A computer based method to record three-dimensional body postures
… to allow users to select and manipulate limb postures from one of six different views (left, right, front, back, top, and three-dimensional). The separate views are coordinated to force a consistent representation for later analysis or storage. Human factors concepts have been incorporated …

The impact of head and body postures on the acoustic speech signal
… the influence of five head positions and three body orientations on the acoustic speech signal. Results show that there is a consistent change in the third formant, a change which was most evident in the body orientation measurements, and to a lesser extent in the head position data. Analysis of …

Ambulatory measurement of body position
… pressure and ECG waveform can change because of body position. In the case of the ECG, the changes caused by body position are can change the ST-T segment and also the QRS amplitude. The heart rate and blood pressure changes when there is a change in position from standing to sitting, sitting to …
