V ÄŚeskĂ© republice doposud neexistujĂ objektivnĂ metody pro diagnostiku grafomotorickĂ˝ch potĂžà u dÄ›tĂ. ProbĂhajĂcĂ vĂ˝zkumy pouĹľĂvajĂ modernĂch digitizĂ©rĹŻ pro zachycenĂ procesu psanĂ a následnĂ© kvantifikovánĂ parametrĹŻ pĂsma. Mezi cĂli tĂ©to práce je vyvinout softwarovĂ© nástroje pro usnadnÄ›nĂ práce se sbĂranĂ˝mi daty, jako je tĹ™ĂdÄ›nĂ databáze a usnadnÄ›nĂ práce odbornĂkĹŻ pĹ™i hodnocenĂ jednotlivĂ˝ch cviÄŤenĂ. DalšĂm cĂlem práce je navrhnout a následnÄ› analyzovat novĂ© parametry on-line pĂsma na kohortÄ› dÄ›tĂ ze 2.aĹľ 4. tĹ™Ădy (n=239). V rámci práce byly vyvinuty dvÄ› desktopovĂ© aplikace na platformÄ› .NET a byly navrĹľeny a naprogramovány tĹ™i novĂ© kvantifikaÄŤnĂ parametry pĂsma zaloĹľenĂ© na principu Isochornie, dvourozmÄ›rnĂ© korelaci, a geometrickĂ©m centroidu. Všechny tĹ™i parametry vykázaly signifikantnĂ korelaci (r = [0,2; 0,3]) s hodnotami HPSQ-C u dÄ›tĂ druhĂ© a ÄŤtvrtĂ© tĹ™Ădy a korelaci v rozsahu (𝜌= [0,2; 0,5]) se subjektivnĂm hodnocenĂm odbornĂka u celĂ© kohorty. AnalĂ˝za parametrĹŻ naznaÄŤuje potĂĹľe s regulacĂ tempa pĂsma a pracovnĂ pamÄ›tĂ u dÄ›tĂ s grafomotorickĂ˝mi potĂĹľemi.
In the Czech Republic, there is currently no objective method to diagnose graphomotor difficulties in children. Ongoing research uses modern digitizers to capture the hand-writing process and quantify its parameters. The first goal of this thesis is to develop software tools to faciliate work with the collected data, such as database validation and writing exercise rating, done by specialists. Another goal of this thesis is to design new on-line handwriting parameters which are then to be analysed on a cohort of school children from 2nd to 4th class of primary school (n=239). The implementation of two desktop programs on the .NET platform is described, among three new quantifying parameters based on the principles of isochrony, two-dimensional cross-correlation, and geometrical centroid. All three parameters show significant correlation (r = [0,2; 0,3])with the HPSQ-C rating in 2nd- and 4th-graders and correlation (𝜌= [0,2; 0,5]) with specialist’s subjective scores in all children from the cohort. The analysis suggests children with graphomotor difficulties struggle with regulating handwriting speed and working memory.
