Higher Mathematics Sign Language Interpreter

One of the important problems observed in society is that the deaf mutes are finding it hard to cope up with the fast growing technology. The aim of proposed topic is to introduce new sign language gestures for higher mathematics. It also focuses on design of portable interpreting device which convert this maths sign language into corresponding text and voice. The flex sensors are used to identify the gesture. The change in resistance across each flex sensor is recorded as high or low resistance for each finger position. Arm Cortex M3 is used to process this data. Total 13 alphabets, 9 digits, 13 maths notation notations and 17 trigonometry identities are successfully interpreted by the module.
