Home Mess System: Design & Prototype Presentation Transcript

  • 1. Home-Mess System
    Presentation II: Design & Prototype 1 Arundhati, Ihab, Ibrahim, Fareed, Zain
  • 2. Introduction
    Prototyping provides us with tangible models which help users visualize possibilities and identify failures.
    Explore the development from an idea to a prototype
    Construct part of the development lifecycle used to provide valuable insight into the look-and-feel, and the general workflow of an application.
    Prototypingis the keynode of iterativedevelopment
  • 3. Objectives
    Defining the Problem
    Identifying user requirements
    Development of a supportive design solution
    Designing of a low-fidelity prototype.
    Creating a working model of the system so that conceptual ideas can be 'road tested', alternatives explored and user feedback gathered at an early stage.
  • 4. User Requirements
  • 5. User Requirements- cont.
  • 6. Design Stage
  • 7. Our Approach
    J. Nielsen distinguishestwolevels of prototypingaccording to the level of interaction.
    Man-Machine Interface
    Functionalities
    Levels of prototyping
  • 8. Horizontal prototype
    It isthe 'surface interface'.
    Functionalitiesare not working, but itallows to achieve a perception test.
    Allowsto check the local behaviour of the interface
    Identifies the critical points whereusabilityproblems are likely to appear.
  • 9. Vertical prototype
    It implements a consistent set of functionalities in order to allow the user to achieve a typical scenario of use. Some of thisfunctionalitiescouldbesimulated.
    This second stage of the prototyping phase consists in a series of user tests duringwhich the critical points raisedpreviously are evaluated.

  • 17. Demo
    Ihab, Arundhati
  • 18. Conclusion
    Prototypes start off as empty shells
    Usability problems detected
    It will be used to to evaluatethe usabilityof the wholesystem.
  • 19. What’s Next?
    Evaluation:
    • Data Analysis: What is new, what could we improve?
    • 20. User Testing: What new problems present themselves?
    • 21. New Designs: Designing to solve problems and appeasing the users.
