The mobile terminal 100 starts the e-book application (S410). The touch screen 151 of the mobile terminal 100 receives a user action for a quick look operation on the e-book content (S420). The controller 180 of the mobile terminal 100 analyzes the input user's motion (S430). The controller 180 of the mobile terminal 100 determines the quick look operation according to the analysis result (S440). The touch screen 151 of the mobile terminal 100 displays the e-book content according to the quick look operation determined under the control of the controller 180 (S450).

E-book content can be used in the present invention because the mobile terminal 100 has an e-book function or an application. The e-book function is used to read, view, and listen to the contents of a work published as a book or that can be published on electronic recording media and storage devices using digital data, and then through a wired or wireless information communication network using a computer or a mobile terminal. Function, and e-book content means a digital book that can be seen and heard using the e-book function.

The e-book industry has evolved rapidly, with improved screen resolution and a variety of editing features that allow users to turn pages with just a click, expand and reduce text as well as notes, search for documents in Internet bookstores and libraries, and download content.

It is also much cheaper than paper books, saves time through online purchases, and allows you to purchase only the parts you need. While reading, you can watch videos or listen to background music, and you can easily find the books you want anytime and anywhere by storing them on your PDA or portable device.

The e-book content that can be viewed through the mobile terminal 100 may be a file that is generally composed of text, but the e-book content may view a video file according to a function. In addition, depending on the content of the e-book, it is basically composed of a text file, but may include a video file.

The e-book content displayed through the touch screen 151 of the mobile terminal 100 may be stored in the memory 160 of the mobile terminal 100. The e-book content may be downloaded from an online market or an electronic library, or may be received through a personal computer through a wired or wireless interface. The e-book content thus downloaded or received is stored in the memory 160.

Meanwhile, the e-book content may be downloaded from an external server and displayed on the touch screen 151 instead of being stored in the memory 160.

The Quick Look operation used in the present invention means to quickly look at at least one page constituting the e-book content at a constant speed while the e-book content is displayed. In this case, the present invention may provide the effect of actually turning the page through the touch screen 151. When reading a real paper book, there is a case where the user glances through the book and flips pages quickly. The quick look operation of the present invention implements this on the mobile terminal 100.

The present invention is based on the premise that the mobile terminal 100 can display e-book contents. During the display of the e-book content using the e-book function, the controller 180 analyzes the user's motion when a user's action is defined as a quick look operation by the user.

5A to 5C, 6A to 6C, and 7 are diagrams illustrating prescribed user actions for the quick look operation.

First, FIGS. 5A to 5C illustrate a touch drag operation for initiating a quick look operation as an example of a user operation.
