    • Designing an e-Health Program for Lifestyle Changes in Diabetes Care A Qualitative Pre-Study in Norway 

      Rishaug, Tina; Henriksen, André; Aas, Anne-Marie; Hartvigsen, Gunnar; Birkeland, Kåre Inge; Årsand, Eirik (Chapter; Bokkapittel, 2022-08-22)
      Type 2 diabetes mellitus (T2D) and prediabetes prevalence rates are high. Consequences are serious, but current treatment is often not efficient for achieving remission. Remission may be achieved through lifestyle intervention. Frequent follow-up is necessary, and health care personnel (HCP) lack resources, time, and often adequate knowledge. Self-management of T2D can benefit from better use of ...

      <i>Background</i>: Sickle cell disease (SCD) is a hematological genetic disease affecting over 25 million people worldwide. The main clinical manifestations of SCD, hemolytic anemia and vaso-occlusion, lead to chronic pain and organ damages. With recent advances in childhood care, high-income countries have seen SCD drift from a disease of early childhood mortality to a neglected chronic disease of ...
    • Health research requires efficient platforms for data collection from personal devices 

      Johannessen, Erlend; Henriksen, André; Årsand, Eirik; Horsch, Alexander; Johansson, Jonas; Hartvigsen, Gunnar (Journal article; Tidsskriftartikkel; Peer reviewed, 2023)
      Data from consumer-based devices for collecting personal health-related data could be useful in diagnostics and treatment. This requires a flexible and scalable software and system architecture to handle the data. This study examines the existing mSpider platform, addresses shortcomings in security and development, and suggests a full risk analysis, a more loosely coupled component- based system for ...
    • Kontekstsensitiv tilpasning av interaksjonsmodi mot mobile terminaler 

      Henriksen, André (Master thesis; Mastergradsoppgave, 2003-12-15)
      Denne oppgaven ser på mulighetene for å bruke kontekstinformasjon for å kunne tilpasse interaksjonsmodi mot mobile terminaler, spesielt mobiltelefoner. Hensikten er å illustrere hvordan brukere av et transportselskap automatisk kan motta beskjeder om forsinkelser på bussavganger han/hun er interessert i, samt andre beskjeder fra transportselskapet. Brukere skal altså slippe å kjenne til vanlige ...
