Abstract: A walking analysis method includes measuring impacts due to floor landing occurring during walking; identifying an impact section before floor landing, a free fall section, and an impact peak section by floor landing in an impact graph over time; analyzing at least one impact-related parameter for the impact section before floor landing, the free fall section, and the impact peak section by floor landing; and determining a walking-related accident type according to a result of analyzing the at least one impact-related parameter. Accordingly, by classifying and detecting a variety of accidents that may actually occur, the main walking characteristics that are dangerous in the actual accident can be extracted.
