Handwriting movement analysis Save Handwriting movement analysis is the study and analysis of the movements involved in handwriting and drawing. It forms an important part of graphonomicswhich became established after the "International Workshop on Handwriting Movement Analysis" in in Nijmegen, The Netherlands. It would become the first of a continuing series of International Graphonomics Conferences. Handwriting is historically considered the widest taught motor skill.
History[ edit ] The first electronic handwriting device was the Telautographpatented by Elisha Gray in The RAND Tablet employed a grid of wires under the surface of the pad that encoded horizontal and vertical coordinates in a small magnetic signal.
The stylus would receive the magnetic signal, which could then be decoded back as coordinate information. The acoustic tabletor spark tablet, used a stylus that generated clicks with a spark plug. The clicks were then triangulated by a series of microphones to locate the pen in space.
Digitizers were popularized in the mids and early s by the commercial success of the ID Intelligent Digitizer and BitPad manufactured by the Summagraphics Corp.
The ID model was the first graphics tablet to make use of what was at the time, the new Intel microprocessor technology. This embedded processing power allowed the ID models to have twice the accuracy of previous models while still making use of the same foundation technology.
This lower cost opened up the opportunities for would be entrepreneurs to be able to write graphics software for a multitude of new applications. These tablets used a magnetostriction technology which used wires made of a special alloy stretched over a solid substrate to accurately locate the tip of a stylus or the center of a digitizer cursor on the surface of the tablet.
This technology also allowed Proximity or "Z" axis measurement. Though originally designed for the Apple IIthe Koala eventually broadened its applicability to practically all home computers with graphic support, examples of which include the TRS Color ComputerCommodore 64and Atari 8-bit family.
Competing tablets were eventually produced; the tablets produced by Atari were generally considered to be of high quality. Passive tablets Passive tablets,  most notably those manufactured by WacomHuion and Parblofor example, make use of electromagnetic induction technology, where the horizontal and vertical wires hanvon 5 e reader with handwriting analysis the tablet operate as both transmitting and receiving coils as opposed to the wires of the RAND Tablet which only transmit.
The tablet generates an electromagnetic signal, which is received by the LC circuit in the stylus. The wires in the tablet then change to a receiving mode and read the signal generated by the stylus. Modern arrangements also provide pressure sensitivity and one or more buttons, with the electronics for this information present in the stylus.
On older tablets, changing the pressure on the stylus nib or pressing a button changed the properties of the LC circuit, affecting the signal generated by the pen, which modern ones often encode into the signal as a digital data stream.
By using electromagnetic signals, the tablet is able to sense the stylus position without the stylus having to even touch the surface, and powering the pen with this signal means that devices used with the tablet never need batteries.
Activslate 50, the model used with Promethean white boards, also uses a hybrid of this technology. These styluses rely on an internal battery rather than the tablet for their power, resulting in a bulkier stylus. Eliminating the need to power the pen means that such tablets may listen for pen signals constantly, as they do not have to alternate between transmit and receive modes, which can result in less jitter.
Optical tablets Optical tablets operate by a very small digital camera in the stylus and then doing pattern matching on the image of the paper. The most successful[ citation needed ] example is the technology developed by Anoto. Acoustic tablets Early models were described as spark tablets—a small sound generator was mounted in the stylus, and the acoustic signal picked up by two microphones placed near the writing surface.
Some modern designs are able to read positions in three dimensions. Scriptel's designs are one example of a high-performance tablet detecting an electrostatic signal.
Unlike the type of capacitive design used for touchscreensthe Scriptel design is able to detect the position of the pen while it is in proximity to or hovering above the tablet.
Many multi-touch tablets use capacitive sensing. Compared to touchscreens, a graphic tablet generally offers much higher precision, the ability to track an object which is not touching the tablet, and can gather much more information about the stylus, but is typically more expensive, and can only be used with the special stylus or other accessories.
Some tablets, especially inexpensive ones aimed at young children, come with a corded stylus, using technology similar to older RAND tablets.
The puck's external copper coil can be clearly seen. After styluses, pucks are the most commonly used tablet accessory. A puck is a mouse-like device that can detect its absolute position and rotation.
This is opposed to a mouse pointing devicewhich can only sense its relative velocity on a surface most tablet drivers are capable of allowing a puck to emulate a mouse in operation, and many pucks are marketed as a "mouse".
Pucks range in size and shape; some are externally indistinguishable from a mouse, while others are a fairly large device with dozens of buttons and controls.
Professional pucks often have a reticle or loupe which allows the user to see the exact point on the tablet's surface targeted by the puck, for detailed tracing and computer aided design CAD work.
Embedded LCD tablets[ edit ] Digital graphic tablet or drawing board with integrated LCD screen Some graphics tablets incorporate an LCD into the tablet itself, allowing the user to draw directly on the display surface.
Unlike touchscreens, they offer pressure sensitivity, and their input resolution is generally higher. This often allows for increased accuracy and a more tactile, "real" feeling to the use of the device. The graphic tablet manufacturer Wacom holds many intellectual property patents on key technologies for graphic tablets,  which forces competitors to use other technologies or license Wacom's patents.
The displays are often sold for thousands of dollars. Some commercially available graphic tablet-screen hybrids include:The target audience for the Hanvon N is slightly different though and is why it differs so significantly from those two readers: • Smaller than the Kindle, the Hanvon reader has rough dimension of 6 x x inches and is under ounces in weight making it one of the lightest reader around.
