Wacom's Inkling is a system that digitizes and stores pen-and-ink sketches, as they're being drawn
Although E FUN may have just released its APEN, Wacom today introduced its very similar – yet different – Inkling digital sketch pen. Like the APEN, Inkling is a ballpoint pen that writes in ink on regular paper, and is combined with a small receiver that users clip to the top of the page. That receiver logs the location of the pen on the paper. When that data is transferred to a computer, a digital image of whatever was written or drawn is the result. Inkling is unique, however, in that it also incorporates pressure-sensing technology. This means that the relative line weights of the inked content will be transferred to the digital images, which makes it particularly well-suited to artwork.
