Lecture 4 Flashcards
What is Adaptive Morphology
The evolution of form where less is more
What are the three factors to consider in tool evolution
Discovery, Invention/Intent, Purposeful Observation
Three Mutation Theories
Primary Mutation, Free Mutation, Cross Mutation
What is Primary Mutation
Creating desirable forms by interaction with another form
What is free Mutation
Changes that occur through accident or intent to improve the function
What is Cross Mutation
A re-adaptation of one artefact to another
What characteristics does the human body’s influence on tool design
Size, mobility and shape of the human hand
Length and strength of the arm
Power of the leg
Focus and power of the eye
Three Dimensions of Human Factors
- Capabilities of the Human Body (Anthropomorphic, Bio Mechanics)
- Matching the reasoning power of the human mind
- Matching the surroundings where the human lives and works
Who was the pioneer for ergonomics/anthropomorphic
