But the bug in our case was in touch-sensitive displays: we wanted to be able to draw -- you know, rub your finger across the screen to input continuous points -- and there was just too much friction created between your finger and the glass -- if glass was the substrate, which it usually is.
Mas o bug no nosso caso estava em telas sensíveis ao tato. Queríamos ser capaz de desenhar, sabe, esfregar o dedo através da tela de entrada de pontos contínuos. E não havia atrito demais criada entre o dedo e o vidro - Se o vidro for o substrato, o que é o habitual.
