Abstract
When thinking of users, it is possible to look at them from a variety of perspectives. One
essential way of considering users within the human–technology environment involves technical
concepts. In this manner, we define what users should be able to do with a particular technical
system. As such, there are tasks to accomplish and goals to reach by means of some technology,
and therefore specific operations must be carried out in order to reach those goals or fulfill those
tasks. For example, if someone wishes to buy boots from an eShop, it is necessary to get onto
the Internet, find the eShop, find the boots, load them into a virtual shopping cart, and follow the
process to check out. Savvy online shoppers can do this quite effortlessly.
