A properly calibrated display enables a driver to more easily and accurately see the track ahead, as well as see the true placement of track side objects like trees, curbs, hay bales, etc. that may very much influence driver inputs while racing.
The benefit of proper calibration is confidence that car setups and car performance is in response to the track and not compromised by a distorted view.
If the display is out of sync, a user may think the car is turning in too quickly, or not quickly enough, seeming to understeer or oversteer. They may miss brake points or have difficulty setting brake bias when actually it is driver perception errors that are being misdiagnosed as setup and driving errors.
How to use the Skid Fun Cauldron of Fire Driver View Display Calibrator:
Drive up to the cauldron and find the 50-Meter line. It is the first white line away from the cauldron and it is labeled 50M.
Drive around until you find the pit girl with the checkered flag. Notice that beyond her on the far outside ring is another pit girl, (that appears at that distance to be a small vertical line on the horizon).
Imagine a line on the track from the far away pit girl to the checkered flag pit girl that extends behind you past the 50-meter line. Park the car on the 50-meter line so the in-car driver's head is over the intersection of the two lines, facing the checkered flag pit girl at a tangent to the cauldron.
From this position, the angle between the in-car driver head and the two outside pit girls to the left and right is 42-degrees, (the calibration angle), as shown below in Bob Simpson's drawing.
Calibrate user view by adjusting FOV until the calibration angle from your eyes to the pit girls is equal to 42-degrees.
To do this, use a protractor as a calibration tool by placing it on the bridge of your nose and hold it level in front of the display. Or using a protractor, cut a piece of heavy paper so two edges make a 42deg angle...easier than trying to read a protractor from an inch or so away.
If the left and right side pit girls are inside 42degs on the calibration tool, reduce FOV until the lines from your eyes align with the 42deg lines and point to the pit girls.
If the left and right pit girls are outside 42degs, increase FOV to bring them closer together, until the lines on the calibration tool point to the pit girls.
This is a new Skid Fun feature of uncertain practical utility.
It is not tested by a team of beta testers, so early adopters are the beta team and are welcome to comment on any results.
