The Revised 40 Principles For Software Inventions, Umakant Mishra

Umakant Mishra

Applying 40 Principles is one of the earliest and most popular techniques of TRIZ. There are no controversies on application of 40 principles by any of the TRIZ schools. Although they are fundamentally sound, there is some difficulty in applying those in software related problems. As they were originally developed for mechanical or technical problems, the meaning of many terms like 'thermal', 'aerodynamic', 'hydrodynamic', 'ultrasonic', 'infrared', 'temperature', 'liquid', 'gas' etc. are embarrassing in a software context.

This article reviews the 40 principles in the context of software industry and rephrases the principles and their applications to make them suitable for …

Lightweight Directory Access Protocol (LDAP) is an IETF open standard to provide directory services in the network. LDAP is based on X.500 directory architecture, intended to provide directory services in Internet compatible environments. LDAP is used to provide directory services to applications ranging from e-mail systems to distributed system management tools. LDAP is becoming more and more popular with its wider usage in the Internet.

This report on LDAP is based on a study of 60 selected patents on LDAP from US patent database. The objective of this article is to present the distribution of patents according to different features …

Evolution Of User Interfaces For The Visually Impaired- Part 2, 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.

This article analyses the types of visual disabilities, different assistive technologies for different visual disabilities, guidelines for developing user interfaces for the visually impaired, software products available for …

Can A Triz Software Help You Inventing?, Umakant Mishra

Umakant Mishra

A software on TRIZ and/or Innovation can certainly supplement human brain and memory in order to speed up an innovation job. There are various TRIZ and Innovation software available in market. Some are too complex to use, some deal with only limited number of TRIZ techniques and some are having good features of innovation without much emphasis on TRIZ. An obvious task remains to evaluate them and find which software can help you best in inventing.

This article does not recommend or reject any TRIZ software per se. It only describes the expected features of a good TRIZ software and …

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 …
