Electronic enthusiasts eight o'clock early: VR head display allows us to get a three-dimensional visual experience in the virtual world, but people have five senses, so the light is definitely not enough. To make people find a position in a non-real world, touch is also very important, especially the interaction between the hand and the world. This is one of the foundations for players to find their own existence. To achieve this, we now rely on handheld controllers such as PlayStaTIon MOVE and Oculus Touch. They can effectively reduce some sense of misplacement, but still not realistic enough. The technology used by VR Touch is likely to eliminate these controllers in the past.
In fact, the technical principle of VR Touch is not complicated, it is essentially a small tactile feedback motor. You install these motors on your fingertips, and the subtle and precise vibrations simulate the touch in the virtual world. For example, pressing a virtual button, the kind of pushback that the motor brings, gives you the illusion of pressing down.
You may think that these small vendors have good ideas, but they will not be popular after all, but in fact VR Touch developer Go Touch VR has cooperated with HTC to make their products compatible with HTC Vive's Lighthouse positioning base station. And even without a base station, players can track the movements on their fingers by installing a Leap MoTIon sensor on the front of the VR head.
It is worth mentioning that the Go Touch VR is very detailed. The VR Touch itself is equipped with a gyroscope. If the sensor temporarily “cannot see†them, they can also be adjusted by the gyroscope for a short time.
The tester reported that the VR Touch system is simple but very effective. Nintendo's Switch has told us through HD vibration technology that vibrations do a good job to simulate a true touch to a considerable extent. The most interesting thing is that when the VR Touch's motor vibrates and tells you what you are touching, even if there is nothing in the real world, the brain will still have the illusion that your fingers can't move forward involuntarily. So, you don't need to worry about the feeling of disobedience that the hand can still pass through the virtual object despite the feeling on the hand.
Toia
In fact, Toia and VR Touch are a class of products, but they go in different directions. VR Touch wants to make the tactile feedback experience more affordable, while Toia is the opposite. Developers desperately want to restore the perfect tactile feel.
Toia is really daunting compared to the seemingly small and fun VR Touch. Its body is the same size as an old typewriter, with a device that is difficult to describe its shape, and the device is followed by a motor that is connected to the body by a robot arm. At present, Toia only supports up to two fingers, and the official said that the future finished product will support a more complete hand experience.
Because Toia's design is really not good, the process of putting your fingers in the device is also very difficult. However, once you are ready to start the experience in the VR world, you will have a completely different feeling, as if you are really touching the real object.
If VR Touch just uses motor vibration to make your brain illusory, then Toia can really make you touch something. When you touch something in the virtual world, the motor will push the actual hard object back. With such a physical system, whether it's a finger on something or picking up something to feel the weight, Toia will give you a near-real feedback.
However, because Toia's entire system is too cumbersome and complicated, the development team does not intend to push it to civilian use, and it is aimed at the professional field, for example, let the medical practitioners use VR to perform some operations such as surgery and injection.
However, the Toia system has its own drawbacks compared to VR Touch. Its design means that your hand activities are very limited, such as not being able to flip, not being able to move lightly. In addition, the motors currently used by the development team are not strong enough to allow some objects that appear to be metal or wood to have a rubbery feel. The latter can be solved through technical improvements, and the former is how the manufacturer is going to make it a universal system.
Shogun
If you think that what you said before is a bit too "small" and not revolutionary, then Shogun may be more interesting to you.
If you have a little understanding of the motion capture techniques in movies and games, you will feel that the Shogun system is really familiar. Also wearing a tight suit, you also need to install a lot of silver ball sensors around your body. But in movie games, it's just to make virtual characters show realistic and natural movements. In the VR experience, the Shogun system can make your avatars more flexible and vivid.
One of the hard-to-solve problems with VR games is that you are a real person in the virtual world, but the actions you can do are still very limited. If it is a VR online game, then your appearance is still very blunt in the eyes of others, and it is very illegal. Assuming that the Shogun system can be applied, even if the character is using an avatar, the action can still restore his or her own thoughts. I have to say that this is indeed a new experience.
Although Shogun is very interesting, it still has a lot of limitations. For example, even if it can achieve full-body tracking, it is too demanding for the site to achieve a wide range of movements. Unless you're from Shogun to Head-Up, content integration and self-positioning can be achieved with an entire system. To develop this technology, this may not be a problem that can be solved by a generation.
However, developers hope to solve it a little bit. At present, Shogun can only wear special tights, and manufacturer Vicon Software hopes to improve the technology so that the sensors can be installed on ordinary clothes.
