Abstract: An aided translation method and a device thereof, belonging to the field of Human-Computer Interaction. The method comprises the steps of: obtaining a destination from the itinerary information of a user; translating the pre-stored personal form-filling information of the user from a source language to a target language when the language of the destination is different from that of the user's usual place of residence, wherein, the target language is the language of the destination; and displaying the personal form-filling information in the target language. The method and a device solve the problem of users in filling in the arrival/departure card caused by unfamiliarity with foreign languages and the form-filling formats, and achieve an effect that users can fill in the arrival/departure card easily by reference to the personal form-filling information displayed in the target language.
