Assignment 3: Direct Manipulation



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 able 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 four to five (4-5) page paper in which you:
  1. Describe the three (3) principles of direct manipulation and give examples as to how they are used in video game controls.
  2. Analyze video game-type interfaces and discuss three (3) reasons why video game-type interfaces would not be effective for real-world applications.
  3. Describe at least three (3) advantages of direct manipulation versus command line interfaces.
  4. Evaluate direct manipulation and describe three (3) problems with it.
  5. Use at least three (3) quality resources in this assignment. Note: Wikipedia and similar Websites do not qualify as quality resources. 
Your assignment must follow these formatting requirements:
  • Be typed, double spaced, using Times New Roman font (size 12), with one-inch margins on all sides; citations and references must follow APA or school-specific format. Check with your professor for any additional instructions.
  • Include a cover page containing the title of the assignment, the student’s name, the professor’s name, the course title, and the date. The cover page and the reference page are not included in the required assignment page length. 
The specific course learning outcomes associated with this assignment are:
  • Describe direct manipulation and virtual environments.
  • Use technology and information resources to research issues in human-computer interaction.
  • Write clearly and concisely about HCI topics using proper writing mechanics and technical style convention
