On Wednesday, Google gave people a clearer picture of its secret initiative called Project Glass. The glasses are the company’s first venture into wearable computing.

The glasses are not yet for sale. Google will, however, be testing them in public.

In a post shared on Google Plus, employees in the company laboratory known as Google X, including Babak Parviz, Steve Lee and Sebastian Thrun, asked people for input about the prototype of Project Glass. Mr. Lee, a Google product manager and originally worked on Google mapping software Latitude, mobile maps and indoor maps, is responsible for the software component and the location-based aspects of the glasses.
