In considering access to the Internet through devices located in places accessible to the public, we have to distinguish between focused access and unlimited access.
Examples are kiosks which provide information for tourists or opportunities for job seekers.
We generally consider the requirements of these two types as quite different. For example, we make the focused access type rugged so that we can leave it unattended. Hence touch screen commands are very popular. On the other hand, for unlimited access, the device is simply a conventional PC with a keyboard and a mouse. Not surprisingly, we have to place these in securer environments where they will not suffer vandalism or disappear.
