(2 Mar 2022) LEAD IN:
The tech innovations of the future are vying for investment at trade fair Mobile World Congress.
Startups have their own dedicated space called Four Years From Now.
STORY-LINE:
How good is Rafael Ramirez at playing the violin?
A computer will soon tell him.
Ramirez is Associate Professor in Music and Machine Learning Lab at University Pompeu Fabra and was part of a project to create SkyNote, software that can teach users how to play musical instruments.
Sensors feed SkyNote data so it can assess sound quality, pitch, timing, posture and even his bowing technique.
Green shows were he's played a note correctly - but if it's red, it indicates he didn't hit the right note.
"Our system is based on audio analysis and motion capture analysis using machine learning techniques, artificial intelligence techniques. What we do is to take the raw audio from the musician and we feed it to a neural network, a deep neural network, to extract features, interesting features, for the task we want to come back to do. For example, for sound quality, the system, the algorithm extracts features that are useful to detect if you are playing a good sound, a bad sound, a bright sound, warm sound. What kind of sound you are playing. And it gives you feedback on that," says the professor.
Ramirez has brought SkyNote to 4YFN (Four Years From Now) at Mobile World Congress Barcelona.
It's an area where startups like this can network and meet potential customers and investors.
Ramirez says his group is looking for an investment of 400,000 to take this from an academic project to a commercial success.
He says its musical success has already been proven.
"What they did at the Royal College of Music, they took the really high level of students, not even beginners that were practicing with the technology," he explains.
"Even in a 10 minute session, we were shown that the students practicing with technology improved significantly more than the students without the technology."
Kokoon's sleep headphones are another startup at the event.
The company started life back in 2013, with it first product - an over-ear headset - available from 2018.
A new in-ear alternative went on the market in September last year.
So far, Kokoon has sold around 60,000 over ear sets and 10,000 of the latest product.
Their creator was inspired by his own problems with sleep problems.
"The way to find the technique that helps you get to sleep is to look at your brain wave function. So he developed a product that would look at the brain wave function to get an understanding of what the issues are to go to sleep. But also when you find a particular type of therapy that helps for you, you need to find a product that you can sleep in in order to be able to listen," says Sian Hannah, Global Sales Director, Kokoon.
An app provides users with analysis of their sleeping habits and has an audio library of tracks developed by sleep clinics to help users doze off.
It's this part of the business that Hannah expects to focus on next.
"I think one of the business goals for the future would be looking at the app because at the moment you don't have access to the app unless you physically bought a product. So in the long term, we'd be looking at a subscription model so that other people can have access to the app to use with other devices," she says.
The pandemic has made video conferencing a familiar part of our working lives - and even our social lives too.
But what if you could meet up in 3D form, instead of inside 2D boxes.
Javier Bello's company Imverse is making that a reality.
It works on a subscription model.
