Google Glass was at the SXSW Festival, and Google's senior developer Timothy Jordan showed off the device and a few of the apps that will available for the augmented reality eyewear.
Jordan was able to open up the New York Times app, which allowed him to see images and bylines for every new headline that scrolled onto the device. Glass could even read out the headlines to the user if they are so inclined. Evernote is an app that allows the user to share photos and other media, much like a email service. And Glass, being a Google product, of course supports a Gmail app. A picture of the sender pops up with a subject line, and the user can dictate to Glass a response to the email.
Glass apps function based off of "timeline cards." These are similar to the cards used for the Google Now app that runs on certain Android devices. the timeline cards use text, videos, images, or other groups of useful, expandable data that can be used for multiple timeline cards. This allows the Glass to give better predictions of what the user will want when using the device, much like Google Now uses the same data to try to prepare a search for users before they are done with their query.
Being that Google Glass is a unique device, Google has encouraged developers of the apps for the device to build specific apps for the device, rather than try and port their existing apps over to the Glass. This way the apps will be as unobtrusive and easy to use as possible for Glass. Glass will be available for customers eager to buy the fascinating eyewear by the end of the year, and should cost less than $1,500.
