How can a User control the quality of a FaceScan?

The quality of a FaceScan can often rely on the User.

There is no set preference as to whether a User should hold the smartphone in their hand or place it on a steady surface during the scan. However, the smartphone must not be continuously moving around during the scan.  

It is advised that the User find a steady surface, and have the phone face a clear uncluttered background, allowing the User to focus purely on lighting and face alignment within the on-screen circle.  

Elements that could make a scan unsuccessful:

  • Heavily applied make-up, freshly applied sunscreen, or creams.  
  • Accessories around the face like hats, scarves, or glasses.  
  • Poor lighting or uneven lighting. TOI technology needs a human's whole face illuminated well and evenly. Users with half a shadow across their face may encounter unsuccessful results. A User may need to move closer to light or change settings if the lighting is not adequate.  
  • Multiple faces on screen. FaceScan was designed to capture the face of one person, not multiple. Any additional faces on the screen will confuse the technology and deliver inaccurate results.  

While it’s not a requirement, Users can also use ring lights to successfully illuminate their face. During FaceScan trial and validation studies, it was found that ring lights are the best method of achieving optimal illumination of the face.
