The normal human visual field extends to approximately 60 degrees nasally
(toward the nose, or inward) in each eye, to
100 degrees temporally (away from the nose, or outwards), and approximately
60 degrees above and 75 below the horizontal
meridian.[citation needed] In the United Kingdom, the minimum field
requirement for driving is 60 degrees either side of
the vertical meridian, and 20 degrees above and below horizontal. The macula
corresponds to the central 13 degrees of
the visual field; the fovea to the central 3 degrees.
Note that the angle between two hex vertices is 60 degrees.
Through experience in the early days of film innovation, it was determined
that a frame rate of less than 16 frames per
second (frame/s) caused the mind to see flashing images. Audiences still
interpret motion at rates as low as ten frames
per second or slower (as in a flipbook), but the flicker caused by the
shutter of a film projector is distracting below
the 16-frame threshold.
Modern theatrical film runs at 24 frames a second. This is the case for both
physical film and digital cinema systems.
Assuming a Figure perception rate of 1/20th of a second per perception
moment there are 100 perception moments per 5
second turn. Of course, the higher a Figures IQ the more perception moments
per turn available.
Purpose. To define reference values for head-cervical range of motion (ROM)
in healthy young adults, to assess the
effect of sex, and to quantify the separate contribution of other body
districts.
Methods. Thirty women and 30 men performed maximal head and cervical spine
flexion-extension, lateral bending, and axial
rotation. Movements were detected using a digital optoelectronic instrument.
Maximum head-cervical spine and thoracic
motions were separated.
Results. Flexion and extension were performed mainly in the sagittal plane.
The movement was larger in women (1360) than
in men (1300). During flexion, both sexes moved the head-neck and the thorax
in the same direction. During extension,
men moved only the head-cervical spine, while women moved the two analyzed
districts in the opposite directions. Lateral
bending was nearly symmetric, associated with head-cervical rotation and
extension, and larger in women (910) than in
men (770). Adjunctive thoracic motion was limited in the sagittal and
frontal planes, but larger in the horizontal plane
(opposite motions of about 200). Head-neck rotation was symmetric, and
associated with concomitant movements in both the
sagittal and frontal planes. It was larger in women (1620) than in men
(1550), and performed with limited adjunctive
thoracic motions.
Note that at over 120 degrees of RoM a Figure can easily turn it's head to
face the center of any of it's front hexes
(changing the Figures side and rear hexes).
This study was undertaken to test the predictive value of two selected
muscular coordination mechanisms, the sequential
order of muscle activation and a specific acceleration-deceleration point of
inflection, and of the maximum static
strength of agonist and antagonist muscles for maximum speed of human
movement. For 22 male subjects 77% of the variance
associated with maximum speed of human movement was accounted for by the two
mechanisms of muscular coordination
investigated and by maximum isometric strength. The results suggest that
separate neuromotor systems control human speed
and strength and that the interplay between agonist and antagonist muscles
is important for maximum speed of human
movement.

Human movement, even fast human movement is predicted to have a maximum
frequency of around 250 hertz. This suggests
that even for the fastest human movement (not including equipment such as
the golf club or tenis racket, which will move
faster) 250 frames per second capture speed will be enough
