The device is attached to the accessory port on a Nintendo Wii*
remote control. The control is then connected to a bluetooth enabled PC
running Mojowijo software. Using Mojowijo's patent pending Motion2Vibration
technology, the device is able to transform the varying motions of the
control into appropriate vibration signals and send them to another
selected device - in the same room or over the internet. (Wii gaming
console NOT required). Essentially turning your Wii remotes into
shared, remote controlled vibrators (aka wii vibrator or wiibrator!)
In other words, the main appeal of the device isn't the capacity to use a Wii remote as a vibrator, it's being able to control others' remotely. They're on Twitter and Facebook (a mere eight people like the Mojowijo at this time!) where they say the device will also "work interactively over Skype." We assume they are referring to Skype's video chat function, which has been serving as an interactive component to non-contact sex for a while now.
The Mojowijo will be available in Fall of this year, but if you just can't stand to wait, you can sign up for a Beta test program. And if you do, let us know how it goes.
