The human processor model uses the cognitive, perceptual, and motor processors along with the visual image, working memory, and long term memory storages. A diagram is shown below. Each processor has a cycle time and each memory has a decay time. These values are also included below. By following the connections diagrammed below, along with the associated cycle or decay times, the time it takes a user to perform a certain task can be calculated. Studies into this field were initially done by Card, S.K., Moran T.P., & Newell, A. Current studies in the field include work to distinguish process times in older adults by Tiffany Jastrembski and Neil Charness (2007).

==== How To Calculate ==== The calculations depend on the ability to break down every step of a task into the basic process level. The more detailed the analysis the more accurate the model will be to predict human performance. The method for determining processes can be broken down into the following steps.

* Write out main steps based on: a working prototype, simulation, step by step walk-through of all steps
