COMP33511 User Experience

We introduced the appendices section of the course material. He explained that the appendices contain supplemental information that is not directly examinable but provides useful context. The appendices include a paper he wrote on balancing quality and quantity in UX, multiple definitions of user experience and accessibility from different sources to illustrate the lack of a single agreed-upon definition, expanded information on ethics, a list of identified typos and errors, references, and a glossary of key terms. Simon emphasized that understanding the appendices can provide additional marks on assignments and a better learning experience and understanding overall.

- User experience is still being defined but has expanded beyond traditional HCI to include qualitative factors - UX design considers everything around an interface, not just the interface itself - Computers are now for enjoyment beyond just work - Agile is good for known requirements, DevOps and microservices help with separation of concerns - Heuristics can be passed to engineers to understand UX expectations - Validation includes testing initial user requirements through methods like A/B testing Text Transcript: https://web.cs.manchester.ac.uk/zzalszsh/podcast/17-Chapter-18.txt PDF Transcript: https://web.cs.manchester.ac.uk/zzalszsh/podcast/17-Chapter-18.pdf Subtitles : https://web.cs.manchester.ac.uk/zzalszsh/podcast/17-Chapter-18.srt

We discuss how real-world user experience work is often messy, imperfect, and constrained compared to the ideal scenarios described in textbooks. He outlines several common constraints like tight deadlines, inadequate funding, and stakeholders who just want to check boxes rather than make meaningful changes based on feedback. However, there are still things UX practitioners can do even with constraints, like informal discussions or small lab studies to gather initial feedback and ideas. The key is managing expectations that real work will not be perfect and setting realistic goals based on available time and resources.

We provided an overview of evaluation and analysis in user experience design. He explained that evaluation involves scientifically testing hypotheses about whether designs meet user needs. There are different types of variables involved like stimuli, responses, and participant demographics. Both quantitative and qualitative methods are used, like hypothesis testing and grounded theory. Descriptive statistics describe sample data, while inferential statistics make inferences about populations. Due to typical sample sizes in UX, non-parametric statistical tests are generally more appropriate than probabilistic ones. Simon emphasized understanding these concepts at a high level without worrying too much about statistical details.

We provided an overview of digital phenotyping and human-in-the-loop systems. For digital phenotyping, he explained that it involves analyzing people's behaviors and activities through digital means like mobile devices and online activity in order to gain insights into people's lives and needs. For human-in-the-loop systems, he discussed that they integrate humans actively into control systems, rather than just having humans provide input. He noted that this approach was pioneered by NASA and is now also important in AI. He also discussed an example of using digital phenotyping to track Parkinson's disease progression by analyzing social interactions and locations from sensor data.

The podcast discusses principles of digital engagement and user experience, referring to an intangible quality of "digital umami". It covers the importance of group dynamics and social aspects in apps. It also discusses concepts like gamification, playfulness, and facilitating progression in apps. However, it cautions against simply adding these elements without thought, and notes they may not always be appropriate. The key is to thoughtfully consider how these principles could facilitate engagement for each specific application.

- Principles like quality, aesthetics, and flow are subjective and difficult to measure quantitatively. - Lings Cars seems to break design principles but is popular because it reflects the unique personality of its creator, Ling. The "personality principle" may sometimes be more important than other principles. - Affective computing is different - it's about computers recognizing and having emotion, not designing systems to elicit emotion in users. - These principles are challenging to isolate and present to companies because they are so intangible and qualitative.

Usability should be thought of not just in terms of task completion time and speed, but also the quality of what is accomplished. He also says that there are principles that can facilitate usability, such as familiarity, learnability, robustness, progressive disclosure, and scalability, which software engineers and developers may not be explicitly aware of. So from a UX perspective, it's important to elaborate on these principles to developers and engineers so they fully understand best design practices for usability according to UX.

We discussed different levels of prototype fidelity from low to high. Low-fidelity prototypes like paper sketches require more user input but less work from designers. High-fidelity prototypes look closer to the final product but require less user input. He emphasized testing prototypes with users early and often to incorporate their feedback. Rapid application development can generate working prototypes even without complete backend logic, using a "Wizard of Oz" approach to simulate interactions. The overall goal is to get user feedback at various stages of the design process through prototyping.

We discussed how agile development and user experience are well-suited approaches for building user-centered software. He explained that agile development with its iterative process allows for continuous user involvement. For research projects or prototypes, cowboy coding may be more appropriate. He recommended using Flutter/Dart for cross-platform user interfaces and Rust for performance-critical backend services. Simon Harper also advocated for a microservices architecture with decoupled services communicating over a message bus, to facilitate parallel development and operations. Overall, he emphasized the importance of user research, cross-platform design, and rapid iterations in developing user experiences.

An overview of different methods for modeling requirements captured through user research activities like observations, interviews, and questionnaires. These include informal methods like user stories, semi-formal methods like personas, scenarios, wireframes and mockups, and more formal methods like use cases, flowcharts, and UML diagrams. He emphasized that the level of formality should match the needs of the development process and that a spectrum of methods can be used together. He also cautioned against groupthink and ensuring user evaluation matches the original specifications.

We discussed various methods for gathering user requirements for software projects, ranging from more in-depth approaches that take months like participant observation to more lightweight approaches that can be done in days like interviews. He emphasized the importance of putting users at the center of the design process through techniques like user-centered design. Post-it notes, prototyping, and informal conversations were also presented as useful ways to elicit feedback from users. The transcript covered tradeoffs between different timelines and strategies for gathering requirements when user access is limited.

- UX needs to account for the complexity of human behavior and minimize complexity people face when using systems. Systems should handle complexity, not users. - Visual and auditory channels are primary ways humans receive information. Interfaces can leverage both to provide parallel information streams. - Other sensory channels like touch, smell and taste can also provide input in some contexts. Research showed smells linked to data helped with information retrieval. - Cognitive factors like learning, memory and familiarity impact usability and should be considered in design. - Standard input methods like keyboards, mice and touchscreens maximize human abilities but specialized domains may require different inputs. - The talk covered many types of inputs, outputs and how people process information to provide an overview of human-computer interaction factors in UX design.

- Tom's Diner had a significant impact on the development of mp3 audio format. When Karlheinz Brandenburg heard Suzanne Vega's a cappella version of the song, he realized it would be a good test case to push the limits of his audio encoding scheme. Using a challenging song like this helped improve the encoding and led to the creation of mp3, which revolutionized digital music. - The mp3 format allows for small file sizes while still providing good audio quality. This improved the user experience of listening to digital music on devices with limited storage like early MP3 players. It made transporting and sharing large music libraries much more practical. - A good user experience is important not just for desktop and mobile apps, but also for embedded systems and anything involving digital media and audio/visual content. Tom's Diner is an example of how even something as simple as a song can significantly influence technological development and ultimately impact many people's everyday experiences with digital music.
