The phrase "viewpoint tracking" is correct and usable in written English.
It refers to the act of monitoring and following someone's perspective or point of view on a particular topic or issue. Example: The journalist conducted thorough viewpoint tracking, interviewing various stakeholders and collecting data to accurately represent the diverse opinions on the controversial subject.
The primary contribution of the presented work is the design and implementation of a dynamic user-viewpoint tracking scheme in which mobile users' spatial context is defined not only by their position (i.e., location), but also by their three-dimensional head orientation (i.e., line of sight).
The ViewPoint Zebralab 'Tracking System' readouts demonstrated that the homozygous T70I sod1 zebrafish spent significantly more time (20%) in the bottom third of the tank, compared with their WT clutch mates (P<0.05; Fig. 5A).
If the viewpoint cannot be tracked, implementation of ray-based techniques [26] becomes problematic because the ray does not look like it is emanating from the wand.
Similar to the open-field test, the mice were placed in an open plastic chamber (45 cm × 45 cm × 45 cm) and allowed to move freely for 5 min, and their locomotor activities were monitored using a ViewPoint video-tracking system.
Interestingly, vaccine viewpoints don't track along traditional partisan lines.
From a practitioner viewpoint, there are now better systems for data management, tracking, devolving individualized programmes of study and for holding staff and learners to account.
However, the major difference with HMD's and CAVE systems is that interaction in front of a large display often involves more than one user (e.g. a presenter and an audience, or two collaborators) and that makes it problematic to track the viewpoint.
In an attempt to address fatigue in large display interaction, Katzakis et al. [26] proposed a set of techniques that allow manipulation by holding the wand at hip height, yet that work, like other ray-based work is hard to implement in a situation where the viewpoint is not being tracked or when it is necessary to interact from the skewed position of a presenter.
An immersive virtual environment is formed by a computer-generated surrounding real-time (stereoscopic) display of virtual sensory data from a viewpoint determined by the tracked position and orientation of the participant's head [7].
Free-viewpoint observation Users can freely alter the viewpoint of the camera, when it is controlled by frame-by-frame intermittent tracking.
