A fuzzy rule-based approach to recognizing 3-D arm movements

One particular application of gesture-based systems is to implement a speaking aid for the deaf. For this to happen, it requires a module that can recognize three-dimensional (3-D) arm movements since arm movement is one of the four main attributes characterizing a sign word. In this paper the authors propose a fuzzy rule-based recognition method. The effectiveness of this system is evaluated by recognizing 3-D arm movements involved in Taiwanese Sign Language (TSL).
