Læringsmål:The objectives are to introduce the students to the physical, perceptual, and computational perspectives of sensing stimuli. Sensing stimuli are the essential data in a multimedia system. They may either be sensed by the computer through cameras, microphones, mouse, etc. or they may be presented by the computer for a human observer via a screen, head-mounted display, loud
speaker, force feedback devices etc. 
Fagligt indhold:In order to provide the students the basic knowledge for
understanding and building a multimedia system, the course
covers the following disciplines:


Physics: Sensing stimuli are physical observables: photons, air pressure variations, forces,
etc. The course will provide only the very basic concepts necessary for understanding sensing
stimuli.


Psychophysics: The human sensory system transforms the physical sensing stimuli into neural
activity. In order to represent sensing stimuli digitally, the student must understand which of
the physical properties are captured and transmitted to the brain by the human sensory system.
The course will provide superficial knowledge of the human visual system and human auditory
system, and an even briefer introduction to human skin senses, sense of balance and chemical
senses (smell and taste).


Computer Science: The computer science part of the course, which is the bulk of the course,
falls in 5 parts.
<ol type=1>

  • Digital representation of sensing stimuli: analog to digital conversion, data structures.
  • Processing of sensing stimuli: a very brief introduction to signal processing, image analysis, computer vision, computer graphics.
  • Transmission of sensing stimuli: coding, compression, protocols.
  • Synchronization. When several stimuli are
    processed in parallel the must be presented synchronized. As an example, the mouth must be synchronized with the speech. This topic include multitasking, semafors, synchronization.
  • Presentation of sensing stimuli: digital to analog conversion.
     
    • Læringsaktiviteter:

    Morning lectures and afternoon exercises with reports. 

    Eksamensform og -beskrivelse:X. experimental examination form (7-scale; external exam), 13-skala, Intern censur

    Weekly exercises must be approved.

    Oral examination, can be combined with examination of 4 week project if the subject of this falls within the area of multimedia systems.
