Re: (TFT) I got 3 TFT(ish) modules for $20 ! - and Happy Halloween

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


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
