Natural User Interface

In computing, a Natural User Interface (NUI) is the common parlance used by designers and developers of human-machine interfaces to refer to a user interface that is effectively invisible, and remains invisible as the user continuously learns increasingly complex interactions. The word natural is used because most computer interfaces use artificial control devices whose operation has to be learned.

Graphical user interface

In computing, a graphical user interface (GUI, sometimes pronounced “gooey” or “gee-you-eye”) is a type of interface that allows users to interact with electronic devices through graphical icons and visual indicators such as secondary notation, as opposed to text-based interfaces, typed command labels or text navigation. GUIs were introduced in reaction to the perceived steep learning curve of command-line interfaces (CLIs), which require commands to be typed on the keyboard.

Parallax scrolling

Parallax scrolling is a special scrolling technique in computer graphics, wherein background images move by the camera slower than foreground images, creating an illusion of depth in a 2D video game and adding to the immersion.
Web designers began incorporating parallax scrolling in 2011, using HTML5 and CSS3. Websites with parallax backgrounds are becoming an increasingly popular strategy, as advocates argue it is a simple way to embrace the fluidity of the Web.

WebGL

A Web Graphics Library (WebGL) is a JavaScript API for rendering interactive 3D computer graphics and 2D graphics within any compatible web browser without the use of plug-ins. WebGL is integrated completely into all the web standards of the browser allowing GPU accelerated usage of physics and image processing and effects as part of the web page canvas. WebGL elements can be mixed with other HTML elements and composited with other parts of the page or page background.

Twitterbot

A Twitterbot is a program used to produce automated posts on the Twitter microblogging service, or to automatically follow Twitter users. Twitterbots come in various forms. For example, many serve as spam, enticing clicks on promotional links. Others post @replies or automatically “retweet” in response to tweets that include a certain word or phrase. These automatic tweets are often seen as fun or silly. Some Twitter users even program Twitterbots to assist themselves with scheduling or reminders.

UEM

User experience moment.

Usability

Usability refers to how easy it is for a visitor to your site to use your site in its intended manner. In other words, are navigation, content, images, and any interactive elements easy to use, functioning the way they were intended, and that your intended target visitor will not need any special training in order to use your site.

Permalink

Short for “permanent link.” Generally used only on blogs, a permalink is a link that is the permanent web address of a given blog post. Since most blogs have constantly-changing content, the permalink offers a way for readers to bookmark or link to specific posts even after those posts have moved off the home page or primary category page.

Pageview

A pageview is a request for an entire web page document from a server by a visitor’s browser. In other words, for each page view your site had, someone (or a search engine spider) looked at that page.

Meta data

Meta data is the data contained in the header that offers information about the web page that a visitor is currently on. The information contained in the meta data isn’t viewable on the web page (except in the source code). Meta data is contained within meta tags.

Hypertext

Hypertext is any computer-based text that includes hyperlinks. Hypertext can also include presentation devices like tables or images, in addition to plain text and links.

Hyperlink

A hyperlink is a link from one web page to another, either on the same site or another one. Generally these are text or images, and are highlighted in some way (text is often underlined or put in a different color or font weight). The inclusion of hyperlinks are the “hyper” part of “hypertext.”

Hit

Contrary to popular belief, a hit does not represent a single visitor to a website. A hit is actually a request for a single file from your web server. This means one page can actually generate multiple hits, as each page generally has more than one file (an html or other base file, a css file, multiple images, etc.) and each one is requested from the server whenever the page is loaded. Some marketing people like to quote hits to unknowing consumers as the number makes their site sound like it’s getting a whole lot more traffic than it actually is.

Focal Point

The focal point of a web site is the spot on a web page that they eye is naturally drawn to. This could be an image, a banner, text, Flash content, or just about anything else. You want to make sure that whatever is acting as your focal point is the most important part of your site.

Fixed Width Layout

A fixed width layout has a set width (generally defined in pixels) set by the designer. The width stays the same regardless of screen resolution, monitor size, or browser window size. It allows for minute adjustments to be made to a design that will stay consistent across browsers. Designers have more control over exactly how a site will appear across platforms with this type of layout.

Elastic Layout

An elastic layout is one that uses percentages and ems for widths paired with a max-width style to allow the site layout to stretch when font sizes are changed. It’s ability to flex to accommodate the browser width and reader’s font preferences are where it gets its name.

Cascading Style Sheets

Also referred to simply as CSS, Cascading Style Sheets are used to define the look and feel of a web site outside of the actual HTML file(s) of the site. In recent years, CSS has replaced tables and other HTML-based methods for formatting and laying out websites. The benefits to using CSS are many, but some of the most important are the simplification of a site’s HTML files (which can actually increase search engine rankings) and the ability to completely change the style of a site by changing just one file, without having to make changes to content.

Cache/chaching

Cached files are those that are saved or copied (downloaded) by a web browser so that the next time that user visits the site, the page loads faster.

Bounce rate

A website’s bounce rate is the percentage of people who leave the site from the same page they entered the site, without clicking through to any other pages. This can be a good indicator of how good a website’s navigation is, as well as an indicator of the quality of the site’s content (a very high bounce rate doesn’t bode well for either of those things).

AJAX

Stands for Asynchronous JavaScript and XML. AJAX is typically used for creating dynamic web applications and allows for asynchronous data retrieval without having to reload the page a visitor is on. The JavaScript on a given page handles most of the basic functions of the application, making it perform more like a desktop program instead of a web-based one.
