What Is Presence?

… has produced mediated experiences that seem increasingly natural, intuitive, comfortable, easy, automatic, because the technology seems increasingly less like technology.

What Is Presence?

• Perceptual illusion of nonmediation

• Real time during media use

• Not a disorder or abnormal

• Property of media user

• Result of media form and content, media user characteristics and media context/environment

Why Is Presence Important?

• It’s ‘central’ – relates to many fields and endeavors

• It will be increasingly common

• It has many potential effects

Causes of PresenceForm variablesNumber of sensory outputsConsistency of sensory outputsVisual display characteristics

Image quality** Image size **** Viewing distance **** Proportion of visual field **MotionColorDimensionalitySubjective camera techniques

Causes of Presence

Aural presentation characteristicsQuality (frequency range, dynamic range, signal to noise ratio)Spatialization (dimensionality)Volume

InteractivityNumber of inputs from user the medium accepts and responds toNumber and type of characteristics of mediated presentation/experience user can modify

Causes of PresenceInteractivity (cont’d)

Range or amount of change possible in each characteristic user can modifyDegree of correspondence between type of user input and type of medium responseSpeed of medium response (lag time)

Obtrusiveness of mediumLive versus recorded or constructed experienceNumber of people

Causes of PresenceContent variablesSocial realismUse of media conventions (formula plot/dialogue, etc.)Nature of task or activity

AmbiguityDifficultyEmotionality

Causes of PresenceMedia user variablesWillingness to suspend disbeliefKnowledge of and prior experience with the mediumPersonality typeInterestsPreferred representational system (visual, auditory, or kinesthetic) Cognitive style Propensity to "screen" stimuliMood before/during/after media useAge, Gender

Effects of PresencePhysiologicalArousalVection and simulation sickness (dizziness, eyestrain, disorientation, dysphoria, standing and walking unsteadiness, nausea)Automatic responses (e.g., flinching, ducking, grasping chair)Reduced eye-hand coordination FlashbacksIllusory sensations (e.g., of climbing and turning)Reduced motor control

Presence Research • Goals

– Identify and manipulate causes

– Understand and develop cohesive theory of cognitive, affective, and behavioral processes of telepresenc

– Identify, measure and manipulate consequences of telepresence

Big Picture Questions

• How to maximize usefulness of telepresence?

• What forms do people want and fear?

• Where will technology evolution take us? (utopia vs. dystopia)

• How to deal with ethical challenges?
