Fingerprint 2.0
Our next iteration used a touch type sensor that registers and certifies fingerprints by simply touching the home key, rather than having to swipe.
Encouraging the user to touch the sensor multiple times to increase registration accuracy was crucial. Because of technological limitations, the user had to touch the sensor 18 times or more to insure the accuracy we wanted. Part of the design goal was making this process as playful and less boring as possible.
To give the user a perception that the fingerprint was being scanned thoroughly, I took the approach of displaying an image of a fingerprint-like ink seeping on wet paper. This also helped create a more emotional impression.
Before coming up with the design concept of the fingerprint image, we took a close look at real fingerprints of people. Attention to how the friction ridges swirled, met, continued and ended helped make the design more authentic. Balance between the right amount of friction ridge waves and swirls helped bring details to the final design.
