According to an exemplary embodiment, the electronic book reader 10 provides a learning function. The electronic book reader 10 may display a mask region on a screen thereof. The mask region comprises an opaque block or blocks for covering one or more objects of e-book contents displayed on the screen. These masks may be modified, released and/or moved. Examples of the objects of the e-book contents include characters and images. For example, in a learning process, the mask region is displayed to cover an answer to a question, and the user finds the answer to the question. When the mask region is released, the user may detect the answer to the question.
The mask region may be released in various ways. First, the mask region may be released by a single touch (a single tap). Secondly, the mask region may be activated as a writing window when being double-touched (double-tapped), and the mask region may be released when a text written by the user corresponds with the answer to the question. Thirdly, a voice recognition mode may be activated when the mask region is double-touched, and the mask region may be released when the user's reply corresponds with the answer to the question. The mask could also be released after an incorrect answer, or a predetermined number of attempts to answer the question correctly.
The mask region may be decorated in various ways. For example, the mask region may be decorated with an image.
FIG. 2 is a block diagram of an electronic book reader according to an exemplary embodiment of the present invention.
Referring now to FIG. 2, an electronic book reader 20 according to an exemplary embodiment of the present invention preferably includes a memory unit 21 for storing target data displayed, a display unit 22 for decoding the stored data to output an image signal, an input unit 23 for receiving a user input, and a control unit 24 for controlling an overall operation of the electronic book reader 20. The control unit 24 may recognize characters or voices, or a combination thereof, which will be described below.
When a mask region creation signal is generated from the input unit 23, the control unit 24 controls the display unit 22 to display a mask region. The mask region may vary according to the mask region creation signal. The mask region may be rectangular or elliptical. For example, when a touch moves in a touch region in an underlining manner, a mask region of a rectangular block is displayed to cover relevant words. The mask region may be a rectangular block having a diagonal line from a touch start point and a touch end point. Also, the mask region may be a closed region formed by a touch move path. That is, the mask region may vary in size and shape.
The control unit, which typically comprises a processor or microprocessor, controls overall operation of electronic book. A communication unit, which may be wireless and use an antenna to receive new subjects to be learned via the e-book, and possibly updates to the current items. Any wireless protocol including but not limited to CDMA, GSM, TDMA, FDMA or any similar protocol can be used, as well as Bluetooth, 802.11, WiMAX, WIBRO, WAP. Updates can also be downloaded via a USB port, etc.
When a scroll signal is generated from the input unit 23, the control unit 24 can control movement of the mask region, displayed on the display unit 22, in the corresponding direction. For example, when a scroll signal is generated to release the touch after the touch move, the control unit 24 controls the display unit 22 to move the displayed mask region to the touch end point. The mask region may be moved by moving a scroll bar provided in the touch region of the display unit 22. It is also within the spirit and scope of the invention that in an embodiment a stylus or pointing device can be used.
The control unit 24 releases display of the mask region when a mask region release signal is generated from the input unit 23. For example, the mask region may be released when the mask region is touched.
The control unit 24 preferably recognized characters. The control unit 24 may release the mask region when the inputted word is identical to the covered word. For example, when a word is covered with a mask region and a mask region release signal is generated from the input unit 23 by a double touch (a double tap) to the mask region, the control unit 24 activates a writing window in the mask region. The user may input a word as an answer in the writing window.
In addition, the control unit 24 may recognize a voice and convert the voice into characters. The control unit 24 may release the mask region when the inputted voice corresponds to the covered word. For example, when a word is covered with a mask region and a mask region release signal is generated from the input unit 23 by a double touch to the mask region, the control unit 24 receives and recognizes a voice together with a message for requesting a voice input to the mask region. Microphone/speaker unit 26 can receive the voice input, which can then be converted by a transducer and converted into an audio signal that is analyzed by voice recognition in the control unit.
FIG. 3 is a flow diagram illustrating a process of displaying, moving and releasing a mask region for learning in an electronic book reader according to an exemplary embodiment of the present invention.
Referring now to FIG. 3, in step 301, the control unit 24 determines whether or not a mask region creation signal is generated.
If the mask region creation signal is generated, the method proceeds to perform step 303. At step 303, the control unit 24 displays a mask region corresponding to the mask region creation signal.
At step 305, the control unit 24 determines whether or a scroll signal has been generated. If the scroll signal is generated, the control unit 24 proceeds to perform the action at step 307. At step 307, the control unit 24 moves display of the mask region in the corresponding direction according to the scroll signal.
At step 309, the control unit 24 determines whether or not a mask region release signal is generated. If the mask region release signal is generated, the control unit 24 proceeds to perform step 311. In step 311, the control unit 24 releases the mask region. The mask region release signal may be generated before or after the movement of the mask region. An example of FIG. 3 will now be described below with reference to FIGS. 4A to 8.
