"Such a rich set of affordances” - A Hypermedia Tale - Mike Amundsen's Presen...CA API Management
The document discusses the concept of affordances and how they relate to hypermedia. It profiles several theorists who contributed to our understanding of affordances, including James Gibson who coined the term affordance, Donald Norman who applied it to product design, and Roy Fielding who related it to hypermedia and REST. The document also references the work of Alfred Korzybski and how language relates to our perception of the world. Overall it explores how a rich set of affordances allows users to discover new possibilities in a hypermedia system beyond what designers may have envisioned.
This document summarizes a study evaluating the interaction design of tablet journalism in Brazilian news publications. It found that (1) affordances were not properly communicated, causing users difficulties perceiving additional content and navigation mistakes, (2) there were false affordances like non-tappable headlines and navigation buttons that did not function as expected, and (3) usability problems with visibility, feedback, consistency and discoverability. The study concluded that Brazilian news apps were too based on print models and lacked dedicated UX design roles, resulting in interfaces that did not effectively communicate their functionality to users.
Cognition, cues, nudges and affordances in mobile communicationTyler Gayheart
This document discusses theories related to how people interact with and use mobile technologies. It covers Gibson's theory of affordances, how the environment provides opportunities for use. It also discusses Sundar's MAIN model for understanding cues and affordances in digital media. Mobile communication is defined by what technologies allow, not just physical attributes. Structuration theory examines how individual behavior and social systems influence each other. Habits and automatic behaviors shape how specific modes of mobile communication are used. The document proposes a dual process affordance model and discusses opportunities for future research at the intersection of affordance theory, heuristics, cognition and mobile communication.
This document outlines a basic web development class that covers UI/UX principles, HTML/CSS/JavaScript, and website evaluation. The class schedule includes presentations on UI/UX principles and website projects. The document then provides details on UI/UX principles, including definitions of UI and UX, examples of good and bad design, and key principles like aesthetics, usability, affordance, responsiveness, and brand image. Students are assigned an exercise to evaluate a company website and create a PowerPoint presentation demonstrating UI/UX principles and including examples of bad design.

The document summarizes Lecture 3 of the Human-Computer Interaction Course 2014 given by Lora Aroyo. It discusses interaction design concepts like design principles, affordances, constraints, mappings, feedback and visibility. It also outlines four psychological principles of user interaction and how they can be applied in design. Specific concepts like consistency, affordances, mappings, feedback and cultural associations are explained in detail along with examples. Design guidelines, standards and principles for optimizing the user experience are also presented.
The document discusses design principles from Don Norman's book "The Design of Everyday Things" and another book on interaction design. It outlines several important principles: visibility (can the user see what to do?), feedback (does the user know the effect of their actions?), affordance (how do controls suggest their use?), mapping (is the relationship between controls and effects clear?), constraints (are invalid actions prevented?), and consistency (is use of the design logical and predictable?). Examples of both good and poor implementations of these principles in everyday designs are provided.
