Now or Later: An Initial Exploration into User Perception ofMathematical Expression Recognition Feedback

Abstract

Mathematical handwriting recognition is an important method of mathematics input for computers. While strides in recognition have been made in recent years, recognition is still at a level where mistakes are common and often inexplicable from the user s point-of-view. As a result, recognition mistakes can cause user distraction andfrustration. We examine how user preference for real-time or batch recognition mode is affected by recognition accuracy and the number of expressions entered. Our results show that users prefer real-time recognition when working with multiple expressions; however, with high accuracy recognition, users did not prefer one recognitionmode over the other.
