Abstract

An electronic reader which includes a storage unit, and an input unit generating signals in response to user input. In addition, a processing unit detects the signals corresponding to the user input; controls the electronic reader to enter a reading mode, and displays a file according to the user input, records a length of duration time for which the electronic reader operates in the reading mode; determines the duration time and executes a variety of protective instructions and steps depending on the length of duration time for which the electronic reader operates in the reading mode. A control method is also provided.

Claims

1. An electronic reader, comprising:

a storage unit configured for storing electronic files;

an input unit configured for generating input signals in response to user input operations;

a display unit; and

a processing unit configured for;

controlling the electronic reader to enter a reading mode where the display unit is configured for displaying the electronic files in response to the input signals;

recording a length of duration time for which the electronic reader operates in the reading mode;

executing a first protective instruction if the duration time reaches a first preset time, and

executing a second protective instruction if the duration time reaches a second preset time, the second preset time being greater than the first preset time.

2. The electronic reader as claimed in claim 1, wherein the first protective instruction is selected from the group consisting of changing display property of characters displayed on the display unit;

and playing a reminding file to remind user to take measures to reduce fatigue.

3. The electronic reader as claimed in claim 1, wherein the second protective instruction is selected from the group consisting of changing display property of characters displayed on the display unit;

and playing a reminding file to remind user to take measures to reduce fatigue; and

suspending the display unit for a preset time period.

4. The electronic reader as claimed in claim 1, wherein the processing unit is further configured for executing a third protective instruction if the duration time reaches a third preset time, and the third preset time is greater than the second preset time.

5. The electronic reader as claimed in claim 4, wherein the third protective instruction is selected from the group consisting of changing display property of characters displayed on the display unit;

playing a reminding file to remind user to take measures to reduce fatigue, and suspending the display unit for a preset time period.

6. The electronic reader as described in claim 2, wherein the processing unit is configured for controlling the input unit to be unresponsive to input operations excepting a shutdown command when the display unit is suspended, and activating the display unit after a preset suspension time period is lapsed.

7. The electronic reader as described in claim 6, wherein the processing unit is further configured for restarting recording of the duration time after the display unit is activated.

8. The electronic reader as described in claim 1, further comprising a light detection unit configured for detecting ambient light intensity and a distance detection unit configured for detecting a distance between a user and the electronic reader.

9. The electronic reader as described in claim 8, wherein the processing unit is further configured for reminding the user if the distance between the user and the electronic reader exceeds a preset distance, and increasing the brightness of the display unit if the detected light intensity is lower than a preset light intensity.

10. A control method applied in an electronic reader, comprising:

detecting the input signals;

controlling the electronic reader to enter a reading mode wherein a display unit displays an electronic file in response to the input signals;

recording a length of duration time for which the electronic reader operates in the reading mode;

executing a first protective instruction if the duration time reaches a first preset time; and

executing a second protective instruction if the duration time reaches a second preset time, the second preset time being greater than the first preset time.

11. The method as described in claim 10, wherein the first protective instruction is selected from the group consisting of changing display property of characters displayed on a display unit;

and playing a reminding file to remind user to take measures to reduce fatigue.

12. The method as described in claim 10, wherein the second protective instruction is selected from the group consisting of changing display property of characters displayed on the display unit;

and playing a reminding file to remind user to take measures to reduce fatigue; and

suspending the display unit for a preset time period.

13. The method as described in claim 10, further comprising:

executing a third protective instruction if the duration time reaches a third preset time, wherein the third preset time is greater than the second preset time, the third protective instruction is selected from the group consisting of changing display property of characters displayed on the display unit; and

playing a reminding file to remind user to take measures to reduce fatigue; and

suspending the display unit for a preset time period.

14. The method as described in claim 13, further comprising steps of:

activating the display unit after a preset suspension time period is lapsed; and

restarting recording of the duration time after the display unit is activated.

15. The method as described in claim 14, further comprising steps of:

activating the display unit after a preset suspension time period is lapsed; and

restarting recording of the duration time after the display unit is activated.
