Human Computer Interaction (Lecture 1)

Overview of HCI, UX, and UCD

Introduction

In the past: computers were expensive and only used by technical people
Now: computers are cheap and used by non-technical people with different backgrounds, needs, knowledge, and skills
Interacting with technology is a crucial part of daily life
Computer systems should be easy to use, learn, and free of errors

Additional Points

Buttons on a lift: Both buttons point up
Wrong choice of controls: Example of a poor design choice

Parking Signs in Los Angeles

Overloaded details that contradict each other

User Experience (UX)

User experience encompasses all aspects of the end-user's interaction with the company, its services, and products
UX focuses on understanding users' needs, values, abilities, and limitations
UX takes into account business goals and objectives

UI and UX

UI: The elements that enable someone to interact with a product or service
UX: The experience of the user interacting with the product /service

Factors that Influence UX

Peter Morville introduced seven factors impacting UX (usable, useful, desirable, valuable, findable, accessible, and credible).
Peter Morville is a pioneer in information architecture and user experience

7 Factors of UX

Useful: Content needs to be original and fulfill a need.
Usable: Site/system needs to be easy to use.
Desirable: Design to evoke positive emotion and appreciation; likability.
Findable: Content easily navigable and locatable online (site and offsite).
Accessible: Accessible to people with and without disabilities.
Credible: Users view the content/product as trustworthy.
Valuable: Product delivers value .

User-Centered Design (UCD)

Iterative process focusing on user needs throughout the design and development of a product.
User research important.
Design based on understanding of users, tasks, and environments.
User-centered evaluation
Addresses the entire user experience.

Specific Activities for User-Centered Design

Understand context of use
Identify users, what they need it for, and conditions.
Survey techniques, focus groups are possible tools.
Understand how users interact with the system
The medium, environment, and emotional state.

Specify User Requirements

Define business or user goals required for product success.

Design Solutions

Create solutions to identified problems/requirements.
Utilize tools such as storyboarding, wireframing, designing mockups, and user flows.

Evaluation

Assess evaluation outputs against user context and requirements to assess design performance.
Ideally through usability testing with actual users.

Advantages of UCD

Increased sales and lower costs (customer service).
Products more likely to meet user expectations and requirements.
Safer products tailored to specific contexts and tasks.
Recognition of cultural diversity and values through UCD.

Context of HCI

Context of how the system will be used by the user in daily situations.
User, time, physical, computing context.
User context: information about the end-user.
Time context: absolute time, date, day of the week, and season.
Physical context (temperatures, noise levels, lighting, traffic conditions).
Computing context: resources (networks, bandwidth, communication costs)

Benefits of HCI

Improved productivity
Reduced training needs (workshops and manuals).
Good quality products
Increased customer satisfaction
Greater market share
