Psychological Factors • The issue • People are psychologically complex • Design touches every part of the human experience • Data pertaining to stuff that cannot be seen (touch, taste, smell) are often expressions of opinion rather than fact.

 • Psychological factors are those that impact operations including effects of environmental conditions

• Psychological factors are those that impact operations including effects of environmental conditions such as: • stress • lighting • temperature • humidity • noise • Vibration • These need to be taken into account by the designer in order to improve the user experience.

• Designers study physical characteristics to optimize the user’s safety, health, comfort, and performance. • Use the following when designing for physical characteristics: 1. Physiological factor data (how major organs work and function) • Blood pressure, eye movement, lung capacity, balance, etc. 2. Comfort and Fatigue studies • Design for comfort/discomfort 3. Biomechanics • The study of mechanical laws relating to the movement of living organisms (mostly humans and animals)

More on Biomechanics

 • Within all designs there assumptions about the biomechanical capabilities of a user

• Within all designs there assumptions about the biomechanical capabilities of a user population: • Strong enough to turn the top of a bottle? • Enough dexterity to open a small hatch on packaging?

 • Biometric design assumptions are not just guesses • Based on anthropometric data

• Biometric design assumptions are not just guesses • Based on anthropometric data (dynamic and static) • Some groups do not fit the usual data patterns • The elderly, sick, or disabled • Design for inclusion

• Biometric analysis may be used to examine data related to the use, misuse, or difficulties surrounding product design. • May result in age appropriateness suggestions

 • Biomechanics also come into play with design of packaging. • Lids •
