Las barras de mosaico (TileBars) son una técnica de visualización de búsquedas en documentos que permiten hacerse una idea más clara de lo que nos devuelve un buscador, añadiendo la serendipia (descubrimiento accidental) al concepto de relevancia.
The arrow and its brethren are everywhere on our computer screens. For example, a quick examination of the Firefox 3.0 browser, shown in Figure 1 in its standard configuration, yields eight examples of arrows—Forward, Back, and Reload buttons, scroll bar controls, and drop-down menus that reveal search engine, history, and bookmark choices.
Interface design is difficult in part because everything requires interpretation. A design that works for one task or one user might not be appropriate for another. In other types of engineering, like architecture or bridge building, designers can always rely on laws of physics and gravity to make designs work. There is at least one immutable rule for interface design that we know about, and it's called Fitts's Law. It can be applied to software interfaces as well as Web site design because it involves the way people interact with mouse or other pointing devices. Most GUI platforms have built-in common controls designed with Fitts's Law in mind. Many Web designers, however, have yet to recognize the powerful little facts that make this concept so useful.
Human Factors is often used interchangeably with User Interface Design or Human-Computer Interface. There is a lot of overlap in these disciplines; however, Human Factors generally refers to hardware design while HCI generally refers to software design.
This section provides a theoretical base for the wealth of practical information on implementing the Aqua interface elements presented in the rest of this book. You’ll undoubtedly find that you can’t design in accordance with all of the principles all the time. In those situations, you’ll have to make decisions based on which principle or set of principles is most important in the context of the task you’re solving. User testing is often an excellent way to decide between conflicting principles in a particular context.
This document describes the additions and changes to Macintosh Human Interface Guidelines related to the release of Mac OS 8. Specifically, it presents guidelines for taking advantage of the Mac OS platinum appearance and the Appearance Manager. This document does not replace Macintosh Human Interface Guidelines.
This document, which covers features up to Mac OS X version 10.2, describes what you need to do to design your application for Aqua. Primarily intended for Carbon and Cocoa developers who want their applications to look right and behave correctly in Mac OS X, these guidelines provide examples of how to use Aqua interface elements. Java application developers will also find these guidelines useful.
I recently conducted a study into the helpfulness (or lack thereof) of zebra striping—the shading of alternate rows in a table or form. The study measured performance as users completed a series of tasks and found no statistically significant improvement in accuracy—and very little statistically significant improvement in speed when zebra stripes were implemented.
