Design Team/Activity Touch Input

Calculate

• Prevent auto expose of on screen keyboard for calculation entry widget and rely on canvas and toolbar buttons
• Manual reveal of keyboard for some more advanced actions
• Cursor left/right canvas buttons
• Backspace canvas button
• Scientific vs. Basic canvas display toggle (not essential but would improve touch experience)
  • Major toolbar reword/reduction
  • Most functions get canvas buttons in scientific mode
• New implementation of help

Labyrinth

• Canvas zooming in/out with pinch gesture
• Canvas scrolling when dragging canvas (replace current behaviour of creating a node of a specific size, rely on single tap to create a node)

Read

• Vertical scrolling solution
• Page turning swipe gesture for paginatable documents

Terminal

• Add warning confirmation alert strip to 'Become root' button to provide feedback
• Will require a close to full feature on screen keyboard with modifiers and unusual characters
• Update tab design as per Browse to provide larger hit targets
• Drag scrolling
• More accurate text selection (system wide solution needed for touch)
• Drag scrolling through console history

Turtle Art

• Canvas zooming in/out with pinch gesture

Right now, there is no canvas zooming at all... just block zooming.

• Canvas scrolling when dragging canvas

Will add to v138 (See commit at [1]).

• Default to large blocks when used on a touch device to reduce obscuring effect of fingers & improve hit target. Perhaps extend the block shapes to have an otherwise blank 'gripper/ridged' area to the left or right

What is the purpose of the gripper?

To allow a fat finger to easily drag a block about without obscuring its content and top edge for snapping onto other blocks

Got it. It could be something that only appears on a touch-enabled machine (or when the XO is in tablet mode). I'll sketch something up.

• Portrait orientation clips too many toolbar icons (expect portrait orientation to be used much more frequently on tablet devices)

As of v137, there is a scroll mechanism for clipped palettes...

• Toolbar hover hints clobbering view of block palettes (due to touch activation leaving pointer over toolbar buttons )

These can be turned off and could be by default.

• Allow escaping from full screen mode (see Read for improved behaviour)
• All Save as/Export options should raise a confirmation alert to provide user feedback of Journal entry creation.
