Page 115 - The sky-earth background of the instrument face is attached to this gimbal ring and therefore tilts the gyro and horizon. Hence, the blue sky always remains above the horizon bar no matter how much the instrument or ship is tilted. The horizon bar is carried by a link from the rear part of the gyro casing through a pivot on the gimbal ring and thence out in front of the field as a light horizontal bar. The reason for this reversing linkage is that this corrects the horizon motion to the normal apparent...

A given knob was then presented to the blindfolded subject who felt it for 1 second. The experimenter then rotated the turntable to a predesignated point and the subject went from knob to knob, feeling each one in turn until he found and reported what he thought was the test shape. The same procedure was followed for each of the knobs, once...
