These sunglasses will bring a virtual chef to your kitchen
Steffen Henssler knows what it means to cook on TV. Cameras, headlights, stressed recording conductors. The TV chef is used to all this. But this time everything was different. This time, he had to squeeze into a tight full-body suit covered in sensors. A frame fixed a smartphone camera just a few centimeters in front of his face.
Because Henssler should not only be on the screen. He should go into mixed reality, into a mixed reality. Pictured in augmented reality glasses (AR). For this, Henssler had to get a virtual clone – and be scanned virtually in its entirety.
With Henssler, the mobile communications group Vodafone is launching its new platform Giga AR, on which applications will be found in the future that complement our reality with virtual representations. The start is the cooking app with Henssler and recipes from Kitchen Stories.
If you want to see the chef at work three-dimensionally from a distance, you need AR glasses. Vodafone has teamed up with the Chinese start-up Nreal to bring the first AR glasses for private users to Germany. Deutsche Telekom is also preparing a corresponding offer together with Nreal. WELT has already been able to test the glasses.
While private users have been able to choose between different virtual reality glasses (VR) for a long time, augmented reality glasses have so far only been reserved for professional users. VR glasses are heavy and large glasses that put their wearers in games and environments where they are completely sealed off from the actual reality around them.
VR glasses are available from Oculus, Sony, HTC (Vive) and HP, for example. In contrast, AR glasses are transparent. Users see their environment while virtual objects are displayed and refer to the real environment.
For example, instructions can be displayed to technical employees who are currently repairing a machine. Such glasses as the Hololens from Microsoft or the Magic Leap cost 2000 to 3000 euros. Although they are more discreet than VR glasses, they still have massive frames.
The Nreal Light has nothing to do with these professional glasses. Although the mobile operators have not yet published their prices, but according to information from WELT, the glasses will cost less than 700 euros.
Vodafone and Telekom are preparing packages together with a smartphone and are likely to hand over the devices at a discount in connection with a mobile phone contract. So Vodafone wants to sell the glasses together with the smartphone Oppo Find X3 Pro in the more expensive mobile phone tariffs at the start for one euro.
The market for VR and AR glasses is still small. Experts expect a breakthrough only when they reach the size of ordinary glasses. The Nreal Light is the first glasses of this size to actually approach. It weighs only 106 grams, although in addition to two microphones and speakers, it has cameras and some sensors built in to be able to detect the position of the glasses wearer in space. On request, corrective lenses can also be inserted.
The Nreal Light is connected to an Android smartphone via a cable. From there, it receives the power on the one hand, and the computing power on the other, in order to be able to represent virtual objects in three dimensions. With iPhones, the glasses are not compatible. Apple is reportedly working on its own AR glasses.
The darker the environment, the better the image
In the test, the Nreal Light was much more comfortable to wear than VR glasses over a longer period of time. When the glasses are connected to the smartphone, Nreal’s user interface Nebula automatically starts with an overview of the installed apps.
The choice is currently not too large. Although the Google applications Chrome, Maps, Photos and YouTube are present. But they, like Instagram, Facebook and Twitter, are presented only as two-dimensional displays.
The interface is operated via the smartphone, which then functions as a laser pointer. If the pointer is directed to an app icon, the application can be opened with a tap on the display. The applications can then be freely placed in the room and enlarged or reduced in size.
Although this has nothing to do with augmented reality, it is already impressive. Because the glasses have a Full HD resolution on every page and displays both the text in the browser and movies on YouTube accordingly sharp, bright and with strong colors. At the same time, however, you can also see your own surroundings as if you were looking through sunglasses. The darker the environment, the better the appearance in the glasses.
However, the field of view of the displays is limited to 52 degrees. This is not much and leads to the fact that one should not wind displays too much, because then they are cut off at the edges. With the glasses, you can create the impression of watching videos on a TV with a diagonal of two meters – and that’s fun.
Since the glasses get the power from the smartphone, the battery level drops quickly there. But for a two-hour film it is enough. After a few minutes, the glasses also get warm, but not nearly as uncomfortable as you know from some VR glasses. In the test, the glasses switched off automatically when the battery level had dropped to 30 percent.
With the Nreal, even three apps can be opened at the same time and distributed accordingly in the room. With its sensors and cameras, the glasses remember the location of the displays in the room, so that they remain in their place, even if you leave the room and come back.
In the glasses there is also a projection mode, in which the smartphone applications are simply mirrored. This allows you to use apps that have not been specially adapted for the glasses, for example Netflix or Amazon Prime Video.
A few apps in Nebula view are labeled “MR”, which stands for Mixed Reality. This does not always have to be meant that way, but at least it becomes three-dimensional there. Thus, in the application Spatial you can meet as an avatar with other users in virtual rooms and work on joint projects. The application is also available for other AR and VR glasses.
Deutsche Telekom has shown an application in the past where users can look at a dragon cave and walk around it. Even a flying dragon appears in the scene. The Tagesschau 2025, which was originally designed for tablets, has also been adapted for the Nreal. There, a news anchor appears in 3D as a demo.
Among the MR apps, of course, is the Giga AR from Vodafone. In fact, the cooking application contained in it is suitable for use in the kitchen, because it can also be controlled with the view on request, so that you do not have to touch the smartphone at all. If the view lingers a little longer on a button, it is pressed. For example, the cooking video can be paused.
It gets really interesting when star chef Henssler suddenly jumps out of the video, floats in front of you in three dimensions and gives additional tips. Moving around him, he even follows you with his gaze and turns his head – a little magical moment.
But to make augmented reality a mass market, it needs even more of it. As our test shows, the Nreal brings the technical equipment for this. Now it only needs the applications.
