Section 2- Interaction Design Basics Flashcards
Define Motion
- The way products behave in response to the way that people behave
- Triggers for actions
Define Space
Two or three dimensional within physical, digital, and analog realms
Define Time
- The duration of motions and actions.
* All interactions take place over time
Define Appearance
- How something looks or behaves.
- Is known as an affordance, or referenced by central and/or cultural perceptions
- Proportion, structure, size, shape, weight, and color
Define Texture
- How an object feels
- Has several affordances (solid, flimsy, fragile, durable)
- Vibrations and Heat
Define Sound
- Any audio element in space
- Pitch
- Volume
- Timbre or tone
Name the Laws of Interaction Design
- Moore’s Law *Hick’s Law
* Fitt’s Law *Testler’s Law of Conservation & Complexity
Define Moore’s Law by Gorden Moore - Cofounder of Intel 1965
States that every 2 years the number of transistors on integrated circuits will double
Define Fitts’ Law:
States that the time it takes to move from a starting position to a final target is determined by the distance to the target and size of the target
Define Hick’s Law:
States the time it takes for users to make decisions is determined by the number of possible choices they have
Define Testlers’ Law of Conservation and Complexity
States that some complexity is inherent to every process… a point is reached to where a process cannot be simplified any further
What is another name for the Poka-Yoke Principle and what does it mean?
- Known as “Mistake Proofing” or “Idiot Proofing”
- Avoiding inadvertent errors
EX: computer components only fitting into specific slots
Describe the difference between Direct Manipulation and Indirect Manipulation
Direct - Selecting a digital object with haptic device, we can perform a motion/action to do it
Indirect - Process of manipulation of an object via commands or other means that is not a part of the digital object itself
What is Feedback and Feedforward?
Feedback - Indication that something happened
Feedforward - Knowing what will happen before you perform an action
What are the Characteristics of Interaction Design?
- Trust worthiness ( how users see the product or service)
- Appropriateness ( need of product or service relation to cultural,situational,and context of users)
- Smart ( level of intelligence of the project or service)
- Responsiveness ( how products/services respond to user inputs/commands)
- Clever ( Products/Services predict the needs of users and fulfill unexpectedly)
- Ludic ( how product/services facilitates play among users to increase engagement)
- Pleasurable ( how aesthetically and functionally pleasing a product/service is to users)
