Importance And Aspects Of Human Computer Interaction ( HCI )

The Accessibility for Ontarians with Disabilities Act (AODA) assists Ontarians by “developing, implementing and enforcing accessibility standards in order to achieve accessibility for Ontarians with disabilities…”. This act creates a standard that must be met through all facets of society. Whether it be in an in-store customer experience, in the workplace or online, AODA lays a framework that will assist in the day-to-day lives of Ontarians with disabilities. This act greatly impacts the IT field, in that it changes the way IT professionals utilize technology, in order to assist and accommodate disabled citizens. Disabled Ontarians occupy a significant population within all of Ontario, “15.5% of Ontario’s population has a disability and this

When humans want change, they are able to do it on their own. If they want get something to eat, they can get up and walk to the refrigerator and get something to eat. If they need to take notes, they are able to use their hands and write down what they wish. The output devises needed by a computer such as monitor, keyboard,

Usability is a critical portion of web design that one must be ever mindful of when constructing websites. Whether creating a personal web space or building multiple pages for a large corporation, it is the burden of the designer to guarantee people can access that content. According to the United Nations, disabled people compose roughly 10 percent of the world’s population (United Nations, 2010). Many regulations and standards have been set forth to provide disabled people with the same opportunities to access content available on the World Wide Web, as it is most of the World’s population.

The effectiveness of HCI can also be measured by doing tests on that HCI to see how much errors it has, and after doing tests if the results show that it has a lot of errors then that HCI will not be a very effective. This is because a lot of errors on a HCI can make the user slow down when interacting with the HCI, but if there are not that much errors then it can be known as an effective HCI, because the user can use it effectively without having to troubleshoot.

In this article Car referenced many sources, one of which includes the University College London, who conducted a five-year research program, that examined computer

The excessive use of computers has drastically changed the lives of many users. As a multifaceted tool, the computer is used for tasks to include research, homework, business related

Today, computers are found everywhere and people rely upon them for travel directions, entertainment, purchasing products, and social interactions.

Input operation is external instructions that are put into computer data form. Two examples of Input would be a video camera and the videos another would be a keyboard and the characters that are used.

It’s the 21st century and the world is experiencing an all time high in innovations in technology. These innovations in technology have helped the world break many communication barriers. Cellular phones make it easy to call anyone around the world with the press of a few buttons. Webcams and computers are used to help one video chat and send emails all in the matter of a few minuets. Due to these innovations many people with disabilities find it easier to communicate as well. This new technology has led to a greater acceptance and inclusion of people with disabilities in society. For example, deaf people can use Facetime to call each other and sign through there. There also have been many applications developed for our hand held devices to

According to the Australian Department of Social Services (2012), web accessibility is not just about making sure websites are usable for those with disabilities’; it is about making sure that a website can be used by as many people as is possible. This could include making sure websites are accessible for people on a variety of different devices, those with impaired abilities, the elderly, and people from a different cultural backgrounds who may struggle with the native language (W3C, 2005). Websites that are designed to be accessible are generally much more usable for everyone, not just those who may need certain accessibility features (Riley-Huff, 2012). It is important that websites are as accessible as possible not only to allow them

Pryor to undertaking this activity I did not understand the basic skills required in order to make computer use easier. In the past I completed computer task based off of head knowledge and at times I would find myself completing my assignments in long periods of time. Though technology has improved I have become comfortable with old technology and have not tried to explore current updates until now. When presented with the opportunity to update my computer I would often not take advantage of the opportunity. This assignment allowed me to have a hands on experience that assisted me in learning the basic use of a computer.

Generally, there are two key forms of monitor interfaces that should be highly considered in the process of designing different computer applications namely the multi-touch screen interface and the mouse-driven interface. The controlling actions that are carried out by different computer users tend to have different preferences when it comes to the use of different computer applications uses (Dearden, 2008). As such, the application of the multi-touch screen gives computer users an opportunity to interact with the computer applications via a touch screen that will give them a chance to tap, swipe, long tap, and pinch the screens for purposes of performing their required

Individuals with sight problems can adjust color and brightness to assist them in viewing programs. Children with hearing problems can adjust volume controls and replace noise commands with visual commands. For example, if a child clicks on a program that is unable to open, they can program the computer to respond with a verbal message informing them of the inaccessible program, as opposed to the usual noise response. “Laptop computers can provide high-tech tools for note taking because of their mobility”(Barfield, 2003, p. 1). Customized computers also offer many different options for individuals depending on their needs. Touch screens, and touch pads enable an individual to use a computer by simply touching a screen or pad with his/her finger. “This often allows students who have fine motor problems, inaccurate keyboard skills, or problems with spelling to complete programs without frustration (Olson, 2000, p. 344). Voice activated computers allow students to use a microphone to enter information into the computer. Positions of buttons and switches can also be changed to accommodate an individuals certain needs. Other parts of the computer can also be altered to aid an individual with special needs. For example, individuals with limited motor control often use a key guard. “A keyguard is a keyboard overlay with holes positioned over each key. This assists in stabilization of finger, hand, or stick movement (Ray, 1995, p.

On the other hand, computers are one of the technologies that changed greatly over time the most. they can make our work easier, well-organized and more convenient than using the old ways of writing and computing files. From bulky computers with CPU, keyboards and mouse, have changed into portable laptops and net book which help us access Internet immediately. Computers are also becoming touch screens. More like tablets today. We better take note that we don’t have to use our mouse or keyboard because they are operated with just a touch of our hand. It feels like we are writing in our notepad, yet so easy.

Businesses rely heavily on knowledge about human-machine interaction (HMI) in the successful use of existing and new products. This work will examine IBM research as well as three other sites involved with Human-Computer Interaction (HCI) and the approaches utilized in comparison to IBM.
