title: Human movement characteristics of target acquisition.
abstract: Objective. This paper deals with the problem of human movement characteristics of target acquisition. Method. A hypothetical model was posed by using experimental data. Result. The conception of final target size was put forward, an equation for calculating the movement time of target acquisition was obtained, and a new definition of index of difficulty was given. Conclusion. Analysis of experimental data showed that this equation could give a better description of target acquisition in a wide range.
