I am designing a kiosk application that is intended to be used by people with very little computer knowledge or skills.
I want to allow the user to select a group of pictures to copy. Most of the time they will want to copy all of the items, but occasionally there may be one or two they do not want to copy.
The pictures will not have any good naming, so I want to use thumbnails instead of names.
My current design looks like this:
If the checkbox is selected, the image will be copied. If it is not selected, the image will not be copied. Clicking anywhere on the image frame will select or deselect the image.
My problems with this approach are that I am worried how intuitive this will be to people who are not that familiar with computers. I am also worried that people will try too hard to hit the tiny target of the checkbox when they can select the larger target of the whole frame.
Conversely people might get confused that accidentally clicking deselects the image. I think this can be mitigated by having a selected and unselected style for the whole frame - something like changing the background colour.
