Abstract

A portable electronic apparatus and an interactive human face login method are disclosed. The portable electronic apparatus comprises a face database, a user interface, an image capturing device, and a recognition circuit. The face database stores a plurality of facial expression feature information. The user interface randomly generates a plurality of facial expression indications used for guiding a user to sequentially show a plurality of facial expressions. The image capturing device captures the facial expressions to output a plurality of facial expression images. The recognition circuit receives a login request and determines whether the facial expressions are consistent with the facial expression indications according to the facial expression feature information and the facial expression images. The login request is allowed if the facial expressions are consistent with the facial expression indications.
