EXCHANGING KNOWLEDGE AND EXPERIENCES

User-Centred Development (a.k.a. User-Centred Design or Human-Centered Design): approach to system design and development that aims to make interactive systems more usable by focusing on the use of the system; applying human factors, ergonomics and usability knowledge and techniques (ISO/IEC 9241-210)

Sometimes you will read human-centred instead of user-centred to emphasize that all stakeholders, and not only users, need to be taken into consideration during the process.

User-Centred Development

EXCHANGING KNOWLEDGE AND EXPERIENCES

It provides methods and techniques to figure out… Specified Users: Who? Specified Goals: What? Specified Context of Use: In which context?

… in order to design for them … and assure certain levels of…

effectiveness, efficiency and satisfaction (quality in use)

… ALL MEASURED AT THE USER INTERFACE LEVEL

User-Centred Development

User-centered development increases the knowledge of user goals early in the development cycle, when the design freedom is higher

User-centered development inverts the development pyramid, making it easier to predict costs.

User-Centred Development

Leonardo da Vinci Partnerships ProjectGUI USABILITY AND ACCESSIBILITY:

EXCHANGING KNOWLEDGE AND EXPERIENCES

It is made up of three disciplines or workflows: User-Centered Analysis (UCA) User-Centered Design (UCD) Usability Testing (UT)

It’s an iterative process

UCAIntroducción: Recopilación Información

•¿Cuándo cada técnica?1. Tipos de datos que se necesita recolectar (tareas, funciones, performance)

2. Nº de personas de las que hay que recolectar datos (<25, >25)3. ¿Datos específicos o datos de exploración?

4. ¿Hay aspectos complejos involucrados?5. ¿Se necesitan rápidamente los datos?

6. ¿Hay restricciones severas de presupuesto?7. ¿Son necesarios muchos datos?

8. ¿Hace falta información sobre errores de usuario?

•¿Ventajas? ¿Inconvenientes?
