He also provided a more practical definition of universal usability – "having more than 90% of all households as successful users of information and communications services at least once a week." The concept of universal usability ("usable by all") is closely related to the concepts of universal design and design for all.These three concepts altogether cover, from the user's end to the developer's end, the three important research areas of information and communications technology (ICT): use, access, and design.User analysis is a crucial aspect of user-centered systems design, yet Human-Computer Interaction (HCI) has yet to formulate reliable and valid characterisations of users beyond gross distinctions based on task and experience.Individual differences research from mainstream psychology has identified a stable set of characteristics that would appear to offer potential application in the HCI arena.When you click on a Sponsored Product ad, you will be taken to an Amazon detail page where you can learn more about the product and purchase it.To learn more about Amazon Sponsored Products, click here.Universal usability refers to the design of information and communications products and services that are usable for every citizen.The concept has been advocated by Professor Ben Shneiderman, a computer scientist at the Human-Computer Interaction Lab at the University of Maryland, College Park.
In the present paper the relationship between work in cognitive and differential psychology and current analyses of users in HCI is examined.To this end, design teams are urged to perform user and task analyses at the earliest stages of product development and to consider the nature of the users' cognitive and physical predispositions and abilities.These user characteristics are correctly seen as important in constraining the available design options and, if attended to, increasing the likelihood of producing a usable application.'Holding' and 'blending' in the computer age Holding via moblog.
