Abstract: The present invention relates to a braille input and output device which recognizes a normal word transmitted from the outside as braille by a tactile sense of a person and converts a braille input through an input key assembly into a normal word to wirely or wirelessly transmit the normal word. According to the present invention, the braille input through the input key assembly is reversely translated into the normal word or the normal word which is transmitted from a wirelessly connected external apparatus is translated into braille so that information which is input as the braille is translated into the normal word to be transmitted to the external apparatus.

Abstract: Disclosed are an image correction method and apparatus for a visually impaired person, which are capable of dividing, enlarging, and photographing a subject to be photographed, correcting images photographed in a divided state, and providing one image. The image correction method includes: a dividing process of dividing a subject to be photographed into at least two zones; an individual photographing process of, by an image photographing unit, photographing each of the divided zones along an arbitrarily set course; an image correcting process of correcting skewness of an image of each of the photographed zones; and an image synthesizing process of synthesizing the corrected images into one image. Thus, the image is divided, enlarged, and photographed, and the photographed images are generated into one image. Thereby, a high-resolution image is provided along with a high character recognition rate and a still image is provided with a high resolution.

Abstract: Disclosed is a system for providing video for a visually impaired person. The system captures video of a subject to be captured using a video capturing unit, compresses the captured video, and employs wireless data transmission for transmitting the compressed video over a wireless communication network in real time. The system includes a video capturing unit for capturing video of a subject, and a video output unit for controlling the video capturing unit and displaying the video captured by the video capturing unit.

Abstract: Disclosed herein is an image magnifying apparatus which automatically brings a target into focus using a diopter lens depending on whether the target is at a short distance or at a long distance. The orientation of a camera and short- or long-distance focusing of a camera lens can be automatically controlled to provide a clear image to a user, whereby even a user with low vision, a blind user, an aged user, a hand tremor user, etc. can easily use the apparatus. Furthermore, the present invention provides lighting suitable for user environment, thus providing a clear image to the user.

Abstract: Provided is a portable magnifying apparatus that can be easily carried around. More particularly, provided is a portable magnifying apparatus which is conveniently used for users either left-handed or right-handed and has a multi angular positioned handle that can be manipulated without putting strain on the wrist.

Abstract: Disclosed is a portable video magnifying apparatus. The video magnifying apparatus of the present invention comprises a main frame; a short distance image detecting part which is pivotably disposed at the main frame so as to allow proximity photographing with respect to a subject on a right under surface of the short distance image detecting part or therearound; a long distance image detecting part which is provided with a long distance photographing lens for photographing a long distance subject and which is disposed at the main frame; and a display part which outputs one out of the short distance image, the long distance image and an image input through an external portion, which is selected by a user. Therefore, it is possible to help the weak-sighted or aged person.

Abstract: A system and method for interacting with online/offline games using a mobile communication terminal. The system includes a mobile terminal and a mobile game server. The mobile terminal downloads a game executable in an offline mode over a communication channel, plays the downloaded game according to an entry command signal, and transmits update information composed of its own number information assigned for communication and a resultant game score over a wireless channel according to an entry command signal. The mobile game server contains a memory for storing the number information of the mobile terminal and the resultant game score corresponding to the number information, detects the number information of the mobile terminal from among the received update information upon receiving the update information from the mobile terminal, and stores the resultant game score in the memory according to the detected number information.
