From [[Book - Laws of UX - Using Psychology to Design Better Products and Service]] My Summary: 1. Design needs to be simple and meaningful, which means, only showing relavent options at the right time. 2. Remove elements that are not useful to help people reach their goals 3. That's why understanding users is very important. 4. Include them to help sort information (according to their mental model) The time it takes to decide increases with the number and complexity of choices available. Key Takeaways - Minimising choices when response times are critical to increasing decision time. - Break complex tasks into smaller steps to decrease the cognitive load. - Avoid overwhelming users by highlighting recommended options. - Use progressive onboarding to minimise cognitive load for new users. - Be careful not to simplify to the point of abstraction. ---- - - Reducing to essential options. Minimalism. Elegance - Understanding what the user needs is essential, you don't have to give too many options. William Edmund Hick and Rayman, 1952. - Increasing choices also increases response time. - Because too much choices.. too busy.. users need to use more brain power to decide : Cognitive Load. Psychological Concept - Cognitive Load, require mental resources (Need more RAM to process) - Tasks become more difficult, and increase frustration and user will stop using it. ![[Screenshot 2023-06-18 at 1.37.36 PM.png]] ![[Screenshot 2023-06-18 at 1.37.47 PM.png]] - Give the right options at the right time. - Keep user focused on the meaningful tasks at hand. - Progressively introduce users to more features. Build upon each steps # Technique ### Card Sorting - To figure how to organise information according to users' mental models. (Implication: How to organise psychoeducation information, features) - 1. Identify Topics - Ask users to organise the content - 2. Organise Topics - Have participants organise topics into grouping - 3. Name Categories - Ask participants to name the categories - Describe out loud their process - 4. Debrief Participants (Optional) - Explain rationale, understand why they organise it that way # Key Consideration Oversimplification - But don't oversimplify to become an abstraction. - They don't understand what they mean.. - ICONS - need to have wide representations.... if not, different icons represent different things to different people. Confusion can happen. - Add contextual tools - text labels to give clarify
