HaritoraX is a full-body tracking device for waist and leg motion that is compatible with SteamVR. It runs for 10 hours on a built-in battery and can be combined with wireless VR goggles such as Oculus Quest 2 for wireless full-body motion tracking.
Having your hands full with VR goggles and a controller you can't even get your avatar to sit on the ground or in a chair. You cannot express cuteness by sitting like a kawaii girl, nor can you strike a pose with your legs crossed.
When you dive into VR social networking sites you see a lot of cute and cool avatars doing all kinds of movements. With HaritoraX, you get to express a wide range of movement.
Batteries can last up to a few days and no need to plug in numerous USB cables to recharge. Each module is connected via cables so HaritoraX has only one charging port, and it is possible to experience VR for even longer than 10 hours while powered by a mobile battery.
VR metaverse extreme users have already adopted this approach for long hours of use (no kidding).
It is important for a full-body tracking device to be able to hold itself fast to the body.
The HaritoraX suit covers a wide range of body sizes, from women's SS size to men's XL2 size.It can also be used by those who have a size S top but XL bottoms.
Our tracking method is not based on external sensors such as a camera, but on a geomagnetic and acceleration sensor (9-axis IMU), which enables tracking in any stance.
It can be mounted either to the side of the legs for sitting upright or sitting cross-legged, or to the front of the legs for less resistance when lying down.
In addition to VRChat, we have confirmed that it works with Chillout VR, NeosVR.
It works not only with these apps but also with a variety of SteamVR compatible apps that support full-body tracking.
The accuracy of a full tracking device that uses a 9-axis IMU is highly dependent on the quality of the posture estimation application for Windows. Even with a similar sensor, the avatar's movements are completely different depending on the app's design.
Based on the first generation Haritora developed by “izm” and volunteers, HaritoraX is the next generation of Haritora developed in collaboration with Shiftall.
The “Haritora Configurator”, an acclaimed posture estimation application that has been continuously improved with the original model, performs advanced posture estimation. In addition, the on-board "Quick Calibration" function enables screen-less posture correction from within the VR space, with no loss of the fully immersive experience.
HaritoraX plans to expand its functions after its release. Range sensors for additional functions are built into the shin Unit for more accurate foot positioning on the floor. The latest firmware can track ankle movement by using the range sensors (Currently, the function released under open beta testing)
It will have an additional port that can be expanded to 6 or more tracking points by purchasing an additional sub-unit separately. After the product launch, we are planning to keep improving the performance using these extended functions and the software.
In addition to the 3 tracking points on the VR headset (head) and controllers (right and left hands), HaritoraX adds 5 tracking points* for a total of 8 tracking points.
In addition, 2 additional tracking points will be achieved with the newly announced HaritoraX elbow tracking expansion set (right and left elbows) and 1 additional tracking point with the HaritoraX hip tracking expansion set (abdomen), for a total of 11 tracking points.
11-point tracking can reproduce the motions of the human body in the real world in its entirety in the VR metaverse and is considered an optimal environment for users who enjoy physical motions such as dancing in the VR metaverse.
* With the release of the expansion set for elbow tracking, the Haritora Configurator will be updated to increase the number of tracking points in the VR Metaverse applications such as VRChat from 3 to 5 when used with HaritoraX alone.
The avatar's elbow motions are reproduced by estimating the position of the elbow joints from the position of the palms, even if only a VR headset and 2 hand controllers are used.
In reality, if you rotate your wrist or move your elbow while holding your wrist steady with the VR headset and controllers, their motions don't sync well with avatars in the VR Metaverse.
The HaritoraX elbow tracking extension set allows for more accurate elbow motion.
HaritoraX had previously used 5 IMUs to generate 3 tracking points in the VR Metaverse, but due to the poor usability of wearing 6 IMUs on the body and the advanced posture estimation and correction capabilities of the Haritora Configurator, 5 IMUs were sufficient. The system was designed to use 5 IMUs, which would have been sufficient.
However, the use of 6 IMUs enables accurate tracking, even in special postures where the avatar would move differently from reality with 5IMUs.
In addition, the phenomenon commonly referred to as "feet sliding" in which the avatar's feet slide on the floor, is greatly reduced.
