Zusammenfassung
Direct manipulation claims to offer a number of advantages. In practice, however,
direct manipulation is not used very often, even graphics programms are controlled
mostly by means of conventional menu techniques.
Nature and range of direct manipulation are debatable and seem quite changeable.
Often direct manipulation is reduced to a picture show. Restrictions like the number
of supplied movements or actions and paradoxies such as the contradiction between
realism and abstraction upon the design of pictograms are important reasons why
direct manipulation is restricted to some parts of operating systems and application
programs. The different communication capacity of pictures and text (menus, commands)
is important too. New ideas like video interfaces with voice input and output
as essential components point to a stagnant or even reduced importance of direct
manipulation.
