Using a special camera that combines high-speed vision and two rotational mirrors, Masatoshi Ishikawa and his team at the Ishikawa Oku Laboratory here say they’ve found a way to project a device’s display screen or keyboard onto the palm, or any other surface, so that you can operate it remotely in your home or office. Ishikawa says the system can detect the movement of a three-dimensional object every two milliseconds. Put simply, the high-speed vision allows the program to track moving objects, so users would be free to walk with the phone image in palm, without the display ever shifting. The projection causes a faint tingling sensation in the palm when keys are pressed but this only adds to the authenticity of the technology. In a related experiment, Ishikawa tracked the movement of a ping pong ball down to the millisecond. This type of technology can be used to track lightning fast objects and hence can be applied to research in medical and gaming fields. The computer system beams ultrasonic wave emitters, so users actually feels the keyboard pressing against their skin, without anything in their hand. The sensation is similar to holding a 3 gramme object. – See more at Ishikawa says his system is far more advanced than anything featured. Ishikawa now hopes to perfect the projection phone, so users can dial from their palms, and view 3-D images. The phone is strictly for indoor use only, and he doesn’t expect the complete system to be on the market for at least 5 to 6 years
