Finding the right fit for a half-mask can be challenging, but Size 4 Face makes it easier with advanced augmented reality (AR) and precise facial measurement technology. By leveraging ARCore and Augmented Faces API, the app digitally scans the user’s face to suggest the most suitable mask size—enhancing both comfort and protection.
We had to build an algorithm capable of measure digitally scanned faces, possibly in the most accurate way.
Plus, we had to take into account that the mobile phone camera is imperfect. Provided scans could have some errors in measurements. Another part of that challenge was that none has ever made such an app before.
To tackle these challenges, we developed an advanced algorithm capable of accurately measuring digitally scanned faces while compensating for potential camera imperfections.
We refined the face dimensioning function to minimize measurement errors and leveraged augmented reality (AR) to improve precision. Additionally, we designed a simple and intuitive UI to ensure ease of use, making the technology accessible to all users.
It was an honor – to build an application that soon can influence the future of many people. Such pleasant view – to see the technology ministering to people and making life a little bit easier. We love such projects. The interesting fact is that during creating CIOP, we have made use of Augmented Faces. This technology is more known for making fun with it. But we have used it to generate a digital 3D mask. Our app does not always recommend the best possible sized mask. The result still needs to be approved by a human. However, an application like this is a giant leap towards a brighter tomorrow.
