No technology is totally new. Most amazing consumer devices are actually from some “grandpa” technology invented several decades ago, but just gets re-invented in miniaturization with modern fabrication process. From personal interest, I share technical slides like this, to introduce the context of the technology of sensing system that have been adopted in consumer product. Hope it helps and inspires those who are doing R&D in related fields. Note that all market/technical inference here are based on non-confidential information easily searchable on websites. ]]>

Magnetic tracking is one of miscellaneous motion capture methods, and maybe the oldest. However, its working principle is rarely introduced in detail perhaps due to its early adaptation resides in military and medical industry. Due to my interest in VR & animation MoCap, I’ve spent some time digging into the very depth of it and would like to share some non-confidential knowledge of it with you. In this slide, a short history of magnetic tracking will be visited, followed by its working principle and algorithm simulation. Hope you enjoy it. If you wanna discuss something in depth with me, please don’t hesitate to contact me via: dibao.wang@gmail.com ]]>

This slide is my observation of VRAR technology and market with my visiting in CES 2018. Although the VR market has been going up and down in past three years, market leaders (like Vive or so) are still pushing the product spec toward better experience (finer resolution and wireless), and start-up companies are focusing on innovative tracking solutions for whole-body and fingers. Hope this slide helps those who are interested in the VR tech development.]]>
