Use proper anatomical terminology to describe body regions, orientation and direction, and body planes. Fill in the blank with the proper directional term that best fits the comparison. The hip is on the surface. Fill in the blank with the proper directional term ...
rotation and translation, is also known as absolute orientation problem or equivalent Procrustes problem. A least square solution also exists based on a different formulation for rotation using quaternions [9]. The existence of a direct, fast and convergence guaranteed solution is practically desirable...
Body Planes, Directions, and Cavities JAMES VALLEY VOCATIONAL TECHNICAL CENTER
The location of the eyes is generally determined by tracking the head location and orientation. Knowing which direction the user is looking, however, requires further information. Technology for tracking the direction in which the user’s eyes are looking relative to their head has only recently be...

The 3D rotations discussed in the previous Section can be thought of as 4D rotations where the 4D rotation axis is given by the span of the usual axis in 3D and a vector in the direction of the 4th coordinate, the w-direction say. A rotation about the x y-plane would be given by ...
Clearly, it is a good idea to choose the orientation of xyz so that it lies in the principal direction. For every rigid body a principal direction exists. If a body has two or three planes of symmetry, the principal directions will be aligned with these planes. For the case where there...

It should be pointed out that the rigid body rotation rate for positive shear corresponds to motion in the decreasing Φ1 direction, with Φ and Φ2 remaining constant. This means that the orientation changes take place solely around the r or 3 axis of the specimen. It is evident from the...
planes of any crystalline structure can be specified usingMiller indices, which also serve to identifysingle crystalfaces. Miller indices are obtained by determining the intercepts of the plane with the unit cell axes in terms of the length of the cell in that direction, taking the reciprocal, ...
