Tobii Studio analysis tips on scenes and segments
There are two small but useful features in Tobii Pro Studio that make it easier to define scenes and segments with high precision.
Another option is to use the Generate button and Segment. This way you can input the exact start and stop of your segments, based on events that occurred during the recording. If there aren't any other useful events, you can use the Tobii Pro Coding Scheme to create your own events.
