Ntt DoCoMo UbiButton
22 July 2004 by axxxr Ntt DoCoMo have introduced a product called the "UbiButton". It is attached to the wrist much like a wristwatch, and by only snapping the fingers,and it could be used to turn on and off a light.and other future mobile applications.
The senior chief engineer, Masarou Fukumoto, gave an explanation on the technology: "it has an internal single axis acceleration sensor, which recognizes the frequency of waves generated by the snapping of the fingers. These frequency of the waves represent the sound that can be heard by putting your arm up to your ear, then hitting it with your fingers - we call this 'shock acceleration.' By including only a simple shock sensor, there could be times when the switch is triggered by only swinging the arm; we've made it so that only an impact will trigger the switch. Though this technology does not have much to do with cellular phones, it "will be an easy to understand interface" for the corporations of the future. |
