Sharing Human-Generated Observations by Integrating HMI and the Semantic Sensor Web
Current âInternet of Thingsâ concepts point to a future where connected objects gather meaningful information about their environment and share it with other objects and people. In particular, objects embedding Human Machine Interaction (HMI), such as mobile devices and, increasingly, connected vehicles, home appliances, urban interactive infrastructures, etc., may not only be conceived as sources of sensor information, but, through interaction with their users, they can also produce highly valuable context-aware human-generated observations. We believe that the great promise offered by combining and sharing all of the different sources of information available can be realized through the integration of HMI and Semantic Sensor Web technologies. This paper presents a technological framework that harmonizes two of the most influential HMI and Sensor Web initiatives: the W3Câs Multimodal Architecture and Interfaces (MMI) and the Open Geospatial Consortium (OGC) Sensor Web Enablement (SWE) with its semantic extension, respectively. Although the proposed framework is general enough to be applied in a variety of connected objects integrating HMI, a particular development is presented for a connected car scenario where driversâ observations about the traffic or their environment are shared across the Semantic Sensor Web. For implementation and evaluation purposes an on-board OSGi (Open Services Gateway Initiative) architecture was built, integrating several available HMI, Sensor Web and Semantic Web technologies. A technical performance test and a conceptual validation of the scenario with potential users are reported, with results suggesting the approach is soun
Multimodal person recognition for human-vehicle interaction
Next-generation vehicles will undoubtedly feature biometric person recognition as part of an effort to improve the driving experience. Today's technology prevents such systems from operating satisfactorily under adverse conditions. A proposed framework for achieving person recognition successfully combines different biometric modalities, borne out in two case studies
Usable Interface Design for Everyone
En el diseño de "interfaces para todo el mundo" para los sistemas interactivos, es importante tener en cuenta factores como el costo, el mercado de destino, el estado del medio ambiente,etc. Los interfaces de usuario son fundamentales para el proceso de desarrollo de cualquier aplicaciĂłn, y su diseño debe estar contemplado desde el principio. De las distintas partes de un sistema (hardware y software), es la interfaz el sistema que permite al usuario el acceso a los recursos informĂĄticos. Los siete principios del "Diseño Universal" o "Diseño para Todos" se centran en un diseño utilizable universal, pero al mismo tiempo reconocer la influencia de factores internos y externos. Los cambios estructurales en los servicios sociales y de salud podrĂan proporcionar un aumento en el bienestar de los ciudadanos de un paĂs a travĂ©s del uso de la programaciĂłn de auto-cuidado y la gestiĂłn proactiva / prevenciĂłn de la enfermedad. Plataformas automatizadas en el hogar pueden actuar como un instrumento que permitan a los usuarios evitar, compensar, mitigar o neutralizar las deficiencias y las dependencias causada por el envejecimiento.When designing âinterfaces for everyoneâ for interactive systems, it
is important to consider factors such as cost, the intended market, the state of
the environment, etc. User interfaces are fundamental for the developmental
process in any application, and its design must be contemplated from the start.
Of the distinct parts of a system (hardware and software), it is the interface that
permits the user access to computer resources. The seven principles of
âUniversal Designâ or âDesign for Everyoneâ focus on a universal usable
design, but at the same time acknowledge the influences of internal and external
factors. Structural changes in social and health services could provide an
increase in the well-being of a countryâs citizens through the use of self-care
programming and proactive management/prevention of disease. Automated
home platforms can act as an accessibility instrument which permits users to
avoid, compensate, mitigate, or neutralize the deficiencies and dependencies
caused by living alon
Multi-Moji: Combining Thermal, Vibrotactile and Visual Stimuli to Expand the Affective Range of Feedback
This paper explores the combination of multiple concurrent
modalities for conveying emotional information in HCI:
temperature, vibration and abstract visual displays. Each modality
has been studied individually, but can only convey a
limited range of emotions within two-dimensional valencearousal
space. This paper is the first to systematically combine
multiple modalities to expand the available affective
range. Three studies were conducted: Study 1 measured the
emotionality of vibrotactile feedback by itself; Study 2 measured
the perceived emotional content of three bimodal combinations:
vibrotactile + thermal, vibrotactile + visual and
visual + thermal. Study 3 then combined all three modalities.
Results show that combining modalities increases the available
range of emotional states, particularly in the problematic
top-right and bottom-left quadrants of the dimensional
model. We also provide a novel lookup resource for designers
to identify stimuli to convey a range of emotions
