Abstract: A wireless terminal and a method of data communication between such wireless terminals includes a first wireless terminal determining whether a second wireless terminal is located within a preset distance, the first wireless terminal determining whether the first wireless terminal is tilted at more than a preset slope and the first wireless terminal transmitting a preset packet of data to the second wireless terminal where it determines that the second wireless terminal is located within the preset distance from the first wireless terminal and the first wireless terminal is tilted at more than the preset slope.

Abstract: The present invention relates to a bookmark setting method of an e-book, an apparatus thereof, and a medium storing program source thereof. The bookmark setting method includes: recognizing a user's operation performed on a touch screen while displaying the e-book; determining whether the recognized user's operation is an operation of folding a currently displayed subject page; and when the recognized user's operation is an operation of folding the subject page, setting the bookmark on the subject page according to predetermined criteria which in turn provides a realistic bookmarking experience as in the paper book.

Abstract: A portable terminal for and method of enlarging and displaying content are provided. The portable terminal includes a touch screen, a controller configured to cause the touch screen to display a first magnifying glass and a second magnifying glass wherein a part of the contents included in the first magnifying glass are enlarged and displayed by a first magnification ratio, a part of the contents included in the second magnifying glass are enlarged and displayed by a second magnification ratio, and a part of the contents included in an overlapping area where the first magnifying glass and the second magnifying glass overlap each other are enlarged and displayed by a third magnification ratio which is different from the first magnification ratio and the second magnification ratio.

Abstract: A wireless terminal and a method of data communication between such wireless terminals includes a first wireless terminal determining whether a second wireless terminal is located within a preset distance, the first wireless terminal determining whether the first wireless terminal is tilted at more than a preset slope and the first wireless terminal transmitting a preset packet of data to the second wireless terminal where it determines that the second wireless terminal is located within the preset distance from the first wireless terminal and the first wireless terminal is tilted at more than the preset slope.
