The output of 3D volume segmentation is crucial to a wide range of endeavors. Producing accurate segmentations often proves to be both inefficient and challenging, in part due to lack of imaging data quality (contrast and resolution), and because of ambiguity in the data that can only be resolved with higher-level knowledge of the structure and the context wherein it resides. Automatic and semi-automatic approaches are improving, but in many cases still fail or require substantial manual clean-up or intervention. Expert manual segmentation and review is therefore still the gold standard for many applications. Unfortunately, existing tools (both custom-made and commercial) are often designed based on the underlying algorithm, not the best method for expressing higher-level intention. Our goal is to analyze manual (or semi-automatic) segmentation to gain a better understanding of both low-level (perceptual tasks and actions) and high-level decision making. This can be used to produce segmentation tools that are more accurate, efficient, and easier to use. Questioning or observation alone is insufficient to capture this information, so we utilize a hybrid capture protocol that blends observation, surveys, and eye tracking. We then developed, and validated, data coding schemes capable of discerning low-level actions and overall task structures.

This study investigates the symbolic function of these non-binary individuals through an analysis of 8 characters across four iterations of Star Trek, seeking connections between their fictional embodied meanings and how the role of real non-binary people is conceptualized today. I posit that the non-binary characters of Star Trek are portrayed dualistically, with those that are more ambiguous being portrayed as dangerous while those who possess easily gendered qualities are portrayed as benevolent and relatable. In the Star Trek universe, non-binary gender individuals are the "unknown" incarnate. Their identities, like non-binary people today, are continually parsed by the assumptions of a cisgender society-but through the performance of their gender identity, they find unity in liminality to begin reconcile the dual faces of their "self" which society sees and judges, but which they can only live.
