Evaluation of intelligent input interface for entering equations on smartphone

Current input interfaces for entering equations on mathematics e-learning systems are cumbersome, especially for novice learners. In addition, most equation editors are not developed for use in smartphones. Our goal is to develop an intelligent mathematical input interface for smartphones based on a math input method that allows users to input mathematical expressions by using colloquial-style linear strings. This paper presents an evaluation of our proposed input interface. The results show that proposed input interface allows mean was approximately 1.3 times faster than the standard interfaces.
