What DDES9902 covers
Nine chapters follow the current teaching sequence from reality-virtuality and embodied interaction through human performance, prototype testing, tracked input, situation awareness, evaluation, team pipelines, ethics and collaborative virtual environments.
Reality-Virtuality and Interaction Modes
Classify the setting, affordance and cue-action-feedback loopThe opening topic places immersive experiences on the reality-virtuality continuum and asks how people act within them.
- Reality-virtuality as a continuum of mediated and physical information
- Immersive systems as coordinated display, sensing, rules and feedback
- Affordances as relationships between user capability and environmental cues
- Interaction loops from discoverable cue through action to response
- Choice of input modality according to task, body and context
- Physical awareness and accessibility alternatives in mediated environments
Perception, Locomotion and Safety
Diagnose sensory conflict, rendering performance and safe movementImmersive safety depends on the relationship between display performance, visual motion, vestibular information and physical movement. The topic explains why a visually convincing scene can still produce discomfort when cues disagree or updates arrive late.
- Sensory conflict between visual motion and vestibular information
- Frame stability and latency as health and safety properties
- Continuous, snap-turn, teleport and room-scale locomotion trade-offs
- Physical boundaries, balance and collision risks
- Performance budgets that protect interaction response
- Comfort settings, stop controls and monitored evaluation
User Testing and Prototype Evidence
Choose fidelity, observe behaviour and document iterationA prototype is valuable when it lets someone attempt a meaningful interaction and exposes a design assumption.
- Prototype fidelity matched to the design uncertainty
- Moderated tests, cognitive walkthroughs and less intrusive observation
- Observable behaviour such as attempts, pauses, errors and recovery
- Separation of observation from interpretation
- Versioned design changes linked to user evidence
- Retesting comparable tasks to evaluate an iteration
Biometrics, Simulation and Visualisation
Limit signal interpretation and make representation serve a taskTracked gaze, facial movement and body pose can extend immersive interaction, but the signal a device records is not identical to the intention, attention or emotion a designer assigns to it.
- Eye, face and body tracking as sources of interaction signals
- Difference between measured behaviour and inferred user state
- Calibration, occlusion and individual variability
- Foveated rendering and gaze-assisted interaction
- Visualisation chosen for a defined analytical task
- Simulation boundaries, omissions and appropriate claims
Situation Awareness and Therapeutic VR
Balance perception, cognition, alerts and guarded exposureSituation awareness is built through perception of relevant elements, comprehension of their meaning and projection of what may happen next.
- Perception, comprehension and projection in situation awareness
- Cognitive load limits and the cost of competing cues
- Cognitive fit between representation and required operation
- Alert salience, meaning, escalation and recovery
- Training transfer and the risk of teaching unsafe habits
- Therapeutic exposure as a guarded application rather than a product claim
Evaluation, Fidelity and Compliance
Trace requirements to behaviour, acceptance and corrective actionEvaluation begins with a requirement, not with an impression of realism. A simulation should represent the cues, actions and consequences needed for the target decision while making deliberate simplifications visible.
- Observable requirements rather than broad claims of realism
- Physical, functional and psychological fidelity
- Task-critical cues and consequences in training simulations
- Requirement-to-test traceability
- Acceptance criteria and predefined corrective action
- Boundary between prototype performance and real-world competence
Design Pipelines and Iteration
Coordinate specialist roles through testable learning loopsImmersive projects combine interaction design, art, programming, sound, research, technical direction and production. A useful pipeline defines how decisions cross those roles and how evidence can reopen them.
- Specialist roles in immersive production teams
- Decision hand-offs across design, art, development and research
- Iteration as evidence changing the next version
- Anti-waterfall creative cycles with disciplined planning
- Minimum testable artefacts and risk-focused sprints
- Version history, ownership and review decisions
Ethics, Access and Societal Effects
Map stakeholders, power, mitigation and residual riskEthical immersive design considers people beyond the direct headset user. Bystanders, workers, participants who rely on access alternatives, institutions and wider communities can experience different benefits and burdens.
- Stakeholder mapping beyond the direct user
- Equitable access across body, sense, device and context
- Purpose limitation and minimisation for bodily data
- Consent, withdrawal and power in immersive research or use
- Bias, misrepresentation and error recovery
- Mitigation owners, review points and residual societal risk
Collaborative Virtual Environments
Support shared awareness, coordinated change and persistenceCollaborative virtual environments connect people through shared places, objects, communication channels and task rules.
- Social presence and awareness of people, focus and intent
- Shared object state, roles and editing authority
- Communication channels and turn-taking cues
- Conflict prevention, undo and recovery
- Persistent artefacts, activity history and re-entry
- Desktop and alternative routes into shared immersive work
It then examines the perceptual systems that make immersion possible and can also make it unsafe, including visual motion, vestibular information, frame performance, latency and locomotion.
Prototype testing provides the bridge from theory to design evidence: students choose a suitable level of fidelity, observe what users actually do, distinguish observations from interpretations and revise the experience with a documented reason.
Later topics extend that method to tracked inputs such as gaze and body movement, immersive visualisation, situational awareness, cognitive load, training fidelity and guarded therapeutic applications.
The second half of the course focuses on evaluating requirements, coordinating immersive production teams, working iteratively, designing for access, addressing ethical and societal effects, and supporting productive collaboration in shared virtual environments. Assessment is project-based. The official UNSW record publishes Interaction Reconceptualisation at 40% and Human-Centered Design Process at 60%, which total 100%.
The active Moodle shell provides task briefs, advice, submission boxes and development-material requirements. This guide does not reproduce those prompts. It provides original worked reasoning and practice so you can explain why an interaction suits its user and setting, how a prototype tests an uncertainty, what evidence supports a revision, and where safety, privacy, accessibility or fidelity limits the claim.
Worked example · free
Turn a user observation into a design iteration
- +1Record the behaviour before interpreting it: the user reached toward the tool, then stopped without selecting it.
- +1State the bounded diagnosis: the object suggested grasping, but the required trigger action was not discoverable.
- +1Revise the feedback chain: add hover feedback and a contextual controller hint after the first failed reach.
- +1Retest the same task and record whether selection occurs before the hint, preserving version and task conditions.

DDES9902 FAQ
What makes this immersive design course difficult?
The challenge is connecting several kinds of reasoning at once. A strong response must explain a human factor, translate it into an interaction decision, show evidence from a prototype or user test, and preserve safety, accessibility and ethical limits. Memorising definitions is not enough because the projects reward a traceable design process.
How is this immersive design course assessed?
The official UNSW record lists Interaction Reconceptualisation at 40% and Human-Centered Design Process at 60%. The current Moodle shell provides briefs, marking resources and separate submission areas for reports, demonstrations and development materials. Check each active task page because companion files can have different dates.
What should a prototype prove?
A prototype should answer a design question. Choose the lowest fidelity that allows the relevant behaviour to occur, state the uncertainty before testing, and record what users do. A polished build without a clear question can demonstrate effort while producing weak evidence for the next design decision.
How should user testing appear in the report?
Keep observation, interpretation and revision distinct. Record the task, version, participant instructions, observable actions and any intervention. Then explain the most plausible interpretation, acknowledge alternatives and connect a specific change to that evidence. Retesting the same behaviour makes the iteration easier to evaluate.
How do safety and accessibility affect immersive design?
They shape the interaction from the start. Rendering stability, locomotion, boundaries, sensory load and stop controls protect users from physical or perceptual harm. Equivalent input, output and participation routes help people with different bodies, senses, devices and contexts reach the same meaningful task outcome.
Are past papers available for this course?
The available course folder contains project briefs, advice, a marking workbook, weekly teaching resources and references, but no past exam paper or practice final. Use the official task briefs and marking materials to understand project evidence, and use original practice scenarios to rehearse design reasoning without implying an exam format.
Questions students ask in each DDES9902 chapter
- How is augmented reality different from virtual reality?
- Augmented reality keeps the physical environment available and adds digital information to it, while virtual reality replaces most of the immediate visual setting with a generated one. The distinction changes safety, alignment, input and attention requirements; it is not simply a difference in visual quality. Chapter 01 · Reality-Virtuality and Interaction Modes
- Why can low frame performance make VR unsafe?
- Unstable updates and delayed responses weaken the expected link between head movement and the visual scene. That mismatch can increase discomfort and make objects or boundaries harder to judge. Performance decisions therefore belong in the safety rationale, not only in a technical appendix. Chapter 02 · Perception, Locomotion and Safety
- How polished should my first prototype be?
- Only as polished as the current question requires. Use low fidelity for sequence, concept or label problems and higher fidelity for timing, embodiment, visual performance or safety. Extra detail can consume effort and introduce variables without making the evidence more useful. Chapter 03 · User Testing and Prototype Evidence
- Can gaze tracking tell whether someone is interested?
- It can show where the system estimates a person looked, under calibration and sampling limits. Interest is an interpretation that may also depend on confusion, task demands or distraction. Use gaze for a narrow interaction or research purpose and avoid treating it as a direct reading of mental state. Chapter 04 · Biometrics, Simulation and Visualisation
- Why can more information reduce situation awareness?
- Attention and working memory are limited. When many elements compete, a critical cue may be missed or its meaning may not be integrated with the wider situation. Organise information by task and urgency, keep context stable and reveal detail when it supports the next decision. Chapter 05 · Situation Awareness and Therapeutic VR
- Does higher visual realism mean higher training fidelity?
- Not necessarily. Visual resemblance is physical fidelity, while a training goal may depend more on correct control behaviour, consequences and decision pressure. A realistic scene can still teach the wrong sequence. Allocate detail to the cues required by the task and verify behaviour. Chapter 06 · Evaluation, Fidelity and Compliance
- Why does the course describe the creative cycle as anti-waterfall?
- Important information appears during making and user testing, so a fixed one-way sequence can preserve a weak concept. The alternative is not disorder. Teams plan short evidence loops, keep constraints visible and let observations change priorities, interactions or the problem frame. Chapter 07 · Design Pipelines and Iteration
- What makes an accessibility alternative equivalent?
- It should preserve the meaningful purpose of the experience, not merely offer any substitute. A desktop or seated route may use different controls, but it should still allow the participant to inspect, decide, learn or collaborate at a comparable level. Chapter 08 · Ethics, Access and Societal Effects
- Does avatar realism improve collaboration?
- It can support identity, orientation or nonverbal cues, but it can also consume performance, misrepresent expression and distract from the task. Use the minimum embodiment needed for coordination, then prioritise reliable shared objects, intent cues, permissions and recovery. Chapter 09 · Collaborative Virtual Environments
How to prepare for the assessments
Study DDES9902 by building a decision log rather than a stack of definitions. For each topic, write the human requirement, the interaction mechanism, the most serious failure mode, the evidence that could reveal it and the design response you would take.
Redraw the major relationships from memory: the reality-virtuality continuum, sensory conflict, the iteration cycle, situation-awareness layers, requirement traceability and the collaborative network. Then apply each drawing to your current prototype. Before testing, choose one uncertainty and the lowest sufficient fidelity. During testing, record actions, timing, errors, recovery and help before asking for opinions.
Afterward, separate observation from interpretation and identify an alternative explanation. Make one linked revision and preserve version evidence. Use the active Moodle brief and marking sheet to confirm deliverables, because summary week labels and companion submission pages can differ.
In the report, let screenshots and data serve an argument: every artefact should show what changed, why it changed and what remains unresolved. Protect participant privacy, cite third-party assets and make access alternatives part of the core design rather than an appendix.
