  1. 6. Reconsidering the avatar : From user mirror to interaction locus

    Författare :Kai-Mikael Jää-Aro; Yngve Sundblad; Wolfgang Prinz; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; virtual environments; computer-supported collaborative work; user representation; human-computer interaction;

    Sammanfattning : This thesis is concerned with shared virtual environmentsfor collaborative work. An important aspect of shared virtualenvironments is the avatar, the representation of the user inthe virtual world. LÄS MER

  3. 7. Enabling boundary-crossing collaboration for innovation : issues for collaborative working environments

    Författare :Marita Holst; Luleå tekniska universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Informatik; Informatics;

    Sammanfattning : In this thesis, boundary-crossing collaborative knowledge work aiming for innovation and use of ICT is in focus. The starting point for the research was the proposition that we still have much to learn about boundary- crossing collaboration for innovation and the use of ICT before we can design enabling and supporting ICT and collaborative working environments.

  4. 8. The Influence of Modality Combinations on Communication in Collaborative Virtual Environments

    Författare :Jonas Moll; Eva-Lotta Sallnäs-Pysander; Kerstin Severinson Eklundh; Stephen Brewster; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Haptics; Audio; Multimodality; Collaboration; Communication;

    Sammanfattning : Although many studies have been performed on collaboration in multimodal interfaces not many of these have looked specifically on how the supported modalities influence the task solving strategies chosen and the communication between users solving a joint task in collaborative virtual environments. Therefore, the thesis studies performed aimed at shedding light on these aspects of multimodality. LÄS MER

  5. 9. Design and Evaluation of 3D Multimodal Virtual Environments for Visually Impaired People

    Författare :Ying Ying Huang; Yngve Sundblad; Eva-Lotta Sallnäs; Charlotte Magnusson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Multimodal interaction; 3D worlds; Haptics; Audio; Visually impaired users; Collaboration; Navigation; Computer science; Datavetenskap;

    Sammanfattning : Spatial information presented visually is not easily accessible to visually impairedusers. Current technologies, such as screen readers, cannot intuitively conveyspatial layout or structure. This lack of overview is an obstacle for a visuallyimpaired user, both when using the computer individually and when collaboratingwith other users. LÄS MER

  7. 10. Computing at the speed of paper : ubiquitous computing environments for healthcare professionals

    Författare :Magnus Bång; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap;

    Sammanfattning : Despite the introduction of computers in most work environments, the anticipated paperless workplace has not yet emerged. Research has documented that material objects are essential in the organization of thought and that they support everyday collaborative processes performed by staff members. LÄS MER
