Applications to follow four Glass principles
Google has demonstrated some potential uses for its head-mounted display project at SXSW Interactive. Software, including versions of Gmail, Evernote, Path, and the New York Times, were shown off, explaining how Google Glass would interact and display the content using Google's Mirror API for the headwear.
The New York Times would be able to offer hourly updates to the Glass headset, according to The Verge, with the "look up" gesture providing photographs and headlines, and the text-to-speech facility reading out the content itself. Evernote allowed for photos to be shared through Skitch for future annotations, and Path showed how the user could view photographs shared with them, before selecting emoticons to apply to the image.
The Mirror API is being provided to developers in order to build similar experiences made specifically for Glass. Timeline cards can be filled with images, video, and HTML through the API, though Glass apps need to follow four principles: design for glass, don't get in the way, keep it timely, and avoid the unexpected.
Google is aiming to release a consumer version of Glass before the end of this year, and expects the final price to be under $1,500.
