  1. 36. Top-Down Designers vs Bottom-Up Users : limitations of Heuristic Evaluations on Games

    Författare :Björn Strååt; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Design; Heuristic evaluation; video games; expert analysis; user comments; Computer and Systems Sciences; data- och systemvetenskap;

    Sammanfattning : Heuristic evaluations are a common way to measure software usability, both during development and to assess existing systems. Generic heuristic tools are aimed at productivity software, but many software domains require domain-specific heuristics. LÄS MER

  3. 37. Towards markerless analysis of human motion

    Författare :Björn Holmberg; Håkan Lanshammar; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering with specialization in Systems Analysis; Elektroteknik med inriktning mot systemanalys;

    Sammanfattning : The topic for this thesis is the analysis of human movement, or more specifically, markerless analysis of human movement from video material. By markerless analysis is meant that the full image material is used as input in contrast with traditional marker systems that only use the positions of marker centers. LÄS MER

  4. 38. Social Order of the Co-Located Mobile Phone : Practices of collaborative mobile phone use

    Författare :Moira McGregor; Barry Brown; Christian Licoppe; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Human-computer interaction; Mobile phones; Ethnography; Video analysis; Collaborative interaction; Field studies; Computer and Systems Sciences; data- och systemvetenskap;

    Sammanfattning : This thesis examines mundane practices of everyday phone use to make conceptual, empirical and methodological contributions to ongoing research on mobile technology. It argues that we do not yet have a clear understanding of how the mobile phone is used–who does what, when and why. LÄS MER

  5. 39. Större våld än nöden kräver? : Medievåldsdebatten i Sverige 1980-1995

    Författare :Ulf Dalquist; Sociologi; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TV; video; social problems; media effects; media effects research; social constructivism; moral panic; claims-making; censorship; Press and communication sciences; rhetorics; Media violence; film; Journalistik; media; kommunikation;

    Sammanfattning : This study is an attempt to analyze the social construction of media violence in the Swedish press debate 1980-1995. Altogether, 1029 articles from seven of Sweden's biggest daily and evening papers were qualitatively analyzed. Numerous claims refer to scientific 'proof' that media violence breeds personal aggression. LÄS MER

  7. 40. Robust Real-Time Estimation of Region Displacements in Video Sequences

    Författare :Johan Skoglund; Michael Felsberg; Hanno Scharr; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; tracking; subpixel; real time; covariance; pose estimation; Image analysis; Bildanalys;

    Sammanfattning : The possibility to use real-time computer vision in video sequences gives many opportunities for a system to interact with the environment. Possible ways for interaction are e.g. augmented reality like in the MATRIS project where the purpose is to add new objects into the video sequence, or surveillance where the purpose is to find abnormal events.
