Developing For Inclusion
Understanding Web Page Structure
A web page that is well structured with appropriate HTML markup will greatly improve assistive devices interoperability and keyboard navigation, which will ensure a good user experience and increased user productivity. People who use screen readers often cannot identify the navigation of a web site. Without visual context, these users sometimes cannot differentiate between sub-navigation and navigation elements. Most, screen reader users, when visiting a web page, expect website pages to be displayed in a consistent format. Global Trends and the Impact on Prosperity: David Best, AEBC Blog, February 2018
Screen reading technologies provide the user with many different ways to use a web page. Advanced screen reader users, when navigating through a site or finding specific information on a page, will likely use the screen reader features (keyboard shortcuts), rather than scanning through the content of the page starting at the beginning. However, most of these screen reader shortcuts, such as obtaining lists of links or headings depend to a large extent on the use of well structured code, which conforms to the Web Content Accessibility Guidelines. Less experienced screen reader users tend to read the web page sequentially, and thus depend upon a consistent content source order. The use of semantically correct and valid code, meaningful and appropriately marked up headings and descriptive link text will enable screen reader users to make the most effective use of their technologies when visiting a website.

Some Important Page Elements Are:
Using ARIA To Improve The User Experience
The Accessible Rich Internet Applications (ARIA) markup was designed to insert information useful to assistive technologies into existing HTML code. It exists as a way to label controls and to provide information about their states. Adding ARIA support to a Web page does not change the presentation or behavior of that Web page to sighted users. The browser plays a big role in interpreting ARIA markup. Most browsers support some type of accessibility API (application programming interface), and assistive technologies use the API to get information about what is presented on the screen. So, ARIA markup is transformed by the browser into information that fits the accessibility API it supports. Then, the information provided by the API is processed by the assistive technology. That means the assistive technology support of ARIA depends heavily on the browser being used. The assistive technology user agent gathers information from the ARIA markup and the browser's API and presents it in a meaningful way to the user. Because of the above interactions, the quality of the user agent support for ARIA markup is inextricably tied to the careful, thorough application of ARIA markup on a Web page, and comprehensive support provided by the browser in which the markup is rendered.
If you can use a native HTML element, or attribute with the semantics and behaviour you require already built in, instead of re-purposing an element and adding an ARIA role, state or property to make it accessible, then do so. If a non interactive element is used as the basis for an interactive element, developers have to add the semantics using ARIA and the appropriate interaction behaviour using scripting. In the case of a button, for example, it is much better and easier to just use a native HTML <button> instead of redefining an element with <span role=button>. All interactive widgets must be scripted to respond to standard key strokes or key stroke combinations where applicable. That is, if you create a widget that a user can click or tap or drag or drop or slide or scroll, a user must also be able to navigate to the widget and perform an equivalent action using the keyboard. Adding an ARIA role overrides the native role semantics in the accessibility tree which is reported via the accessibility API, and therefore ARIA indirectly affects what is reported to a screen reader or other assistive technology user agent. Adding an ARIA role will not make an element look or act differently for people not using assistive technology. It does not change the behaviours, states and properties of the host element but only the native role semantics.

User Interaction Design
A tool addresses human needs by amplifying human capabilities, and the human-tool interaction is designed to facilitate human-human communications. The goal is for the human-machine interface to become intuitive and an efficient human-human connection. That is, life activities should focus on real human habits and human needs, as opposed to focusing on the technology. Like the traffic signals communicate information for human safety behaviour, and the transmitter box in your car automatically connects with the toll booth on a highway. The role of technology design in human relationships is about effective communications in connecting human-human through machines.
Communication design deals with the delivery of messages, encompassing graphic design, wayfinding, and communicative objects of all kinds, from printed materials to three-dimensional and digital projects. Interface and interaction design delineate the behavior of products and systems as well as the experiences that people will have with them. Information and visualization design deal with the maps, diagrams, and tools that filter and make sense of information. The purpose of graphic design is to communicate a message; Be it advertising or be it signage. So that's design whose subject is communication.
It is pretty easy to get overwhelmed and frustrated by all the human-object interactions in the modern world. Whether openly and actively or in subtle, subliminal ways, things talk to us. Tangible and intangible, and at all scales; From the spoon to the city, the government, and the Web, and from buildings to communities, social networks, systems, and artificial worlds/things communicate. They do not all speak up: some use text, diagrams, visual interfaces, or even scent and temperature, while others just keep us company in eloquent silence. Thus far, 21st-century culture is centered on interaction with objects. However, the increasingly common
pictures under glass type of interface used on smart phones and tablets, limits the untapped potential of human capabilities. the evolution of communication design is all about the interface. That is, the interface must minimize the technology focus and maximize the human interactions and relationships.

Paola Antonelli, the Senior Curator in the Department of Architecture and Design at the Museum of Modern Art, most recent blockbuster show, Talk to Me, explored the communication between people and objects: from chairs that talk to subway kiosks. This fascinating show examined the future and the history of communication design.
Design for Seven Billion. Design for One: Microsoft, YouTube Learn how human-led design makes a deep and connecting impact, leading to innovative and inclusive solutions. Can design be both universal and personal? Embracing human diversity and Designing for inclusivity not only opens up products and experiences to more people with a wider range of abilities, it also reflects how people really are. All humans are growing, changing, and adapting to the world around them every day. Our solutions should reflect that diversity.
The PhET Interactive Simulations project at the University of Colorado Boulder creates free interactive math and science simulations. PhET sims are based on extensive education research and engage students through an intuitive, game-like environment where students learn through exploration and discovery. As users interact with these tools, they get immediate feedback about the effect of the changes they made. This allows them to investigate cause-and-effect relationships and answer scientific questions through exploration of the simulation. PhET is a free online physics, chemistry, biology, earth science and math simulations research project. Nobel Laureate Carl Wieman Founded PhET in 2002.

Designing Mindfulness is a manifesto from Mindfulness Everywhere. Mindfulness teaches us that the quality and nature of our attention has a direct impact on our wellbeing. Many of the interactions we have with technology every day involve our attention. Our wellbeing is therefore being affected by those attention-based products we use. Some companies simply do not understand the impact their products have on the minds of the people who use them. Other companies may deliberately use this knowledge to trap our attention and farm it for commercial gain. As a result, they have little care for the impact their products might have on the people who use them. how can we build the ideas and practices of mindfulness into technology so that the attention and wellbeing of the people who use it is best supported?
