provides the use with a greater sense of presence Immediacy of Control Appropriate and apparent consequences of actions add to a sense of presence Anticipation The ability to anticipate or predict the environment increases sense presence Mode of Control The more closely the manner of interaction relates to what is expected for the environment the greater the sense of presence Physical Environment Modifiability The ability to modify the environment increases presence Figure 5: Factors of Presence Sensory Factors Affecting Immersion (Witmer,1998) Sensory Modality Visual senses have the highest impact on the feeling of presence with other senses like sound, and touch contributing Environmental Richness The greater the sensory information in each modality, the more a sense of presences is achieved Multimodal Presentation The more completely all senses are engaged the greater the sense of presence Consistency of Multimodal Information If the experience of each sense agrees with others it increases the sense of presence 18 Degree of Movement Perception The perception of movement increases the sense of presence Active Search Control of focus within the environment can increase sense of presence Figure 6: Sensory Factors Affecting Immersion Distraction Factors Affecting Immersion (Witmer,1998) Isolation Isolation from reality as in a head mounted display, leads to a greater sense of presence Selective Attention The audience’s ability to focus or ignore distraction impacts the sense of presence Interface Awareness The less the interface is noticeable, the greater the sense of presence Figure 7: Distraction Factors Affecting Immersion Realism Factors Affecting Immersion (Witmer,1998) Scene realism presence increases as realism increases Consistency of information with the objective world, the more consistent the environment is to the real world the easier presence is Meaningfulness of experience the more the experience becomes meaningful to the audience, the more presence increases Separation anxiety / disorientation the more present the audience feels in the environment the more they should experience disorientation upon returning to reality Figure 8: Realism Factors Affecting Immersion Another chief investigator in presence and immersion is Slater has influenced many researchers in immersive virtual environments Written at a time when virtual environments were just becoming a possibility, the authors identify “presence” as being the central goal and defining feature of virtual reality 19 S la te r a na lyze d the conce pts of imme rs ion a nd pre s e

pre s e nce be ing he a vily influe nce d by the fa ctors of imme rs ion “Immersion is a description of a technology and describes the extent to which the computer displays are capable of delivering an inclusive, extensive, surrounding and vivid illusion of reality to the senses of a human participant Inclusive (I) indicates the extent to which physical reality is shut out Extensive (E) indicates the range of sensory modalities accommodated Surrounding (S) indicates the extent to which this virtual reality is panoramic rather than limited to a narrow field Vivid (V) indicates the resolution, fidelity, and variety of energy simulated within a modality (for example, the visual and color resolution) Vividness is concerned with the richness, information content, resolution and quality of the displays.” (Slater, 1997) Slater described another factor of immersion as the ability of the virtual environment to match the user's real-world body movements inside the virtual environment A selfrepresentation of the user body as part of and the center of the virtual environment “Matching requires that there is match between the participant's proprioceptive feedback about body movements, and the information generated on the displays A turn of the head should result in a corresponding change to the visual display, and, for example, to the auditory displays so that sound direction is invariant to the orientation of the head Matching requires body 20 tracking, at least head tracking, but generally the greater the degree of body mapping, the greater the extent to which the movements of the body can be accurately reproduced.” (Slater, 1997) Slater categorizes each dimensions of immersion with an associated scale, indicating the extent of its realization The measure of matching includes the latency between action by the user and the response by the virtual environment The final dimension of immersion described by the paper is plot, the degree that the virtual environment presents a self-contained storyline that is self-contained, has its own dynamic unfolding of events Presence is contrasted with immersion as being the perfect state of consciousness where the mind believes it is there within the virtual environment “Immersion can be an objective and quantifiable description of what any particular system does provide Presence is a state of consciousness, the (psychological) sense of being in the virtual environment.” (Slater, 1997) These factors of immersion and their role in presence within a virtual environment have been frequently used and cited by researchers, making them a sort of standard measurement tool to analyze presence in virtual environment technology (Slater, 1997) Developing a VR Instruction Environment My re s e a rch a nd pra ctice

Hardware Selection Analysis Consumer Access How easily will consumers access the equipment and instructional content This includes the cost, operating system, and how easily it can be purchased? Manufacturer Support How well will the VR equipment manufacturer provide replacement parts, software updates, application development utility? Ecosystem Longevity How long after purchase will the manufacturer improve and maintain the development environment, hardware, and how long will applications developed for the system be useable before deprecation? Quality of user Experience How well will the head mounted display, audio systems, controls, menus, and ease of use provide a quality experience? Ability to deliver factors of effective Instruction How well will the system deliver Immersion, Suspension of Disbelief, and Flow? Figure 10: My Hardware Selection Analysis There were three main VR ecosystems that promised to have the longevity and quality needed as this project started; the Oculus Rift, the HTC Vive, and Google Cardboard that became Google Dream Each VR platform has advantages and disadvantages from a development standpoint Google Cardboard became Google Dream since 2015 when this project was started, it may eventually have the quality of Oculus and Vive but as this project started, the user experience was poor, limited to Android mobile devices requiring large video assets to be downloaded or streamed, making it difficult to deliver high resolution video to the application 23 Google products come with a lot of ris k for de ve lope rs be ca us e of Google ’s philos ophy of cons ta nt cha nge a nd the

training process menu in the form of a screen that allows the user to choose the training module with a title and a thumbnail for each scenario The process menu appears after completion of each training module allowing the user to progress to the next module or go back to any of the previously completed modules Tutorial timeline control in the form of a menu of and start buttons for the user to control their progress through the tutorials The tutorial plays a 360° video clip that goes through each step of the instruction modules After each step is played the video pauses and triggers a formative question If the user chooses the correct answer the training progresses to the next step If the user selects the wrong answer the training replays the last step of the training module
