Effects of noise upon human information processing

Studies of noise effects upon human information processing are described which investigated whether or not effects of noise upon performance are dependent upon specific characteristics of noise stimulation and their interaction with task conditions. The difficulty of predicting noise effects was emphasized. Arousal theory was considered to have explanatory value in interpreting the findings of all the studies. Performance under noise was found to involve a psychophysiological cost, measured by vasoconstriction response, with the degree of response cost being related to scores on a noise annoyance sensitivity scale. Noise sensitive subjects showed a greater autonomic response under noise stimulation

Learning in a Mixed Reality System in the Context of ‚Industrie 4.0‘

This contribution in the field of innovative approaches to training and education in technical subjects focuses on the potential of modern teaching and learning environments. The contribution is based on a theoretical introduction to Mixed Reality Systems and virtual teaching and learning systems, and as such provides an overview of current research regarding modern learning environments. In particular, it takes a close look at motivational effects in the context of web-based learning structures, human-object interactions, gamification and immersion. The article discusses both technical, user-relevant and pedagogical aspects as well as suggestions for further research in the context of Ausbildung 4.0.Keywords: Industry 4.0, Vocational Training 4.0, Mixed Reality System, virtual learning AcknowledgementThe author would like to thank the ChinaScholarshipCouncil(CSC) for the financial support (No. 201406030091)

Exploring context-sensitive collaborative augmented reality applications

In smart spaces limited amount of physical resources are available. Also, system should be able to offer relevant information according to user’s personal preferences. At the same time smart environments could serve many users with same requirement of relevancy and operate on limited resources. Sometimes it may not be possible to share resource in a way that respects all users without compromising collaboration. This thesis is focused on solving the problem of shared resource from the perspective of augmented reality. Selected standpoint is on mobile collaborative augmented reality and context-awareness. A small user study has been arranged as part of thesis to bring out information about user’s thoughts and emotions while using a simple prototype application. In addition, a small literature review about main concepts is conducted. There is a short analysis of some collaborative augmented reality applications presented based on recent literature. Results of the thesis show that even with small experiments it is possible to discover new information from users. Results also provide tentative answers to presented research questions. Main findings are that users have high expectations towards context-awareness and augmented reality technologies. They also expect applications to offer relevant, validated and also surprising information in each situation. This thesis has some evidence about suitability of augmented reality in context-aware applications that are targeted to support human-to human collaboration. With augmented reality it is possible to offer individual standpoints for users while they are inspecting limited, shared resources. Endorsement of user’s ability to monitor their environment is one challenge in large smart environments. Finally, software engineer can take user’s expectations into account when designing context-aware systems for smart environments. Also, developer could implement system that takes advantage of different human sensory modalities

GMonE: a complete approach to cloud monitoring

The inherent complexity of modern cloud infrastructures has created the need for innovative monitoring approaches, as state-of-the-art solutions used for other large-scale environments do not address specific cloud features. Although cloud monitoring is nowadays an active research field, a comprehensive study covering all its aspects has not been presented yet. This paper provides a deep insight into cloud monitoring. It proposes a unified cloud monitoring taxonomy, based on which it defines a layered cloud monitoring architecture. To illustrate it, we have implemented GMonE, a general-purpose cloud monitoring tool which covers all aspects of cloud monitoring by specifically addressing the needs of modern cloud infrastructures. Furthermore, we have evaluated the performance, scalability and overhead of GMonE with Yahoo Cloud Serving Benchmark (YCSB), by using the OpenNebula cloud middleware on the Grid’5000 experimental testbed. The results of this evaluation demonstrate the benefits of our approach, surpassing the monitoring performance and capabilities of cloud monitoring alternatives such as those present in state-of-the-art systems such as Amazon EC2 and OpenNebula

The development of sensory products to stimulate children with learning problems (LP)

Thesis (M. Tech.) - Central University of Technology, Free State, 2009Children with Learning Problems (LP) are mostly identified in the primary grades. Early intervention is desirable to remediate LP. One strategy is to use visual aids as a cue during an intervention strategy. A visual aid can be tactile and can appeal to the child’s senses, such as hearing and touch. Three main cornerstones which influence Sensory Product Development (SPD) were identified. These are design factors such as illustrations, colour, and book themes, the senses of the children and supporting factors which include therapeutic practices and cultural sensitivity. It is envisaged that if these three cornerstones are integrated into a sensory product such as a book, that it will be able to stimulate a child with LP through play, touch and sound. The aim of the study is the development of a qualitative tool that can be used to asses sensory products and the development of a sensory product that are tested for the specific target group. The sensory product was designed according to the guidelines that were identified in a literature review. This qualitative tool includes the various cornerstones and serves as a checklist that teachers and therapists can use to evaluate a sensory product to establish its suitability for a child with LP. The second article in this study recorded the responses from children with LP towards the sensory product and recommendations for the improvement of the sensory product

From Centralized interactive tabletops to Distributed surfaces: the Tangiget concept

International audienceAfter having outlined the uses of new technologies such as smartphones, touch-screen tablets, and laptops, this article presents the TangiSense interactive tabletop, equipped with RFID technology tagged on tangible objects, as a new paradigm of interaction for ambient intelligence. Within its framework, this article aims to distribute surfaces (tables) interacting mainly with tangible objects. Leads for interactive surface distribution such as interactive tables are given. The article proposes to describe some tangible objects, which are the interaction supports; these are called Tangigets. They are defined according to an augmented Presentation-Abstraction-Control structure to take the tangibility element into account. Six categories of Tangigets are also proposed, which are tangible objects, and the supports of distributed collaboration. To validate the Tangiget concept and its use on the TangiSense tabletop, illustrations in centralized and distributed configurations are proposed. A first evaluation is also presented. To conclude, the article presents the directions under consideration for our future research
