Results are reported of laboratory experiments where levels of visual and tactile sensory input of human subjects are controlled and time required to assemble several types of devices is measured. There is an inverse relationship between the time to assemble a device and the amount of sensory input available to the subject. The results indicate that different types of assembly tasks require different types and amounts off sensory information processing. Another result is that the impact of a change in the level of tactile sensory input on assembly time depends on the available level of visual sensory input, and the nature of the interaction between visual and tactile information varies across the different assembly tasks. An analysis of the extent to which elemental manipulative subtasks as categorized by the Methods Time Measurement System are affected by changes in the level of visual and tactile sensory information is presented. Results are also reported of experiments where the levels of visual input and manipulative capability of human subjects are controlled. Originator-supplied key words include Experimental design.
