1. 6. From Signal to Social : Steps Towards Pervasive Social Context

   Författare :Håkan Jonsson; Institutionen för datavetenskap; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; context-awareness; social context; mobile phones;

   Sammanfattning : The widespread adoption of smartphones with advanced sensing, computing and data transfer capabilities has made scientific studies of human social behavior possible at a previously unprecedented scale. It has also allowed context-awareness to become a natural feature in many applications using features such as activity recognition and location information. LÄS MER

3. 7. Quality of experience measurement, prediction and provisioning in heterogeneous access networks

   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Quality of Experience; context awareness; situation awareness; predicion; proactive adaptation; Pervasive Mobile Computing; Distribuerade datorsystem;

   Sammanfattning : In mobile computing systems, users can access network services anywhere and anytime using mobile devices such as tablets and smart phones. Users usually have some expectations about the services provided to them by different service providers, for example, telecommunication operators and network providers. LÄS MER

4. 8. From Conceptual Links to Causal Relations — Physical-Virtual Artefacts in Mixed-Reality Space

   Författare :Thomas Pederson; Lars-Erik Janlert; William Buxton; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Människa-dator-interaktion; Human-Computer Interaction; Mixed Reality; Augmented Reality; Ubiquitous Computing; Pervasive Computing; Graspable User Interfaces; Tangible User Interfaces; Wearable Computing; Context Awareness; User Modelling; Interaction Design; Systems Design; Människa-dator-interaktion; Information technology; Informationsteknologi; business data processing; administrativ databehandling;

   Sammanfattning : This thesis presents a set of concepts and a general design approach for designing Mixed Reality environments based on the idea that the physical (real) world and the virtual (digital) world are equally important and share many properties. Focus is on the design of a technology infrastructure intended to relieve people from some of the extra efforts currently needed when performing activities that make heavy use of both worlds.

5. 9. Cooperative Context-Aware Setup and Performance of Surveillance Missions Using Static and Mobile Wireless Sensor Networks

   Författare :Edison Pignaton de Freitas; Tony Larsson; Carlos Eduardo Pereira; Franz Josef Rammig; Högskolan i Halmstad; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Surveillance systems; Wireless sensor network; Cooperative sensors; Mobile sensors; Biologically-inspired networking; Context awareness;

   Sammanfattning : Surveillance systems are usually employed to monitor wide areas in which their usersaim to detect and/or observe events or phenomena of their interest. The use ofwireless sensor networks in such systems is of particular interest as these networks can provide a relative low cost and robust solution to cover large areas. LÄS MER

7. 10. Complex activity recognition and context validation within social interaction tools

   Författare :Saguna Saguna; Christian Becker; Luleå tekniska universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; context awareness; activity recognition; social networks; situation awareness; HCI; complex activity recognition; sensors; Prototype evaluation; SACAAR; OAT4CDAT; online activity toolkit; context driven activity theory; wearable computing; smart homes; presence; machine learning; Markov chains; Pervasive Mobile Computing; Distribuerade datorsystem;

   Sammanfattning : Human activity recognition using sensing technology is crucial in achieving pervasive and ubiquitous computing paradigms. It can be applied in many domains such as health-care, aged-care, personal-informatics, industry, sports and military. LÄS MER
