Motion tracking continues to gain popularity due to its versatility and growing commercial appeal. From the entertainment industry to the automotive industry, motion tracking is opening new ways to interact with data and has become an asset many companies can’t afford to ignore.
Motion tracking bridges the gap between user and technology — making complex digital tasks as easy as simple human movement. But how does motion tracking work? And, which workflows benefit the most from the ever-evolving technology?
How does motion tracking work?
There are several methods of tracking motion. The most popular of which is optical tracking. Optical systems acquire data by capturing imagery of markers placed on a subject or any objects that will be tracked. Markers are small objects that typically reflect (passive) or transmit (active) infrared or visible light that is captured by multiple cameras. The data from multiple cameras can be used to compute the 3D position of the markers and provide the subject or object’s position and orientation in 3D space.
There are several other motion tracking methods including inertial, magnetic, acoustical, and additional optical techniques. Picking the right tracking system relies on many factors including the environment you will be tracking in, workflow, and cost.
Professional applications for motion tracking
The most well-known application for this technology is motion capture. For the purposes of TV, films, and video games, tracking systems record human models and then transpose movement onto computer-generated images. This is a popular method of capturing CGI footage and its utility has increased over the years as technology continues to become more sophisticated.
Manufacturing companies have adopted tracking technology for two primary reasons:
Enable real-time motion tracking — Real-time motion tracking improves day-to-day productivity by enabling new ways to interact with visual data. Many companies use tracking technology to navigate user interfaces, manipulate objects on screen, collaborate in video calls, and more.
Improve virtual reality interactivity — Motion tracking has brought on a key advancement for VR: improved interactivity within 3D environments. Engineers and designers use motion tracking to interact with models with greater precision. This could include head tracking to manipulate perspective within a virtual car or plane, manipulation of a mock steering wheel to replicate driver experience, and much more.
There is a lot of variety when it comes to motion tracking hardware, and determining the right option comes down to your organization’s needs.
In some cases, motion tracking can be easily integrated with existing visualization technology such as a PowerWall. This allows for simple actions such as menu navigation.
In instances which require more interactivity, motion tracking can be paired with virtual reality hardware. A virtual Reality (VR) head mounted display (HMD) can be augmented with motion tracking technology to allow simple interactive actions. For an even more immersive format, your organization might benefit from a CAVE system — a multi-sided environment which projects high-resolution content on all sides.
There are several applications for motion tracking and virtual reality, including: reviewing vehicle ergonomics with greater precision, including multiple users within a virtual environment, and lowering risk for training new employees.
With so many motion tracking options on the market, and countless permutations of hardware, it’s easy to become overwhelmed.
