Instantaneous walking speed estimation for daily life activity monitoring based on wrist acceleration

摘要: Walking is the main activity of daily life, and there a great interest to characterize this by instantaneous walking speed travelled distance per day. An ideal way monitor using accelerometer on wrist like watch. However, for estimating speed, accelerations cannot simply be integrated because sensor drift arm movement artifact. Moreover, counting total number steps multiplying it subject dependent coefficient not practical as requires specific calibration does provide an estimate speed. In study we train linear regression model obtain free based wrist.
