Each valid target icon in the direction of the drag motion creates a linked tip icon that approaches the dragged object

Drag-and-pop and drag-and-pick are interaction techniques designed for users of pen- and touch-operated display systems. They provide users with access to screen content that would otherwise be impossible or hard to reach, e.g., because it is located behind a bezel or far away from the user. Drag-and-pop is an extension of traditional drag-and-drop. As the user starts dragging an icon towards some target icon, drag-and-pop responds by temporarily moving potential target icons towards the user’s current cursor location, thereby allowing the user to interact with these icons using comparably small hand movements. Drag-and-Pick extends the drag-and-pop interaction style such that it allows activating icons, e.g., to open folders or launch applications. We conducted a user study comparing drag-and-pop with traditional drag-and-drop on a 15’ (4.50m) wide interactive display wall. Participants where able to file icons up to 3.7 times faster when using the drag-and-pop interface.

Push-and-pop is a follow-up technique that combines the strengths of drag-and-pop with the push-and-throw technique, which allows it to create a more stable layout of target icons. Download the demo from Maxime Collomb's page.
