Abstract
A method for detecting fatigue is provided herein. The present invention includes the following steps: measuring a plurality of physiological feature data from a user in continuous time to generate a feature sequence; computing the rate of drop and/or calculating the difference of the rate of drop based on the feature sequence; and determining the fatigue level of the user by analyzing the rate of drop and the difference of the rate of drop. A fatigue detecting device is also disclosed here. The present invention can be utilized to effectively monitor the fatigue level of the user.
