A procedure to determine the individually comfortable position of visual displays relative to the eyes

Article Abstract:

During an intervention 38 visual display unit (VDU) operators used four different screen positions to determine the advantages and disadvantages. There was more reported strain with screens at around 66 cm, compared to those at around 98 cm. Operators later chose their own most comfortable screen position, and changes due to intervention were observed, with some subjects choosing shorter distances and others choosing longer distances.

Impairments of manual tracking performance during spaceflight are associated with specific effects of microgravity on visuomotor

Article Abstract:

An attempt made to re-analyse tracking data of a cosmonaut to determine whether the tracking movements reveal the same kind of microgravity effects on motor control as were apparent in rapid aiming movements performed with the same hardware by the same cosmonaut is presented.
