Google released an update to the Glass software codenamed XE9, the update is tremendous and adds a ton of search and other features. In short, it added video search results, news search results, sound search results, vignettes, transit cards, reminder cards, attractions nearby cards, nearby photo spots, search history for Glass, Google Apps support and remote control via MyGlass App.

Let's start with the feature Google "borrowed" from my How Do I Glass App. In short, it is the same thing but tightly integrated because Google has access to make it tight. You ask Google via Glass, "how to do X," instead of my verbiage, "how do I do X" and Google will give you back search results. If the search result is a video, it will let you play the video. My app searched YouTube and required a few more clicks.

Other search features include:
Sound Search
News search results
