Chapter 3 Reading

The Elements of Interaction Design:

  • Motion: The way that products behave in response to the way people behave; motion is often a trigger for action; without motion there can be no interaction.
  • Space: Provides a context for motion; all interaction takes place in a space.
  • Time: The rhythm of the interaction. (digital time is not equal to human time)
  • Appearance: Provides indication of how to interact with an object, often implies emotional context.
  • Texture: The sensation of an object can provide clues as to how it is to be used, as well as when and where.

The Laws of Interaction Design:

  • Moore's Law: Designers can conceive of devices that are faster, smaller and more powerful than could have feasibly been considered before. (Basically technology is always getting getting better)
  • Fitt's Law: The time it takes to move from a starting position determined by the distance to the target and the size of the target.
  • Hick's Law: States that the time it take for users to make decisions is determined by the number of possible choices they have.
  • Magical Number 7: The human mind is best able to remember information in chunks of seven items, plus or minus two.
  • Tesler's Law: There is a point beyond which you can't simplify a process any further. Therefore designers substitute processes that have elements that can't be simplified. "Share the burden of complexity"
  • Poka-Yoke Principle: "proofing-avoiding" Preventing problems from occurring in the first place, by putting constraints on products.
  • Direct and Indirect Manipulation: 2 ways of interacting with digital objects. Directly: closely mapped to our physical experience. Indirectly: use a command or menu that isn't a part of the digital object to alter that object.
  • Feedback and Feedforward: feedback-some indication that an action has succeeded; feedforward-knowing what will happen before you perform an action.

Characteristics of Good Interaction Design:

  • Trustworthy: If users trust that a tool can do the job required, they are more likely to deeply engage with it.
  • Appropriate: Solutions have to be appropriate to the culture, situation, and context they live in.
  • Smart: Tools need to be smarter than us to accomplish a task we cannot do ourselves.
  • Responsive: Good design provides a mechanism  to let the user know that the system has heard the request and is doing something about it. (provides feedback)
  • Clever:  Clever products and services predict their users needs and fulfill those needs unexpectedly.
  • Ludic: Providing the environment and means for users to play with a product or service; users need to feel relaxed instead of trapped.
  • Pleasurable: "Beautiful products work better" BUT for a product or service to be appealing it has to work well.

Chapter 2: Four Approaches to Interaction Design

User Centered Design or UCD:
  • UCD focuses on user needs and goals, where user data is the determining factor in making design decisions.
  • This approach is best at getting designers to move away from their own preferences, and instead focus on  the needs and goals of the users.
  • Follows the philosophy of "User knows best."

Activity Centered Design or ACD:
  • ACD focuses on the tasks and activities that need to be accomplished, rather than the goals and preferences of users.
  • Activity Theory states that people create tools as a result of "exteriorized" mental processes: creating the tool to support the task.
  • *ACD Danger*
    • "You'll get a different result if you set out to design a vase instead of something to hold flowers."

Systems Design:
  • Systems Design is an analytical approach to design that focusses on the components of a system.
  • The user is de-emphasized in favor of the context, but the designer doesn't discount discount user goals and needs.

Genius Design:
  • Relies almost solely on the wisdom and experience of the designer to  make decisions.
  • The approach best used by experinced designers.
