Emerging Communication: Studies in New Technologies and Practices in Communication | Year: 2012

The convergence between telecommunication, virtual reality and artificial intelligence technologies resulted in a dramatical increase and modification of the opportunities to experience the physical and social world. Their diffusion and integration into multi-user and multi-agent virtual worlds highlighted the relevance of addressing from a common psychological perspective the domain of communication and the domain of presence. New theoretical and practical questions are emerging, in the double intent to explain phenomena at the interplay between mind and technology and to design effective technological applications. This chapter has the goal to start an exploration of the links and reciprocal contributions between communication and presence, analyzed at theoretical, methodological and applicative level. © 2006 The authors.

Developments in computational techniques including clinical decision support systems, information processing, wireless communication and data mining hold new premises in Personal Health Systems. Pervasive Healthcare system architecture finds today an effective application and represents in perspective a real technological breakthrough promoting a paradigm shift from diagnosis and treatment of patients based on symptoms to diagnosis and treatment based on risk assessment. Such architectures must be able to collect and manage a large quantity of data supporting the physicians in their decision process through a continuous pervasive remote monitoring model aimed to enhance the understanding of the dynamic disease evolution and personal risk. In this work an automatic simple, compact, wireless, personalized and cost efficient pervasive architecture for the evaluation of the stress state of individual subjects suitable for prolonged stress monitoring during normal activity is described. A novel integrated processing approach based on an autoregressive model, artificial neural networks and fuzzy logic modeling allows stress conditions to be automatically identified with a mobile setting analysing features of the electrocardiographic signals and human motion. The performances of the reported architecture were assessed in terms of classification of stress conditions. © 2011 Elsevier B.V. All rights reserved.

Wayfinding ability has a high adaptive value, allowing humans to efficiently explore an environment in order to have a goal-oriented activity. This is done thanks to the capacity of individuals to actively acquire knowledge during interaction. Recently, different studies examined the wayfinding performances of older adults in Virtual Reality. While these studies underlined a greater difficulty with the wayfinding task in the elderly subjects, the effects of age on specific aspects of navigational tasks are less well specified. More, a recent study (Konishi & Bohbot, 2013) suggested that older people who use spatial navigational strategies (navigation is achieved by orientating oneself in relation to an allocentic landmark map) in their everyday lives may have increased gray matter in the hippocampus and enhance their probability of healthy and successful aging. To evaluate this hypothesis we tested 176 subjects (from 20 to 89 years old) in wayfinding ability by using an interactive computer-based evaluation tool-the VR Maze spatial task-that requires the translation of the allocentric spatial knowledge to the corresponding egocentric one and its organization to perform a goal directed wayfinding. More, the study explored the relationships of these abilites with traditional paper and pencil measures of memory, executive and attentive functions. Data show how some aspects of spatial ability impairment are not clearly detectable using classical tests, whereas they become evident using the VR Maze spatial task. This difference is even more marked in the wayfinding ability evaluation of the elderly population. Finally, the VR Maze spatial task appears to be correlated with classical neuropsychological tests. © 2014 The authors and IOS Press. All rights reserved.

The relationship between interactive media and stress has gained wide interest in the mental health area. In our research, we found that interactive experiences helped people manage their stress. By combining different techniques, which may produce more significant outcomes than single-strategy programs, we developed a stress management protocol to increase self-awareness, to control and relax oneself, induce positive emotions, and substitute negative emotions. Our stress management protocol was tested in a controlled study comparing three interactive experiences (virtual reality [VR], video, and audio). Results showed the efficacy of all three interactive experiences in inducing positive emotions and integrating different approaches to manage stress. In particular, VR showed better improvements related to the psycho-physiological changes. Implications of the results for worldwide healthcare services will be discussed. © 2012 Mary Ann Liebert, Inc.

For many of us, obesity is the outcome of an energy imbalance: more energy input than expenditure. However, our waistlines are growing in spite of the huge amount of diets and fat-free/low-calorie products available to cope with this issue. Even when we are able to reduce our waistlines, maintaining the new size is very difficult: in the year after the end of a nutritional and/or behavioral treatment obese persons typically regain from 30% to 50% of their initial losses. A possible strategy for improving the treatment of obesity is the use of advanced information technologies. In the past, different technologies (internet, virtual reality, mobile phones) have shown promising effects in producing a healthy lifestyle in obese patients. Here we suggest that a new technological paradigm - Interreality - that integrates assessment and treatment within a hybrid experiential environment - including both virtual and real worlds - has the potential to improve the clinical outcome of obesity treatments. The potential advantages offered by this approach are: (a) an extended sense of presence: Interreality uses advanced simulations (virtual experiences) to transform health guidelines and provisions in experiences; (b) an extended sense of community: Interreality uses virtual communities to provide users with targeted - but also anonymous, if required - social support in both real and virtual worlds; (c) real-time feedback between physical and virtual worlds: Interreality uses bio and activity sensors and devices (smartphones) both to track in real time the behavior/health status of the user, and to provide targeted suggestions and guidelines. This paper describes in detail the different technologies involved in the Interreality vision. In order to illustrate the concept of Interreality in practice, a clinical scenario is also presented and discussed: Daniela, a 35-year-old fast-food worker with obesity problems. © Riva et al.
