Interface Origami  

Clever idea for physical interface mockups from Juan Sanchez. The image below demonstrates an interesting point about 1:1 interaction with digital interfaces though.

Notice how the interface element hasn’t been completely revealed and the thumb is already ‘off screen’. Concessions have to be made when a physical interface is translated over. Perhaps a threshold beyond which an action is automatically completed, or an accelerated rate of movement that breaks the 1:1 ‘sticky finger’ interaction model.

How those concessions are made, and how they are communicated to the user are important.
