Difficulty with handwriting is one of the most frequent reasons that children in the public schools are referred to occupational therapy. Current research on the influence of ergonomic factors, such as pencil grip and pressure, and perceptual-motor factors traditionally believed to affect handwriting, is reviewed. Factors such as visual perception show little relationship to handwriting, wherea...

A new handwriting model is proposed for simulating complex handwriting variation in obedience to individual handwriting tendencies. Individual handwriting t,endency is represented as a set of deformation rules each of which deforms one structure of pen movements. Characters are represented as hierarchical descriptions of pen movements, so that deformation rules for various types of pen movement...

Handwriting of children in early grades is studied from the viewpoint of quantitatively measuring the development of handwriting individuality. Handwriting samples of children, in grades 2-4, writing a paragraph of text in both handprinted and cursive, collected over a period of 3 years, were analyzed using two different approaches: (i) characteristics of the word "and" and (ii) entire paragrap...

In today many students produce a wrong and illegible handwriting and teachers need a lot of time to check the handwriting errors. The traditional approach for handwriting teaching needs a long hours of handwriting practice. Unfortunately, this is not advantageous in many cases. In this paper, we develop an automated educational system for Arabic handwriting learning and detection of errors such...

Abstract Background Attention-deficit/hyperactivity disorder (ADHD) is a brain marked by an ongoing pattern of inattention and/or hyperactivity-impulsivity that interferes with functioning or development. Although children ADHD made much more spelling errors, they had distinct letter insertions, replacements, transpositions, and omissions. This mistake type sometimes referred to as graphemic bu...

The within-writer variability of handwriting forms one of the problems in the automatic recognition of cursive script. Variability can be handled by choosing handwriting features based upon the process of handwriting generation or upon computational models. Handwriting patterns are represented by a sequence of motor actions, i.e., "strokes", which can be identified by invariant segmentation. Ea...

Purpose of this research paper is to identify a person through written handwriting authentication this thesis focuses on the written handwriting authentication. Biometry offers potential for automatic personal verification and differently from other means for personal verification; biometric means are not based on the possession of anything or the knowledge of some information. Of the various b...

Poor handwriting is a diagnostic criterion for developmental coordination disorder. Typical of poor handwriting is its low overall quality and the high variability of the spatial characteristics of the letters, usually assessed with a subjective handwriting scale. Recently, Dynamic Time Warping (DTW), a technique originally developed for speech recognition, was introduced for pattern recognitio...

Cursive handwriting recognition is a challenging task for many real-world applications such as document authentication, form processing, postal address recognition, reading machines for the blind, bank check recognition, and interpretation of historical documents. Therefore, in the last few decades, researchers have put an enormous effort into developing various techniques for handwriting recog...

The present article is a review of studies concerning graphomotor functions (handwriting) in children with attention deficit hyperactivity disorder (ADHD) and the stimulant-induced (methylphenidate) alterations of both qualitative and quantitative aspects of handwriting. This review indicates an interaction between attentional functions and handwriting in ADHD children treated with methylphenid...
