“…Spatial presence is considered to be an experience that only occurs during exposure to a medium, and the model is based on processes of perception and cognition. Higher forms of experience can be constructed on these foundations [8]. Therefore, the MEC model considers spatial presence, attention allocation and the construction of a spatial situation as key concepts for the emergence of presence.…”

The concept of “presence” as a measure of ecological validity in driving simulators

et al. 2015

This pilot study aims to find a way to measure 'presence' as a proxy for ecological validity in driving simulators. The underlying assumption is that a person experiencing a strong sense of presence in the virtual environment will react as if it were real. We measure 'presence' through the 'attention' given to the driving task. We hypothesize that the greater the attention given to the primary driving task, the more the subject will experience spatial presence. 'Attention' was varied by adding a second task and oncoming traffic; we then analyzed behavioral measures of driving performance and subjective 'presence'. The main result is a lack of congruence between subjective and behavioral measures. Although behavioral differences were observed between the various experimental conditions, there was no significant difference in subjective measures of presence. One explanation for this result could be that in all experimental conditions the driving activity did not require high-level cognitive processes, and was instead based on bottom-up attentional processes. Many of the processes involved in driving seem to be automatic, and this study argues for the concomitant use of subjective measures (such as questionnaires) and objective measures to assess presence in driving simulators. Furthermore, the development of a sensitive measure of presence seems to require more challenging scenarios in terms of controlled attention, cognitive involvement and more specifically, the emotions induced by the media. Participants are clearly aware that they are not exposed to any physical danger when using the simulator and the problem of their motivation must be taken into consideration. Another major problem is to establish the extent to which they are absorbed in the simulated driving task. A significant challenge for future research is the emotional validity of driving.

“…Plusieurs sortes d'habiletés sont sollicitées: l'orientation dans l'environnement, le choix de la trajectoire, le respect de cette trajectoire et la reconnaissance de la destination (Benyon et Hôôk 1997;Benyon 2000). À cela s'ajoute l'habileté de juger de la pertinence du point d'arrivée, sous forme d'un processus circulaire allant de l'éva-luation de la pertinence à la signification, et de la signification au jugement de pertinence (Chen et Czerwinski 1997;Dillon 2000 (Darken et al 1998;Fastrez 1999). Ces connaissances sont regroupées dans la structure mentale de l'individu et constituent un savoir plus général, le savoir spatial ou connaissance spatiale* dont l'acquisition est rendue possible par la conceptualisation mentale de l'espace dans sa globalité.…”

“…Tout au long du processus de navigation, l'individu, grâce à une habileté intuitive commune, se visualise et se repositionne constamment au sein de l'espace parcouru. Cette vision égocentrique lui sert de gouvernail pour naviguer tout en maintenant le cap sur sa destination (Darken et al 1998 (Chen 1998;Chen et al 2000) et auxquels l'usager fera ultérieurement référence.

L’évolution rapide des systèmes, leur complexité grandissante et la propagation des nouvelles technologies de l’information à tous les paliers de la société et dans diverses applications de la vie quotidienne posent un défi de taille aux spécialistes du design des systèmes informatiques. Ils ne peuvent plus compter sur des modèles génériques (Dillon et Watson 1996; Chen 2000) et assumer qu’une formation standardisée saura pallier les faiblesses de tous les profils d’utilisateurs (Ford 2000; Ford et Chen 2000). C’est ce qui explique, au moins en partie, la prolifération d’études portant sur les différences individuelles. Nous avons voulu explorer l’impact qu’a eu l’évolution de la notion d’hypertexte vers le concept d’espace virtuel sur l’étude de l’orientation spatiale et des comportements navigationnels.À partir d’une revue de la littérature des principaux écrits parus depuis 1997, nous présentons une analyse en trois parties : la première tente de cerner les rapports entre les individus et les nouveaux environnements électroniques et présente les concepts principaux. La deuxième partie dégage les caractéristiques méthodologiques des expérimentations passées en revue et examine les facteurs susceptibles d’influencer les comportements et l’usage des hypermédias. La troisième partie de l’analyse dresse le bilan théorique de ces recherches et souligne la complexité des problèmes soulevés.The rapid development of systems, their increasing complexity, the propagation of new information technologies to all levels of society and their varied applications to daily life present an important challenge to the specialists who develop computer systems. They can no longer rely on the generic models (Dillon and Watson, 1996; Chen, 2000) and presume that standard training can answer the shortcomings of all user profiles (Ford, 2000; Ford and Chen 2000). This partially explains the spate of studies focusing on individual differences. In this article, we explore the impact of the evolution of hypertext on the concept of virtual space and the study of spatial orientation and "navigational" behaviours.Using a review of the literature published since 1997 as a starting point, we present an analysis in three parts. The first part describes the relationship between individuals and new electronic environments and introduces the principal concepts. The second part identifies the methodological characteristics of past experiments and examines the factors likely to influence behaviours and the use of hypermedia. The third part of the analysis summarises the theory supporting the research and underscores the complexity of the issues.La evolución rápida de los sistemas, su complejidad creciente y la propagación de nuevas tecnologías de información a todos niveles de la sociedad y en diversas aplicaciones de la vida cotidiana presenta un desafío considerable a los especialistas en diseños de sistemas informáticos, que no pueden contar más con modelos genéricos (Dillon y Watson, 1996; Chen, 2000) ni asumir que una capacitación estandardizada ...

Abstract-Extended range telepresence allows a human user to intuitively teleoperate a mobile robot through arbitrarily large remote environments by natural walking. In order to give the user the possibility to navigate the robot through an arbitrarily large remote environments, while his own environment is of limited size, Motion Compression is used. The Motion Compression framework provides a nonlinear transformation between the user's path and the robot's path, which preserves path length and turning angles. There is, however, a difference in path curvature, which is minimized in order to guarantee a high degree of immersion.A major drawback of the current system is its inability to deal with non-convex time-variant environments or environments shared by multiple users. This paper presents a systematic approach to extending Motion Compression to non-convex environments. This solution will then be used to cover the multi-user case.
