Living With Complexity: Microblogs

Chapter One

Summary

Basic ideas of complexity within the world are explored. The difference between complexity and being complicated is explained. Complex things may be able to be mastered over time and could even be enjoyable. On the other hand complicated items can be confusing and difficult to use

Discussion

Yes, complexity exists in the world. From this first chapter it is not clear where this argument is heading. There is both support for complexity and simplicity.

Chapter Two

Summary

Individuals are largely responsible for the creation of either complex or simplistic models of understanding. Norman argues that people create their own conceptual models and choose either simple or complex at this stage. There are further arguments for the complexity of even simple items. Norman settles on middle ground -- focusing on understandability regardless of complexity.

Discussion

I appreciate the focus that is given to establishing a balance between simplicity and features. Too often, I find that products are overly simplified or overly complicated -- it is definitely a place where the perfect balance must be found. Example: iPhone too simple, Android too complex.

Chapter Three

Summary

Norman explores the fact that simple everyday items are often complex in nature of understanding. As an example he complains about having to maintain multiple passwords. This leads to the storage of the passwords within the physical world, which leads to the defeat of the purpose of passwords. Forcing functions are explored as a manner for constraining understanding of information.

Discussion

This felt like a return the Design of Everyday Things and its involved discussions of Norman's dislike of everyday items which are complex. Good points about using forcing functions to help shape user behavior are made here though.

Chapter Four

Summary

This chapter focuses on indicators which can be embedded into design to provide individuals who are using the device with direction. Signifiers, which seem much like affordances, are said to be perceived affordances. A discussion of the differences of culture on signifiers is presented

Discussion

This chapter makes good points about people looking for social cues within their environment and from other people. It is evident that design should include affordances which act as signifiers for the user to understand how to best use the device.
