In this paper we present a robust 3D human-head tracking method. 3D head positions are essential for robots interacting with people. Natural interaction behaviours such as making eye contacts require head positions. Past researches with Laser Range Finder (LRF) have been successful in tracking 2D human position with high accuracy in real time. However, LRF trackers can not track multiple 3D hea...

UNLABELLED The aim of the present study was to compare the head position and dental wear of bruxist and non-bruxist children with primary dentition. METHODS All the subjects had complete primary dentition, dental and skeletal class I occlusion and were classified as bruxist or non-bruxist according to their anxiety level, bruxism described by their parents and signs of temporomandibular disor...

INTRODUCTION This study investigated the relationship between the parameters related to the natural head position and cervical segmental angles and alignment of patients with neck pain. MATERIAL AND METHODS The lateral radiographs of the cervical spine were collected from 103 patients and were used to retrospectively analyze the correlation between the natural head position, cervical local sa...

Despite decades of attempts to create a model for predicting gaze locations by using saliency maps, a highly accurate gaze prediction model for general conditions has yet to be devised. In this study, we propose a gaze prediction method based on head direction that can improve the accuracy of any model. We used a probability distribution of eye position based on head direction (static eye-head ...

OBJECTIVES Natural head position is recommended to be optimal at cone-beam computed tomography acquisition. For standardization purposes in control of treatment outcome, it is clinically relevant to discuss, if a change of posture from natural head position may have an effect on the pharyngeal airway dimensions and morphology, during computed tomography, cone-beam computed tomography or magneti...
