The Stability

The predictive value and the reliability of evaluations made in immersive projection environments are limited when compared to the real world. As in other applications of numerical simulations, the acceptance of such techniques does not only depend on the stability of the methods, but also on the quality and credibility of the results obtained. In this paper, we investigate the predictive value of virtual reality and virtual environments when used for engineering assessment tasks. We examine the ergonomics evaluation of a vehicle interior, which is a complex activity relying heavily on know-how gained from personal experience, and compare performance in a VE with performance in the real world. If one assumes that within complex engineering processes certain types of work will be performed by more or less the same personnel, one can infer that a fairly consistent base of experience-based knowledge exists. Under such premises and if evaluations are conducted as comparisons within the VE, we believe that the reliability of the assessments is suitable for conceptual design work. Despite a number of unanswered questions at this time we believe this study leads to a better understanding of what determines the reliability of results obtained in virtual environments, thus making it useful for optimizing virtual prototyping processes and better utilization of the potential of VR and VEs in company work processes.

Minimal Effort

Multi-User Virtual Environments (MUVEs) have been found to be engaging and provide an environment in which the elements of discovery, exploration and concept testing, fundamental to the field of science, can be experienced. Furthermore, MUVEs accommodate lifelike experiences with the benefit of the situated and distributed nature of cognition; they also provide virtual worlds to simulate the conditions that are not doable or practicable under real world circumstances making them very relevant to many other fields of study such as history, geography and foreign language learning. However, constructing MUVEs can be expensive and time consuming depending on the platform considered. Therefore, providing the most appropriate platform that requires minimal effort, cost and time will make MUVE deployment in the classroom faster and more viable. In this chapter, the authors provide a comparative study of prominent existing platforms for MUVEs that can be used to identify the right balance of functionality, flexibility, effort and cost for a given educational and technical context. A number of metrics are identified, described and used to enable the comparison. Platform assessment was done in four main metric groups: communication and interaction, characters, features and education. Communication and interaction metrics are used to assess how the communication and interaction is done within the examined platform. Character metrics are employed to measure avatar and agent affordances. Features metrics are defined to compare what the platform offers in terms of technology. Lastly, education metrics are used to identify the value of the associated platform for educational purposes.

Field Report

This chapter reports on the transformation of a classical seminar paper presentation course into a completely virtual classroom experience beginning with the planning phase and ending with the students’ final evaluations. The virtual course included homework lessons and online examinations. Findings on what is actually needed to accomplish this goal are provided, while demonstrating what barriers arose in the process and how they were solved. The course topic was the psychological impact of violent video games and included learning in virtual environments. An up-to-date internet multiplayer game was applied encompassing comprehensive communication features and non-violent interactivity of the players with each other as well as the environment. Beyond the classical paper presentations held via voice chat, accompanying missions for the game were designed to demonstrate the crux of the matter in a playful style. This included both real world procedures well known to the participants such as map reading and vehicle driving as well as rather uncommon ones like flying a helicopter and complex missions with different roles needed like emergency rescue or organized mass killing. This way, participants were able to compare their known real world experiences with virtual ones and evaluate the relevant psychological theories in a comprehensive virtual world. Further, participants could reflect on learning in general and especially on the learning of aggression in virtual environments in a depth that would hardly have been possible without experiencing the interactive phenomena by themselves.

Eye Fixations

This paper describes a set of experiments investigating the interaction between the location of eye fixations and the detection of unexpected motion while driving. Both psychophysical and real-world observations indicate that there are differences between the upper and lower visual fields with respect to driving. We began with psychophysical experiments to test whether the detection of unexpected motion Is inherently different in the upper and lower visual fields. No difference was found. However, when texture was added to the driving surface, a large difference was found, possibly due to optokinetic nystagmus stimulated by the texture. These results were confirmed in a driving simulator, and their implications for head-up displays (HUDs) explored. We found that the same upper/lower field asymmetry could be found with digital HUDs but not with analog HUDs. These experiments illustrate how virtual environment technology can connect knowledge from psychophysical experimentation to more realistic situations.
