Graphonomics
Graphonomics is the interdisciplinary field directed towards the scientific analysis of the handwriting process, product, and other graphic skills., Researchers in handwriting recognition, forensic handwriting examination, kinesiology, psychology, computer science, artificial intelligence, paleography and neuroscience cooperate in order to achieve a better understanding of the human skill of handwriting. Research in graphonomics generally involves handwriting movement analysis in one form or another. History and conferences The first international conference relating to graphonomics was held in Nijmegen, The Netherlands, in July 1982. The term 'graphonomics' was used there for the first time. The second conference was held in July 1985 in Hong Kong and, at that meeting, a decision was taken to form the International Graphonomics Society. The IGS became a legal non-profit organization under Netherlands law on January 30, 1987. Subsequently, an international conference, s ...

Handwriting Movement Analysis
Handwriting movement analysis is the study and analysis of the movements involved in handwriting and drawing. It forms an important part of graphonomics, which became established after the "International Workshop on Handwriting Movement Analysis" in 1982 in Nijmegen, The Netherlands. It would become the first of a continuing series of International Graphonomics Conferences. The first graphonomics milestone was Thomassen, Keuss, Van Galen, Grootveld (1983). Handwriting is historically considered the widest taught motor skill. It is also one of the first, and often the only motor skill that children will learn at elementary school. It takes years of practice and maturing before a person has mastered the adult handwriting skill. Handwriting is not considered only as a movement that leaves a visible trace of ink on paper (product) but it can also be considered as a movement (process). Understanding of the handwriting product will not be complete until the handwriting process is under ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Penmanship
Penmanship is the technique of writing with the hand using a writing instrument. Today, this is most commonly done with a pen, or pencil, but throughout history has included many different writing implement, implements. The various generic and formal historical styles of writing are called "Hand (handwriting), hands" while an individual's style of penmanship is referred to as "handwriting". History Origins The earliest example of systematic writing is the Sumerian language, Sumerian pictographic system found on clay tablets, which eventually developed around 3200 BC into a modified version called cuneiform which was impressed on wet clay with a sharpened reed. This form of writing eventually evolved into an ideographic system (where a sign represents an idea) and then to a syllabic system (where a sign represents a syllable). Developing around the same time, the Egyptian system of hieroglyphics also began as a pictographic script and evolved into a system of syllabic writing ...

Questioned Document Examination
In forensic science, questioned document examination (QDE) is the examination of documents potentially disputed in a court of law. Its primary purpose is to provide evidence about a suspicious or questionable document using scientific processes and methods. Evidence might include alterations, the chain of possession, damage to the document, forgery, origin, authenticity, or other questions that come up when a document is challenged in court. Overview Many QDE involve a comparison of the questioned document, or components of the document, to a set of known standards. The most common type of examination involves handwriting wherein the examiner tries to address concerns about potential authorship. A document examiner is often asked to determine if a questioned item originated from the same source as the known item(s), then present their opinion on the matter in court as an expert witness. Other common tasks include determining what has happened to a document, determining when a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Graphemics
Graphemics or graphematics is the linguistic study of writing systems and their basic components, i.e. graphemes. At the beginning of the development of this area of linguistics, Ignace Gelb coined the term grammatology for this discipline;Gelb, Ignace. 1952. ''A Study of Writing''. Chicago: University of Chicago Press later some scholars suggested calling it ''graphology'' to match ''phonology'', but that name is traditionally used for a pseudo-science. Others therefore suggested renaming the study of language-dependent pronunciation '' phonemics'' or '' phonematics'' instead, but this did not gain widespread acceptance either, so the terms ''graphemics'' and ''graphematics'' became more frequent. Graphemics examines the specifics of written texts in a certain language and their correspondence to the spoken language. One major task is the descriptive analysis of implicit regularities in written words and texts (''graphotactics'') to formulate explicit rules (''orthography'') f ...

Letterform
A letterform, letter-form or letter form is a term used especially in typography, palaeography, calligraphy and epigraphy to mean a letter (alphabet), letter's shape. A letterform is a type of glyph, which is a specific, concrete way of writing an abstract character (computing), character or grapheme. For example, medieval scholars may discuss the particular handwritten letterforms that distinguish one script from another. The history of letterforms is discussed in fields of study relating to materials used in writing. Epigraphy includes the study of letterforms carved in stone or other permanent materials. Palaeography is the study of writing in ancient and medieval manuscripts. Calligraphy treats the letterforms of decorative writing, usually in ink. In the field of typography, type design is the process of designing typefaces that consist of sets of letterforms for use with metal print or computer. More broadly letterforms may be discussed wherever letters appear stylistically ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Writing Systems
A writing system comprises a set of symbols, called a ''script'', as well as the rules by which the script represents a particular language. The earliest writing appeared during the late 4th millennium BC. Throughout history, each independently invented writing system gradually emerged from a system of proto-writing, where a small number of ideographs were used in a manner incapable of fully encoding language, and thus lacking the ability to express a broad range of ideas. Writing systems are generally classified according to how its symbols, called '' graphemes'', relate to units of language. Phonetic writing systemswhich include alphabets and syllabariesuse graphemes that correspond to sounds in the corresponding spoken language. Alphabets use graphemes called '' letters'' that generally correspond to spoken phonemes. They are typically divided into three sub-types: ''Pure alphabets'' use letters to represent both consonant and vowel sounds, ''abjads'' generally only u ...

Jerk (physics)
Jerk (also known as jolt) is the rate of change of an object's acceleration over time. It is a vector quantity (having both magnitude and direction). Jerk is most commonly denoted by the symbol and expressed in m/s3 (SI units) or standard gravities per second(''g''0/s). Expressions As a vector, jerk can be expressed as the first time derivative of acceleration, second time derivative of velocity, and third time derivative of position: \mathbf j(t) = \frac = \frac = \frac Where: * is acceleration * is velocity * is position * is time. Third-order differential equations of the form J\left(\overset, \ddot, \dot, x\right) = 0 are sometimes called ''jerk equations''. When converted to an equivalent system of three ordinary first-order non-linear differential equations, jerk equations are the minimal setting for solutions showing chaotic behaviour. This condition generates mathematical interest in ''jerk systems''. Systems involving fourth-order derivatives or higher are ...

Acceleration
In mechanics, acceleration is the Rate (mathematics), rate of change of the velocity of an object with respect to time. Acceleration is one of several components of kinematics, the study of motion. Accelerations are Euclidean vector, vector quantities (in that they have Magnitude (mathematics), magnitude and Direction (geometry), direction). The orientation of an object's acceleration is given by the orientation of the ''net'' force acting on that object. The magnitude of an object's acceleration, as described by Newton's second law, is the combined effect of two causes: * the net balance of all external forces acting onto that object — magnitude is Direct proportionality, directly proportional to this net resulting force; * that object's mass, depending on the materials out of which it is made — magnitude is Inverse proportionality, inversely proportional to the object's mass. The International System of Units, SI unit for acceleration is metre per second squared (, \ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Handwriting
Handwriting in Italian schools (XXth - XXIst century) Handwriting is the personal and unique style of writing with a writing instrument, such as a pen or pencil in the hand. Handwriting includes both block and cursive styles and is separate from generic and formal handwriting script/style, calligraphy or typeface. Because each person's handwriting is unique and different, it can be used to verify a document's writer. The deterioration of a person's handwriting is also a symptom or result of several different diseases. The inability to produce clear and coherent handwriting is also known as dysgraphia. Uniqueness Each person has their own unique style of handwriting, whether it be everyday handwriting or their personal signature. Cultural environment and the characteristics of the written form of the first language that one learns to write are the primary influences on the development of one's own unique handwriting style.Sargur Srihari, Chen Huang and Harish Srinivasan ...

Handwriting Recognition
Handwriting recognition (HWR), also known as handwritten text recognition (HTR), is the ability of a computer to receive and interpret intelligible handwriting, handwritten input from sources such as paper documents, photographs, touch-screens and other devices. The image of the written text may be sensed "off line" from a piece of paper by optical scanning (optical character recognition) or intelligent word recognition. Alternatively, the movements of the pen tip may be sensed "on line", for example by a pen-based computer screen surface, a generally easier task as there are more clues available. A handwriting recognition system handles formatting, performs correct Segment (handwriting), segmentation into characters, and finds the most possible words. Offline recognition Offline handwriting recognition involves the automatic conversion of text in an image into letter codes that are usable within computer and text-processing applications. The data obtained by this form is reg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
