External visual working memory

External visual working memory (EVWM) refers to technology that gives a person ability to perform cognitive tasks to a greater extent than with only a brain using storage of visual representations outside the brain. It includes technology like paper and pencils and computers.

In a 3D electronic interaction system, EVWM consists of a combination of a display and electronic memory like dynamic random-access memory (DRAM).

Background

In general, humans' biological working memory is limited in capacity and duration, and cannot hold more than a few items at once without active rehearsal.

Some individuals have much greater visual working memory capabilities.

It provides a key interface between perceptual processes and higher-level cognitive processes.
