The Components of Usability

The ease of use of the Web includes small learning curves, easy content search and search ease, task efficiency, satisfaction, and automation. A new component of these availability comes from the development of Web and devices. Example: Automation: automatic input, database, personal account, efficiency: voice commands (siri, alexa, ... etc); findabiltiy: the number of sites reached 4 billion, usability got better, Content Now Available Content With the spread of mobile devices and wireless Internet access, enterprises can enter the world market through users in different countries. You can use the website regardless of the user's language or culture. Most users are doing personal business online. Bank opening, learning, errands etc. This provides a great opportunity for people with disabilities to become independent. Therefore, these users must be able to access the website.

Reusability is an important function of high quality software components. Programmers need to design and implement software components so that various programs can reuse them. In addition, if the software component interacts directly with the user, it is necessary to consider component-based usability testing. In the 1960s, programmers built a library of scientific subroutines. It can be reused in various engineering and scientific applications. These subroutines reuse well-defined algorithms in an efficient way, but their scope is limited. Commercial sites typically use reusable modules written in assembly language, COBOL, PL / 1, and other second and third generation languages ​​using system and user application libraries to create applications To do.

Brief introduction of accessibility functions is important for widely adopted in Shopify. One approach is a reusable schema library built with our UX team, including component code used in our application. It is an obvious starting point to make sure that these components are accessible. In the UI library, elements such as form fields have standard tags in all parts of Admin, and developers use APIs for applications. In this example, the developer can pass the form field and the recommended help text, and the component will use the correct HTML and ARIA properties to fire out the appropriate input, tag, and help text. The helper generates accessible tags, but because the original tags are in a single file that can be reused, it also provides an easy way to update and fix the error. For example, if you find a use case with a more complex error condition, you can update the helper's markup and improve the application as a whole.
