Accessibility of the Technology | Refers to the degree to which all people can access the Internet using whichever device they prefer (e.g., computer, laptop, tablet, or mobile phone) regardless of available dial-up/high-speed, Wi-Fi, or mobile phone Internet service. Dissemination strategies to maximize technology accessibility include providing both text-heavy and graphics-heavy versions of a PtDA, as well as versions for multiple screen sizes and mobile phones (known as responsive design). |
Universality of the Technology | Refers to the degree to which the PtDA is accessible for men and women of all ages, races, ethnicities, religions, languages, and cultures. |
Usability of the Technology | “…refers to how well users can learn and use a product to achieve their goals and how satisfied they are with that process” (ISO/AWI TR 9241-11, 1998) [43]. This definition includes a combination of factors, primarily focusing on five areas: 1. Ease of Learning - How easy it is to do basic tasks the first time you see the website, 2. Efficiency of Use - How quickly you can use the website once you know how, 3. Memorability - How well you can remember how to use it the next time you visit, 4. Error Frequency - How many errors are typically made in looking for information, and 5. Satisfaction - How much you like using the website. |
