The emotion analysis method includes: obtaining a heart rate signal of the examinee; defining a plurality of candidate emotions from the database; analyzing the heart rate signal to obtain a plurality of target emotion parameters; and analyzing the target emotion parameters to determine one of the candidate emotions corresponding to the heart rate signal by applying an emotion analysis model.

Abstract: A gait evaluation method using a sensor worn by the user for evaluating the gait of the user includes the following steps. A plurality of first acceleration values, a plurality of second acceleration values and a plurality of third acceleration values on a first direction, a second direction and a third direction corresponding to the user within a walking period of the user are obtained from the sensor worn by the user. Based on the first acceleration values, the second acceleration values, the third acceleration values and a wearing position of the sensor on the user, a sway index, a step index and a slouch index related to the user are calculated. A gait evaluation is generated according to the sway index, the step index and the slouch index. An electronic device suitable for applying the gait evaluation method is also provided in the present application.
