    Sammanfattning : In recent years mobile phones and the internet have played an increasingly significant role, assisting in the organization of dissent worldwide. Only a few studies have dealt with the interplay between social movements and these digital media in Latin America so far. LÄS MER

  4. 23. Designing guidance along audio-haptically augmented paths in a city environment

    Författare :Delphine Szymczak; Certec - Rehabiliteringsteknik och Design; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Activity theory; Cultural historical; design; evaluation; iterative design; user-centered design; audio-tactile; multimodal; mobile; pedestrian navigation; scanning; tourist guide; vibration; in-use; focus; environment;

    Sammanfattning : The main purpose of this thesis is to show in a case study how it is possible to inform, with Activity Theory, the design and evaluation of a pedestrian navigation system that uses audio-tactile feedback. The case study consists of an iterative design process that results in a tourist guide application used in a mobile phone. LÄS MER

  5. 24. Wrist and thumb joint postures and motions: Measurements using electrogoniometry and EMG

    Författare :Per Jonsson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Wrist joint; Finger joint; Electromyography; Accuracy; Electrogoniometry; Input device; Information and communication technology; Mobile phone; Muscle activity; Posture; Thumb; Wrist;

    Sammanfattning : Correct measurements of the joints’ extreme postures, velocity and repetitiveness are important for studies of the origin of musculoskeletal disorders. Posture measurements of wrist and thumb joints may also provide insights into input device designs that may reduce effort and/or facilitate productivity. LÄS MER

  7. 25. Physical exposure, musculoskeletal symptoms and attitudes related to ICT use

    Författare :Ewa Gustafsson; Göteborgs universitet; []
    Nyckelord :Input device; Wrist movements; Electrogoniometry; EMG; Muscle activity; Thumb movements; Working technique; Information and communication technology; Computer mouse; Mobile phone;

    Sammanfattning : High prevalence of musculoskeletal symptoms/disorders in neck and upper extremities are reported among computer users. Considering the widespread use of information and communication technology (ICT) and mobile phones becoming more and more like computers with small keyboards it is of importance to identify the factors and conditions related to this use, that influence our health.
