  1. 11. Adding usability : Methods for modelling, user interface design and evaluation

    Författare :Magnus Lif; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Modelling; analysis; design; evaluation; user interface; human computer interaction; system development; usability; utility; methods; workspace; iterative; designer; Materialvetenskap; Materials science; Teknisk materialvetenskap; datavetenskap med inriktning människa-datorinteraktion; Computer Science; human-computer interaction;

    Sammanfattning : Many system development projects fail to provide information systems with high usability. This thesis focuses on how to solve this problem by introducing methods for modelling, user interface design and evaluation. These methods are primarily designed to serve as complements to existing methods for systems development. LÄS MER

  3. 12. Computational Solid Wave Propagation Numerical Techniques and Industrial Applications
