The design captures speech through a small microphone, where an AI model translated and converted it into written text in real time.

The translated text was then sent over wi-fi Fi via a “microcontroller” which Milya said “sends signals from one thing to another”.

She explained the controller was, in essence, “a small computer, and that’s how the language is detected and also translated”.

The text is reflected through a mirror, lens and reflector, appearing like subtitles in the user’s field of view, she said.

Milya said the device was more accurate if programmed for a specific language – but was also not just helpful for understanding foreign languages.

She said: “Besides translation, it’s really good at transcription.

“So, people hard of hearing can have a subtitle display.”
