Ergonomics: PRACTICAL #7 Card Sorting and Affinity Diagramming

Ergonomics


Ergonomics: Designing for a range of people/body types so they are efficient and  comfortable.

Height, arm length, grip strength, finger length, etc are all physical qualities we should consider in our designs. Each population has their own averages.

Biochanics: the study of the structure, function and motion of the mechanical aspects of biological systems, at any level from whole organisms to organs, cells and cell organelles, using the methods of mechanics. 

 ex. measuring diameters of door hands compared to grip strength. Tool designs people need to consider the jobs it will be used for and what bad habits they can 


Design the physical interactivity. How do people interpret the world and interact with the things around them? Why do they do those things? Why are certain things more intuitive or convenient than others.

Affinity Diagrams and Card Sorting

Card sorting: working with users to design an understandable information structure for something (website, app, software). Ex. Navigating a site like amazon they need to think of the grouping and categorization of products and functions. using the right kind of language is crucial.  


It was a great exercise that made us aware of our different ways of perceiving the world. We categorize things differently internally and had to compromise where and how to sort the things at the café. A danger designers with different thinking run into is creating too many categories or sticking all the things that don't seem to belong to their categories into "Other". We used productive cheating to compare our categories to pre-existing ones on different café websites. We also used ChatGPT to generate café items for our menu.

Affinity Diagramming: Organizing the experience of the user. We decided to organize it into actions at the café/ the duration. We
Here!


We revisited our Costa observational research data to diagram and organize the user experience. We decided to use a mind map that went through the journey of being at a cafe. Entering to departing. We included things they encounter and used emojis and colors to express emotions and whether it was positive or negative. 

SRS: Software Requirements Specification 
Specifies what will be built (requirements and expectations)
There are functional and non-functional requirements. 
Design Requirements: Define user requirements and specify usability should do and what the quality of the XP should be like

Slow Computing, Digital Civics and Portfolio Project

 Slow Computing & Digital Civics Slow Computing: - Cultural shift towards slowing down life's pace - Computing is deeply imbedded in our lives - Slow computing VS Calm technology     - calm tech promotes moments of reflection and mental rest. The info is presented passively and it's usually in our poriferas.  - Some Design: meditative bodily introspection -Fast Technology: well-defined task, efficient, easy to use Reflection: Most companies are focus on quick profits, fast technology. Slow technology cares more about the users mental wellbeing. As UX designers we need to design for slowness, solitude and mental rest. How do we change the functionalities and design to help the users not get overwhelmed? We could avoid numbers based goals and information. We should reward users for taking their time and  "Living Technology Lives", people are always on their phones and rely on it heavily. It has become an assumption that everyone has a smartphone and is online 24/7.

* Research: Different Analysis

Image
  Research Methods - Be transparent about what your biases are/could be in your research. - Theme names give some indication of what problem you are addressing -Appendices will give people opportunity to check your code and data Thematic Analysis: Look for patterns (Themes, hence the name) across textual data. The examples he showed was transcripts from conversations between researchers. He also showed us an example where the designers that updated the Metro used Mural to organize their themes and notes on the different areas that need to be addressed in their design. The themes can have subcategories that are more descriptive( CCTV--> Anti-social behavior). The Process:  Familiarization--> coding --> generate themes --> review themes codes --> define and name themes --> write up analysis  Grounded Theory: This one is different because you don't have a specific theory or hypothesis (or preconceptions about the theory). You just select an area of interest and begin

Week 2: Lecture 4 Ideation, Co-creation and concept sketching

 Ideation and Concept Sketching Project expectations: Communicate a critically analyzed design  Don Normans 4 Principles: 1. Understand people 2. Focus on the people 3. Solving the right problem not the symptoms     -Users may tell you small problems(Symptoms) and it's your jobs to identify the bigger problem 4. Always be iterating and improving Card-based Techniques for Ideation: When designers are developing ideas it forces yourself to consider different design/user aspects  Why? help us better understand the end user population and the research context or setting  What? Think about ideas and sensitize people to the ethics. Evokes consideration and discussion of longer term effects
