The multinational corporation are reportedly working on glasses that look like regular ones but they connect wirelessly to phones using Bluetooth, for example, and could be voice controlled.
The patent reads: "Single-touch immersion control of head-mounted display (HMD) systems is described. One method outputs video from an electronic device to a HMD system that includes a display layer and a variable-transparency layer.
"The electronic device controls the variable-transparency layer to operate in a first state in which the variable-transparency layer is transparent and to operate in a second state in which the variable-transparency layer is opaque. The electronic device switches between the second state and the first state in response to a single-touch event detected by the electronic device."
It comes after Google Glass revealed they had returned to the mark with a special Enterprise Edition.
Jay Kothari, project lead, shared: "Glass is a very small, lightweight wearable computer with a transparent display that brings information into your line of sight. In a work setting, you can clip it onto glasses or industry frames like safety goggles so you don't have to switch focus between what you're doing with your hands and the content you need to see to do your job.
"Workers in many fields, like manufacturing, logistics, field services, and healthcare find it useful to consult a wearable device for information and other resources while their hands are busy.
"That's why we've spent the last two years working closely with a network of more than 30 expert partners to build customized software and business solutions for Glass for people in these fields. We've also made improvements to the design and hardware so that it's lightweight and comfortable for long term wear. We've increased the power and battery life too."
