Document >Course Outline
This course intends to allow students to study advanced three-dimensional virtual environments.
These environments pervade our life, from the movies we watch, the games we play and the way we learn and socially interact.
The course will focus on usability and HCI aspects of these environments, not on the technology use to develop and build them.

Document >Course Outline
• Computer Graphics / Virtual Environment Theory• Graphics Rendering Pipeline• Transformations/Rendering• Polygon / Parametric Representation
Document >Computer Graphics Theory
Graphics Rendering Pipeline : Conversion of a scene into an image.
Document >Computer Graphics Theory
Transformations / Rendering : 2D and 3D Matrix Transformations
Document >Computer Graphics Theory
Polygon / Parametric Representation : Lines and Curves
Document >Computer Graphics Theory
Wireframe to Raster Image : Rendering
Document >Course Outline
• Graphical Realism• Multi-modal Representations• Viewpoint / Perspective / Resolution / Lighting
Document >Graphical Realism
Levels of Realism : Abstract and Realistic Representation (Uncanny Valley)
Document >Graphical Realism
A sophisticated level of realism, containing a high level of detail is often necessary since modern audiences have high levels of graphical literacy.
Document >Graphical Realism
Combining abstract and realistic representations to enforce a message can be effective, however, testing must be undertaken to ensure that the audience are getting the correct message.
Document >Multi-Modal Presentation
A multi modal approach (combining high resolution, three-dimensional virtual environments with photographs, plans and textual information) can be more successful than a single mode approach.
Document >Multi-Modal Presentation
There is convergence towards the ubiquitous mobile device. Delivery to portable devices is essential for most new media.
Document >Viewpoint / Perspective
The viewpoint is crucial - First Person (Egocentric) vs Third Person (Exocentric).
Document >Course Outline
• Model Simulation • Object Behaviour• Accuracy / Precision
Document >Simulation
It should never be forgotten that a virtual simulation, is by its very definition a ‘simulation’ of reality.
Document >Simulation : Object Behaviour
Object behaviour must be programmed : Animation or interaction.
Document >Simulation Accuracy / Precision
Precision and accuracy depends on the simulation context.
Document >Course Outline
• Interaction Metaphors• Visual / Aural Sensory Input• Active vs. Passive Interaction• Feedback Mechanisms• Navigation in Virtual Worlds• Hardware (3D Worlds)
Document >Visual / Aural Sensory Input
The integration of real-world audio soundtracks with a visual media can have a major impact on the level of engagement of the viewer, potentially affecting their understanding and interpretation of the material viewed.
Document >Active vs. Passive Learning
Interactive software resources encourage their users to be active participants by forcing them to make decisions throughout the simulation.
Document >Feedback Mechanisms
It is important that developers do not underestimate the value of spending time providing feedback to the audience.
Document >Environment Navigation
The graphics are often is not as important as the navigation and interaction ability.
Document >Hardware
The graphics are often is not as important as the navigation and interaction ability.
Document >Course Outline
• Narrative Structure• Linear / Non-Linear Narratives
Document >Narrative Structure
Most viewers are used to linear narratives and may struggle to keep following specific narrative threads with such a non-linear approach
Document >Narrative Structure
New mechanisms may be needed to allow users to interact and explore multi-thread narratives.
Document >Course Outline
• Testing / Evaluation in 3D worlds
Document >Testing
Surprisingly many systems are thrown out into the real world without adequate testing.
One needs to know if the message is getting across.
