A smartwatch that secretly tells you when the other person is lying during a conversation: AI instantly fact-checks: Innovative Tech (AI+) - ITmedia AI+
Researchers from the University of Auckland in New Zealand and the National University of Singapore have proposed a smartwatch that can instantly distinguish between facts and falsehoods in everyday conversations.
Have you ever wondered if a conversation with family or friends, or a post on social media, was true? Wouldn't it be very convenient if you could immediately tell whether the content of a conversation was true or not?
This time, we will introduce "Factually," a cutting-edge technology that combines AI and a smartwatch to tell you the accuracy of information in real time. We will explain in an easy-to-understand manner how it works, how to use it, and what fields it can be useful in.
How a smartwatch can detect lies
AI analyzes voice on the spot
Factually will be installed in wearable devices such as smart watches and smart rings. It listens to conversations with a microphone and converts them into text using voice recognition. This is then analyzed by AI (large-scale language model) and compared with reliable information to determine the authenticity of the content.
"Secret" feedback via vibration
If you lie or make a mistake, the smartwatch will notify you with a specific vibration, without sound or visual indication, so you can check the accuracy of the information discreetly.
How do you keep up to date?
Factually's backend is designed to keep you up to date with the latest information.
- Get news and data automatically: Get the latest information instantly by referencing NewsAPI and government statistical data.
- AI integrates and evaluates information: Cross-references multiple reliable sources and displays accuracy with a score and commentary.
- Models and sources are updated regularly: If new technology is released, it will be automatically reflected.
- Respect your privacy: Audio data is processed on the device and deleted immediately after analysis.
The possibilities for use are endless!
This technology can be applied to a wide range of fields, not just health and entertainment news, but also finance, business, education, etc. For example, if you can verify the veracity of stories about investments, you can prevent mistakes in judgment.
It can also be used for language learning and quiz apps, allowing you to acquire correct knowledge on the spot.

Related technologies of interest also appear
Recently, technologies such as "LiveFC" have been introduced, which allows for real-time fact-checking of live broadcasts and voice chats. It is expected to become a technology that will support accurate information in more situations in the future.
My Feelings, Then and Now
- AI and smartwatches vibrate to alert you to lies and misinformation during conversations
- Real-time analysis with speech recognition and large-scale language models (LLM)
- Always refer to the latest information to support accurate decision making
- Notify without sound or screen, without being noticed by others
- Applications are possible in a variety of fields, including health, economics, and education
AI fact-checking technology gives us the power to "select correct information." In the future, the ability to make judgments without being misled by information will become increasingly important in society.
Why not start cultivating the ability to discern the truth now? Let's grow together with technology so that we can make better choices for our futures.
