If you think that all VR experiences need to be achieved through a VR glasses, it is a big mistake. Scale-1 Portal from France's VR company has made such a projector SCALee, which can have a strong sense of immersion without VR glasses. Zhizhi recently contacted Emmanuel Icart, the co-founder of Scale-1 Portal, and talked about the story behind SCALee.
Why not do the projections and do the projections?
Emmanuel Icart and two other co-founders Julien Baessens and Olivier Legrand met in 2009 when they worked at a simulation test center at a French car company, often dealing with VR head-mounted devices and virtual reality simulators. But they agreed that the VR head was too high-profile and complicated, so in 2014 a prototype set of projectors was made.
Emmanuel Icart said that the product is called the name SCALee. First, "Scale" is the name of the company. After that, an "e" is added. The two "ee" are like the heads of two users. Indeed, at the CES show earlier this year, their show video was a family watching the same video delivered by SCALee on the couch.
How does projection achieve immersion and interaction?
Unlike normal VR video, SCALee does not require VR glasses to watch. SCALee includes a powerful PC for the Win10 system, which combines projection and somatosensory detection to project a 1:1 3D video onto the wall and capture the user's movements with a somatosensory detector. At the same time, it is equipped with four curtains. When used, the four curtains are put up to form a square space with the floor. The projector will put a continuous picture on each side to form a 360-degree virtual reality space. According to Emmanuel Icart, the immersion of this device is very good, the player standing in this space, wearing a 3D glasses can see the three-dimensional picture, and the whole body is immersed in it.
The innovation of SCALee is that this is the first complete projection-based solution. SCALee uses projection instead of the VR head-mounted display to create a sense of immersion with a closed screen. The main difference between SCALee and 3D movies is that the projected image is interactive. Users can devote themselves to the virtual world: actions such as opening, shooting, and jumping can be achieved in the virtual world.
In fact, seeing this product, it is easy to think that it is an upgraded version of the somatosensory game machine. After all, the somatosensory game machine is a product that appeared a long time ago. It also uses the camera to capture the human body movements. The game machine then follows the corresponding reaction. For example, in many game halls, there are dance machines that require players to do the same actions with the people on the screen, and they can be scored by the camera.
When playing a dance machine in the game hall, many people may have the feeling of motion recognition. The VR head display is more accurate in recognizing the action, and the head can be seen to change with the head as soon as the head moves. The space projected by SCALee is also very large. For the accuracy of motion recognition, we asked Emmanuel Icart. He said that SCALee can recognize the accuracy of 1cm, which is already accurate for whole body recognition.
How to disassemble and work hard to play at home?
The large footprint also means that the device is difficult to use at home, and it takes a few hours for the curtain to be removed and installed. According to Emmanuel Icart, SCALee is currently used primarily in mobile and commercial applications such as real estate and education. Although the game is also played, for the game, it is generally sufficient to use only two projection surfaces of the wall and the floor.
If a consumer wants to buy a home to play games or watch videos, it is okay to use a curtain. As long as there is a clean wall and floor 3 meters wide, you can play. But currently only two adaptation games are available. One is a game that avoids obstacles. Players need to bend over and jump to avoid obstacles such as pipes and balls on the front screen; another is similar to cool running. The left and right movement of the body to control the direction, but also raise your hand to open the fire to remove the obstacles ahead.
Regarding the content source, Emmanuel Icart explained that they will monitor every available content platform and gradually open up third-party developer platforms. They care about the details of each content to ensure the best user experience. In addition to the business and education sectors, the next step is to make a difference in the health platform.
To sell $5,000 to land in China recently
3D projection and somatosensory detection are all existing technologies, and according to Emmanuel Icart, this form of virtual reality is not new, and there have been more than a decade of research and development history before the launch of consumer products. This form seems to face fewer problems than the technical thresholds of various VR heads that have only been developed in recent years.
Emmanuel Icart said that this is not the case. The biggest challenge at present is the need to re-optimize the production chain and reduce assembly costs. The entire SCALee is priced at $5,000, which is a bit more expensive than a few hundred dollars. Only a few companies can afford it. Their next goal is to make the product more practical and more Strong, so that ordinary consumers can afford it. There is still a long way to go before it can be truly popularized.
The other party also disclosed the financing and mass production situation. At present, the professional users have already opened their sales channels and will sell them in China in the future. The distributors currently contacting China will soon enter the Chinese market.
to sum up
There are many VR products on the market, most of which are head-mounted, Oculus, HTC Vive, PS VR basically occupy half of the country. The technology used by SCALee has been around for a long time, but the combination of VR experience is the first.
The advantage of SCALee is that it does not require a display device to create a good immersion, and this immersion is full body. In the home use scene, several people can watch the video together. The 1:1 ratio is better and more realistic, and the recognition of the action is also very accurate. The shortcoming is that the price is very high, the construction of the curtain is large, and the floor space is also large, which is very inconvenient for people who use the family. At present, it is mainly used in the service industry, such as real estate, education and other fields have good development prospects, but the main use of the family is mainly video, less game resources. The head display is a panoramic picture created with vision, which is more suitable for the game experience than SCALee.
Different forms naturally have different points of focus. In my opinion, the product form is different, and the field of application is naturally different. The heads such as SCALee and Oculus are not able to compete in one field. Nowadays, there are more and more VR product forms, and more fields will start to apply VR technology in the future. Competition or cooperation, no matter which form, it is important to grasp the characteristics of its own to find the right cut, consider the user experience, and constantly increase the content, in order to truly occupy the market.
