Until the 1980s, using a computer program meant memorizing a lot of commands and typing them in a line at a time, only to get lines of text back. The graphical user interface, or GUI, changed that. By representing programs, program functions, and data as two-dimensional images — like icons, buttons and windows — the GUI made intuitive and spatial what had been memory intensive and laborious.

But while the GUI made things easier for computer users, it didn’t make them any easier for computer programmers. Underlying GUI components is a lot of computer code, and usually, building or customizing a program, or getting different programs to work together, still means manipulating that code. Researchers in MIT’s Computer Science and Artificial Intelligence Lab hope to change that, with a system that allows people to write programs using screen shots of GUIs. Ultimately, the system could allow casual computer users to create their own programs without having to master a programming language.

Two decades ago, Web usage was limited to a single individual (Sir Tim Berners-Lee) using the only browser in existence (WorldWideWeb) running on a single platform (a NeXT Computer). Nowadays, billions of people access the Web daily, with the ability to choose from over a dozen browsers running on desktop computers, laptops, and a variety of mobile devices, such as cell phones. The number of possible combinations is growing rapidly, and makes it increasingly difficult for Web designers and developers to craft their sites so as to be universally accessible. This is particularly true when accounting for Web users with physical and cognitive disabilities — especially if they do not have access to assistive technologies. The challenges and solutions for anyone creating an accessible website are addressed in Universal Design for Web Applications, authored by Wendy Chisholm and Matt May.

Finally, we are learning that simplicity equals sanity. We’re rebelling against technology that’s too complicated, DVD players with too many menus, and software accompanied by 75-megabyte “read me” manuals. The iPod’s clean gadgetry has made simplicity hip. But sometimes we find ourselves caught up in the simplicity paradox: we want something that’s simple and easy to use, but also does all the complex things we might ever want it to do. In The Laws of Simplicity, John Maeda offers ten laws for balancing simplicity and complexity in business, technology, and design—guidelines for needing less and actually getting more.

As the name suggests, GUIs (Graphical User Interfaces) present their features and functions visually. The human-computer interaction is heavily based on seeing things, looking for things and interacting with graphical UI elements. Color is a main characteristic of any visual scene, not only on computer screens, but in any situation where we see something. Because most of what we see and interact with in our everyday life is colored (as opposed to shades of white-gray-black), we are very familiar with colors – maybe so much that we don’t think about them a lot. On the other hand, it does bother us when we need to read a dark-gray label on a black button. So colors have the potential to boost or wreck the user experience. This article will introduce the concept of user experience and highlight some aspects of colors and color perception together with recommendations for UI design.
