Talk of Google Glass was strangely absent from the company’s marathon, three-hour keynote speech Wednesday, but the company shared news that it’s working with major partners — including Facebook, Twitter and Tumblr — to offer more apps for the new gadget.

In a session for Glass developers, Google also released some information on future plans for the device, such as streaming video.

Along with the big social networks, the company’s other partners in app development for Glass include the note-taking service Evernote and news organizations such as CNN. The Facebook app will let users share posts from the headset, while the Twitter app will let users see messages in their streams and send Tweets and photos from the headset.

Having strong apps for Glass is key to the product’s success, as Google may have a hard time convincing the average person that its wearable technology is worth buying and that having this kind of Web access in your line of vision is far better than having to reach for it in your pocket.

Google’s Timothy Jordan, the senior developer advocate for Glass, said that the headset’s technology is meant to be “there when you need it and out of the way when you don’t.” For example, he said, concert attendees who record events on their smartphone often end up looking at their device’s screen instead of the stage. Glass, he said, solves this problem.

“By bringing technology closer, we can get it more out of the way,” Jordan said.

Google will be releasing a Glass Developers Kit to folks who want to build programs for the headset, the company said. Jordan didn’t say when when the kit would be ready, but he offered some tips for developers. For example, make sure that Glass users know the types of notifications they’ll be getting on the Glass screen, which hangs just outside the line of sight of the user’s right eye.
