Differences in Internet Usage - Social Inequality and Informal Education

In the public debate the internet is regarded as a central resource for knowledge and information. Associated with this is the idea that everyone is able and even expected to serve himself or herself according to his or her own needs via this medium. Since more and more services are also delivered online the internet seems to allow its users to enjoy specific advantages in dealing with their everyday life. However, using the internet is based on a range of preconditions. New results of empirical and theoretical research indicate the rise of a social divide in this context. Within the internet, different ways of use can be identified alongside social inequalities. Boundaries of the "real life" are mirrored in the virtual space e.g. in terms of forms of communification and spaces for appropriation. These are not only shaped by invidual preferences but particularly by social structures and processes. In the context of the broader debate on education it is stated that formal educational structures are to be completed by arrangements which are structured in informal respectively nonformal ways. Particularly the internet is suggested to play an important role in this respect. However, the phenomenon of digital inequality points to limitations consolidated by effects of economic, social, and cultural ressources: Economical resources affect opportunities of access, priorities of everyday life shape respective intentions of internet use, social relationships have an impact on the support structures available and ways of appropriation reproduce a specific understanding of informal education ("informelle Bildung"). This produces an early stratification of opportunities especially for the subsequent generation and may lead to extensive inequalities regarding the distribution of advantages in terms of education. Thus the capacity of the virtual space in terms of participatory opportunities and democratic potentials raises concerns of major relevance with respect to social and educational policy. From the perspective of different disciplines involved in these issues it is essential to clarify this question in an empirical as well as in a theoretical way and to make it utilizable for a future-orientied practice. This article discusses central questions regarding young people's internet use and its implications for informal education and social service delivery on the basis of empirical findings. It introduces a methodological approach for this particular perspective and illustrates that the phenomena of digital divide and digital inequality are as much created by social processes as by technical issues.

Transfer of spatial knowledge from a virtual environment to reality: Impact of route complexity and subject’s strategy on the exploration mode

The use of virtual reality as tool in the area of spatial cognition raises the question of the quality of learning transfer from a virtual to a real environment. It is first necessary to determine with healthy subjects, the cognitive aids that improve the quality of transfer and the conditions required, especially since virtual reality can be used as effective tool in cognitive rehabilitation. The purpose of this study was to investigate the influence of the exploration mode of virtual environment (Passive vs. Active) according to Route complexity (Simple vs. Complex) on the quality of spatial knowledge transfer in three spatial tasks. Ninety subjects (45 men and 45 women) participated. Spatial learning was evaluated by Wayfinding, sketch-mapping and picture classification tasks in the context of the Bordeaux district. In the Wayfinding task, results indicated that active learning in a Virtual Environment (VE) increased the performances compared to the passive learning condition, irrespective of the route complexity factor. In the Sketch-mapping task, active learning in a VE helped the subjects to transfer their spatial knowledge from the VE to reality, but only when the route was complex. In the Picture classification task, active learning in a VE when the route was complex did not help the subjects to transfer their spatial knowledge. These results are explained in terms of knowledge levels and frame/strategy of reference [SW75, PL81, TH82].

Simulating Wind and Warmth in Virtual Reality: Conception, Realization and Evaluation for a CAVE Environment

Wind and warmth sensations proved to be able to enhance users' state of presence in Virtual Reality applications. Still, only few projects deal with their detailed effect on the user and general ways of implementing such stimuli. This work tries to fill this gap: After analyzing requirements for hardware and software concerning wind and warmth simulations, a hardware and also a software setup for the application in a CAVE environment is proposed. The setup is evaluated with regard to technical details and requirements, but also - in the form of a pilot study - in view of user experience and presence. Our setup proved to comply with the requirements and leads to satisfactory results. To our knowledge, the low cost simulation system (approx. 2200 Euro) presented here is one of the most extensive, most flexible and best evaluated systems for creating wind and warmth stimuli in CAVE-based VR applications.
