abstract="The authors wish to add one reference [1] to this paper [2].   On page 1, the original sentences are as follows: Progress toward new methods without cameras has been made through the use of accelerometer sensors mounted on the structure to capture floor vibration for human activities detection [13-15].  Correction to be: Progress toward new methods without cameras has been made through the use of accelerometer sensors mounted on the structure to capture floor vibration for human activities detection [13-16].  The sequential references originally in the paper (i.e., [16-47]) will shift by one (i.e., [17-48]).  The authors apologize for any inconvenience caused and state that the scientific conclusions are unaffected. The original article has been updated.<p /> <p>Language: en</p>",
