It forms an important method of analysis in cognitive ergonomics to analyze the performance of a user and identify the potential problem areas in using a device or application. TYPES There are many and varied observational techniques, Direct – In this method the observer notices the task performed by the user. The user could be aware of this. Indirect - In this method the observer could be analyzing and observing the user without the user’s knowledge or with the help of an external tool like video, photographs etc. Participant observation – In this method the observer performs the task or work under consideration.
