Study Notes
Cognitive Load and Task Completion
- Minimizing the need for users to learn an interface enhances focus on completing main tasks efficiently.
- Prioritizing familiarity and patterns reduces mental effort and streamlines task completion.
Design Principles
- Designing digital products should prioritize task completion over complexity and novelty.
- Pattern-based design helps reduce cognitive load and prioritize task completion.
Jakob's Law
- Jakob's Law emphasizes the importance of matching design to users' mental models based on past experiences.
- Recognizing users' mental models and designing interfaces accordingly aids in user-focused design.
User-Focused Design
- Utilizing user personas constructed from real data helps define the target audience and shape user-focused design.
- Relying on intuition and assumptions about potential users' traits and behaviors is not an effective design approach.
Aligning Design with Users' Mental Models
- Aligning design with users' mental models enhances usability and task completion efficiency.
- Jakob's Law emphasizes the match between design and users' expectations and mental models.
Fitts's Law
- Fitts's Law is primarily concerned with the time it takes for users to move to and engage with interactive objects.
- As the size of an object increases, the time it takes to select it decreases.
- Fitts's Index of Difficulty (ID) is calculated by the formula: ID = log2(2D/W).
- Key considerations for touch targets according to Fitts's Law include large enough size, sufficient spacing between targets, and placement in easily accessible areas of the interface.
Form Submission Buttons
- Fitts's Law impacts the design of form submission buttons, which should be positioned close to the last form input.
Miller's Law
- Miller's Law states that we can typically hold around 5 plus or minus 1 items in our working memory.
- Chunking, which involves breaking down information into smaller meaningful clusters, is significant in relation to Miller's Law.
Learn about the importance of minimizing cognitive load and prioritizing task completion in digital product design. Understand how design principles and Jakob's Law can help.
