Interaction Design

Interaction Design

1. Pros And Cons

   • Pros
     • User Centered Design
     • Low Support Costs
     • Improved Product Reception
     • Inherently Iterative Designs
   • Cons
     • Low focus on functionality over form
     • Extra work might need to be done to accomodate Designs
     • May have to rework the product frequently

2. Aims

   • interactive and effective products
     • Users' perspectives
       • Pleasurable to Use
       • Effective
       • Easy to Use

3. What?

   • designing interactive products to support the way people communicate and interact in their everyday and working lives
     • Intuitive UI
       • Natural
         • Is consistent with how we would use the system if it were novel to us
       • Learnable
         • Easy
           • Little novelty or learning cost to the interactions
       • Pattern
         • Expected
           • Behaviour results align with those that have been seen before
           • Assumes previous interactions with similar systems
       • Flow
         • Engaging
           • Small amounts of novelty to keep interest
           • Feedback - interaction cycles between the user and system
         • Deliberate Practice

4. GOOD VS POOR

   • Good Design
     • Taking into account what people are good and bad at
     • Considering what might help people with the way they currently do things
     • Thinking through what might provide quality user experiences
     • Listening to what people want and getting them involved in the design
     • Using tried and tested user-based techniques during the design process
   • Poor Design
     • Irritating
     • Confusing
     • Inefficient
     • Not obvious

5. Forms of Guidance

   • Visibility
   • Findablity
   • Feedback
   • Constraints
   • Consistency
   • Affordability

6. UXP and Usability Relationship

   • User Experience
     • ­ How do people feel about it when looking at it or using the product?
   • Usability
     • Utility, safety, efficiency, memorability, effectiveness, learnability
   • Relationship - maintain those usability aspects, and get feedback from user based on the aspects

7. Process

   • What?
     • establish requirements
       • Functional
       • Aesthetic
       • Technical
     • design alternatives
     • prototypie
       • Quickly put together models for testing interaction concept
     • evaluate
       • Does it function as needed
       • Does the user enjoy interacting with the system
       • Could the effectiveness of the system be improved
     • repeat as needed based on feedback!
   • Why User-centred approach?
     • Form is as important as function
     • User doesn't care/need to know about the inner workings of the system
       • Results are most important thing to the user
       • Systems can be changed without effecting the user
       • Doesn't overload the user with unnecessary information
     • Accessibility
       • Should be usable by as wide an audience as possible
         • Maximizes audience
         • Reduces support cost
       • Don't want to have to remake entire modules so different user groups can use the system
         • Disabilities
         • Cultures
         • Previous experience
   • Who?
     • Designers
     • Artists
     • Engineers
     • Programmers
     • Psycologists
     • Sociologists
     • Marketing

8. How it relates to HCI

   • all of them are working to make human life becomes easier to interact with products

9. Influencing Concepts

   • Users
     • How people react to events
       • How people react & interact with each other
     • How the product influences people's emotions
       • Create engaging user experiences
       • Aesthetics
       • Desirability
     • Expectations
       • Previous experience
       • Consistency within the system
   • Design
     • How a product behaves
     • How do people feel about the product
   • The way to interact
     • Buttons
     • Typing
     • Swiping
     • Speaking
     • Gestures
   • Computer
     • How the user can interact with the computer
     • How the user wants to interact
     • How the user is intended to interact
