I just watched Google Glass developer advocate Timothy Jordan's 50 minute long presentation from SXSW, where he publicly presented the Google Glass Project, some interesting use-cases and a first look at the Mirror API.

The whole platform feels sleek, elegant and simple. The API is similarly so, where the interaction and information transactions are small, timely and impactful snippets that augment what you are doing right now and otherwise, get the hell out of the way.

Design for Glass - The Glass design is unique and fundamentally different than existing mobile platforms. It's important to build and test specifically for Glass to create a great service.
Don't get in the way - Services should be there when you want them and out of the way when you don't. They should never take precedence over what else the user may be doing.
Keep it timely - Glass is most effective when in-the-moment and up-to-date. User requests should be handled immediately and information should always be fresh.
Avoid the unexpected - Giving users unexpected and unpleasant functionality is bad on any platform, but particularly bad on Glass given how close it is to the user's senses.

I've been working on a fascinating project with Nutribu, a startup looking to transform how we interact with the complex and boring world of nutrition into a fun, social and competitive experience.

Google Glass could be the answer to how we may capture real-time transactions, like eating a meal, in an unobtrusive or overly clunky way - a problem which currently exists with web and mobile nutrition diaries and calorie counters.

Instead, Glass potentially offers all sorts of mechanics to make nutrition, eating consciously and with access to relevant information about our consumption a fun, data-driven and socially interactive experience.

It also gets me thinking about we access our personal information repositories, with services like my very own Braindu, so that our data is available to us in an actionable, real-time mechanic. I'm very excited to try out the API and build Mirror API-based services.

You can see my Braindu chart on the subject of Google Glass here with links, videos, images and notes that I expect will grow over time.
