3. SM2701 Theories of Interactivity – Class 02 Numerical representation Created from scratch on computers Converted from analog media (digitization) Think about how the animation and ca students work on their projects.
4. SM2701 Theories of Interactivity – Class 02 Numerical representation Created from scratch on computers Converted from analog media (digitization) Can we really tell?
11. SM2701 Theories of Interactivity – Class 02 Digitization Sampling - temporal Quantization - spatial

19. SM2701 Theories of Interactivity – Class 02 How can we compare analog and digital media?
20. SM2701 Theories of Interactivity – Class 02 Is old media equal to analog media? Half-tone in printing
35. SM2701 Theories of Interactivity – Class 02 Can visual media do the same?

37. SM2701 Theories of Interactivity – Class 02 Instruction Paintings By Yoko Ono, 1961 A + B PAINTING Cut out a circle on canvas A. Place a numeral figure, a roman letter, or a katakana on canvas B on an arbitrary point. Place canvas A on canvas B and hang them together. The figure on canvas B may show, may show partially, or may not show. You may use old paintings, photographs, etc. instead of blank canvases.

40. SM2701 Theories of Interactivity – Class 02 Is it a painting? void setup() { size(400,400); smooth(); noLoop(); } void draw() { background(0); ellipse(width/2,height/2,100,100); }
41. SM2701 Theories of Interactivity – Class 02 Is it a computer program? Can a computer program drawing a picture be a piece of artwork?
47. SM2701 Theories of Interactivity – Class 02 Modularity Object-oriented authoring software Structured programming practice
48. SM2701 Theories of Interactivity – Class 02 Modularity Object-oriented authoring software Structured programming practice How is it related to Automation and Variability?
49. SM2701 Theories of Interactivity – Class 02 Data and logic (algorithm) In computer programming, why do we need to separate clearly data and logic?
50. SM2701 Theories of Interactivity – Class 02 Data and logic (algorithm) In a typical blog or portal website, can you easily identify which is data and which is logic (control)? For example, the SCM web at http:// www.cityu.edu.hk/scm / or my personal blog at http:// www.bryanchung.net /
51. SM2701 Theories of Interactivity – Class 02 Data and logic (algorithm) How is this philosophy different from traditional art practices?
52. SM2701 Theories of Interactivity – Class 02 Database as metaphor of art Huge amount of media elements are stored in databases. Interactivity is achieved through various access paths to the data.

59. SM2701 Theories of Interactivity – Class 02 Discussion How should we approach to view these two films?
60. SM2701 Theories of Interactivity – Class 02 More examples Urban Feedback – London and Tokyo
62. SM2701 Theories of Interactivity – Class 02 Transcoding Try to remember the Letrism exercise a lot of you have done.
63. SM2701 Theories of Interactivity – Class 02 Transcoding Case 1: write a program to turn all the pixel information of a photo into sound with frequency corresponding to the brightness of the pixel. Case 2: write a program to capture the words typed by the participants. For each character, convert it into a colour pixels on the screen.
64. SM2701 Theories of Interactivity – Class 02 Transcoding How would you comment on these two great artworks?
