.

3.Caculate the distance between each marker in the canvas in cell phone.

4.do something based on the distance.

Although it would be great to have a group of built subway station geocoded in the canvas already…

.To be continued.

There are not so many chances to hack objects , for the sake of breaking them into pieces,
except that it is for school use, seriously..
This semester I was first freaken out by the 18000 dollar IR camera that my teacher suggested me to buy,
and quickly accept the truth that hacking is the only way out..and it’s Fun!!~~:D

You may never notice, but as I looked for a IR source, there I got a little TV remote control to tear down,
and as I looked for developed nagative film as IR filter, they are all sitting in the garbage can up in 8th floor Tisch!!!
Plus I was acturally using a nail to tear my webcam :O

And this intresting web get my really excited~

A very little short break in Central park.in time for late fall.

I jumped back to google apis and found something interesting.
Openal: this might help in terms of audio and space.
http://www.openal.org/downloads.html

Google earth kml: About defining the relative and absolute positoin of specific object and read data to display it.
http://earth.google.com/kml/kml_21tutorial.html#iceland
http://earth.google.com/kml/kml_overview.html#placemarks

Plus a sweet python code for updating coordinate(longitude,latitude,aptitude) every 10 second..
sth.closer, at least visually satisfying

Also, about the famous google map & yahoo map,
here’s something to look into: since yahoo provides the service of geocoding, sounds slightly better..

Although, it seems to be a little bit old..

Everything’s turn off with my laptop, at least my blog’s barely alive

For my final project, I always wanted to do something related to music and distance(Maybe using GPS and bluetooth?)
It’s always a question whether I should build a fun game or something’s really useful.
I thought I wanna build a music game that allow a group of people to log in and enjoy playing sound like a life band when they are in the same space. But then it comes to something that is using similar concept, how about tracking several objects that you lost all the time, and use sound to point out the right diection? For example, there might be a menu that allow you to choose from:

1. a specifit position(such as subway stations) in map using GPS.
2. other people who connect their phone/device to GPS and allow you to track their location in real time.
3. somewhere you just walk by and wanna mark the position and come back later.

Therefore for example, I don’t have to check the map all the time and will know which way is the right way when I’m getting
close or when I just have to know whether the subway station is one block down south or two blocks down north, and where the uptown entrance is somewhere closer than I thought.

It’s gonna be useful for people who’s lazy enough to watch map all the time when they almost know where they are heading
and still hate to mistaken the direction.(especially when it’s a long avenue..)

ha, so ideally, here is the possible process:

1. user phone—>gps—>knows where the user is
2. user setting the target–>gps–>knows where the target is
3. caculate and update the distance of 1. and 2.
4. when the distance is less than 50 meter(not set yet, but should be within visual distance), your phone sing a song
of course it can sing all kind of song that tell the user how far away it is soon as it knows the distance..

Well, I have no idea if there’s any better way to do this, or simply how far I can do for now. But I hope it’s doable,
and I will start spending time. It would be really great to hear from any other voices:)

is annoying.

Well., I try not to complain about my cute little old IBM too much,
cause it might have some feeling and never listen to me any more.

I guess people changes,
I used to write paper that discuss how internet fake the truth of reality,
when once upon a time I believed living without computers makes life simple in a good way.
But recently I just realized how annoy it is to run everything slower..
I still enjoy those moments in central park though,
but knowing and expecting to go back to my laptop soon.
Now life with computer is more life reality.
How wierd..
well, celebrating for getting online again and have endless downloading…
