2. Descriptions of Related Art
Since the printing technique being invented by Johannes Gutenberg, human cultures have been recorded broadly and papers have played an important role in transfer of the knowledge. Reading is an important requirement needed for gaining information and knowledge. However, along with fast development of electronic technology, books are not the only source of knowledge. By Project Gutenberg founded in 1971, a plurality of literature whose intellectual property right have expired, or been forfeited have been digitalized in electronic form and available on internet to be download freely by readers. According to different types of media, information is transmitted in different ways. Through carriers such as internet, knowledge is distributed even more widely and effectively. Thus electronics such as electronic readers or electronic books have been developed for such purposes.
With the arrival of the digital era, digital resources have received more attention. The so-called digital resources means various information being digitalized, systematized and structured is read and utilized by users through different equipment. The digital resources include electronic books, electronic journals, paper database, electronic newspaper, etc. The electronic book is an important application of the digital resources. The invention and development of the electronic book represent a whole new field compared with books printed and published available now. Compared with conventional paper books, electronic books have advantages of elimination of print on paper and saving energy that takes during publication and production. Moreover, the electronic books have more file formats and this is helpful in spread and transfer of knowledge. In recent years, electronic books have played an important role on the book market. With the fast development and prevalence of electronic books, books in the electronic/digital form have become a mainstream. Yet it's also an important issue to learn the effects of such novel learning assistant tool (electronic books) on reader's physical and mental development. For example, if users use electronic readers or read electronic books for a long period of time, they will cause damages to eyesight. This is due to that most of new-generation electronic readers and electronic books have self-illuminating screens for showing content thereof.
In prior arts, refer to Taiwanese Pat. Pub. No. 201249402 “fatigue detection system and method thereof”, a system for detecting fatigue is provided. At a certain interval, a camera is controlled to take a photo of a user that uses a computer. Then the user's facial parameters are analyzed and obtained. When the facial parameters are not within the reference range of the user not tired, the user is reminded to take a rest. Refer to Taiwanese Pat. Pub. No. 201229776 “electronic reader and control method thereof”, a mechanism that detects fatigue in reading is revealed. While using electronic reader, a proximity sensor detects a distance between user's eye and the electronic reader to generate a distance sensing signal. The distance sensing signal is transmitted to a display control module so as to check whether the distance between the user and the electronic reader is over a preset value due to fatigue. Refer to Taiwanese Pat. Pub. No. M285339 “device for adjustment and amplification of crystalline lens”, a proximity sensor is provided to detect the distance between user's eyes and the book so as to remind the user of fatigue in reading. However, the devices disclosed above are unable to remind the user at proper timing according to the user's conditions of fatigue. Thus how to remind the user of fatigue in reading effectively for preventing the user from feeling more fatigue and protecting user's eyes has become an important issue for manufacturers of electronic readers or electronic books.
In order to solve the problems of conventional electronic readers or electronic books such as users can only be reminded of fatigue in reading at a certain interval and the electronic readers/books are unable to detect users' reading behavior or reading speed for reminding of fatigue in reading, there is room for improvement and a need to provide a novel device.
