🚪 Doors can be confusing because their design does not indicate how to open them without trial and error.
🔘 Discoverability and understanding are crucial in good design, whether it's for doors or complex devices.
🏭 Design plays a crucial role in optimizing the function, value, and appearance of everyday products and systems.
🤔 Machines require precision and accuracy, which humans are not always good at. When machines fail, operators are often blamed instead of the design.
🔧 Designers often lack an understanding of human behavior, leading to deficiencies in human-machine interaction and frustration with technology.
👥 Human-centered design (HCD) puts human needs and behavior first, focusing on effective communication and designing for both anticipated and unexpected situations.
🧩 The design of everyday things should aim to create positive user experiences and understanding leads to a feeling of control and satisfaction.
🤔 Cognition and emotion are closely linked, so designers must consider both when creating products.
🔍 Discoverability is important in product design and can be achieved through concepts such as affordances, signifiers, mappings, feedback, and conceptual models.
💡 Affordances are the relationship between the properties of an object and the capabilities of the user, enabling users to understand how to interact with objects.
❌ Anti-affordances are the prevention of certain interactions with objects and need to be discoverable.
🚩 Signifiers are visual or physical cues that communicate the actions or interactions that are possible with a product.
🔍 The role of signifiers in communicating appropriate behavior to users.
🚩 The importance of deliberate and accidental signifiers in providing valuable clues about the world and social activities.
👥 The significance of signifiers in guiding users on how to interact with designs and the distinction between affordances and signifiers.
🗺️ The concept of mapping in design and its impact on the relationship between controls and devices being controlled.
🔑 The relationship between a control and its results is easier to learn when there is an understandable mapping between them.
🧩 Feedback is essential in design to communicate the results of an action, but it must be immediate, informative, and not excessive.
💡 Conceptual models and mental models help users understand and interact with products, but they should be simple and align with users' assumptions.
🧠 Conceptual models are mental representations that people form to understand how things work.
✂️ Tools with visible and clear operating parts, such as scissors, allow for easy conceptual modeling.
⌚ Devices with unclear or non-existent conceptual models, like a digital watch with ambiguous buttons, lead to difficulties in use.
🌡️ Misleading conceptual models, as seen in a refrigerator with confusing controls, result in frustration and ineffective use.
🔧 Providing accurate and clear conceptual models for devices improves usability and user satisfaction.
📚 Good design requires clear communication and providing understandable information to users.
⚖️ Technology offers benefits, but also adds complexity and frustration, requiring careful design considerations.
🔑 Successful design involves the cooperation of multiple disciplines and satisfying various requirements and perspectives.
