Abstract
A gait pathology detection and monitoring system, and method using rotation, scale, and offset invariant dynamic time warping (RSOI-DTW).
Claims13
A gait pathology detection and monitoring method, comprising:
- securing a personal activity tracking electronic device having an accelerometer sensor onto a leg of a user;
- detecting gait movement of the user during walking using the personal activity tracking electronic device;
- generating gait data of the user from the detected gait movement of the user during the walking;
- demonstrating at least one style of gait of the user when generating the gait data;
- processing the generated gait data using each of dynamic time warping (DTW) and rotation, scale, and offset (RSO) invariant dynamic time warping (RSOI-DTW), even when rotation of the accelerometer sensor is present during the detecting of the gait movement of the user during walking using the personal activity tracking device;
- and
- comparing results of the processing of the generated gait data using DTW and RSOI-DTW, respectively, to determine any gait recognition problem.
4 more elements
A gait pathology detection and monitoring system, comprising:
- a personal activity tracking electronic device having an accelerometer sensor, the personal activity tracking electronic device being configured to fit onto a leg of a user, detect gait movement of the user when walking, and generate, from the detected gait movement of the user, gait data of the user demonstrating at least one style of gait of the user;
- and
- an electronic apparatus configured to (a) receive the generated gait data of the user, (b) process the generated gait data using each of dynamic time warping (DTW) and rotation, scale, and offset (RSO) invariant dynamic time warping (RSOI-DTW), even when rotation of the accelerometer sensor is present during the detecting of the gait movement of the user when walking, and (c) compare results of the processing of the generated gait data using DTW and RSOI-DTW, respectively, to determine any gait recognition problem.
