Varjo High-Resolution HMDs
Headsets by the Finish start-up Varjo recently have had a profound impact on the market of business-to-business virtual reality devices. Varjo’s advanced display technology allows viewing immersive environments with uniquely high resolution. It makes the company’s HMDs a great choice for professional design and industrial applications.
We have been working with Varjo for a few months in order to adapt our LPVR driver to work with their headsets. As a result we have recently released a first version of the driver and are ready to deploy it to customers.
LPVR Tracking Technology
Valve Lighthouse is the default tracking technology built into Varjo headsets. This system, in spite of being very suitable for games and single user applications, is limited in its tracking volume and accuracy (mainly reproducibility). In order to allow multi user, large space applications (location-based VR) an alternate tracking system is needed.
With LPVR-CAD for Varjo we allow the combination of Varjo headsets with our tracking technology, based on marker-based inside-out tracking, feature-based inside-out tracking or outside-in tracking such as Advanced Realitime Tracking (ART).
Besides static tracking solutions we also offer support for our LPVR-DUO in-car tracking system.

Location-based Virtual Reality for Automotive Design
Figure 1 – Using LPVR-CAD large room-scale tracking, 3D design content is visualized on VIVE Pro HMDs
In cooperation with Korean automotive design solutions provider AP-Solutions, we created a large location based virtual reality installation at the Hyundai research and development center close to Seoul, Korea. The system is used to showcase, amend and modify prototype and production-ready automobile designs (Figure 1).
LPVR Large Room Scale Tracking Engine
Figure 2 – Each VIVE Pro HMD is equipped with optical tracking markers and an LPMS-CU2 IMU. The IMUs are covered with black tape to avoid reflections of infrared light.
The system uses optical tracking together with LP-Research’s LPVR solution to track up to 20 users wearing Vive Pro Head-mounted Displays (HMD). Each user carries a VIVE hand controller for a total of 40 tracked objects in a space close to 400sqm.
Responsiveness is achieved by using LPVR (Figure 2) to combine LPMS IMU data and a software package to achieve optimum performance. The optical system uses 36 infrared cameras to track the 160 markers attached to the HMDs and hand controllers. The position and orientation data of each user’s HMD is combined using LP-Research’s algorithm.
The content of the virtual space is rendered using a CAD software package running on backpack PCs worn by each of the 20 users. The PCs communicate and coordinate via a central server.

Human Motion Capture
Human motion capture is a term commonly known from the world of movie production: Gollum in The Lord of the Rings lurking and smiling at his shiny ring in a weirdly human-like manner or the beautifully alien creatures of Avatar floating through a fantastic landscape.
Although transferring human body movements to a movie character is an established method, it might be surprising to some that human motion capture has a range of applications in a areas beyond the world of film production.
Motion Capture can improve human life by boosting a person’s work efficiency, support injury recovery and help preventing excessive strain on the human body under rough working conditions. The medical and manufacturing industries are just two of many fields where motion capture helps to optimizing human movements.
IMU-Based Technology for Refining Human Motion
One of the main topics of LP-RESEARCH for the application of its advanced sensor technology is to provide means for quantitatively refining human motion and make them faster, safer and more efficient.
LP-RESEARCH’s chief scientist Tobias Schlüter is writing software that uses motion sensor data to measure the movements of a person. Small sensors attached to the subject’s limbs track body motion and based on the acquired information, adjustments can be made to the subject’s movements.
This can result in improved speed safety and efficiency for a specific activity.
Worker Safety & Well-Being First in Industrial Production
Using this technology a patient trying to recover from a severe injury might find a faster way back to normal life. A runner working to improve his running style might gather useful information to optimize his training strategy.
A central topic in industrial manufacturing is the improvement of production efficiency: human workers performing repetitive tasks face problems of fatigue and physical conditions like back pain. Human motion capture and the corresponding analysis methods help to correct sub-optimal movements to help the work fatigue less, stay healthy and at the same time become more efficient.
With applications in sports, medical treatment, industrial production and more: Sensor technology from Tokyo – welcome to LP-RESEARCH.
