Dashboard
We are currently in the process of developing an interactive dashboard that includes all 967 validation studies. As a first step, we enter all relevant information from the studies into a database. Thereafter, we are planning to set up an interactive dashboard with various functions such as filtering by specific wearables, wearing positions, or other information. In the future, researchers should be able to regularly add recent validation studies independently.
In the following we will list our steps and the progress we are making.
Identify and Extract Interesting Information
First, we need to collect all the studies we have identified in the reviews and extract the relevant information from each study.
Cleaning up Study Entries
In the next step, the extracted data must be cleaned and prepared for insertion into a database.
Building the Database
Once the data has been cleaned and prepared for insertion into a database, the database is created. At the same time, a repository is created in which all data is available openly and unprocessed, enabling new data records to be entered, existing data records to be corrected and obsolete data records to be deleted, for example.
