Privacy issues be damned. Microsoft thinks the problem with Google Glass is shorter temple arms. This was revealed in a patent granted to Microsoft this week.

Abstract: A HMD includes a pair of temple arms having spring steel that wraps around the head to provide long axis compression. The spring steel arms produce a compressive force along the long axis of the head that counters the gravitational force of a weight positioned at the forehead. The weight is supported by the long axis compression, rather than resting on the nose, ears or the top of the head. The front to back, long axis compressive force frees the head from all but the smallest amount of paraphernalia and allows for the weight to be worn in a way that is comfortable and non-intrusive. The spring steel temple arms are over bent inward well beyond the smallest size head and is used with a spine material that limits how far the temple arms can bend inward. An interface layer is also attached to provide comfort to the head.
