The issue of website usability has garnered much attention today. In fact, there have been laws and legal moves against website developers who wouldnt take into consideration the wide range of people who will be viewing their websites.
The issue of usability has been founded on the context that there are a lot of people who are disabled or impaired in some way. In America alone, there are 1 out of 5 people who are disabled in one way or another.
The Internet has provided us with ways to communicate, interact, exchange information and do business. It is a pertinent tool in providing much needed avenues for accessing these things especially for people who are disabled. This is why usability has been a pressing issue in terms of website development.
Frames and website usability
One of the ways which can increase the usability of a website is the proper use of frames. Frames basically segment the browser into different portion and each portion is independent from the others. There are two major schools of thought when it comes to the use of frames: one that says frames should not be used and one that says that there are advantages to using frames in website development.
This article tries to give guidance on the use of frames in website development. The ultimate aim of website development is to make it easier for more people to use the website, whether with the use of frames or without them.
Why not use frames?
There are a lot of negative thoughts when it comes to the use of frames in websites. Here are some of them:
There have been much complaints about printing web pages that are framed. Internet browsers seem to select the frame to be sent to the printer randomly. The user cannot usually print the frame that he wants because the computer selects the frame which is the focal point of the webpage.
Many newbies in the field of website development employs frames to be able to cut the downloading time of their websites. This can only be achieved if the right ways of presenting the content are achieved. Other contents such as style sheets, images and scripts are recommended to be cached.
Using frames which contains third-party information can raise issues of infringement of copyrights and trademarks.
Visitors usually cannot mark the particular frame that he wants when using framed websites. The basic structure of frames deviates from the normal structure of unification of the website. This can cause problems in bookmarking.
Search engines encounter problems when indexing framed sites. This is a result of the frames paradox. The spiders of the search engines are drawn to what developers refer to as black hole pages.
Surfers may become confused with the structuring of a website which uses frames. The provision of multiple scrollbars will definitely add to the problem. If a designer hides the scrollbars, the contents of the website may become inaccessible.
Advantages in Using Frames
There are also some key advantages in using frames. Many people are still lured to use frames in their websites and listed below are some of the explanations why they are inclined to do so:
Ease in designing
One of the key features of the usage of frames in websites is that it makes the job easier for the developer. When a developer employs frames, he is relieved of the task of putting the logos and navigation menu on every single page that he will develop. Frames can contain these information and need not to be copied every time a user clicks another page of the site.
Frames provide a surfer several mini-browsers which he can view all at the same time. This allows for more flexibility in terms of getting more work done or getting more information for a single viewing of the webpage.
With the use of frames, different site contents need not be downloaded every time a click is made. This makes downloading much easier because contents that should be re-downloaded need not be downloaded because they are contained in a different frame.
These are just some of the features and perceived disadvantages of the use of frames. They can be used as long as the developer knows how to fully maximize the potential of frames without making them a problem for the surfers.
There are many factors that affect the usability of a web site. To make sites noticeable to users, site owners must make use of attractive design and functional content. The usage of fonts is one of the factors that can draw or veer away visitors to a web site. Good fonts are important because it has an effect on how fast users can read whatever content that is present on the computer screen.
Fonts are utilized to make the majority of the web page elements, such as navigation bars, buttons, links, and menus. It is the text that will express most of the web site’s content.
At present, the fonts that are commonly used in the Internet are Times New Roman, a serif font, and the Arial, a sans serif font. The primary edge of serif fonts is that it is more comfortable to read it on paper, because serifs help individualize each letter. However, this advantage can be rendered useless when the fonts are viewed on computer screens, since factors such as screen resolution can affect the clarity of texts.
So how do fonts influence the overall usability and legibility of a web site?
There are two major categories of font faces:
These are fonts that contain small appendages in the upper and lower part of a letter. Examples are Times New Roman, Century, Bookman and Courier. These are the choice faces to be used for large quantities of text.
These fonts have only primary line strokes, and possess a simpler shape. Examples of these fonts are Futura, Helvetica, and Arial. They are usually utilized for short phrases.
Font style pertains to the usage of elements such as italics, underlining, and boldfaces to give better emphasis to the contents of a page. It is not advised to utilize underlining on web pages, since most of the users are used to associate underlinings with links. Boldfaces should be used in a strategic way. Too much usage of boldfaces can be distracting from the content, since they are extremely visible. Since italics are not very legible on the screen, they should be used infrequently, just enough to provide emphasis and definition to terms.
Avoid using absolute font sizes. Doing so may hinder users the ability to adjust the sizes of the text to go along with the specifics of display devices that they are using. It is recommended to let users manipulate the size of the texts, especially if one plans to keep the web pages short.
Choosing font colors should be done with care, it should maximize the legibility of the text in contrast to the background of the page while setting it apart from colors used for links. For light backgrounds, one should used fonts in black, dark green, dark brown, and dark blue. If the background is dark, fonts in white, pale green, and pale orange should be used. If possible, use only one or two font colors in a page, excluding the colors for the link pages.
There are images that look like fonts. Avoid using them. There are several reasons why one should not utilize .jpg or .gif images to acquire special effects. First, images takes a long time to download, and when it appears, the quality is not the same as the text produced by the by browsers. Second, there usually is a problem when resizing images. Third, these images cannot be recognized by voice-enabled browsers.
It is said that Sans serif fonts should be used for standard and top-of-the-line web site designs, specifically the Arial and the Verdana. It is recommended to use the same font throughout a page, but headline sizes can be added and the subheadings can be written in bold form to prevent monotony. Again, it is preferable to give users the ability to control the size of the texts, since some of the users can be visually-challenged.
Some studies show that fonts that are tinier than 10-point gets slower reaction from users. It is advisable to use fonts that are at least 12 or 14-point in size when it comes to people over the age of 65.
A website that promotes appetite suppressant would look good with that.
The quality of a well-designed web site is that it can be accessed and used by people from all walks of life. Web sites should be designed to suit everyone who will be able to visit them.
March 27Website Accessibility and Usability
Usability is one of the most pressing issues in the field of website development nowadays. The usability of a website is tested against its simplicity which makes it easy for people to navigate the site as fast as possible, therefore making access to information easier.
Accessibility is a concept that is intertwined with the concept of usability. It refers to creating the website content available to all people.
The issue has caught the attention of different sectors of society. Why? Because 1 out of 5 people in America possess some kind of disability and this figure translates to around 30 million Americans. The figure is still increasing, with the coming of age of senior citizens. During the past decade alone, a dramatic increase of 25% was seen.
Why the Internet?
One might ask, Why is the Internet a central focus in this issue of usability? The Internet has transformed the lives of people during the past decade. People have been able to do things that they were not able to do before, this includes the people with disabilities. People who are impaired dont have as much opportunities compared to people who are well and able. The Internet has provided them avenues for communication, information gathering, social interaction, engaging in cultural activities and it provides them with employment opportunities. However, statistics have shown that the potential of the Internet to provide these certain opportunities is still not maximized because the people with disabilities are hindered by usability issues from using it to the fullest.
The issue of usability is not only watched by institutions which are related to giving support to people with disabilities, most of the sectors of society are closely watching its progress. Institutions which are involved in governance, education, media, public services and even the business sectors are observers in the game.
The benefits of improving accessibility of websites will not only benefit the people who have impairments but will affect the whole web community. Businesses, services, information campaigners, everyone will benefit.
Many people are calling for developing websites using a universal design approach. This is a way of developing web content which would accommodate the widest range of users. Some features of this said scheme are: provision of inter-operability of applications; access for the disabled; localization and customization.
Recommendations for Improving Accessibility
Listed below are some of the key recommendations from the Web Content Accessibility Guidelines 1.0 which was developed by the Web Accessibility Initiative of W3C on how to improve the accessibility of the contents of a website.
1. Provide alternatives to audio-visual content
Not all people will be able to use different kinds of content. These people may be disabled or may have a lower version of Internet browsers. Movies, sound clips, animations and other contents should be translated into text alternatives so as to provide information to the broadest range of viewers.
2. Developers shouldnt rely on color alone
Many people are impaired in color differentiation. Developers shouldnt rely too much on the use of colors to relay information in the websites. Charts that are color-coded should be modified and the background and foreground colors of the websites should have enough contrast to enable people with color differentiation impairment to easily navigate the site.
3. Clarification of the use of natural language
Content developers usually mark up the changes in natural language in their websites. They should be able to identify the dominant language that is used in the site so as to avoid confusion.
4. Control of content changes that are time-sensitive
This issue particularly involves people who have visual or cognitive impairments and those who are not able to read texts that are moving quickly. Movement is seen as an over-all enhancer to the look of the site, but it may pose some problems to people with cognitive impairments.
5. Accessibility of user interfaces that are embedded
Objects that posses their own interfaces should be made accessible, and alternative solutions must be provided if this is not possible.
6. Provision of orientation and context information
The provision of information on how the objects are organized is important to provide people with guidance on how to access information.
There are other ways of improving a websites over-all accessibility to make it more usable. Developers should take into consideration the different people who are going to view their websites and make them focal points in the designing process.
When looking for a new watch to purchase, dependability is an important factor. Oftentimes, a person will buy an affordable watch and find that it only works for a short amount of time. For a watch that is stylish and dependable, and has had an interesting impact on the history of watches, one should look into purchasing a Breitling watch.
About the Breitling Brand
Breitling watches are Swiss-made, and specifically originate from the Canton of Jura in Switzerland. Although they were originally designed as aviation watches, Breitling watches have become more of a status symbol, with movie stars such as John Travolta and Jerry Seinfeld frequently wearing Breitling watches.
During World War II, The Germans introduced faucets.
The idea for Breitling watches originated in 1884 when a man named Leon Breitling opened a workshop for making precision counters and chronographs. Chronographs, or chronometers, are ways for measuring time precisely, and are still implemented in Breitling watches today.
By 1892, Leon Breitling’s company had grown to such an extent that he had to relocate from his original rural location in the Canton of Jura, to La Chaux-de-Fonds. La Chaux-de-fonds was, at the time, considered the very center of watch making in Switzerland.
Leon Breitling continued to prosper with his company until his death in 1914, at which time the company was taken over by his son Gaston. In 1915, Gaston, using chronograph technology, created the first wristwatch. This creation subsequently provided pilots with first wrist instruments in aviation thanks to this technology.
In 1923, a new type of Breitling watch was introduced, which was an independent chronograph push piece. Before the invention of this watch, the winding crown of watches controlled the start and return-to-zero functions.
Breitling watches continued to be improved over the years, implementing both style and advanced aeronautical technology into their watches. For example, in 1952, the Navitimer was introduced, which included the ability to measure short periods of time and airborne calculations such as climbing times. This watch could also convert miles into kilometers or nautical miles.
Today, Breitling watches continue to develop in terms of excellent aeronautical technology. As such, these watches are quite expensive and will cost at least a thousand dollars. These watches can be found in several places throughout the world, thus the best way to find a nearby location is to search the internet. Indeed, for efficiency and style, a Breitling watch is an excellent choice whether one is a pilot or not.
