Amazing technology aside, this is a pretty disappointing API release from a developer standpoint. Basically no access to Glass's amazing hardware, nor any way to receive user input other than a swipe/tap on the side? I'm really hoping it gets more comprehensive.
The Glass will surely be hacked six ways to Sunday but I doubt the official API will go much deeper than it already is.
The still-disappointing Plus API pretty much tipped Google's hand when it comes to how flexible they want to be on providing APIs for future products and on top of that there are some pretty substantial privacy issues with giving developers low-level access to the vast amount of personal data Glass will constantly be collecting. I'm already worried enough about Google having that data that I'm sitting out Glass for the foreseeable future (despite the fact that I suspect it will be useful for a lot things), but if random third parties could access that data at a low-level I'd be even more worried.
I'm willing to bet that they'll have some android integration announcements at I/O. The Motorola phones are suppose to have touch controls on the back, which would be a pretty convenient way to interact with glass.
Actually from what I see the only way to receive user input is via user selection of menu options. There don't appear to be any callbacks from swipes or taps on the touchpad.
