We introduce a novel interaction technique using head motions to control the location of a window viewpoint within its document space. Head motion is acquired by a non-intrusive head-tracker using computer vision. The tracking technique used in the system, namely correlation matching, is described in order to exhibit its strengths and weaknesses in the context of tightly coupled interaction. Th...

Parapharyngeal space (PPS) is one of potential space of head and neck region and due to its hidden anatomical location, pathologies arising in this space are late to diagnose. This inverted pyramidal space was termed previously as pterygomaxillary space, lateral pharyngeal space and pharyngio-maxillary space. Parapharyngeal space is the current term that has come to stay because of indistinct i...

How does the visuomotor system decide whether a target is moving or stationary in space or whether it moves relative to the eyes or head? A visual flash during a rapid eye-head gaze shift produces a brief visual streak on the retina that could provide information about target motion, when appropriately combined with eye and head self-motion signals. Indeed, double-step experiments have demonstr...

A total of 152 pig farms were randomly selected from the five provinces in South Korea. During the experiment, the average temperature and relative humidity was 24.7°C and 74% in summer and 2.4°C and 53% in winter, respectively. The correlation between floor space allowance (FSA) and productivity index was analyzed, including non-productive sow days (NPD), number of weaners (NOW), survival rate...

When the head is unrestrained, rapid displacements of the visual axis-gaze shifts (eye-re-space)-are made by coordinated movements of the eyes (eye-re-head) and head (head-re-space). To address the problem of the neural control of gaze shifts, we studied and contrasted the discharges of omnipause neurons (OPNs) during a variety of combined eye-head gaze shifts and head-fixed eye saccades execut...

In this paper we present the affective message box, a dialog box that employs a real time head gesture recognition system as its input modality. Head nods and shakes correspond to “Yes/No” options on the dialog box. In addition, a confidence measure is inferred from a number of parameters extracted from gesture’s temporal patterns. While in current dialog boxes the input is either a definite ye...
