I have observed some people fumble with a mouse. They seem unable to synchronize clicking the buttons and sliding the mouse consistently, to where they drag things when they only meant to click on them. Or in trying to use drag-and-drop, they inadvertently drop too soon because they can't keep their finger on the mouse button for the whole travel. Or they have trouble aiming the mouse while keeping the button pressed.
The web application is a simple toolbar. Think stickers, like gold stars for favorites, or thumbs-down for disfavor, or a red X for deletion. I want users to be able to apply those stickers from a "toolbar" on the edge, to objects on a web page. Drag-and-drop works for this.
For less dextrous users I envision what I'm calling click-and-drop. Instead of dragging with the mouse button depressed the whole time, it proceeds like this: one full click (mousedown + mouseup) on the toolbar "picks up" the icon. Now the mouse-cursor is replaced by the icon while the mouse moves, possibly with a grabbing hand next to it. A second full click at the destination "drops" the icon and the mouse-cursor goes back to what it was. Is there a name for this already? Maybe that action is more like dipping a paintbrush in a watercolor well, rather than a tool-belt.
Would this click-and-drop alternative be helpful for a good portion of dexterity-challenged web users? Are there better alternatives?
Without muddying this question too much, I was further thinking this alternative might transport to mobile or pad devices. Touch the toolbar, the icon hovers say in the upper right corner, pan to the destination, tap the destination once to "drop" the icon. I bring this up mainly for the consideration of consistency across devices. Though perhaps an entirely different scheme is better for the multi-touch world.
