Cell Phones: The Next Generation

Inventors said phones of the future will not just get smaller, but they will use your body as an extension of the phone. The finger whisper is a wearable phone in development that will send vibrations up your finger to make and receive calls.

Inventor Masaaki Fukumoto explained that the key to the phone uses a microphone and receiver placed on the tendon in your wrist.

"This phone uses bone conduction," he explained. "The vibrations travel up your finger and echo in your ear canal, so it's the only sound you hear."

NTT Docomo envisions a world where videophones are sewn into clothing or used for an impromptu medical examination on the road.

Godo Irukayama explained that a phone will soon be able to keep an eye on your home while you're away -- closing curtains and turning on lights at the touch of a button -- all monitored by video on your phone.

It also tells you when an intruder has broken into your home so you can send him a message.

"Pretty soon, the only thing you will need when you walk out the door is a phone and a handkerchief. You can shop with your phone, organize your schedule, monitor your home, everything," Irukayama said.

Irukayama insists that the new phones will not just benefit humans. In consumer tests, feeding your pet through your phone was one of the most popular uses.
