Intro to HCI
Define HCI?
The study of how people/humans/users interact with computers.
Name the cognition processes.
Attention, Perception, Memory, Learning, Reading, Speaking and listening and Problem solving, planning, reasoning and decision making
How can we determine if a UX is a poor design?
Comparing strengths and weaknesses of existing interactive products
What is a makes up a good concept model?
High level description a system operations and enables designers to straighten out their thinking beforehand
What are some undesirable aspects of user experience goals?
Annoying, childish, unpleasant, frustrating, boring, etc.
What tools do we use to evaluate interaction design (i.e., tools used in usability testing)?
Observations, Talking, Interviewing, Modeling performance, Questionnaires, Asking them to be co-designers
What are the similarity and difference within Reading, Speaking and Listening and what are some applications that utilize them?
Meaning of sentences that are read. People can listen, speak and read differently based on the context. Applications ex. Interactive books
When designing a framework, what are the components of creating one?
Questions, Steps, Concepts, Challenges and Principles
Define usability goals.
Viewed as being concerned with meeting specific usability criteria (e.g., efficiency)
What is HCI presently concerned with regarding the user experience?
Concerned with understanding, designing for, and evaluating a wider range of user experience aspects.
Name some components of Interaction Design.
Psychology, Computer Science/Software Engineering, Human Factors, Graphic design, film design, etc.
Name the cognitive frameworks.
Mental Models, Gulf of Execution and Evaluation, Information Processing, Distributed Cognition, External Cognition and Embodied Interaction
What is distributed cognition?
The nature of cognitive phenomena across individuals, artifacts and internal and external representations.
Why is it important to understand the user before implementing an interaction style?
The user drives the design in order for it to be optimal and effective.
In usability goals, what does safety entail?
Range of errors the user can make and being able to recover easily from them.
Name one of the common design principles and define it.
Visibility, Feedback, Constraints, Consistency, Affordance.
What do mental models involve?
Developing the knowledge of how a system works and how users interact with it.
Name and define an interaction type.
Instructing, Conversing, Manipulating, Exploring
Recycle bin ex.
Name one of McCarthy and Wright’s four core threads that make up our holistic experiences; and define it.
Sensual Thread, Emotional Thread, Compositional Thread, Spatio-temporal Thread
What does the process of interaction design entail and why is it important?
Evaluating the design, understanding the user and people in different contexts, collaborative planning tool, and avoiding incorrect assumptions. Needed to improve the overall user experience.
Define embodied interaction and give an example.
Understanding interaction in terms of practical engagement with social and physical environments. Ex. instagram close friends feature.
How can an incorrect assumption negatively impact the user experience and build of your tool?
Affect the sensitivities of the users. Can overspend with redesigning and reallocating your design team per expertise.
What are Shneiderman’s framework core principles
Continuous representation, Rapid reversible actions and Physical actions and buttons pressing
Come up with a usability question for Learnability.
Question that determines whether the user can learn the operations of different features within the user interface by exploring the tool/application.
