Abstract
U ovom diplomskom radu opisana je izrada virtualne tipkovnice koja koristi kameru za prepoznavanje pritisaka prstiju na ravnoj radnoj površini. Sustav omogućuje tipkanje bez fiziĉke tipkovnice, uz minimalnu potrebnu opremu i jednostavno odrţavanje. LRCN mreţa prepoznaje pritiske lijeve i desne ruke te razlikuje situacije kada nema pritiska. Za potrebe treniranja neuronske mreţe, kreiran je novi skup podataka s raznovrsnim slikama ruku jer postojeći nisu odgovarali potrebama ovoga... More rada. Algoritam, razvijen u Python programskom jeziku, u stvarnom vremenu obraĊuje videozapise, prikuplja petnaest uzastopnih okvira i koristi neuronsku mreţu za prepoznavanje pritisaka tipki. Grafiĉki prikaz omogućuje interaktivno tipkanje slova, znakova, brojeva i osnovnih funkcija kao što su enter, space i backspace. Model je treniran i evaluiran na zasebnom testnom skupu, a najbolji model odabran je na temelju performansi. Testiranje s tri skupine korisnika pokazalo je funkcionalnost i pouzdanost tipkanja, uz nedostatak kao što je sporost tipkanja zbog vremenskih zahtjeva modela i kamere. Less
Abstract (english)
In this thesis the creation of a virtual keyboard is described, that uses a camera to recognize finger presses on a flat working surface. The system enables typing without a physical keyboard, requiring minimal equipment and simple maintenance. An LRCN network recognizes presses from the left and right hands and distinguishes situations where there is no press. For the purpose of training the neural network, a new dataset was created with diverse hand images, as existing ones did... More not meet the needs of this work. The algorithm, developed in the Python programming language, processes videos in real-time, collects fifteen consecutive frames, and uses a neural network to recognize key presses. A graphical interface allows interactive typing of letters, symbols, numbers and basic functions such as enter, space and backspace. The model was trained and evaluated on a separate test set, with the best model selected based on performance. Testing with three user groups demonstrated the functionality and reliability of typing, with a drawback being the slow typing speed due to the time requirements of the model and the camera. Less
