In video analysis of movements, the result is impacted by, a) Condition of the Observer b) Content of the Object c) Equipment Used d) Entries shape This report will examine the impact of a) Condition of the Observer and b) Content of the Object which are two items difficult to control. Research Method: Experiment: Have multiple observers look at the same cooking movement and measure what percentage of the results match. Conduct Psychological Analysis of Observers: By conducting Uchida-Kraepelin Psychodiagnostic Test, the profile fluctuation can be measured and therefore the percentage of results that match can be estimated. With respect to the impact of Content of the Object, by setting correct parameters on what needs to be measured for each ADL, it is possible to secure high percentage of results to match. Conclusion: The reliability of video analysis can be secured by selecting Observers with high degree of accuracy and setting the correct parameters to measure.
