File this one away in the "man, I should've thought of that" category. Here at Mobile World Congress, Oberthur Technologies is making a name for itself by introducing the planet's first motion detecting and handset-independent SIM card. SIMSense, as it's so eloquently named, could open up a whole new world of interaction with phones that don't come with any sort of accelerometer built in. For instance, a user could simply shake their cellphone upon receiving a second call in order to send out a pre-written SMS that explains the situation. Or they could navigate phone menus by simply moving or tapping. Or, better still, they could program their handset to dial an emergency contact if it detected a sudden fall while close to the person's body. There's been no indication of anyone grabbing this thing and running with it, but we can't imagine this not making it out to the commercial realm.
