CARMEN the robot companion can help boost your memory and cognition

Have you ever walked into a room and forgotten why you’re there? Or misplaced your keys for the umpteenth time this week? If you’ve been noticing these little memory hiccups more often, you’re not alone.

As we age, our cognitive functions can start to slow down, and for some, it might be a sign of mild cognitive impairment. But don’t worry, help is on the way in an unexpected form. Say hello to CARMEN, a new robot designed to give your brain the workout it needs.

What’s CARMEN, you ask?

CARMEN stands for Cognitively Assistive Robot for Motivation and Neurorehabilitation. Fancy name, right? But don’t worry, CARMEN’s job is simple: to help people with mild cognitive impairment (MCI) sharpen their mental skills from the comfort of their own homes. This small, tabletop robot was developed by researchers at the University of California San Diego.

Think of CARMEN as a personal trainer for your brain, ready to guide you through exercises that can boost your memory, enhance your attention, and improve your problem-solving skills. What makes CARMEN special is that it’s the only robot out there that focuses on teaching compensatory cognitive strategies. In other words, it helps you find clever workarounds for cognitive challenges.

Why CARMEN is a game-changer

Here’s the deal: about 20% of folks over 65 have MCI, which is like a middle ground between normal aging and dementia. It’s not just a minor inconvenience – up to 15% of people with MCI transition to dementia each year. While there aren’t any miracle pills to stop MCI from progressing, behavioral treatments can make a real difference. That’s where CARMEN comes in. As Laurel Riek, a professor at UC San Diego and the project’s senior author, puts it: “We wanted to make sure we were providing meaningful and practical inventions.”

What can CARMEN do for you?

Imagine having a personal trainer for your brain right on your tabletop. CARMEN leads you through fun, interactive games and activities designed to boost your memory, attention, and problem-solving skills. If you need help remembering where you put your keys, CARMEN can teach you to create routine places for important objects.

If you’re struggling to keep track of appointments, CARMEN’s got note-taking strategies for that. These aren’t just random exercises. They’re part of a well-validated compensatory cognitive training (CCT) intervention, which CARMEN delivers autonomously.

The brains behind CARMEN

CARMEN wasn’t born in a vacuum. The clever folks at the University of California San Diego teamed up with doctors, people with MCI, and their caregivers to create this little robot. They wanted to make sure CARMEN would be truly helpful in real-life situations.

The team designed CARMEN with some key features in mind. It’s plug-and-play, with few moving parts, so you can use it without supervision. It works even with limited internet access. It communicates clearly and shows empathy. It gives you breaks after tough tasks to keep you engaged.

 

CARMEN in action: What do users think?

After spending a week with CARMEN, users reported trying out new strategies they thought were impossible before. Most found CARMEN easy to use and understand, though one user did find it a bit challenging. The best part? Everyone wanted more time with their new robotic pal.

“We found that CARMEN gave participants confidence to use cognitive strategies in their everyday life, and participants saw opportunities for CARMEN to exhibit greater levels of autonomy or be used for other applications,” the researchers reported.

 

The tech behind CARMEN

CARMEN is built on the FLEXI robot platform from the University of Washington. However, the UC San Diego team made significant hardware modifications and wrote all the software from scratch. They’re using ROS (Robot Operating System) to run CARMEN’s brain.

 

What’s next for CARMEN?

The team is planning to test CARMEN in more homes. They also want to teach CARMEN how to have conversations while keeping your privacy safe. This is both an accessibility issue and a response to people’s expectations of being able to talk with home systems. The researchers are also exploring how CARMEN might help people with other conditions, like ADHD.

But they’re being careful too. As Riek notes, “We want to be mindful that the user still needs to do the bulk of the work, so the robot can only assist and not give too many hints.” While we don’t know the eventual cost or exact release date yet, CARMEN’s development shows promise for accessible, at-home cognitive support in the future.

 

Similar technologies in brain training

While CARMEN represents an exciting development in cognitive assistance for those with mild cognitive impairment, it’s worth noting that it’s not the only player in the field of brain training technology. We’ve previously covered another innovative system called Sens.ai, which offers a different approach to cognitive enhancement.

Sens.ai is a 5-in-1 brain training system that uses a comfortable headset and a gamified app to help users achieve various cognitive goals. Unlike CARMEN, which is specifically designed for those with mild cognitive impairment, Sens.ai caters to a broader audience looking to improve sleep, cognition, well-being, or meditation skills.

The Sens.ai system employs a range of advanced technologies, including brainwave sensors, heart rate monitors, transcranial photobiomodulation, and objective functional brain testing. These tools work together to measure and enhance brain performance across different areas of cognitive function.

While CARMEN is still in the research phase, Sens.ai is already available to consumers, offering a free trial of its membership program. It’s backed by scientific research and has garnered positive testimonials from users.

The existence of technologies like Sens.ai alongside research projects like CARMEN demonstrates the growing interest and investment in cognitive enhancement tools. As this field continues to evolve, we may see a variety of options become available to support brain health and cognitive function for different user needs and preferences.

 

Kurt’s key takeaways

CARMEN represents an exciting step forward in how we approach cognitive health. By bringing clinically validated exercises into people’s homes through a friendly, interactive robot, we’re making brain health more accessible and engaging. While CARMEN is still in the research phase, it’s not hard to imagine a future where these kinds of AI assistants become common household helpers, especially for our aging population. They could be a game-changer in extending independence and quality of life for many people.
