Design, Prototyping and Construction

1. Design, Prototyping and Construction www.an-prototype.com

2. The Task-Centered Design Process • figure out who's going to use the system to do what • choose representative tasks for task-centered design • Plagiarize • rough out a design • test it with users • iterate • build it • track it • change it • think about it • create a mock-up or prototype www.an-prototype.com

3. Overview •Prototyping and construction •Conceptual design •Physical design •Tool support www.an-prototype.com

4. Two guidelines for design 1. Provide a good conceptual model allows user to predict the effects of our actions problem: designer’s conceptual model communicated to user through system image: appearance, written instructions, system behavior through interaction, transfer, idioms and stereotypes if system image does not make model clear and consistent, user will develop wrong conceptual model www.an-prototype.com

5. Two guidelines for design (continued) 2. Make things visible relations between user’s intentions, required actions, and results are •sensible •non arbitrary •Meaningful visible affordances, mappings, and constraints use visible cultural idioms reminds person of what can be done and how to do it www.an-prototype.com

6. Prototyping and construction •What is a prototype? •Why prototype? •Different kinds of prototyping low fidelity high fidelity •Compromises in prototyping vertical horizontal •Construction www.an-prototype.com

7. What is a prototype? In other design fields a prototype is a small-scale model: A miniature car A miniature building or town www.an-prototype.com

8. Why prototype? •Evaluation and feedback are central to interaction design •You can test out ideas for yourself •It encourages reflection: very important aspect of design •Team members can communicate effectively •Stakeholders can see, hold, interact with a prototype more easily than a document or a drawing •Prototypes answer questions, and support designers in choosing between alternatives www.an-prototype.com

9. What to prototype? •Technical issues •Work flow, task design •Screen layouts and information display •Difficult, controversial, critical areas www.an-prototype.com

10. Product prototype company gives innovators, product designers and industrial engineers the ability to hold and test as many product prototypes as they require. you will not have to keep rectifying the final product but you can get a perfect and flawless final product. You can visit our website for any requirement. http://www.an-prototype.com/ www.an-prototype.com
