:: WORKSHOP ::

[assignment 1 presentation: basically my idea came from last year, and i futher develpoed it. it is called || Digiti ||. which is a combine of digital technology and graffiti, which uses a LED, webcam, a programme by Director extra TrackThemColors or Webcam Xtra and a projector. this project is going to read, reconize and draw lines when i move the LED light in front of a little semi-transparent panel, which is also place in front of the webcam, then the webcam will track the movement of the LED and convert it into lines, finally, the projector will project the line drawing back onto the panel, or any other buildings or landmarks. after the presentation, i was recommanded to use Processing, so the next step will be start playing with Processing, a free and open source environment.]











































:: INSPIRATION/RΣSΣARCH ::

[i did a deeper research on Dan O'Sullivan and Tom Igoe's Physical Computing. beside of the information about micro-controllers and how to build your own circuit to connect your computer and the BX-24, i also found something related to my project. which is || video tracking || and || video by pixel ||. i found it really useful, because i know more about how a webcam work and how the computer see objects under different light conditions. basically, the idea of tracking motion on a computer using a video camera is still not fully perfect, because it is talking about construct vision for a computer by writing a programme. however, the human brain is able to analysis colors, edges, depth under different light sources. for example, we recognize a red danger sign in the daytime and at night, it is the same sign for us. but, for a computer, it will recognize it as a different objects, because the color is changed due to the light conditions.]
