The article describes a digital camera which separates the whole of the human interaction (i.e. all controls plus the viewfinder) from the image sensor.

Digital cameras are becoming cheap and widespread, and also support video, as well as LCD based viewfinders. However, they still take the basic form of a video or still camera based on tape or film. This limits the uses of the camera.
A control device and viewfinder for a camera are typically physically located on the back of the unit that takes the pictures. In the era of digital technology, these do not have to be. However an alternative camera has two separable units. The first (CCD) unit consists of the CCD (image sensor), the flash, together with a wireless transmitter receiver and the storage device. The second (controller) unit consists of the controls (zoom, take-picture button, etc) and the LCD viewfinder as well as a wireless transmitter / receiver. The units click together in normal use, but are completely separable. Each has its own batteries/power, and they can be used within a certain range (e.g. 10m) of each other. This means that the camera can now be used in much more innovative ways. Some examples include as a video camera/viewer to monitor something out of sight; as a way of taking pictures in hard to access areas, where the viewfinder would not be visible. Potentially one controller could be used with multiple CCD units, or one CCD with multiple controllers. Taking self portraits is much simpler, even of large groups, because the viewfinder can be checked while in position.
