The Animal Eye Simulator

Experience the stable through the eyes of a cow, horse or pig

Welcome to the Animal Eye Simulator. With this world first, we visualize how cows, horses and pigs probably perceive their environment. To do this, images taken by two cameras are projected onto video glasses and processed with a variety of filters, so that the wearer of the glasses can understand the animals' visual perception:

Despite a large field of vision of more than 300º, the animals have tunnel vision because the edges of the visual field are blurred and fuzzy.
Compared to a human, they only have about 30 percent vision in the lateral field of vision.
The animals have a different color perception than humans; they cannot see red (dichromacy).
Contrasts are perceived more extremely.
Cows and horses adapt to changing light conditions more slowly than humans.
Cows and pigs are much worse at judging distances than humans.

If you have experienced how a cow, horse or pig perceives its environment, you can understand the animals better and deal with them better. By using the simulator, people's perception of the animals can be changed, and barn systems can be optimally geared to animal welfare. If the farmer no longer uses force to drive a stubborn cow in the milking parlor, but instead looks for the problem with his eyes and ears, both the cow and the dairy farmer benefit from the animal glasses technology. Riders who have already entered a horse trailer with our system can better understand the needs of the horses when loading.

Buying such a system does not make sense for every user. That is why you have the option of booking a visit from us with the glasses at your company.

We are very successful with our seminars on farms, horse farms and abattoirs in order to convey the perception of animals to people, thereby strengthening animal welfare and making it easier to handle animals. The reactions to our visits and lectures are consistently positive, please feel free to contact us. You will find our contact details below.

The Simulator

The simulator is operated with a specially developed 360º camera. Otherwise, the system consists of commercially available components: Virtual reality glasses and an upper mid-range laptop. The software we developed controls the components and displays the image captured by the special camera on the VR glasses and the laptop screen. Various settings can be changed during runtime, for example the animal's color vision, which is different from that of humans, can be switched on and off. We supply the camera and software required for operation, the rest of the hardware must be purchased by the customer.

VR glasses

In principle, any pair of glasses can be used that can be configured as a second monitor of the computer system without additional drivers, e.g. via an HDMI connection. These glasses are also known as goggles and are often used in conjunction with drones. The software was developed with VR goggles from DJI, but these are no longer in production. We now recommend the use of the Skyzone SKY04X, the camera is mounted on a construction site helmet for which we manufacture special attachments. To a certain extent, the Skyzone allows use by several users with different visual acuity and eye distances without having to replace the lenses. It also has a ventilator that ensures a clear view at all times. These features are very important if groups are to work with the simulator.

Hardware requirements

The system was developed on HP notebooks from the ZBook series with an i7 processor and NVidia graphics card. The systems have an SSD and are well suited for use in the stable or on the pasture. If you want to use a different computer, it should meet the following requirements:

At least six processor cores, preferably eight.
Clock frequency at least 2.5 GHz.
At least 8GB RAM, preferably 16GB RAM.
NVIDIA graphics card with CUDA support.
Two USB 3.0 interfaces for the cameras. Each interface must have at least 650 mA available to power the cameras.
HDMI video output for connecting the video glasses.
The HDMI video output must be configurable as a second video output, not as a mirror of the screen. You see different outputs on the two screens, an extension of the desktop, so to speak. As if you were working with a "normal" computer with two screens.
Screen resolution of primary screen (that is the internal one, i.e. the panel of the notebook) at least 1280x1024 pixels, HDMI output up to 1920x1080 pixels.
An SSD hard drive is highly recommended. If only the simulator is to be operated, 256 GB capacity is sufficient.
Operating system Windows 10 Professional, new versions of the software also run on Windows 11.

Although the system will theoretically run on any computer that meets these requirements, it has only been tested and developed on the HP systems mentioned above. Unfortunately, we cannot guarantee that the system will work as intended on every computer.

If possible, the computer should be operated as a standalone system and not integrated into the company's IT. This makes both operation and maintenance much easier.

Camera and accessories

The camera consists of two individual cameras for industrial use. We produce the housing in small series using 3D printing.

The camera is connected to the laptop via two USB 3 cables. The cables are supplied in sufficient length. The camera is mounted on the construction helmet using 3D printed parts. For pig vision, the camera is attached to a rollator using specially manufactured brackets.

Outlook

At the beginning of 2023, the horse simulation was presented at the Dillenburg State Stud. In July 2024, we released the pig simulation and successfully used it at Vion Food. Since then, we have been working on developing audio software to make ultrasound audible to humans. Customers who have signed a maintenance contract will receive the updates free of charge as soon as they are released.

Source, info and support

The camera and software can be purchased from us. The conclusion of a software maintenance contract is mandatory. The contact persons are Mr. Menzel or Mr. Kellermann. We are available to answer any questions or provide price information before and after your purchase at the following address:

The system can be tested on-site by arrangement.

Seminars, lectures and company visits

If you are interested in a visit to your company, a presentation or seminar, we will be happy to assist you. Both Benito Weise and Peter Menzel offer seminars. Benito Weise specializes in the areas of cattle and pigs, while Peter Menzel covers the practical side of livestock farming and, together with Dr. Petra Hubrich, seminars for horse owners and enthusiasts.

Please feel free to contact us:

If you decide to purchase a simulator system after our visit, the price of our visit will be deducted from the purchase price.
