Agenda
  • Introduction
  • An old concept with new technologies, applied in
    the following sections
  • Text
  • Audio
  • Graphics
  • Animation
  • Video/Movie
  • Interactivity
  • Conclusion

Introduction (1)
  • An evolution of the digital technologies in last
    two decades initiates a great demand and
    opportunity to revamp the old media.
  • From digitalizing and recovering analog contents
    to using advanced digital technologies to retake
    the old titles of film/movie, all those
    activities driven the demand and development of
    sophisticated digital technologies.
  • According to Moores Law, the complexity of
    integrated circuits, with respect to minimum
    component cost, doubles every 24 months,
    implies the momentum of using and developing new
    digital technologies will keep non-stop.

Introduction (2)
  • E.g. 1 Mission Impossible (1966-1973 1996-2006)

Introduction (3)
  • E.g. 2 King Kong (1933, 1976 2005)

Digital effects by Weta Digital Ltd.

Introduction (4)
  • E.g. 3 ???? (1967 1986)

Introduction (5)
  • E.g. 4 Super Mario (1985-2007)

Text
  • From traditional script writing to nowadays
    collaborative computing. It is a great change
    about the mode of creation.
  • In the analysis and promotion of web-technology,
    the phrase Web 2.0 refers to a perceived second
    generation of web-based communities and hosted
    services such as social-networking sites, wikis
    and folksonomies which aim to facilitate
    collaboration and sharing between users.
  • The term became popular following the first
    O'Reilly Media Web 2.0 conference in 2004, and
    has since become widely used.

Audio (1)
  • From Phonograph record (Gramophone record),
    Cassette tape, Laserdisc (LD), Sony Minidisc Data
    (MD), Compact Disc (CD) to MP3 ? From analog
    storage to digital storage.

10
Audio (2)
  • From analog, low-fidelity digital to
    high-fidelity digital audio system. Same title of
    song from same singer can be published twice or
    even more times, just with different quality
    (upgrade from 16 Bits to 24 Bits of AD
    digitalization) or medium.

11
Audio (3)
12
Graphics (1)
  • From traditional Chinese painting to the advanced
    Computer-generated imagery (CGI), all are the
    combinations of tools, techniques and design.
  • Can we applied advanced computer graphics
    technologies to manipulate the traditional
    Chinese art works?

13
Graphics (2)
  • Animating Chinese Landscape Paintings
  • Ref. http//www.cse.ust.hk/cpegnel/ACLP/thesis.h
    tml
  • Digital Chinese Arts
  • Ref. http//www.cse.ust.hk/cpegnel/VCB/

14
Graphics (3)
  • Computer Vision
  • Computer vision is the science and technology of
    machines that see.
  • As a scientific discipline, computer vision is
    concerned with the theory and technology for
    building artificial systems that obtain
    information from images. The image data can take
    many forms, such as a video sequence, views from
    multiple cameras, or multi-dimensional data from
    a medical scanner.

15
Graphics (4)
  • As a technological discipline, computer vision
    seeks to apply the theories and models of
    computer vision to the construction of computer
    vision systems. Examples of applications of
    computer vision systems include systems for
  • Controlling processes (e.g. an industrial robot
    or an autonomous vehicle).
  • Detecting events (e.g. for visual surveillance)
  • Organizing information (e.g. for indexing
    databases of images and image sequences),
  • Modeling objects or environments (e.g. industrial
    inspection, medical image analysis or
    topographical modeling),
  • Interaction (e.g. as the input to a device for
    computer-human interaction).

Graphics (5)
17
Animation (1)
  • CMU, Virtual reception Roboception (by 3D
    character and animation).

18
Animation (2)
  • Japan First Virtual Idol DK96 (by 3D character
    and animation).

19
Animation (3)
  • Virtual Fitting

Animation (5)
  • Smart Ambience Therapy (SAT) by Prof. Horace Ip
    (CityU)

http//aimtech.cityu.edu.hk/sat/
22
Animation (6)
  • Playmotion

23
Video/Movie (1)
  • From the analog Standard Definition (SD) to
    digital High Definition (HD).
  • From the analog 35mm film to digital cinema with
    2K 4K resolution (2K and 4K refer to images
    with 2048 and 4096 horizontal pixel resolution).
  • Any changes with the concept of Television and
    Film/Movie?
  • Some new terms were coined, such as Interactive
    TV or 4D Movie.

24
Video/Movie (2)
  • Multi-camera (Camera Array)

25
Interactivity (1)
  • Digital Entertainment adopted of most advanced 3D
    graphics, Artificial Intelligence (AI) and ICT
    technologies.
  • The evolution of computer graphics from 2D to 3D
    make the development of new game titles with
    traditional characters become possible.
  • Certain very famous game characters have been
    published in different titles by using different
    technologies over 20 years.
  • Sonic the Hedgehog (1991 2005)
  • Super Mario (1985 2007)
  • Pac Man (1982 2006)

26
Interactivity (2)
  • Besides, the technologies of the controller also
    make great influence to the development of the
    game titles.

27
Conclusion
  • It is no matter old or new concept, applying of
    new technologies with old concept can be a new
    trend of the digital revolution.
  • Digital technology innovation not only relies on
    the development of hardware and software
    technologies, but also the contents.
  • Design make a critical step to drive the
    development of Apply an old concept with new
    technologies
