I was viewing a 1999 made hollywood lesser known movie called 'stepfather'. In the movie there is one scene in which there is a computer screen which has unknown software, unlike that is seen in india. The actress waves her hand at the screen and the application media player minimizes at her action. So i have seen touch screen pc, but i nowhere knew of anything like motion sensor GUI screen!!!?? So do the computer software/hardware makers in usa are well advanced and in india the pc system used are still of 1990s!? This technology of motion sensor might be seen in modern pc games!!!
