Inventions on GUI for Touch Sensitive Screens
This work tackles interface design problems for users of portable devices with small screens, but it appears incremental as it builds on existing touch screen technology.
The paper addresses the challenge of limited screen space for touch-sensitive interfaces on portable devices by presenting various inventions that apply inventive principles to overcome these difficulties.
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.
