Yes it is my very first post. I'm a graduate student working on a research project studying gestural/multi-touch interface accessibility for people have dexterity challenges.
I've looked over the massive forums trying to find mention of problems but i have been unsuccessful. So, i am reaching out and asking the question to see what kind of responses i get.
I have some mobility problems, and yes, I've found some difficulty with using the touch interface, and imagine that people with more extensive mobility issues would have correspondingly more problems.
The most serious difficulty I've encountered so far is inadvertently deleting things with the "swipe to get the delete button, then tap to delete" feature. I would inadvertently swipe while trying to tap an item to activate it, then tap it before I can stop myself. Poof! No more item.
🙁
I also have to try several times before activating features that require double-tapping in order to activate. I also find myself missing the mark quite often and tapping things next to the button/link I was trying to hit. It's usually not too difficult to back out or undo the results of inadvertent taps, but sometimes, I end up doing something I can't undo. Gestures that require more than one finger are also quite awkward for me and I find myself avoiding functions that require me to do that.
Using a stylus can help me be more accurate in hitting my intended target, but I haven't successfully double-tapped with a stylus. (In other words, it's harder to double-tap with a stylus than with my finger.)
Good luck with your research, it's good to know people are studying how to make things more usable for everybody.
