This paper explores a novel concept called Mobile Electronic Memo whose purpose is to overcome the limitations in terms of interoperability and accessibility imposed by the current technology. To achieve this goal, Mobile Electronic Memos decouple the semantics of the information from the physical and pragmatic constraints of the medium that transports it. We examine related works and standards that could be good candidates for implementing MEMs and describe a prototype implementation that has been realized as a proof of concept.

This paper, which targets a wide audience, focuses on the design of a mobile application that aims to integrate the crowdsourcing paradigm in current Disaster Risk Reduction processes. The design process is integrated in the User Centred Approach, which we apply through a co-design methodology involving end-users, iterative prototyping and development phases, and five in-field evaluations of the implemented solution. We describe both the design activities and the results obtained from end-users’ feedbacks focusing on the perspective of first responders.

The authors present a new artificial cognitive tool integrating sensing and decision making for care purposes. Authors showcase how a combination of virtual sensorial components acquiring daily the concentration of very fine Particulate Matter, one data analysis component triggering long lasting polluted periods cooperates with one humanoid robot actuating information delivery about the harmful conditions and risks of disease exacerbation. The use of humanoid robotic interfaces offers better persuasive capabilities and compliancy of care.

In this context, Information and Communication Technology (ICT) can act as proactive input devices providing multimodal interface components for facilitating long-term user interaction. The present paper reports the first results of the EU-H2020 project "my-AHA", for defining the best combination of voice commands, non-verbal behaviors and gestures. Eight elderly people tested the specific features of different devices (TV, Microsoft Kinect™ v2, smartphone) in two real life scenarios. Results show how natural interaction, such as voice and gestures (gathered by Microsoft Kinect™ v2) are more appreciated than the remote control based on smartphone.

During emergency situations different forms of cooperation take place, including the crowdsourcing, which is envisioned by many Disaster Risk Management approaches to enable citizens to support the emergency management process. However, crowdsourcing is a challenging paradigm as it requires a sustained engagement in order to be effective. In this paper we propose a gamification strategy for crowdsourced Disaster Risk Management services aimed to increase awareness, engagement, and change people behaviors.

In our research we adopted the Human Centered Approach to design a cognitive rehabilitation platform that is able to provide tools and features tailored to the professional needs and strategies and also able to engage patients in their treatment process. In order to explore the clinicians' point of view on the neuropsychological intervention strategies, we applied two different techniques often used in human factors research: the Critical Decision Method to study professionals' strategies with a descriptive perspective, and the Hierarchical Task Analysis to analyze the processes with a normative view. The results of our research showed that the hybrid approach adopted allowed us to have a better focus on the cognitive rehabilitation process and on the professionals' decision making mechanism. This led to a better understanding of functional requirements for supporting clinician's strategic decision making, in terms of personalization of treatments, cognitive exercises settings and feedback customization. In conclusion, our research highlights the value of the CDM to focus deeply on which functionalities professionals require from a cognitive telerehabilitation system and allowed us to design more precisely clinician-patients interactions inside the system compared to prescriptive methods currently used. Our study offers contribution to the comprehension of the rehabilitation processes, suggesting the positive impacts of an "extended" clinic treatment by adopting a flexible and adaptable tool.

This evolution influences user experiences and creates new paradigms for interaction, leading to an increased importance of user evaluation and assessment on new systems interfaces and usability, to validate platform design and development from the users' point of view. The REVERIE research project aims to develop a virtual environment service for realistic inter-personal interaction. This paper describes the design challenges faced during the development process of user interfaces and the adopted methodological approach to user evaluation and assessment.

This paper presents the design, implementation and evaluation of a network solution for multi-party real-time communication of these types of content. This prototype includes a UDP/TCP multi-streaming kernel that includes media synchronization support, packet scheduling, loss resilient real-time transmission and an easy to use blocking and non-blocking API. To compress the live reconstructed 3D data streams that represent the natural user, two categories of 3D mesh codecs were integrated: a highly adaptive real-time geometry driven mesh codec and a fast single rate codec that provides better performance at high resolutions. Subjective tests with 16 subjects indicate that only modest perceptual degradation of the highly realistic 3D natural user is introduced, especially when the users in the virtual world are at a distance. We developed a session management protocol for setting up streams based on the specific 3DTI capabilities allowing device scalability from light (render only) to heavy clients (rendering and 3D Capturing). Additionally, a distributed messaging system via web-sockets and cloud infrastructures based on publish and subscribe was integrated for real-time delivery of avatar and other AI data.

The aim was to perform literature studies in order to find suitable objective and subjective quality evaluation methods, and to design and implement these into a video quality analysis tool with an intuitive user interface. The focus was on MPEG-4 encoded sequences with bit rates ranging from 64 through 384 kbps. The implemented objective methods are based on temporal and spatial derivatives. This approach was found in an ANSI recommendation. Some rather extensively modified versions of the parameters found in this recommendation were also implemented. They were named Diff_SI and Diff_TI. The modified parameters are based on differences between images instead of differences between scalar quantities, derived from the images, as in the in the ANSI recommendation. By using this approach, the information about where in the images the errors occur is included, and not just the magnitude. The peak signal to noise ratio (PSNR) parameter was also implemented. The quality parameters were evaluated using MPEG-4 sequences with different bit rates and different levels of distortion as input data. In order to obtain figures of the subjectively experienced quality, MOS tests were performed. Among the investigated objective parameters the modified ones, DIff_TI and DIff_SI, were found to have the highest correlation with subjectively experienced quality. Although often described as unreliable in other reports, the PSNR parameter was also found to agree well with the results from the MOS tests. The parameters implemented as suggested in the ANSI report were in some cases found to totally disagree with the results from the MOS tests and must therefor be considered less reliable. Most effort has been made in developing the software. The application is designed to run under a UNIX operating system. The programming language used is c with small contributions of C++. For the graphical user interface the Motif class library has been used. The application can display ordinary YUV-files and MPEG-4 encoded files and is designed so that it is easy to add subjective and objective test methods. Further work should be concentrated on adding such methods. Other improvements could be to improve the algorithms used for the extraction of spatial-and temporal information.

This work focuses on the definition of a co-design methodology to integrate a crowdsourcing solution in the DRR processes. We define the proposed methodology, and implement it involving operators and experts in the DRR domain (crisis managers, technical services, first responders). We show how a participatory design approach helps in the design of a crowdsourcing solution that experts are willing to integrate into their DRR procedures.

In a mixed methods approach, data was initially obtained from an online questionnaire completed by older health technology users and used in a regression analysis, where factors from the Technology Acceptance Model (TAM) and the Social Cognitive Theory (SCT) served as predictors for health technology use (HTU). Further, in-depth interviews were conducted with older adults to gain insights into technology use and physical activity behaviour of older adults. The regression analysis showed that the TAM and SCT factors accounted for a significant proportion of variance (39.5%) in HTU. Significant predictors of HTU were physical activity (.399**), social support (.287*), and expectations regarding individual health (.440*) and physical appearance (−.470**), indicating physical activity as mediator for HTU. The qualitative analysis indicated the conflation of technology support with social environments as key for physical activity behaviour in older adults. The findings indicate physical activity as a mediator in HTU by older adults and suggest that the consideration of social factors in health technology design may facilitate the uptake of AHA technologies.

The concept has been designed and prototyped to study a situated interaction modality, bridging digital information and the surrounding physical world, by means of familiar objects (a poster, a smartphone and/or a TV screen). Two different usage scenarios have driven the design and the implementation of one prototype born to enable offline mediated interactions among public administrations and citizens.
