It is common for people to use a sequence of the same numbers to unlock their phone. People use simple passwords for various reasons - one of the reasons being that it’s quick. Ironically, that defeats the purpose of having a password that is hard to crack. Can’t fingerprint recognition, which is more secure and simple, be an effective alternative to tapping numbers?
Goal of the project
Accurately register fingerprints and
quickly unlock the device with ease
Fingerprint 1.0 registers fingerprints by swiping the sensor built in the home key, where as the 2.0 registers by touch. Although sensors are activated differently, the underlying mechanisms are similar.
Registration
Provide an easy-to-use guide so that users can correctly register.
Certification
Minimal affordance helps easy certification.
Feedback
When there is a match, rather than showing that certification has been successful and go straight to the next page.When there is no match or when recognition has failed, suggest cause of the failure and guide the user to re-do it the right way.
Fingerprint 1.0
(Swipe to unlock)
Providing a visual cue to swipe downward of home key was effective. The visual cue was placed near the home key. An simplistic motion graphic was necessary to provide GUI and direction.
The design included a series of dots with motion to swipe downwards instead of a fingerprint-shaped design to suggest to the user the action required. The dots grow larger towards the bottom of the screen and if the user presses his finger on the sensor, the dots gather unsuccessful, the dots bounce back toward the center. When to their initial position.
