Week 9-Design and Prototyping by Eyok

High Fidelity & Low Fidelity Prototyping Tools

Prototype:
an early sample or model for a product before it is finalise and mass produce.It is also use for testing by replicate a lot or learned from errors when testing.


what can considered a prototype:-
- paper based outline of a screen/sets of screen.
- Electronic 'picture'
- 3 dimensional paper/cardboard mockup
- stack of hyperlinked screen shots


Benefits of having prototype models :
- hand on testing in realistic setting as many as possible as long as prototype models are a lot.
- explore imagine uses *some of the setting sometimes is impossible to create.*
- interact with envisioned product


Low Fidelity Prototyping Tools :
- different design then the final product.
- it is simple,cheap and quick to produce
- using material like paper and cardboard rather than create in computer software and show to screen
- important during conceptual design are never intended to kept and integrated into final product.They are for exploration
only.

High Fidelity Prototyping Tools :

- using good material that would expected like final product including appearance and also material.
- prototype tools -Flash ,Visual Basic, smalltalk
- issue for creating high fidelity prototyping =

1) take a lot of time to built
2)reviewers and tester tend to comment on superficial aspects rather than
content
3)developer reluctant to change something that they crafted so long
4)a software prototype can set expectation high.
5) 1 error can destroy the whole model.
