Question One – Summary

2 Nov

Performance load is a term used to describe the amount of physical or mental energy used to perform a task. In modern society it is a common goal to keep the performance load to a minimum, so companies try to outdo each other in creating something with the lowest performance load. There are two types of performance load, cognitive and kinematic.
The amount of the load imposed on working memory is called the cognitive load. (Chen, I., Chang, C. 2009). In other words, cognitive load is the level of ‘mental energy’ required for processing information when completing a task. (Cooper, G. 2002).
Kinematic is the degree of physical activity in which it takes to perform a task.  (Lidwell, W., Holden, K., Butler, J. 2003). The aim is to keep the amount of the kinematic load to a minimum as it will be easier for the person using the product or program.
