Modeling human performance of pen stroke gestures

  title={Modeling human performance of pen stroke gestures},
  author={Xiang Cao and Shumin Zhai},
This paper presents a quantitative human performance model of making single-stroke pen gestures within certain error constraints in terms of production time. Computed from the properties of Curves, Line segments, and Corners (CLC) in a gesture stroke, the model may serve as a foundation for the design and evaluation of existing and future gesture-based user interfaces at the basic motor control efficiency level, similar to the role of previous "laws of action" played to pointing, crossing or… CONTINUE READING
