Manual aiming research usually requires participants to aim a cursor to larger sized targets. To date, there are few instances where participants use an aiming apparatus larger than the target being aimed to, despite similar situations that occur throughout daily living. Researchers describe this relationship as "Tolerance", the difference between the aiming apparatus and the target. The present study set out to try to come to a better understanding about the target--cursor relationship. Participants were required to aim a 9mm cursor to five different sized targets, 3, 6, 9, and 12mm. Participants aimed to these targets in two different visual conditions. A full vision condition, where participants had vision of the cursor and target throughout the entire movement, and a partial vision condition, where vision was available throughout the movement until termination, where vision was occluded for 30% of the targets. Kinematic, temporal and correction data was collected to determine the control processes underlying this relationship and to better understand tolerance.
