Using Triz For Maximizing Information Presentation In Gui, Umakant Mishra

Umakant Mishra

The modern software tools provide numerous graphic elements in their GUI, which demand more and more screen space. As the size of a display screen cannot be extended beyond a limit, it is typically seen as a constraint in a graphical user interface.

Looking from a TRIZ perspective, the computer screen should display all the information that the user needs (Ideal Final Result). There are various methods of addressing the problem of screen space, some of which are, ”using icons for windows”, “the desktop metaphor”, “the large virtual workspace metaphor”, “multiple virtual workspaces”, “overlapping windows” and “increasing dimensions” etc.

Using Triz To Improve Navigation In Gui, Umakant Mishra

Umakant Mishra

A typical user interface consists of several buttons, menus, windows, trees and other type of controls. The increased number of GUI elements and complexities of the GUI controls necessitate the user to acquire certain level of skill and efficiency in order to operate the GUI. There are many situations which further make the navigation difficult. Ideally the user should face no difficulties in navigating through the user interface. Any operation in the graphical user interface should require minimum pointer operations from the user (Ideal Final Result). This objective of a graphical user interface has led to several inventions trying to …

Using Triz For Minimizing Cursor Movements In Gui, Umakant Mishra

Umakant Mishra

Although a GUI is a revolutionary development over its predecessors, it suffers from a typical shortcoming that it requires a lot of pointer movements. As pointer movement is a slow process it affects the overall performance of a GUI operation. Besides too much pointer movement can frustrate a user. Hence, it is desirable to reduce the pointer movements while performing any action through a typical GUI. Ideally the user need not move the pointer to initiate a GUI based operation. In other words the pointer itself should automatically move onto the desired location on the graphical user interface (Ideal Final …

Ideally the GUI should prevent users from doing any mistake while operating …

Arranging Display Of Gui Elements- A Triz Based Analysis, Umakant Mishra

Umakant Mishra

One of the biggest drawbacks of the graphical user interface is that it consumes the active display area associated with the device. Whether the display screen is a part of a television, computer, or any other consumer device, the graphical user interface appears on the active area of the display screen. As a result the GUI masks a part of the display screen and the amount of information that can be viewed on the screen is reduced. Ideally the GUI should offer all its features without blocking any part of the display screen. The features should be readily available and …

Inventions On Three Dimensional Gui- A Triz Based Analysis, Umakant Mishra

Umakant Mishra

The graphical user interface has become popular because of its simplicity and user friendliness. The user can do very complex operations through GUI by simple pointer movements.

Adding another dimension to a graphical user interface can yield tremendous benefits such as improving aesthetics, data presentation, screen-space utilization and user friendliness. The user can easily locate the objects in …

Inventions On Auto-Configurable Gui-A Triz Based Analysis, Umakant Mishra

Umakant Mishra

A GUI is intended for the end user but designed by the developer. Even the experienced developer cannot realistically anticipate what options will be required by the users at a future point of time. Besides, even a well-designed GUI may not be felt convenient to all categories of users as the skill, expertise and requirement of the users vary from each other.

Although the user can best describe his requirement and therefore can best configure the GUI, it is not advisable for the user to spend time and effort to configure the GUI. The user interface needs to be customized …

Inventions On User Configurable Gui- A Triz Based Analysis, Umakant Mishra

Umakant Mishra

The graphic user interface is a revolutionary development over the prior art technique of the command line interface. Using GUI the user can do even complex operations through simple means like clicking buttons or dragging various graphic elements.

Ideally the GUI should contain all those buttons (or menu items or other GUI elements) and only those buttons (or menu items or other GUI elements) that the user needs. Besides the GUI elements should not obscure the display of data, should take no time for searching and should create no confusion in any level of user. Generally the GUI elements are …
