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 …

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 Expressing Emotions In Graphical User Interface, Umakant Mishra

Umakant Mishra

The conventional GUI is more mechanical and does not recognize or communicate emotions. The modern GUIs are trying to infer the likely emotional state and personality of the user and communicate through a corresponding emotional state. Emotions are expressed in graphical icons, sounds, pictures and other means. The emotions are found to be useful in especially in communication software, interactive learning systems, robotics and other adaptive environments. Various mechanisms have been developed to express emotions through graphical user interfaces. This article illustrates some interesting inventions selected from US patent database.
