ELECTRONIC-BOOK READER DEVICE AND NON-TRANSITORY COMPUTER-READABLE RECORDING MEDIUM HAVING STORED THEREIN A DISPLAY CONTROL PROGRAM
An electronic-book reader device includes a screen that displays a page image of an electronic book; a first sensor disposed on a side face of the electronic-book reader device; a second sensor disposed on a reverse face of the screen of the electronic-book reader device; a determiner that determines a rate of switching display of a plurality of the page images using an amount of input operation via the first sensor and an amount of input operation via the second sensor; and a display controller that carries out continuous page-turning display on the screen by displaying the plurality of page images being successively switched at the rate determined by the determiner. This configuration makes the reader possible to turn pages, feeling as if reading a paper-medium book.
1 . An electronic-book reader device comprising:
a screen that displays a page image of an electronic book;
a first sensor that is disposed on a side face of the electronic-book reader device;
a second sensor that is disposed on a reverse face of the screen of the electronic-book reader device;
a determiner that determines a rate of switching display of a plurality of the page images using an amount of input operation via the first sensor and an amount of input operation via the second sensor; and
a display controller that carries out continuous page-turning display on the screen by displaying the plurality of page images being successively switched at the rate determined by the determiner.
2 . The electronic-book reader device according to claim 1 , wherein the determiner increases the rate with increasing of a pressure difference between a first pressure detected at a first position closer to the screen on the first sensor and a second pressure detected at a second position closer to the reverse face on the first sensor, the first pressure being lower than the second pressure.
3 . The electronic-book reader device according to claim 1 , wherein the determiner increases the rate with increasing of an amount of moving an article being in contact with the first sensor from a third position closer to the screen to a fourth position closer to the reverse face.
4 . The electronic-book reader device according to claim 1 , wherein the determiner increases the rate with increasing of a pressure detected by the second sensor.
5 . The electronic-book reader device according to claim 1 , further comprising a third sensor that detects an acceleration of the electronic-book reader device, wherein
when the acceleration detected by the third sensor exceeds a threshold while a value detected by the first sensor and a value detected by the second sensor do not satisfy a condition to start the continuous page-turning display and the continuous page-turning display is stopped,
the display controller carries out turning of a single page of the electronic-book by displaying the page image being switched by one page of the electronic book.
6 . A non-transitory computer-readable recording medium having stored therein a program for display control causing a processor included in an electronic-book reader device to execute a process comprising:
displaying a page image of an electronic book;
determining a rate of switching display of a plurality of the page images using an amount of input operation via a first sensor that is disposed on a side face of the electronic-book reader device and an amount of input operation via a second sensor that is disposed on a reverse face of the screen of the electronic-book reader device; and
carrying out continuous page-turning display on the screen by displaying the plurality of page images being successively switched by at the determined rate.
7 . The non-transitory computer-readable recording medium according to claim 6 , the process further comprising:
increasing the rate with increasing of a pressure difference between a first pressure detected at a first position closer to the screen on the first sensor and a second pressure detected at a second position closer to the reverse face on the first sensor, the first pressure being lower than the second pressure.
8 . The non-transitory computer-readable recording medium according to claim 6 , the process further comprising:
increasing the rate with increasing of an amount of moving an article being in contact with the first sensor from a third position closer to the screen to a fourth position closer to the reverse face.
9 . The non-transitory computer-readable recording medium according to claim 6 , the process further comprising:
increasing the rate with increasing of a pressure detected by the second sensor.
10 . The non-transitory computer-readable recording medium according to claim 6 , the process further comprising:
when an acceleration detected by a third sensor that detects the acceleration of the electronic-book reader device exceeds a threshold while a value detected by the first sensor and a value detected by the second sensor do not satisfy a condition to start the continuous page-turning display and the continuous page-turning display is stopped,
carrying out turning of a single page of the electronic-book by displaying the page image being switched by one page of the electronic book.
