An anonymous reader writes "A company claims it has the technology to make writing on touchscreens more like writing with pencil and paper, when the harder you press the thicker the line you produce. The technology uses a material called Quantum Tunnelling Composite (QTC), the resistance of which is extremely sensitive to pressure, unlike today's touchscreen phones, which might be fine for basic finger-pointing, but they are poor at gauging the pressure of the touch. The hope is that this will be useful in Asia for handwriting recognition, because Asian scripts use a lot of variation in line thickness. Interestingly, screens with a standard 2D touch matrix can get the extra measure of control using a narrow strip of QTC down the side. Something for future iterations of the iPad, perhaps?"
