Abstract: Proposed are an apparatus and a method for supporting language learning, which can classify voices of a language learning video for each character, convert the voices for each character into texts, and provide utterance levels of characters. The proposed apparatus for supporting language learning generates voices for each person classified for each character through collection of voices in a language learning video, which are uttered on the language learning video being viewed by a learner, configures utterance levels (i.e., person levels) of the characters through conversion of the voices for each person into texts for each person, and displays a learning support screen including the texts for each person and the utterance levels.

Abstract: This disclosure presents a system and a method for supporting study based on personality type which set a personality type of a learner and provide a different type of wrong answer note according to the personality type to strengthen the learner's self-directedness and satisfy the learner's own personalization bodily sensation rate. The learning support server of the presented system for supporting study based on personality type detects the learner's personality type, sets the learner's personality type when the detected learner's personality type is ‘Null’, transmits learning information to a learning terminal when the personality type is set, and provides a wrong answer note generated in a form corresponding to the learner's personality type in response to a wrong answer note provision request of the learning terminal.

Abstract: There are provided a learning recommendation apparatus and method for detecting a problem from an image through character recognition and providing at least one sub-topic learning among a plurality of sub-topic learnings related to the detected problem. The provided learning recommendation apparatus recommends, as a recommendation target, a plurality of learning topics including the concept of a formula which has been read through the character recognition for an image, wherein a priority order is set to the plurality of learning topics based on the concept distance between the learning topic and the learning history, and the learning topics are recommended so that the learning topic having a higher priority order is located at a higher position.

Abstract: Disclosed are a reading support apparatus which can detect a user input (touch and/or drag) conducted on a real book by using one camera, and a user input detection method using the same. The reading support apparatus sets a finger and/or nail on a target surface image captured through one camera to touch recognition reference, detects, as a user input, a user's touch or drag conducted on the surface of the real book by comparing the finger and/or nail included in the target surface image to the touch recognition reference, and provides an action corresponding to the user input.
