๐ช Doors can be confusing because their design does not indicate how to open them without trial and error.
๐ Discoverability and understanding are crucial in good design, whether it's for doors or complex devices.
๐ญ Design plays a crucial role in optimizing the function, value, and appearance of everyday products and systems.
๐ค Machines require precision and accuracy, which humans are not always good at. When machines fail, operators are often blamed instead of the design.
๐ง Designers often lack an understanding of human behavior, leading to deficiencies in human-machine interaction and frustration with technology.
๐ฅ Human-centered design (HCD) puts human needs and behavior first, focusing on effective communication and designing for both anticipated and unexpected situations.
๐งฉ The design of everyday things should aim to create positive user experiences and understanding leads to a feeling of control and satisfaction.
๐ค Cognition and emotion are closely linked, so designers must consider both when creating products.
๐ Discoverability is important in product design and can be achieved through concepts such as affordances, signifiers, mappings, feedback, and conceptual models.
๐ก 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.
โ Anti-affordances are the prevention of certain interactions with objects and need to be discoverable.
๐ฉ Signifiers are visual or physical cues that communicate the actions or interactions that are possible with a product.
๐ The role of signifiers in communicating appropriate behavior to users.
๐ฉ The importance of deliberate and accidental signifiers in providing valuable clues about the world and social activities.
๐ฅ The significance of signifiers in guiding users on how to interact with designs and the distinction between affordances and signifiers.
๐บ๏ธ The concept of mapping in design and its impact on the relationship between controls and devices being controlled.
๐ The relationship between a control and its results is easier to learn when there is an understandable mapping between them.
๐งฉ Feedback is essential in design to communicate the results of an action, but it must be immediate, informative, and not excessive.
๐ก Conceptual models and mental models help users understand and interact with products, but they should be simple and align with users' assumptions.
๐ง Conceptual models are mental representations that people form to understand how things work.
โ๏ธ Tools with visible and clear operating parts, such as scissors, allow for easy conceptual modeling.
โ Devices with unclear or non-existent conceptual models, like a digital watch with ambiguous buttons, lead to difficulties in use.
๐ก๏ธ Misleading conceptual models, as seen in a refrigerator with confusing controls, result in frustration and ineffective use.
๐ง Providing accurate and clear conceptual models for devices improves usability and user satisfaction.
๐ Good design requires clear communication and providing understandable information to users.
โ๏ธ Technology offers benefits, but also adds complexity and frustration, requiring careful design considerations.
๐ Successful design involves the cooperation of multiple disciplines and satisfying various requirements and perspectives.
