  1. Prototype & Design Computer Inputs

  2. How to Prototype & Design Computer Inputs • Step 1: Review Input Requirements • Step 2: Select the GUI Controls • Step 3: Prototype the Input Screen • Step 4: If Necessary, Design or Prototype the Source Document

  3. Example

  4. User Interface Design • User interface design is the specification of a conversation between the system user and the computer.

  5. Interaction Methods and Devices • Command Language Interaction • Natural Language Interaction • Form Interaction (Fill-in-the-blank) • Key-word search • Menu Interaction • Object-Based Interaction (GUI)

  6. Controlling Data Input • One objective of interface design is to reduce data entry errors • Role of systems analyst is to anticipate user errors and design features into the system’s interfaces to avoid, detect and correct data entry mistakes

  7. The Process of Finalizing Design Specifications • Outcome • Set of physical design specifications • Contains detailed specifications for each part of the system

  8. Assignment: Input/Output Design • Sample reports: outputs created from your prototype system OR your design • Sample Input forms
