week4 - Download and view image

Click to see demo

the above link seems not working, still haven't figured out why, so here is a screenshot:

what this does is download Google's logo from Google's home page, darken the image by multiplying the RGB value of each pixel 0x777777.

comment of ChoRong's midterm idea

I was impressed by the idea of visulizing calendar in a map-like format. I am really curious and keeping thinking about what would it be like?

6. Integrated devices, modes, products

week 3 - Project Idea 3

Leave Sb A Gift

Hyeki described this mobile game to me, which is people search and find vitural items in physical space by having to physically getting the right position on map. The key technic is GPS. I like this idea, not neccessarily the game. I like playing the idea between vitural and physical and something outdoor.

So this inspired me have an idea of this application. It's so cool to leave someone a secret gift or anything somewhere in the city or anywhere on the earth! This thing is virtual, but you have to actually go to that place to get that thing someone else left for you. It could be on a bridge, it could be in a corner of city, it could be in the sea! Once you get the exact place, you will get the virtual object. It could be a message, it could be a web link where you have any online presence you want to give it to that person, or it could also be the next target!

week3 - Project Idea 2

Since our group (Hyeki, Shinyi and I) got a Nokia N95, I started to more think about some location based application/game.

Earth Graffiti

This project called MERIDIANS inspired me. The artist carried a handheld GPS (Global Positioning System) receiver to trace his movements by recording his position regularly along the journey. And then represented these data on map. The image below is one of a series, which all together is a quote "It is not down in any map; true places never are." See more images and the project here.

So I got some inspirations from this project. The app/game what i'm thinking about is, one by physically going from one place to another and another, can pinpoint his path on map. He can see the drawing on earth map in real time, so that he can determine where he goes next. Maybe he also can set the color and weight of stroke. The purpose for the user/player is to generate some interesting drawing. After the drawing, he can send the picture to web, where people can share what they draw and the stories during that process.

Or one can send those pin points(not entire drawing) to someone, with which the other person by physically following the path can reveal the drawing, over any long period of time he wants. Maybe someone want to say "i love you" to a person, or someone draws a little cake for a person's birthday gift. People can be very creative and imaginative of what they draw and what they do with it, also having a lot of fun.

Week3 - Canvas Responding Button Presses

I created this little app, where different sizes and degrees of color grey of square appear responding to certain button being pressed. For example, if button 1 is pressed, a square that is 1/10 of screen width wide and 1/10 of screen height high and very close to total black will appear. if button 9 is pressed, a square that is 9/10 of screen width wide and 9/10 of screen height high and less close to total black will appear.

Screen shots:
1. button 6 is pressed


2. button 4 is pressed

3. button 9 is pressed:
