University of Illinois Students Are Making a Talking Dog Collar
Meet Alma ‘The Talking Dog’ and the humans that are letting her speak
The project is called “Dug the Dog IRL,” and it’s a wondrous mix of nerdy, fascinating, and adorable. A prototype of the technology will be on exhibit at the University of Illinois Engineering Open House.
The team behind the project says the concept is based on the talking dog collars featured in the Pixar movie Up. Instead of Dug, though, the team is testing the project on an exceptionally well-trained yellow lab named “Alma,” after the famous Alma Mater statue on the University of Illinois campus.
To learn more about Alma and her talking collar, I sat down with Dug the Dog IRL team members Amanda Maher, Matthew De Venecia, and Bliss Chapman.
If you want technical explanations of the project, you can read the “Project Dug” article that the team has published on GitHub or this article they used as a resource. For an abridged version, you can watch the video below.
The concept is simple. Information in the form of electrical signals from Alma’s brain is picked up by electrodes. Circuitry amplifies the information and miniature computers on Alma’s back correlate it to a specific stimulus that she is experiencing. If a familiar pattern is recognized, a speaker plays a recording that is associated with the emotions the dog is likely experiencing.
In this case, the group has chosen the stimulus of offering Alma a treat. When Alma sees the treat, the electrodes pick up a signal of excitement and the speaker plays the words, “Oh! Treat! Treat! Yes, I want the treat. I do so definitely want the treat. I would be very happy if I were to have the treat!”
Amanda Maher, a junior in Mechanical Engineering, says she was drawn to the idea out of her love for animals. She describes the project as “listening in” on signals from Alma’s brain.
One of the difficulties Maher says the team has faced is making sense of the raw electrical data from the custom 3D printed electrodes. Most electrodes by default have a “pre-program” that is already attached to them when they are purchased that makes their usage a bit simpler. With the custom electrodes, no pre-program exists. This added an extra level of difficulty for the team.
Maher would like to go on the record saying that, “Alma is a really good girl.”
Matthew De Venecia, a senior in Bioengineering, and Bliss Chapman, a senior in Statistics and Computer Science, both say that shielding wires from electrical interference was an unexpectedly critical step.
The signals that the electrodes receive from Alma’s brain are very weak. The cables that travel from Alma’s head to the high-tech harness on her back (where computing takes place) can be bombarded with outside electrical activity. Even small disruptions can muddle the reading of Alma’s brain signals.
To mitigate this problem, the team had to take steps to braid the wires and coat them in nickel to reduce interference.
Dug the Dog IRL is not the first group with the idea. A startup called “No More Woof” developed the idea a few years back and put out three versions of a product for $65, $300, and $1,200 — priced based on how many different signals the product can recognize and how complex the outputs are.
It’s likely that No More Woof is no more, as they have not responded to my request for comment asking whether they still exist.
Overall, the Dug the Dog IRL group estimates that, if they hadn’t had any of the supplies previously, their prototype would cost about $180 in materials.
De Venecia sees a future for the technology with humans. He says that because the technology is able to take brain inputs and create an event, it could eventually be used to make highly advanced prosthetics.
Taking this to an extended degree, he says it could allow people to accomplish complex tasks like typing or driving a car with just their thoughts.
De Venecia also anticipates veterinary applications. He says that currently, “A vet can’t just ask a dog, ‘Hey, where does it hurt?’” With this technology, better vet-animal communication is possible.
Chapman says the tech could one day “unlock high-bandwidth communication with other species.” He believes this would give humans an entirely new lens to view the world, as it will offer a glimpse into the minds of animals.
He wrote in an email:
We often assume what we see is how the world is, but science continually shows us how wrong that assumption is. Other species have entirely different sensory systems and often see the world much differently than we do. I, for one, would love to hear more about their perspective.
Alma, the dog, could not be reached for comment on this story.
