Evolution Of User Interfaces For The Visually Impaired- Part- 1, Umakant Mishra
Evolution Of User Interfaces For The Visually Impaired- Part- 1, Umakant Mishra
Umakant Mishra
Physically or mentally challenged people cannot use a computer in the same way a normal people can. For example, a person with disability in hands cannot use a standard keyboard or mouse efficiently. People having hearing problem, visual challenge etc. cannot interact with a computer like a normal person. So it is necessary to specially design the computers, interfacing devices and software interfaces, which can be used by the physically challenged people.
There are many special devices like mouse, keyboard, pointers, and touch screens etc. to assist the visually challenged users. It is a challenge for the inventors and manufacturers …
Inventions On Menu Interfacing For Gui Applications, A Triz Based Analysis, Part-3, Umakant Mishra
Inventions On Menu Interfacing For Gui Applications, A Triz Based Analysis, Part-3, Umakant Mishra
Umakant Mishra
This article analyses 15 patents on Menu System from a TRIZ perspective to find out their IFRs and Contradictions. The previous two parts of this article analysed ten patents on the menu interfaces. This part analyses five more patents from TRIZ perspective and draws out the conclusion that the TRIZ process and methodology is perfectly applicable to software inventions.

Inventions On Menu Interfacing For Gui Applications, A Triz Based Analysis, Part-2, Umakant Mishra
Umakant Mishra
The first part of the article analyzed five patents on menu interfaces. This part analyses five more patents from TRIZ perspective to find out their IFRs, Contradictions and which Inventive Principles have been applied to achieve those solutions.
Using Triz To Design The Future Keyboard, Umakant Mishra
Using Triz To Design The Future Keyboard, Umakant Mishra
Umakant Mishra
A keyboard is the most common and widely used input device for a computer. Using the keyboard is often vital to interact with a computer. There are several aspects of a keyboard such as size, key layout, convenience and ergonomic features etc., which are continuously under improvement by keyboard designers and manufacturers. TRIZ is an efficient methodology in product designing. Using IFR and Trends we can well predict the directions of the future keyboards and using Contradictions and Principles we can overcome the current limitations. This article analyses the critical features of a keyboard, does a functional analysis, derives the …
An Ideal Computer Keyboard- A Case Study Of Applying Ideality On Keyboard Evolution, Umakant Mishra
An Ideal Computer Keyboard- A Case Study Of Applying Ideality On Keyboard Evolution, Umakant Mishra
Umakant Mishra
Any product or system moves towards its ideality. If we know the Ideal Final Result (IFR) it becomes easy to predict the future generation of the product or system. The author made a study of over 100 patents on computer keyboards. Each of these inventions tries to achieve some new feature or functionality. But what is the ultimate keyboard? This article makes an attempt to find the features of an Ideal Keyboard.

Inventions On Menu Interfacing For Gui Applications, A Triz Based Analysis, Part-1, Umakant Mishra
Umakant Mishra
During last two decades, the computer menu system has been improved from a text based multiple choice to highly adaptive, self organized menu system. This has been possible by hundreds of inventions. This article analyses 15 patents on Menu System from a TRIZ perspective to find out their IFRs and Contradictions. Besides we will also see what Inventive Principles have been applied to achieve those solutions.

Inventions On Computer Keyboard- A Triz Based Analysis, Umakant Mishra
Umakant Mishra
Every stage of evolution takes a product towards its ideality. This also happens in case of the Computer Keyboard. Today’s keyboards are outcome of hundreds of inventions in past. This article analyzes some interesting inventions on computer keyboard from TRIZ perspective. The inventions improve various aspects of computer keyboards like increasing operating (typing) efficiency, reducing size, improving ergonomic features and so on. This article was first published in TRIZ Journal (http://www.triz-journal.com/archives/2003/11/) in November 2003.
