Sammanfattning
This master’s thesis covers the development of an application for patients and healthcare
providers training to alleviate Osteoarthritis symptoms. The method used in
this application to judge if the training is performed in a safe and correct manner is
by using angles. These angles are measured using the smartphone accelerometers,
magnetometer and gyroscope. These signals are used to provide direct feedback to
the user, using Euler angles and a complementary filter.
The results indicate that the smartphone application can measure the angles of
interest with good precision. There is still need for further development due to the
problems of gimbal locking using Euler angles. Conclusions from the work is that
there is great potential using the application both from a patient perspective and
as a long term method for healthcare providers to follow up without physical visits.
