LA tech start-up Daqri has updated the hardhat with Google Glass-like technology. The idea was profiled last fall in Builder magazine. Writer Kayla Devon noted:

The Smart Helmet offers the same protection of a hardhat, but looks more streamlined and includes a clear visor covering the top half of the wearer’s face. It uses an Android operating system and has a battery life of at least eight hours. Features include 360-degree navigation cameras, an industrial-grade inertial measurement unit, and a high resolution 3D depth camera. It also has the capability for HD video recording, photography, 3D mapping, and alphanumeric capture. All of this technology comes within the same dimensions and weight limit of a typical hard hat.
