Modern buildings have ramps because architects take into account that some people will need to use wheelchairs. This is to ensure that all people can access the building. Ensuring that buildings are accessible is the norm, but when it comes to making software, we tend to not think of accessibility issues. There are two main ways that technology can be made more accessible: adaptable hardware and adaptable software.

Human computer interfaces are designed for people who have good vision and two hands (try typing with just one hand). There is hardware that is available that can make using a computer easier for people, although the cost of the equipment produces another form of the digital divide.

Modern buildings have ramps because architects take into account that some people will need to use wheelchairs. This is to ensure that all people can access the building. Ensuring that buildings are accessible is the norm, but when it comes to making software, we tend to not think of accessibility issues. There are two main ways that technology can be made more accessible: adaptable hardware and adaptable software.

Human computer interfaces are designed for people who have good vision and two hands (try typing with just one hand). There is hardware that is available that can make using a computer easier for people, although the cost of the equipment produces another form of the digital divide. People who have physical disabilities face many challenges when using a computer. For instance, if one cannot use a hand-operated mouse a foot-operated mouse is available, but at the price of a few hundred dollars.

It is easy to see that blind people have a hard time using a computer. Fortunately, there is software that can tell the computer user what is on the screen. The internet is one of the main reasons people use a computer, but the web is very visual. To overcome this hurdle screen readers are designed to read computer code that meets the standards set by the respected W3C organization. Some software can be operated by voice, currently only a few word processors and applications can be used by speaking to them though.

Universal design takes into consideration providing access for people regardless of the user’s circumstances. When it comes to hardware universal design is lacking, forcing people to purchase expensive hardware alternatives. Universal design for software is more common. When designing software, including websites, people should abide by standards to make it easier for people using adaptive technology to use.
