Due to advances in treatment and people's living longer, chronic diseases are becoming more common among our population. This is a leading contributor to the increasing burden on our current healthcare system. To reduce this burden and sufficiently meet the needs of this growing segment of the population, healthcare organizations must encourage the elderly to take a more active role in caring for their own health and well-being. Technology may offer a solution to this shortcoming. "Positive Technology" focuses on the use of technology for improving the quality of our personal experience, and it suggests specific strategies for modifying/improving each of the different dimensions involved - Emotional Quality (affect regulation); Engagement/Actualization (presence and flow); Connectdness (collective intentions and networked flow) -and for generating motivation and engagement in the process. "Transformative Technology" are technologically-mediated experiences that support positive, enduring transformation of the self-world. The transformative content is delivered through a set of experiential affordances, which are stimuli designed to elicit emotional and cognitive involvement in the designed experience: (i) emotional affordances; (ii) epistemic affordances. The paper discusses discuss the possible role of positive and transormative technologies for healthy living and active ageing by presenting different practical applications of this approach recently developed by our team.

Virtual Reality (VR) is increasingly being used in combination with psycho-physiological measures to improve assessment of distress in mental health research and therapy. However, the analysis and interpretation of multiple physiological measures is time consuming and requires specific skills, which are not available to most clinicians. To address this issue, we designed and developed a Decision Support System (DSS) for automatic classification of stress levels during exposure to VR environments. The DSS integrates different biosensor data (ECG, breathing rate, EEG) and behavioral data (body gestures correlated with stress), following a training process in which self-rated and clinical-rated stress levels are used as ground truth. Detected stress events for each VR session are reported to the therapist as an aggregated value (ranging from 0 to 1) and graphically displayed on a diagram accessible by the therapist through a web-based interface.

Unilateral Spatial Neglect (USN) is normally assessed with paper-And-pencil tests. Virtual reality can be an effective neuropsychological tool for a more ecological and functional assessment and rehabilitation of neglect. We developed a 3D Virtual Reality platform-NeuroVirtual 3D-for the assessment and rehabilitation of cognitive deficits, in particular for USN. Within the virtual environments it is possible to interact with virtual objects and execute specific exercises using a Microsoft Kinect. Through the analysis of different grasping tasks it is possible to evaluate in an ecological way the patients' ability to find and handle objects in both sides of the virtual space.

Different studies, including longitudinal studies, suggest a link between body dissatisfaction, unhealthful weight-control behaviors and obesity in both male and female adolescents. Here we suggest that body dissatisfaction in obese adolescents may be driven by an allocentric negative body image that is no more updated by contrasting egocentric representations driven by perception. In other words, subjects are locked to an allocentric negative representation of their body (allocentric lock hypothesis-http://dx.doi.org/10.1016/j.mehy.2011.10.039) that their sensory inputs are no more able to update even after the dramatic body changes following a successful diet. More, the possible role of virtual reality in the prevention and treatment of obesity in adolescence is presented and discussed. © 2013 The authors and IOS Press.

Awake surgery can be highly stressful for patients. In fact, being awake, patients could perceive that the environmental demands are taxing or exceed their adaptive abilities. We proposed the use of Virtual Reality as a functional and effective tool for a new class of clinical applications aimed at helping patients to cope with these specific stressful situations. Using coping skills that have been learnt during the virtual experience, patients can reduce their psychological stress and improve their collaboration and - in general - the outcome of the intervention.

In this study we consider neurophysiological aspects for the assessment of stress-related disorders. EEG Alpha Asymmetry could represent an effective method to be used in the virtual environment. Nonetheless, new protocols need to be defined. In this study herein, we present two methods and a case study.© 2012 The authors and IOS Press. All rights reserved.

Psychological Stress occurs when an individual perceives that environmental demands tax or exceed his or her adaptive capacity. Following this view, that underlines the role of the situated experience of the patient in experiencing a stressor, the European Union funded Interstress project (http://www.interstress. eu) is exploring the possible use of the virtual simulation technology offered by SecondLife (http://www.secondlife.com) to administer a stress management experiential training. The structure of the environment and the contents of the course are described and discussed. © 2012 The authors and IOS Press. All rights reserved.

In this paper we introduce a new ubiquitous computing paradigm for behavioral health care: "Interreality". Interreality integrates assessment and treatment within a hybrid environment, that creates a bridge between the physical and virtual worlds. Our claim is that bridging virtual experiences (fully controlled by the therapist, used to learn coping skills and emotional regulation) with real experiences (allowing both the identification of any critical stressors and the assessment of what has been learned) using advanced technologies (virtual worlds, advanced sensors and PDA/mobile phones) may improve existing psychological treatment. To illustrate the proposed concept, a clinical scenario is also presented and discussed: Daniela, a 40 years old teacher, with a mother affected by Alzheimer's disease

At MMVR 2007 we presented NeuroVR (http://www.neurovr.org) a free virtual reality platform based on open-source software. The software allows non-expert users to adapt the content of 14 pre-designed virtual environments to the specific needs of the clinical or experimental setting. Following the feedbacks of the 2000 users who downloaded the first versions (1 and 1.5), we developed a new version--NeuroVR 2 (http://www.neurovr2.org)--that improves the possibility for the therapist to enhance the patient's feeling of familiarity and intimacy with the virtual scene, by using external sounds, photos or videos. More, when running a simulation, the system offers a set of standard features that contribute to increase the realism of the simulated scene. These include collision detection to control movements in the environment, realistic walk-style motion, advanced lighting techniques for enhanced image quality, and streaming of video textures using alpha channel for transparency.
