How great would it be to be able to label things by hand -legibly?
Today’s invention is a stylus at the ‘writing’ end of which is a small dot matrix-type array. The user can specify what font is required and even perhaps the ink colour verbally…a mic in the stylus picks up the instruction and adjusts the internal settings accordingly.
Then the user places the stylus on some paper, a piece of fruit or whatever and says “The quick brown fox…” The stylus then propels itself along the surface (driven by a motorised internal wheel and still loosely held by the user, or not).
Beautifully printed text can thus appear on command.
