Accommodation response during a prolonged visual search task.
The visual accommodative response is measured during dark field viewing and while engaged in a visual search task. A laser optometer is used to compare performance using microfiche and hard-copy displays. Results indicate a marked bias in the direction of the individual's resting accommodative state during all conditions of display viewing. Implications of these results and those from other studies are discussed with respect to future research in display design.
