Review of models for restricted-path movements

Many tasks involve movement through lateral constraints. Examples are driving along a narrow path, moving a fork-lift truck through corridors, wheeling a patient down a hospital corridor, tasks in industrial assembly, machine sewing within given accuracy bounds and controlling a mouse or other pointing device in computer operation. This paper reviews the various models that have been proposed that may allow prediction of times for such tasks. In particular, the paper considers the model of Drury [1971. Movements with lateral constraint. Ergonomics 14.2, 293-305] and the various experiments arising from the development of this model.
