dc.description.abstract | This work deals with an e-dictionary pen which can translate an English vocabulary on the paper into a Chinese one and project it on the same place. Notice that, compared with the same products on the market, we present a low cost solution, also notice that we enhance user-friendliness and convenience.
The developed e-dictionary pen is functioned as scanning an English vocabulary on ink paper by an optical lens in front of the pen, transforming the read texts string into grey level images, and relaying the images to a smartphone via a Bluetooth interface embedded in the pen. Adopting the Optical Character Recognition(OCR) Application Programming Interface(API) within smartphones, text strings are recognized from the relayed images, translated into coded Chinese vocabulary, transferred into bitmap images, and sent back to the pen through the same interface. After receiving the bitmap images, e-dictionary pen will project it on ink paper.
It has shown that, in order to cut the cost of an e-dictionary pen, we eliminate all expensive components by making use of functions and databank of smartphones to process all required complex algorithms. It has shown that an e-dictionary pen is only an I/O device which results in friendly and convenient for users. | en_US |
