DESCRIPTION
THis presentation given at the Desire conference in Eindhoven on 21 October 2011.To be able for students to understand small mechanical principles for use in industrial design, the use of lego TECHNIC can be an easy, explorative way.

Introduction
• Electronic devices are not open to our actions [5]
• Interactions between humans & objects are physical [5]
• Interfaces should touchable, pushable [5]
•"Interaction design is about exploiting human perceptual-motor skills” [5]

Mechanical Interaction
• Several factors determine the quality of interaction
• Mechanical design is one of the cornerstones
• Action and perception cannot be seperated
• Low-quality mechanical design = low quality interaction. [2]
• So quality-driven mechanical design is a key contribution to quality of interaction

Evaluation
• Some theory is hard to grasp, yet very important for (student) designers
• With prototyping tools abstract theory can be made tangible, and understandible
• For students: understanding by doing
• Quick-and-dirty prototyping is fun and usefull!21/10/2011
