Summary - The article "A Reconfigurable Ferromagnetic Input Device" is about the possibilities of a new sensory device that they have discovered in their research. The authors describe the multiple new applications that could be used if the device was enhanced, such as reconfigurable input devices that could be made on-the-fly by the user and then interpreted easily by the magnetic sensing device they have come up with.
The device uses magnetic coils attached to circuitry in order to detect changes in the magnetic fields produced by the coils that are caused by the presence of ferromagnetic objects being placed on top of the device. The changes in magnetic field caused by the object create a voltage increase at the sensory input, which is then amplified and analyzed by a C# library, and then visualized by the same library.
So far, the device can only visualize objects in 2-D, but research could be done, they say, to allow it to sense in 3-D.
Shaun's Opinion - While the idea of this device is certainly appealing, at the moment its design constraints make it hard to imagine much real world usefulness. The sensing device requires the input devices to be ferromagnetic, and it only currently sees objects in 2D. While it certainly does a fine job of detecting the touch on a ferromagnetic bladder, I don't see it being very practical. This idea definitely needs more research to possibly become a useful, implementable idea.
