Early computer systems relied on command line interfaces to perform all actions. Today, the majority of systems use direct
manipulation rather than a command line interface. The goal of designing a direct manipulation interface is to make use of
the system intuitive to the end user. One industry that has been extremely successful designing intuitive direct
manipulation inputs is the video game industry. Most game players are abie to learn controls as they play a game and
then apply the same controls to similar games. Rarely do they need to read a user manual.
Write a paper in which you:
1.Describe the three (3) principtes of direct manipulation and give examples as to how they are used in video game
controls…
2.Analyze video game-iype interfaces and discuss three (3) reasons why video game-type interfaces would not be
effective for real-worid applications..
3.Describe at teast three (3) advantages of direct manipulation versus command line interfaces..
4.Evaluate direct manipulation and describe three (3) problems with it..
