uprightmodellen

Uprightmodellen is a term used in academic discourse to denote a conceptual framework for representing upright orientation in perception, cognition, and applied technologies. The core idea is to formalize how upright (vertical) orientation is distinguished from inverted or tilted configurations in data, tasks and behavior.

In perception and cognition, uprightmodellen refers to an assumed reference frame anchored to gravity, with orientation judged relative to vertical and horizontal axes. Experiments using the model investigate biases in judging uprightness, such as faster recognition of upright objects or easier matching of vertical orientations.

In robotics and computer vision, uprightmodellen guides algorithms for pose estimation, object recognition, and stabilization by defining an upright reference frame, thresholds for acceptable tilt, and rules for updating orientation under motion.

Variants of the model differ in how strictly upright orientation is defined: a strict version may require exact vertical alignment, while a probabilistic or context-dependent version allows tolerance based on scene cues or sensor noise.

Criticism notes that a single upright reference may overlook cultural and situational differences in what counts as upright, and that real-world perception can be flexible. Proponents argue that the model provides a practical abstraction for modeling gravity-aligned processing.
