Abstract
A human simulation model was created that estimates potential locations of a notebook computer display and keyboard. The simulation model effectively addresses human anthropometric, postural, and visual preference variability. Simulation output yielded ranges of movement for a display adjustment mechanism that accommodates a potential user population while allowing for acceptable working postures. Human-subject work established postural regressions for the simulation model, validated methodology used to create the model, and determined the simulation accuracy. Simulation output of display adjustment ranges was compared against real adjustability distributions established during the human subject work. A notebook display design mechanism that implements such horizontal, vertical, and tilt adjustments should help to reduce ergonomic stressors associated with notebook computing. The research promotes the effectiveness of utilizing human simulation modeling during product development.
