A little less obsessed.

By increasing the multiplier and decreasing the offset I’ve got the motivation providing much better coverage, it still does appear to get stick in certain areas. Following is a 2D histogram showing the pockets of density in certain areas:

Here is the same representation of data from the previous post for comparison:

An idea is to have the camera jump to a random position when it reaches the edges, and perhaps when it has spent too much time in one area, to provide better coverage. It is unclear how the non-evenly distributed gaze will manifest itself in the SOM. The increased frequency in particular “areas of interest” (to the motivation) should result in clusters in the SOM corresponding to those areas.
