The University of Siena has created a ring that enables discussion with artificial intelligence without the use of screens or keyboards that disrupt the flow of communication between two interlocutors, ushering in a new era of human-machine interfaces: AI as a direct extension of the human brain. The idea, titled "Wearable device for contextual cognitive enhancement through a sensorimotor interface", was recently patented by the University of Siena and is the outcome of research coordinated by Professor Domenico Prattichizzo, four inventors, and a dozen researchers. The item is an intelligent ring that allows you to activate and receive responses from artificial intelligence systems like Claude or ChatGPT in real time, quietly, and without disrupting the flow of communication. This minimalist and practically undetectable interface fundamentally alters the relationship between humans and technology. "The ring", says Professor Prattichizzo, "allows us to better integrate artificial intelligence with natural human intelligence through a sensorimotor interface". The system is based on continuous contact between the user and the system. AI uses headphones or microphone-equipped eyewear to analyze conversations in real-time. A brief press of the ring identifies the exact instant in the audio stream, and the time tags that are generated are employed to extract the AI prompt from the audio. When the user needs aid in retrieving a word, data, or information, they engage the system with a single touch. The AI processes the request and vibrates to notify when it is ready. "The device not only extracts the prompt from an audio sequence with a tap on the ring, but also receives information", Prattichizzo says. "When the AI's response is ready, the ring signals it with a vibration". At this point, it's always up to the user to decide when to listen to it: a second gesture allows them to receive it via earbuds without interrupting the discussion with the other person. This method allows for seamless communication, making engagement with AI feel more natural. This ring's applications range from everyday use to highly specialized situations. The technology could help people with linguistic or cognitive impairments, such as aphasia or Alzheimer's, as well as professionals in situations that require quick access to information, all while maintaining the naturalness of the encounter.
