Abstract There is a growing and sometimes critical need to ubiquitously process, visualize, and merge information with the world around us, in real‐time. This need has created a renewed interest in see‐ through (as opposed to look‐at) augmented mobile viewing systems that are compact, low cost, and convenient, with resolution that approaches that of the human visual system extending into the peripheral field of view. We will review key technology paths that build on historical highlights and discuss some market barriers to the emergence of eyewear format head‐ worn displays (HWDs). Finally, we will focus on freeform approaches and feature emerging solutions in freeform combiners that build on a novel description of freeform surfaces and provide a key competitive advantage in the ability to separate the see‐ through scene and the user by a seamless thin plastic window.
