The reading pen uses a technology called "optical identification technology" (OID), which can be understood as an identification method. Applying this technology to education and learning can be seen as the result of integrating education with technology. This technology combines precision optical processing with efficient digital signal processors, MP3 technology, and flash memory.
OID resolution spacing is 0.5mm × 0.5mm. The identifiable object can be of any size and shape. The storage component can be expanded using external flash storage, SD cards, and more. OID features a wide reading angle, fast response speed, low power consumption, and thus a compact size. It has practical applications in language learning, tutoring, interactive courses, point reading, storytelling, music, commercials, audio guide maps, and more.
You can use the reading pen to directly read any part of a textbook; you can point to corresponding animated stories, dialogues, and music in an animation book; you can indicate scenic routes and content introductions on a guide map; and you can point to product audio descriptions on product text. You can also listen to MP3s for leisure at any time.
