Motion-Based Cell Phone Unlock

kddi-custom

By Evan Ackerman

Remembering and entering passwords in anything is a major hassle, which is why everything should have seamless biometric identification built in. Failing that, KDDI has come up with a gesture based system that at least eliminates annoying number codes. Using an accelerometer, the phone looks for a specific pattern of movements as you bring it up to your ear. These movements depend on things like arm length, muscle structure, and patterns such as holding methods and other habits. According to KDDI, the error rate is only 4%, which is easily good enough for casual use.

As far as I can tell, there’s no reason why something like this couldn’t be implemented into any phone with an accelerometer, even without KDDI’s fancy arm length etc. analysis software. You just have to turn the phone on, and shake shake shake it in a particular way, and it’ll unlock. KDDI eventually plans on taking this technique a little further, allowing you to use specific motions to run programs or unlock your porn folder.

    I tried to call KDDI's tech support but they were busy helping Michael J Fox try to unlock his phone.

    rofl that's what I was thinking about!

    1st. The idea of shaking for locking/unlocking your cellphone is rather old (e.g., ShakeLock)
    2nd. Does it mean that I cannot use my left hand to unlock/pickup my cellphone if I “practiced” doing that with my right hand?
    3rd. Amazing, it can allow “you to use SPECIFIC MOTIONS to run programs or unlock your porn folder” … lol
