Robo-Arm Signatures Are Legal, Gov't Buys One

AndreV writes "It's endlessly comforting to know a recently designed and implemented long-distance robotic signing arm can produce signatures legal in both the US and Canada. The aptly named LongPen replicates the handwriting from a person writing in a remote location — with the unique speed, cadence and pressure of a human pen-stroke. It started as an idea from author Margaret Atwood to help free her from grueling, multi-city, multi-country book tours, but the hard stuff was done by a bunch of Canadian haptic gurus, whose design took into consideration many factors of the human arm and how we write. How it works: from the author-end, data protocols are set up, and the pen pressure is measured on a special tablet. The data streams to the robot, while algorithms smooth out all the missed points. Complex math operations were used to help the mechatronic limb repeat the hand's motions without unnecessary jerking, and programmers had to 'scale time' or 'stretch time' by breaking down the movements, essentially tricking the eyes into thinking the robot is writing fast. It was recently adopted by the Ontario Government to sign official documents. It helps criminals sign books, too."

Re:Write once, reproduce more

Not only that, how do you know what you're actually signing if you're not there to read it in person?

You don't even need to figure out a way to store and reproduce it. Just through a piece of carbon paper under the document and have a second contract under it, or even just a blank sheet of paper to be filled out later.

With book tours, people don't just want their book signed, they want to have their 15 seconds to talk to the author.

Realistically, I suppose I'd be more likely to head down to the book store to see the weird robotic arm signing books than to talk with some random author I've never heard of.
