Abstract:
A touch sensitive screen displays the information on the
screen and also receives the input by sensing a user’s touch on the same screen.
This mechanism facilitates system interaction directly through the screen
without needing a mouse or keyboard. This method has the advantage to make the
system compact by removing keyboard, mouse and similar interactive device.
However there are certain difficulties to implement a touch
screen interface. The display screens of portable devices are becoming smaller
thereby leaving lesser space for display of data, menu or touch screen
interaction. Besides some screens need to display so much of information that
they hardly can afford any space to display touch screen buttons. This article
illustrates various inventions which have successfully eliminated these
difficulties by applying appropriate Inventive principles.
