From: A new static visual field test algorithm: the Ambient Interactive ZEST (AIZE)
Example of visual field test step with AIZE. A prior PMF at (9,9) location (1) and (15,21) location (2). A stimulus is presented at (9,9) location, the prior-PMF is multiplied by a likelihood function (seen: red, not seen: blue) (3) and the prior PMF at (15,21) location is multiplied by a weighted likelihood which varies according to a distance from the tested location (4). A posterior PMF at (9,9) location is generated (5) and the PMF at (15,21) location is updated simultaneously (6). PMFs of other test locations in the A area are updated with the same manner.
