Abstract: In a gait evaluation system, qualitative measurement value acquirers acquire at least measurement values of a stride length and a cadence as qualitative parameters indicating a walking form, measured by a measurement device worn by a subject. A qualitative result determination unit determines an evaluation result regarding a walking form using, as a certain evaluation model, an evaluation formula set such that a weight is added at least to the measurement value of the stride length. The measurement value of the stride length is a ratio of an average stride length to the height of the subject measured.

The method includes generating first display data for a display to display user marks at intervals so as to be added one by one as a time elapses from a timing. The intervals each correspond to a user's step length of a user obtained based on measured data on running or walking of the user. The user marks each represent a position where a foot of the user lands by one step. The method further includes generating second display data for the display to display reference marks at intervals so as to be added one by one as the time elapses. The intervals each correspond to a predetermined reference step length. The reference marks each represent a position where a reference foot lands by one step.
