I taped a piece of string to one of the Popsicle sticks to show the submenu structure. |
The simple line set is now a familiar symbol for interacting across-the-board with a site's submenu. |
On a PC, each heading opens a topic submenu, but these should be larger, since scrolling through dozens of choices in small windows is awkward and frustrating. |
For example, a fingertip could help select an object while a knuckle tap could act like the right-click on a computer mouse and open up a submenu. |
