"OK Glass:" Translate this
You can see in this example that swiping through the menu can take a few seconds. It is often easier to simply tap the arm of Google Glass and say, "OK Glass…" and then your query.
One of the available apps, called "glassware," is World Lens, which integrates well with the wearable technology, allowing users to translate text in the real world on the fly.
"OK Glass… translate" brings up the camera, which focuses on translatable text. Depending on your language settings, it will in your prism-like display replace words in your native tongue. It has yet to be refined as it is currently more of a concept at this stage, but it works with enough accuracy to generally get the idea of what it's trying to say.
