It will be appreciated that many forms of pen can be produced in for use in this invention and that in addition existing computer input devices can be adapted to embody the invention herein described. However, such keyboards have not been successful possibly due to the barrier of having to learn a new way of typing which overrides the advantages of such a simple keyboard.
The signal abstracted preferably corresponds to a quantization of motion as the character is drawn.
The pen tip 64 may include a suitably shaped rubber or the like pad which is relatively non-slip upon say a table. The study of handwriting as a neuromuscular activity, its development as a skill and the effect upon it of various and external factors.
With character constructing keyboards as mentioned above, a number of fingers must be employed simultaneously to print a character and so co-ordination skills must be learned by the user. Obviously the writer will have to adapt the writing of each character to produce just the unit vectors required for error free recognition.
In many devices currently available this function is performed by a pen or stylus moved by the fingers across a touch sensitive screen. Class characteristics The handwriting characteristics reflected in a group of individuals and are learnt by the child at the onset of learning to write.
The logic of the start signal may be handled electronically. Such a derivation is suited to the application of this invention to conventional computer pointing equipment.
The apparatus generates a code for the character being drawn as a time dependent sequence of signals by comparing the characteristics of the movement as the character is drawn with a predetermined set of characteristics, with each signal corresponding to the predetermined characteristic closest to the actual characteristic detected at each successive step of movement.
The unit vector detected causes the image displayed of the pointing device movement to be locked to the corresponding direction and allows the input of a line reproduced on the screen that represents the extension of the movement.
It is important to realise that the locus of the pen body is invisible. Means as claimed in claim 1wherein the drawing means comprises a hand-held pen-like device.
Such characters can build up to display a completed word, for example, in a standard, clear, joined-up cursive writing, each character of which has been produced from the sequence of simple elements produced by or abstracted from the operation of the input device. The signalling of the end of a word may be achieved by pen lift activating a switch or sensor or other eg button press, or a special unit vector sequence or special movement sequence.
One further embodiment of the invention is a pen device shown schematically in FIGS. Means as claimed in claim 12wherein the drawing means is arranged to signal completion of a character by lifting the drawing means from a drawing surface. According to one aspect of the invention there is provided means for inputting a hand generated character into a computer comprising means for drawing a character, means for abstracting a sequence of signals as the character is drawn corresponding to components of the character to produce a code representative of that character and means for recognising that code, whereby the character is inputted to the computer.
Such an arrangement as shown in section in FIGS. The feedback thus guides the writer in a most natural way to input the correct sequence of unit vectors, without consciously having to pay attention to that level of analysis.
Retrieved from " http: The graphic simulation is preferably modifiable in response to a subsequent signal of a sequence for a character. Alternatively, the sequence can be transmitted directly for simple logical recognition therein.
Alternatively, the sequence can be transmitted directly for simple logical recognition therein. Means as claimed in claim 22wherein at least one movable part of the device is a tip movable relative to a body of the device and one or more flexible linkages affect movement of the tip relative to the body.
They are rather the result of an analysis of the movement etc which indicates a series of unit vectors. The printing press sets up its text as a block of lead type which is impressed onto one or more paper pages at a time. This allows the user to judge more accurately the movements required to cause correct unit vector recognition, as confirmed by the display of the corresponding animated font elements, for example, corresponding to the input of a drawn letter "o".
Handwriting identification There are two fundamental fields of study pertaining to handwriting: With character constructing keyboards as mentioned above, a number of fingers must be employed simultaneously to print a character and so co-ordination skills must be learned by the user. Process of underlying identification The careful and systematic use of evidence, which is common to the many disciplines of forensic science, is directed toward the identification of an unknown.
Note that the spine rod and the template dimensions can be many times larger than the effective template size. Alternatively, completion of a character may be indicated by a unique movement of the drawing means relative to that character.This invention concerns means for inputting characters or commands into a computer or other information receiving device without a keyboard or the like using the automatic skills of.

The letters are like guardsmen on parade. The forward movement of the pen looks as though it has been carefully restrained. The writing does not flow, and there is no sloppiness or freedom of movement in the writing. where there has. handwriting analysis that indicates circular movement of the pen in a clockwise direction indicates _ handedness under the trace over method places the document to be forged _ under the paper containing the authentic signature.
