I thought I had written this in one of my previous posts but I guess I removed it because it was a different topic or something...
the access-button is very small, it is very good that its not obstructive, bigger button isn't the solution, but it often takes several tries to hit it. the most reliable way to access it for me is to swipe from outside the edge of the screen and pass through the access-button, but swiping along the edge or just clicking it is more problematic. maybe you can make the detection or something "smarter" somehow.

All of my main testing is done on an HTC Incredible and HTC Eris which are two phones that have a lot different touch sensitivity. I have found that per device, these settings need tweak...more so for swipe gestures. I will take another look at these settings... once I finish rewriting some code on how the popup is called, I can then put into place a few different ways to handle the click event.
Besides that idea, I also plan on having an auto hide (needs more thought)... but what this will allow is for a larger click zone. I can't make the button much bigger because then it will interfere too much with regular phone usage. Have you tried the button image called "Tab"? This is a larger button designed for a tablet...I'm just curious if you get better results from that.
Another thought I have ... which testing this is in my todo list ... is using the accelerometer. Half roll quickly to the direction oposite of the icon would show the popup or button(s), quick roll back..more of a snap twist :)
I have a Samsung Galaxy S on froyo not rooted. the tab image is not visible on black background (adding white background makes it look awful, maybe you can fix this?), I'm currently using the arrow image.
not too keen on the accelerometer idea myself but maybe if done the right way.
I just improved my experience by placing it in a corner, that way I can swipe from outside the screen in two directions :P ____ | | |↑ | || | -|x-->| |
Interesting. On my HTC Incredible aka bullet stopping life saver (recent news..ha), it handles multi-touch really well everywhere! If you have a moment I would be curious to see how your phone handles a test. On the market, there is a free download called Multitouch Visible Test from Battery Powered Games, LLC (friends of mine...woot). Some phones respond well, allow overlap multitouch, some allow some multitouch and some...just do not support it. This sometimes can give a good clue on how your screen handles gestures as well.

Using your diagram, I created my own really fast for you to try. When I use swipe, either swipe up or swipe down, I noticed that my thumb naturally wants to move off screen rather then going straight up.
Try this:
Configure for either side you prefer, for example..right side.
Swipe from the bottom x up and just a tad to the left and end at the second x.
This kind of feels like you are swiping that direction but really you end up swiping more in a straight line and prevents you from swiping off the screen to the right. More of a practice thing I guess. Make sure you change the swipe sensitivity as well to see if any improvements happen on high/med/low variations.
My Samsung Galaxy S phone handle five touch-points at the same time and the x,y lines go to about 1 millimetre from the edge of the screen, tracking simultaneous touch-points seems to work almost perfect except for the tiny offset caused by one touch-point affecting another. it is true as you say that, a little depending on how you hold the phone, naturally swiping with your thumb, most noticeably from bottom upwards tend to be in a slight arch, I will try different positions to see if my swiping get more accurate. a better idea I think would be to accommodate this, making swipes more ergonomic.
