I am experiencing that it needs several hits on a left or right arrow key to move from one picture to the next. This is not a consistent issue. Any clues?

This is what I was talking about in this discussion: "Usability Bug: The quickest tap of a 'Next' key needs to reliably advance one photo."

I know you know this already, Joscelin, but for newer users' sake, note that in some synths (like Walks or vertical Walls, Spins, or Pans) you would use the up or down arrows instead of the left and right and that this issue would still be a factor in those cases.

The Photosynth team's answer so far is that when the pattern of photos does not conform to the synth shape specified that it can become difficult to reliably take you to the next image in the sequence.

I linked to an extreme example for illustration but it was dismissed as an edge case when I had made clear in my post that the issue was affecting normal synths as well.


On one hand, it is fair in some cases to criticize the photographer for taking a set of shots which loop back on themselves in a way that doesn't conform to the synth type and the Photosynth viewer automatically chooses the nearest photos to the smoothed path through the photos (sometimes skipping photos which are too far behind or in front of the smoothed path). 

Since the arrow keys are digital inputs but are being used to control analog movement (the speed of the viewport accelerates from slow to top speed the longer the cursor key is held down), you must hold down the cursor key long enough to get you more than 50% of the distance to the next camera frustum to successfully snap to it.

On the other hand it is not unreasonable for a user to expect to be able to advance or regress one photo.

Right, the original shooting was for Photosynth 1. Consequently, not everything was shot in a clear path, as this was not a requirement for Photosynth 1. I am in the process of breaking down yet another Photosynth1 experiment project. 

Thanks Nate.
