Formelle forudsætninger:Previoius completion or simultaneous enrollment in
\"Basics of Programming\" from ITU or equivalent 
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.







The student passing the course will be capable of programming a very simple networked multi media system taking into account the priciples of








- human sensing








- digital representations of media








- compression of media








- multi tasking and mutual exclusion








- networking








The course introduces the student to these various







scientific and technological fields, but the student will







not be taught in sufficient depth in these areas to master







the disciplines. This must be acheaved by subsequent course and project work. 
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.















Computer Science: The computer science part 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, scenegraph representation and interactivity
    with a reference to VRML, javascript, and java.







  • 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 mandatory weekly reports. 

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

    Oral examination with preparation, and with access to the course
    material and notes.
    It is allowed to bring one page A4 prepared during the preparation time,
    into the
    examination room.

    The duration of the examination is approx. 30 minutes.
    Weekly exercises must be approved (pass/fail) at the time of the last lecture.

    If the subject of the 4 weeks project falls within the area of this course, the examination of the project and the course is combined.

    Separate grading for the course and the project.
