Compensatory and orienting eye movements induced by off-vertical axis rotation (OVAR) in monkeys.
Nystagmus induced by off-vertical axis rotation (OVAR) about a head yaw axis is composed of a yaw bias velocity and modulations in eye position and velocity as the head changes orientation relative to gravity. The bias velocity is dependent on the tilt of the rotational axis relative to gravity and angular head velocity. For axis tilts <15 degrees, bias velocities increased monotonically with i...
متن کاملVerticality perception during off-vertical axis rotation.
During prolonged rotation about a tilted yaw axis, often referred to as off-vertical axis rotation (OVAR), a percept of being translated along a conical path slowly emerges as the sense of rotation subsides. Recently, we found that these perceptual changes are consistent with a canal-otolith interaction model that attributes the illusory translation percept to improper interpretation of the amb...
متن کاملEye movements during multi-axis whole-body rotations.
The semi-circular canals and the otolith organs both contribute to gaze stabilization during head movement. We investigated how these sensory signals interact when they provide conflicting information about head orientation in space. Human subjects were reoriented 90 degrees in pitch or roll during long-duration, constant-velocity rotation about the earth-vertical axis while we measured three-d...

متن کاملAn Elegant Intuitive Algorithm for Rotation about a Mobile Axis
Rotation Transformation is the backbone of visualization of 3D objects. Rotation transformations allow viewing objects from different angles. Rotations about the principal axes are straightforward whereas the rotation about an arbitrary axis is complex. In mobile environment, rotations is computed continuously as the objects move and is thus a costly operation. We give intuitive, constructive, ...
