Hi all,
Just wanted to note a use-case related to pointer/touch target size:
Point scanning in switch access modes (on iOS[1] and Samsung Galaxy S6).
- lets you select an item on the screen by pinpointing it with scanning crosshairs (see screenshot).
- as opposed to Item Scanning (which lets user scan between programmatically identified targets)
- this mode is helpful for some switch users when there are lots of targets on the page or there are targets that for some reason aren't programmatically identified.
- there is a balance between scanning speed and accuracy - user wants to set a high scanning speed to get across the screen quickly, but then it is harder for them to target small targets.
