Anyone got the idea how the Chinese/english character/word reading pen is made ? I mean how the structure of the project ?
1) What kind of MCU and memory required ?
2) What is OCR library ? Open source or purchase library ?
3) Is all the electronics can be so small to keep inside the pens ?
4) Also there are reader as well. Means it can read out the word and explain the meaning....how this is done ?
