MathCamera is a fun math tool (or toy) I developed for my kid. Basically, this application can "read" and "solve" common math calculations form math workbook, test sheet, or anything which Android smartphone camera can "see" in real-time.The current version of MathCamera is only a demo copy. It only includes an ultra light-weight OCR (Optical Character Recognition) engine. For better test experience, please download the tested math work sheet from:http://togosoft.com/android/mathcamera/mathtest.pngFinally, hope everyone likes the idea of this application. Thanks.
