Stationaryonly

Stationaryonly is a term used in technical discussions to denote a constraint or mode in which only stationary elements, references, or states are considered or permitted. The word combines stationary with only, signaling a deliberate exclusion of movement or change.

In robotics and computer vision, stationaryonly often refers to systems that operate under the assumption that the scene is static. For example, cameras may be fixed, objects are not expected to move, and algorithms rely on a non-moving background. In user interface design, it may describe layouts and transitions that remain fixed relative to the viewport, with no parallax or animated motion.

In software engineering and data management, stationaryonly can describe data structures, memory layouts, or processing pipelines that preserve fixed references, avoiding relocation or dynamic resizing. The concept is used to improve predictability and cache locality in static plugins, simulations with fixed reference frames, or tests that rely on immutability.

The approach has limitations. It can hamper adaptability in dynamic environments and may constrain functionality when movement is intrinsic to the system’s purpose. Proponents argue it reduces complexity and increases reliability in static contexts, while critics note that real-world scenarios rarely remain entirely stationary.

Because the term is used implicitly across fields rather than as a formal standard, definitions and applicability vary. Related concepts include stationary reference frame, fixed-layout processing, immutability, and motion detection.
