Suunnannäköyksiköt

Suunnannäköyksiköt is a Finnish term formed from suunnan (direction), näkö (vision or sight), and yksiköt (units). The phrase is used in Finnish-language discussions of how people perceive and attend to different directions in space. There is no universally accepted definition, and the term tends to be descriptive and context-dependent rather than a standardized technical category.

Conceptually, a suunnannäköyksikkö can be understood as a discrete unit used to describe a particular direction in which visual attention or gaze is oriented, or as a target location that can be fixated. In theoretical frameworks, these units help map the relationship between perceived space and eye movements, enabling analysis of directional attention, spatial navigation, or interface interactions.

Operationalization typically involves dividing the visual field into sectors or angular bins, or designating specific possible gaze targets. Units can be counted, timed, or analyzed in terms of transitions between them. Measurement methods commonly employ eye-tracking to determine gaze direction, often supplemented by data on head or body orientation in immersive or real-world tasks.

Applications of the concept appear in usability studies, navigation aids, augmented reality, cockpit displays, and driving simulations, where understanding where a user looks informs design decisions. Limitations include variability in how boundaries between units are defined, which can hinder cross-study comparability. Overall, the term remains largely descriptive and auxiliary rather than a standardized technical category within Finnish scholarly writing.
