Yesterday Apple unveiled the iPad and at first blush it just looks like a big iPod Touch; but after combing through the keynote, I found a few new or extended interactions that are pretty interesting. Granted, some of these interactions may be extended to the iPhone and iPod Touch, but many are probably unique to the larger device format.
Spread/Pinch to expand/close piles of photos in iPhoto
In the screen cap below, piles of photos can be expanded or closed by using a pinching motion. This could be applied to virtually any document type.
Phil Schiller demonstrated a way to move multiple slides at once by collecting them into bundles. Start by selecting a single slide to move. While holding this slide, tap other slides you want to move. These additional slides get bundled together and you move the bundle to the desired position. It’s a little tough to see it in the screenshot below so check out the keynote video at about 01:01:00 to see it in action.
A similar bundle or “pile” treatment is used in Mail. In this example, the user is selecting four messages. As each message is selected, it gets added to the pile. The user is then able to mass delete the pile of messages.
This example is from Pages. Press and hold your finger in the scrollbar area and you are presented with a viewer. As you slide your finger down the screen, you can see a small preview of the page you will be taken to once you release your finger.
We’ve already seen this on the iPhone with apps like facebook and eTrade, but it’s nice to see it applied to productivity apps. In the screenshot below, Phil scrolls through a set of tabs in the Numbers application.
Another feature we’ve already seen in use on the iPhone is the contextual keyboard. You can see how this is logically extended for Numbers, providing a numeric keypad for number columns with access to formula via a control panel.
More gestures in the SDK?
Of course, there’s plenty of innovation yet to come from third party developers and the larger screen allows for the use of more fingers. In the example below, EA is using a three finger gesture to unlock a door. It will be interesting to see if developers have the flexibility to define a lot of new gestures using different combinations of fingers.
Update: Luke Wroblewski and I collaborated to enhance this posting with video (thanks, Luke) and a few more interactions. Check out the post.
