- Abstract:
- The importance of research on new technologies that could be employed in care services for elderly and disabled persons is highlighted. Advantages of radar sensors, when applied for noninvasive monitoring of such persons in their home environment, are indicated. Methods for estimation of the instantaneous velocity and the mean walking velocity (including automatic detection of time intervals when the person is in motion), on the basis of the measurement data from radar sensors and accelerometers, are described. A novel methodology for evaluation of the estimation uncertainty of the person’s average walking velocity, in an impulseradar-based system for monitoring of movements, is presented. The results of a series of real-world experiments, with a person moving at different predefined velocities, are shown. They are indicating that the accuracy of radar-data-based detection of the person’s motion and estimation of person’s walking velocity may be sufficient for some healthcare applications.
