  1. 11. Understanding virtual speakers

    Författare :Jens Nirme; The Educational Technology Group; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Verbal Comprehension; Multimodality; Audiovisual integration; Gesture; Educational Technology;

    Sammanfattning : This thesis addresses how verbal comprehension is affected by seeing the speaker and in particular when the speaker is an animated virtual speaker. Two people visually co-present – one talking and the other listening, trying to comprehend what is said – is a central and critical scenario whether one is interested in human cognition, communication or learning.

  3. 12. Getting physical : tangibles in a distributed virtual environment

    Författare :Mattias Bergström; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design; Funktionella produkter; Functional Product Development;

    Sammanfattning : The design of products is an increasingly complex task, where companies do not have and do not want the in-house competence to manage the development of entire products. Consequently, companies outsource parts of product development projects to other companies or join in partnerships. LÄS MER

  4. 13. Virtual Reality Technology for Factory Layout Planning

    Författare :Liang Gong; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; 3D Laser Scanning; Factory Layout Planning; Virtual Reality; Virtual Factory Modelling;

    Sammanfattning : Factory layout planning (FLP) has been a long-standing area that largely influences the overall productivity of the manufacturing practice.
