Collecting health-related research data using consumer-based wireless smart scales
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-03-14)Background: Serious public-health concerns such as overweight and obesity are in many cases caused by excess intake of food combined with decreases in physical activity. Smart scales with wireless data transfer can, together with smart watches and trackers, observe changes in the population’s health. They can present us with a picture of our metabolism, body health, and disease risks. Combining ... -
Consumer-Based Activity Trackers as a Tool for Physical Activity Monitoring in Epidemiological Studies During the COVID-19 Pandemic: Development and Usability Study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-04-23)Background: Consumer-based physical activity trackers have increased in popularity. The widespread use of these devices and the long-term nature of the recorded data provides a valuable source of physical activity data for epidemiological research. The challenges include the large heterogeneity between activity tracker models in terms of available data types, the accuracy of recorded data, and how ... -
Dataset of Consumer-Based Activity Trackers as a Tool for Physical Activity Monitoring in Epidemiological Studies During the COVID-19 Pandemic
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-03-01)Physical activity (PA) data were downloaded from 113 participants who owned a Garmin or Fitbit activity tracker in 2019 and 2020. Upon participant authorization, data were automatically downloaded from the Garmin and Fitbit cloud storages. The mSpider tool, a solution for automatic and continuous data extraction from activity tracker providers, were used to download participant data. Available ... -
Health research requires efficient platforms for data collection from personal devices
(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 ... -
Incremental Information Retrieval. Finding new information by registering and ignoring already seen search results
(Master thesis; Mastergradsoppgave, 2017-05-15)When searching the internet today we want immediate answers. We often search for a person, or a solution to a problem, or some topic we are interested in. The result quality of this kind of search is pretty good, most of the time we get the answers we need. The results, though, seems to be minor variations on the same results. But what if the search for information is of a different nature, more ... -
Sorterius - An augmented reality app for encouraging outdoor physical activity for people with intellectual disabilities
(Chapter; Bokkapittel, 2022-08-22)Many with intellectual disabilities (ID) have difficulties adhering to current physical activity guidelines. The goal of this study was to develop a mobile app for assisting people with ID to be more physically active. We implemented a solution that combines the digital and real world using augmented reality (AR). Eight people working with people with ID (special education teachers, social workers, ... -
Ubiquitous digital health-related data: clarification of concepts
(Chapter; Bokkapittel, 2022-08-22)The increased development and use of ubiquitous digital services reinforce the trend where health-related data is generated everywhere. Data usage in different areas introduces different terms for the same or similar concepts. This adds to the confusion of what these terms represent. We aim to provide an overview of concepts and terms used in connection with digital twins and in a healthcare context.
