Reach/Grasp Times with Lateral Reach Obstructions.

When moving to grasp an object having adjacent obstacles that limit the space available for placing the fingers, the time for the reach/grasp is dependent on the distance of reaching and the space available for finger placement. Here we model the time taken in terms of these variables and develop mathematical models for the reach and grasp phases of the task and the location of obstacles. Data show that the movement to the target may be made under visual control and that, when the obstacles are close to the target object, a visually-controlled movement is made that is modeled by a modified form of Fitts' law.

Factors influencing the career interest of medical graduates in obstetrics and gynaecology in Hong Kong: a cross-sectional questionnaire survey.
