Maximising Your Navigational Tool

Usabilityis an important word for Web designers. It means just what it says making a site usable. Without usability, nothing else you do matters. What good is it to have wonderful content if nobody can find it? What good is it to have beautiful graphics on a page that is inaccessible except by luck? Fortunately, designing a usable Web site isn't difficult, and a few simple rules set you on your way. As with any set of rules, you may want to break these from time to time, but by doing so can cause problems: 

Keep your navigation system consistent on all the pages in your Website.

If you have a link to your home page at the top of half your pagesand put the same link at the bottom of the rest of the pages, you may confuse your visitors. 

Put links to your home page and your search function on both the top and bottom of every page. Too many Web designers put them on onlythe top or the bottom, forcing users to scroll to find them. Don't makeyour visitors do extra work. Putting them on both the top and bottom of the page elevates this problem. 

Never use blue, underlined text for anything but a link.

It's better to try to avoid underlining at all. Use bold or italics for emphasis instead, otherwise, you may fool a lot of people into clicking that text to no effect. 

Don't use too many links in a navigation bar.

Half a dozen is about the most you should add. Remember that a navigation bar is not a site map but a guide to the major pages within your site. 

Use words.

Using graphical icons may make your pages prettier, but you should design your navigation bar (or whatever alternative you use) to instantly communicate what it means to someone who hasn't visited your site before. In this case, a picture is not worth a thousand words. 

If your site is composed of hierarchical pages (and most of them are), consider using breadcrumb navigation.

The term comes from theidea of leaving a trail of breadcrumbs as you walk so that you can easilyretrace your steps. When applied to a Web site, the metaphor refers to alisting at the top of the page showing the current page's relationship tothe hierarchy. 

Adding a Search Function 

Unless your site consists of just a single Web page, you need a search engine for it. Sites that don't offer search functions are at a real disadvantage compared with those that do have them. Put yourself in a visitor's shoes and ask, "Do I want to spend hours browsing this site in the hope that I may stumble across the information I want? Or do I want to spend a few seconds running a search to get the information I need right away?" Search engines are by far the best way for visitors to find the information they require on your website. 

All of the search options which are available to use on your website, have their own strengths and weaknesses. The importance of each feature is a matter for you to decide. I recommend checking out as many as you can. Because none of them requires much effort to install and use, you may as well road-test a few to see which you like best.

Navigation $49.99 Navigation - Giclee Print

Wilderness Navigation Handbook $9.99 Designed for both land and water use, this comprehensive guide helps unlock the complexity of map and chart reading as it relates to navigation. Beginning with detailed technical descriptions of the tools of navigation—a compass, an altimeter, a GPS system, and a sextant—this handbook shows how to use these tools either individually or in combination with each other to navigate any area. Factors that cause tools and techniques to fail are discussed, such as why an altimeter often shows the wrong elevation, a GPS position is sometimes off track, and the sun often points in an unexpected direction. Twenty-one real-life scenarios provide practical wisdom for even the most intrepid navigator. Specific information on using the moon for directions and the stars for position, measuring boiling water temperature for elevation, map projections, map datums, great circle routes, and the UTM/UPS grid system is included.

Cartographies of Travel and Navigation $48 Finding one’s way with a map is a relatively recent phenomenon. In premodern times, maps were used, if at all, mainly for planning journeys in advance, not for guiding travelers on the road. With the exception of navigational sea charts, the use of maps by travelers only became common in the modern era; indeed, in the last two hundred years, maps have become the most ubiquitous and familiar genre of modern cartography. Examining the historical relationship between travelers, navigation, and maps, Cartographies of Travel and Navigation considers the cartographic response to the new modalities of modern travel brought about by technological and institutional developments in the twentieth century. Highlighting the ways in which the travelers, operators, and planners of modern transportation systems value maps as both navigation tools and as representatives of a radical new mobility, this collection brings the cartography of travel—by road, sea, rail, and air—to the forefront, placing maps at the center of the history of travel and movement. Richly and colorfully illustrated, Cartographies of Travel and Navigation ably fills the void in historical literature on transportation mapping.

Captain Jack's Celestial Navigation $21.51 Captain Jack I. Davis has done it again He has written yet another, very easy to understand, instructional navigation book. As in his first book, Captain Jack's Basic Navigation, this book is filled with knowledge, new sea stories, and more humorous anecdotes. Using the same highly successful format of his first book, Captain Jack takes the reader through each phase of navigation by first explaining, in detail, the steps needed to complete each phase. This is followed by a list of questions to answer, using your new-found knowledge. After you have completed the questions, you can check your answers at the end of each chapter. All the calculations are accomplished with simple, grade school math using an inexpensive calculator and basic plotting tools. If you believe you do not need these Old Time navigational skills in this modern age of electronic navigation, Captain Jack restates his suggestion to you: "Tape a mirror below your GPS display. When the electronics fail, you can look in the mirror and see exactly who is lost."

Risk Navigation Strategies for Major Capital Projects $129 Risk Navigation Strategies for Major Capital Projects provides a fresh look at planning, controlling, managing and leading major projects in an international setting. It is not a critique against the project management profession and the current state of art in project management tools. It simply addresses the fact that, no matter how well we manage projects and how mature the project management organization is, overruns and significant deviations still occur. The authors reflect on the reasons for this and give a framework for how the current project management culture can be influenced in the direction of better performance and compliance with the business objectives of the project. Risk Navigation Strategies for Major Capital Projects is intended for executives who invest in major projects or who are responsible for managing and leading such projects. Developers of project management approaches in the industry may also find the book interesting, as well as consultants and researchers in the field.

Directed Sonar Sensing for Mobile Robot Navigation $237.38 While many mobile robots come equipped with ultrasonic range sensing (sonar), accurate map building and position estimation using sonar has been elusive, because of the difficulty in interpreting sonar data correctly. This book presents evidence that sonar can in fact fulfill the perception role for the provision of longterm autonomous navigation in a broad class of manmade environments. A new approach to mobile robot navigation is presented that unifies the problems of localization, obstacle detection, and map building in a combined multitarget tracking framework. The primary tools of this approach are the Kalman filter and a physically based sonar sensor model. Experimental results with real sonar data demonstrate modelbased localization using an a priori handmeasured map and subcentimeter accuracy map building for an uncluttered office scene. This book will be of particular interest to researchers in mobile robotics, especially potential users of sonar. The approach has greater significance, however, as the issues involved the choice of representation, the problem of data association, and the pursuit of longterm autonomy are central to many outstanding problems in robotics and artificial intelligence.
