Newer design of close-up computer monitors increases ease of use

wearing the binocular head display.

Seated subjects were asked to rotate their heads several times to the left and right, and again up and down. They performed the same task while standing. They were also asked to rotate their head while sitting and while standing.

"Motion-related symptoms were a large problem in previous studies," Sheedy said. "Participants didn't have much problem with motion sickness in this study, probably due in part to the nature of the tasks they were asked to perform.

"Most of the previous studies on near-eye displays used video movement or virtual reality tasks that created movement on the virtual display. These kinds of tasks are more likely to cause queasiness."

Nor were the participants in the current study fully immersed in the image. That is, neither the monocular nor binocular displays blocked the user's peripheral vision, so he could focus on the image in front of him and still see his surroundings.

"Being able to see the real environment while wearing a display gives the user a visual reference that can help lessen confusion when the eye sees the image move," Sheedy said. "For most of the common uses, the user wouldn't want to be fully immersed in the virtual environment."

Although several prototypes exist, near-eye displays have yet to become common. It's only a matter of time before they do, Sheedy said. He doesn't see such devices becoming a
