A new camera system has been developed that allows us to see the world through animals' eyes. Researchers from the University of Sussex, UK, and the Hanley Color Lab at George Mason University, U.S., created this technology.

It captures the colored world animals see in motion with over 90 percent accuracy. The system is set to revolutionize the way we understand and depict the visual experiences of different species.

Firstly, we can acknowledge that we see the world differently than animals do. This is due to their unique eye capabilities. For instance, some animals can see ultraviolet (UV) light, which is beyond the range of human vision.

So scientists figure that by reconstructing the colors that animals see, they can better understand how they communicate and navigate their surroundings. While traditional methods have provided insights into this dynamic world, they are often time-consuming, require specific lighting conditions, and cannot capture moving images.

To overcome these limitations, the research team developed a novel camera and software system that can record animal-view videos of moving objects under natural lighting conditions.

The camera records video in four color channels: blue, green, red, and UV and the data can be processed to produce an accurate video of how animals perceive these colors. In fact, the system was found to predict perceived colors with an impressive accuracy of over 92% when tested against traditional methods.

Implications of the new technology

The implications of this new technology are far-reaching. Not only will it open up new avenues of research for scientists, but it will also enable filmmakers to produce dynamic and accurate depictions of how animals see the world around them.

The system is built from commercially available cameras housed in a modular, 3D-printed casing, and the software is open-source, allowing other researchers to use and further develop the technology in the future.

"We've long been fascinated by how animals see the world. Modern techniques in sensory ecology allow us to infer how static scenes might appear to an animal; however, animals often make crucial decisions on moving targets," stated senior author Daniel Hanley in a press release.

"Here, we introduce hardware and software tools for ecologists and filmmakers that can capture and display animal-perceived colors in motion."

This remarkable achievement represents a significant step forward in our ability to comprehend and appreciate the animal kingdom's rich and diverse visual experiences.

The research paper was published in PLOS Biology on January 23 and can be found here.
