Advantages and Disadvantages of Video and Live Observation
| Video Observation | Live Observation | |
| Advantages | - temporal resolution can be increased by pausing the video | - instantaneous access to information and possibility to ask for hidden information, e.g. surgical decisions |
| - knowledge acquisition can be repeated, if the structural ontology or the content ontology need to be altered | - dynamic repositioning of the observer in the OR, e.g. if line of sight is blocked | |
| - workload of the observers is less than in live observations | ||
| Disadvantages | - not all information for the SPM can be captured on video | - loss of information due to distraction or increased workload of the observer |
| - field of view can be blocked by intervention participants | - limited temporal resolution | |
| - high costs of time for data acquisition |
