1. 1. Model-based Methods in Motion Capture

   Författare :Kjartan Halvorsen; Antonie J. van den Bogert; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Systems engineering; Systemteknik; Systemanalys; Systems Analysis;

   Sammanfattning : This thesis concerns the use of kinematic models and shape models to solve the problem of estimating the motion of articulated objects from image data. The data considered in the first part of the thesis are trajectories of 3D feature points (markers). In the second part, image sequences are considered. LÄS MER

3. 2. Simulations of human movements through temporal discretization and optimization

   Författare :Manindra Kaphle; Anders Eriksson; Kjartan Halvorsen; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Forward dynamics; Biomechanics; Temporal discretization; Optimization; Engineering mechanics; Teknisk mekanik;

   Sammanfattning : Study of physical phenomena by means of mathematical models is common in various branches of engineering and science. In biomechanics, modelling often involves studying human motion by treating the body as a mechanical system made of interconnected rigid links. LÄS MER

4. 3. Inertial motion capture for ambulatory analysis of human movement and balance

   Författare :Fredrik Olsson; Kjartan Halvorsen; Peter H. Veltink; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Inertial sensors; Human motion capture; Calibration; Neuromuscular control; Human balance; Tremor quantification;

   Sammanfattning : Inertial sensors (accelerometers and gyroscopes) are ubiquitous in today’s society, where they can be found in many of our everyday mobile devices. These sensors are capable of recording the movement of the device, and by extension, the movement of humans carrying or interacting with the device. LÄS MER

5. 4. Modeling and assessment of human balance and movement disorders using inertial sensors

   Författare :Fredrik Olsson; Kjartan Halvorsen; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

   Sammanfattning : Inertial sensors and magnetometers are abundant in today's society, where they can be found in many of our everyday electronic devices, such as smart phones or smart watches. Their primary function is to measure the movement and orientation of the device and provide this information for the apps that request it. LÄS MER
