Did you like Mission Impossible and the heads up displays?  How about the Terminator’s eyeballs?  Well if you want a heads-up display to read off stats like altitude, speed and latitude and longitude the world got a whole lot cooler with the Zeal Trascend Goggles.  The Transcend is one of those high-end, early-adopter toys but is affordable to many folks at the intro price of $350.  Plus it is cool and incredibly useful.  Key technology includes; an accelerometer, air pressure sensor, thermometer and SKYTRAQ 65 GPS chip.  Rather than projecting the metrics on the lens, which might be difficult to read if you fog your goggles like me, it is displayed in the lower right part of the frame. The data is stored locally and can be extracted via mini-USB, and will give key stats such as maximum speed, vertical change, ability to map to Google maps etc. The goggles incorporate most the features of sport watches such as the Garmin 405.  Watch for this technology to be added to cycling and maybe average glasses soon and then the next generation including holographic optical switching technology.
