This study focuses on the use of computers in the field of education. It reports a series of experimental mouse move and click tasks on constant and moving stimuli. These experiments attempt to explore the efficiency with which individuals of different skill level and age group perform using a mouse. Differences in performance between high-skill and low-skill computer users on low-level mouse operations tasks are examined. Four experiments are employed, using special software, in an effort to tackle the practical issue of mouse use and its constraints for both adults and younger users. Results showed within-subjects variation in performance on mouse operation tasks. Performance differences among groups were also observed.
