This involves creating a video file by recording a computer screen in order to capture the actions – such as mouse movement, clicks, window scrolling etc. – a person makes while using a website or application. Typically this would be while carrying out a series of tasks provided to them.
This video can be reviewed and actions can be compared between different people working through the same task to spot any part of the task that may be causing them a problem. One person failing to find information on a website quickly may not be a concern. Several people struggling to find the information is a clear indication that some re-design work needs to be done.
