An observation system is a tool or method used in research to systematically observe and record behaviors, events, or phenomena in a specific environment. This system can be used in various fields such as psychology, education, sociology, and environmental science to gather data and analyze patterns or trends. Observation systems typically involve trained observers who use predefined criteria or measures to document what they see. This may involve direct observation in real-time, video recording, audio recording, or the use of specialized equipment such as cameras or sensors. The data collected through an observation system can provide valuable insights into human behavior, interactions, and environmental changes. Researchers use this data to identify trends, develop theories, and inform decision-making in various fields.
