headcentric
Headcentric, or head-centric, is an adjective used to describe systems, models, or perspectives that use the head as the reference point for spatial orientation, perception, or control. In practice, headcentric denotes a coordinate or reference frame anchored to the head’s position and orientation, as opposed to other frames such as eye-centered or body-centered. The term appears across disciplines to discuss how information about space is encoded, transformed, or acted upon when the head is the primary reference.
In neuroscience and psychology, head-centric representations are contrasted with eye-centered representations. Neurons may code spatial location
In human-computer interaction and virtual or augmented reality, head-centric input leverages head-tracking data to control navigation,
In robotics and computer vision, head-centric coordinates are used when a robot or wearable camera system uses
