Study Notes

HCI and Design

Human-centered design is a process that focuses on understanding user needs.
Scenarios and task analysis help in understanding user's tasks, goals, and the contexts in which they are used.
Interviews and ethnography are used to understand what users do, and how they do it in their natural settings.
Evaluation and heuristics assess if the design meets the requirements and solves problems.
Design principles provide guidelines for creating designs that are intuitive, efficient, and enjoyable to use.
Precise specification defines the features and functions for the designed system.
Prototyping is a very important part of the design process. Paper prototyping has many benefits like quick turnaround, flexibility, and cost-effectiveness.
Low-fidelity prototypes can effectively reveal the big picture, like layout, control mechanisms, and usability issues.
High-fidelity prototypes are more in depth and represent the final look and feel of the system.
Mixed fidelity prototypes combine low- and high-fidelity elements.
Vertical prototyping focuses on a portion of the interface to illustrate structure and large amounts of specific elements.
Horizontal prototyping provides a broad overview of the interface.
Prototyping is useful because it allows problems to be addressed before building a full system, minimizing both time and cost. Using prototypes also promotes collaboration, enabling better understanding of user needs and priorities.

Human-Centered Design Process

The process begins with determining user needs and continues with analysis, design, and implementation.
This model involves multiple steps like interviews, scenarios, analysis, evaluation, design, prototyping, and implementation.
The objective is to create a successful product that satisfies user needs.

Paper Prototyping

Paper prototyping is a low-cost method to test designs and collect feedback from potential users.
It uses paper materials like unlined paper and 8x5 cards.
Tools like adhesives, markers, sticky pads, and scissors can help enhance the prototyping process.
The goal is to get as much user feedback as possible.
Using a photocopier or camera can assist in quickly recreating elements like buttons, screens and other parts of the design.

Preparing for Testing

Perform user and task analysis.
Determine user backgrounds and the kind of tasks they would be doing with the product or system.
Users can have different levels of knowledge about technology.
Prepare the scenarios that users will use.
Identify and resolve bugs or issues that could arise before user testing.
Preparation includes familiarization with the prototype to improve comfort during the session.

Conducting Testing

A facilitator guides users through tasks, encouraging feedback without influencing decision-making.
Users provide input, addressing usability issues, which are then evaluated and prioritized for improvement.
Observers take notes and focus on possible solutions to problems identified during testing.

Evaluating Results

Summarize the identified issues.
Evaluate the results concerning the usability of the prototype and the functionality of the system.
Prioritize the issues based on their severity and potential impact.
Develop a revised prototype based on identified usability issues and incorporate updates to address the prioritized issues.

Why Use Paper Prototyping?

Cost-effective
Fast turnaround time, allowing for quick iteration
Facilitates collaboration between stakeholders
Focuses on fundamental usability issues
Users provide quick and candid feedback
Shows how users interact with the interface, and where the major problems are.
Paper prototypes are a rapid testing method, which significantly reduces overall costs and delays.
Quick feedback allows for rapid design adjustments.

Why Not Use Paper Prototyping?

May not represent complex effects or features
Might not be considered a professional enough method by some users or stakeholders.
Doesn't produce any tangible or concrete deliverables.
