Masaaki Fukumoto, director of the biological signal-processing laboratory at NTT DoCoMo's multimedia laboratories, shows off the FingerWhisper (Yubi-Wa), a wearable mobile phone prototype that utilizes the human hand as an integral part of the receiver. The FingerWhisper, which is being exhibited for the first time outside Japan, works by requiring its user to stick a finger into his or her ear. Worn on the finger, the Bluetooth-enabled terminal converts voice to vibration through an electro-mechanical actuator and then channels the vibration through the hand's bones to the tip of the user's index finger. Booth No. 3L2-7.
