Abstract
In an arrangement wherein an inquiry and a choice of respones thereto are displayed on a CRT screen, a selection is made by holding a touch-screen device against the area of the screen corresponding to the desired response. Such a touch-screen device is designed to have an inductive coil in its tip. When an electron beam which scans the CRT screen sweeps across the tip of the touch-screen device, an electrical signal is induced on the coil. The touch-position or the selection is determined based on a knowledge of the position of the electron beam on the screen at the time of the electrical signal induction.
