    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.

  3. 2. Extending a networked robot system to include humans, tiny devices, and everyday objects

    Författare :Md. Jayedur Rashid; Mathias Broxvall; Alessandro Saffiotti; Thomas Pederson; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Networked Robot System NRS ; Ecology of Physically Embedded Intellignet Systems; Middleware; Tiny Embedded devices; Network of distributed ubiquitous sensors and actuators; Object proxies; human proxie; TECHNOLOGY; TEKNIKVETENSKAP; Computer science; Datavetenskap; Computer and Systems Science; Data- och systemvetenskap;

    Sammanfattning : In networked robot systems (NRS), robots and robotic devices are distributed in the environment; typically tasks are performed by cooperation and coordination of such multiple networked components. NRS offer advantages over monolithic systems in terms of modularity, flexibility and cost effectiveness, and they are thus becoming a mainstream approach to the inclusion of robotic solutions in everyday environments.

  4. 3. Egocentric interaction for ambient intelligence

    Författare :Dipak Surie; Lars-Erik Janlert; Thomas Pederson; Hans Gellersen; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ambient Intelligence; Human-Computer Interaction; Context-Aware computing; Ubiquitous Computing; Mixed-Reality; Smart Environments; Activity-Based Computing; Ambient Ecology; business data processing; administrativ databehandling;

    Sammanfattning : Ambient intelligence refers to the vision of computationally augmented everyday environments that are sensitive, adaptive and responsive to humans and intelligently support their daily lives. Ambient ecologies are the infrastructures of ambient intelligence. LÄS MER

    Sammanfattning : Ti-6Al-4V manufactured by electron beam melting Keywords: Additive manufacturing, high-temperature tensile properties, low cycle fatigue, neutron diffraction, fatigue crack growth ISBN: 978-91-89325-27-2 (Printed) 978-91-89325-26-5 (Electronic) Ti-6Al-4V is the most widely used α+β titanium alloy in aerospace engine applications due to its high specific strength. Typically, the alloy is manufactured as castings or forgings and then machined to final geometry. LÄS MER
