“HEAD TRACKING BASED GESTURE CONTROL TECHNIQUES FOR HEAD MOUNTED DISPLAYS” – Patent application 20150138074, filed November 13, 2014.
Head gestures for dialogue box interaction:
This review is by no means exhaustive but does demonstrate the comprehensive nature of Kopin’s development in the area of head worn wearable user interface elements and systems.
Enterprise head worn devices with display pods will require UI elements that can be easily integrated with existing applications and operating systems in a user friendly manner to support worker safety and reduced training requirements. What you see assembled here is just that: wearables UI middleware known as the Golden-i OS which sits on top of Windows or Android operating systems to provide a complete hands-free UI layer for head worn devices.

User Interface Concepts For AR Head Worn Wearable Devices
Head worn devices will re-define how we access and manage information in the post-PC wearables era. Initially, I expect head worn wearables to achieve wide adoption in the enterprise and first responder markets. The list of advantages that access to hands-free work related information is vast. At the top of this list is the one advantage every industry values above all else: safety. At the following location, you will find a description of the head worn wearables display architecture called Video See-Through Augmented Reality that I believe will dominate enterprise adoption starting in 2017.
However, the head worn form factor will require a very different set of User Interface elements than we are used to using with PCs, laptops, or tablets. The very advantage a head worn device provides to enable safer work nullifies traditional mouse and keyboard input methods: head worn wearable devices must be hands-free. With that in mind, lets explore some leading UI concepts Kopin has developed as part of their Golden-i HMD platform. Below is a graphical representation of Golden-i from granted patent D714,786S which I have marked up to highlight design advantages.
Here are full color renderings of the Golden-i 3.8M.
So now that we have established the basic form factor of the Golden-i Video See-Through AR device, lets review how a user would interact with such a device using publicly available intellectual property Kopin has developed accessible via patent filings.
