Recognizing Head Movement [PDF]

open access: yes, 2001
Previous studies have provided logical representations and efficient recognition algorithms for a simple kind of "minimalist grammars." This paper extends these grammars with head movement ("incorporation") and affix hopping. The grammars are presented as lexicons together with CKY-like reduction rules, so an efficient CKY-like recognition method is ...

Quantifying neck muscle activity during head fixation in VR

open access: yesFrontiers in Virtual Reality
IntroductionHead-mounted displays (HMDs) are central to virtual and augmented reality (VR/AR) experiences, yet their reliance on head movement for interaction imposes physical demands on the neck.

Nonverbal synchrony of head- and body-movement in psychotherapy: different signals have different associations with outcome

open access: yesFrontiers in Psychology, 2014
Objective: The coordination of patient’s and therapist’s bodily movement – nonverbal synchrony – has been empirically shown to be associated with psychotherapy outcome. This finding was based on dynamic movement patterns of the whole body.

Feed-forward and feedback projections of midbrain reticular formation neurons in the cat

open access: yesFrontiers in Neuroanatomy, 2014
Gaze changes involving the eyes and head are orchestrated by brainstem gaze centers found within the superior colliculus (SC), paramedian pontine reticular formation (PPRF), and medullary reticular formation (MdRF). The mesencephalic reticular formation (

A stabilized adaptive appearance changes model for 3D head tracking [PDF]

open access: yes, 2001
A simple method is presented for 3D head pose estimation and tracking in monocular image sequences. A generic geometric model is used. The initialization consists of aligning the perspective projection of the geometric model with the subjects head in the
