The first one is Google Goggles and is searching by picture. It lets you take pictures of books, landmarks and other things, and then gives you the informations it thinks your asking for.
The other one is Real Time Search. It lets you search a subject and then shows you the newest information on it, from twitter to serious news sites. It also takes you location into consideration, so the posts being shown is different from place to place.
Another cool feature that was announced was voice search in Chinese and Japanese. They also demonstrate an audio translate feature to android phones. They can all be seen in the presentation here.
