Here are some tips for observing strangers respectfully and ethically: - Obtain verbal consent before observing. Explain your student project and ensure anonymity. - Observe from a distance without interrupting their activities. - Focus observations on actions, not personal details. Avoid noting attributes like age, gender. - Be discreet. Do not stare or make the person feel uncomfortable. - Respect privacy. Do not photograph or record without permission. - Be mindful. Observe sensitively and avoid assumptions about the person's identity or situation. - Thank the person afterwards if you introduced yourself. Respect their right to not participate. While observation can provide useful insights, prioritizing the

The document discusses human-computer interaction design. It notes that good design requires understanding users, their needs and expectations. Common pitfalls include lack of early user analysis, usability testing and team communication. Ambiguous interfaces, limited input and complex navigation cause usability problems. The design process involves understanding business functions, human characteristics like memory and speed, and ensuring the interface matches users' mental models through techniques like task analysis and conceptual modeling.

The user interface design process involves understanding users and business needs, principles of screen design, and selecting appropriate controls. Key steps include developing navigation, selecting windows and controls, writing clear text, providing feedback, testing, and considering users, tasks, environments, and hardware when choosing controls. Common input devices include mouse, keyboard, touchscreen, graphics tablet, joystick, light pen, and voice recognition. Controls are direct or indirect based on their relationship to screen interaction.

The document discusses drag and drop interactions from the perspectives of users, events, actors, and purposes. It outlines key questions about how users perceive draggable objects and valid drop targets. It also lists common drag and drop events like hover, drag initiation, and entering/exiting targets. The actors involved include objects, cursors, and containers. Finally, it describes using drag and drop for rearranging modules, lists, changing object relationships, and invoking actions.

This document discusses HCI (human-computer interaction) in the software development process. It explains that HCI is used to create an intuitive interface between users and products. Usability, effectiveness, efficiency, and satisfaction are important traditional usability categories to consider. The software lifecycle involves designing for usability at all stages. Prototyping is discussed as a model where prototypes are built, tested, and refined with user feedback until an acceptable final system is achieved. Design involves understanding users, requirements, and balancing goals within technical constraints.

This document discusses various cognitive processes involved in human-computer interaction such as attention, perception, memory, learning, and problem-solving. It explains how an understanding of cognition can help design better interactive products by accounting for cognitive limitations and identifying usability issues. Specific topics covered include the effects of multitasking on attention, the differences between recognition and recall memory, and the importance of context for memory. Design implications discussed are structuring information to capture attention, enabling recognition over recall, and providing memory aids.

This document provides an overview of human-computer interaction (HCI) as an academic discipline and design field. It discusses what students will learn, including understanding systems and humans through analysis, and applying that understanding to design solutions with a focus on real users. It outlines topic areas like design processes, underlying theories of human cognition, and specific domains. It also explores the roots of HCI in fields like psychology and computing. Finally, it discusses changes in the field with increasing device multiplicity, ubiquitous and wearable technologies, and a shift from computer dialogue to dialogue with the world.

This document discusses models of interaction between humans and computers. It describes Norman's model of the execution-evaluation cycle, which outlines 7 stages of interaction: establishing a goal, forming an intention, specifying actions, executing actions, perceiving the system state, interpreting the state, and evaluating it. It also discusses Abowd and Beale's interaction framework, which includes the system, user, input, and output as components and how there are translations between them. Key concepts discussed include the gulfs of execution and evaluation, different interaction styles, and how interface design can help reduce errors.

Usability: the extent to which a product can be used by specified users to achieve specified goals with effectiveness, efficiency and satisfaction in a specified context of use.“ For instance: • Appropriate for a purpose • Comprehensible, usable, (learnable), … • Ergonomic, high-performance, ... • Reliable, robust, …

The document discusses various input and output devices used in computer systems. It describes keyboards, mice, touchscreens, displays, printers and scanners. It explains how these devices work and how they allow interaction with computers. Different interaction techniques are suitable depending on the devices used, such as direct interaction with touchscreens versus indirect interaction with mice.

Human Computer Interaction was developed in 1983 by Stuart Card, Thomas Moran, and Allen Newell and explained in their book "The Psychology of Human Computer Interaction". It uses goals, operators, methods, and selections to model and predict human performance on computer systems. Goals are what a user wants to accomplish, operators are actions to reach goals, methods are sequences of operators, and selections determine which method to use based on context.

This document discusses various aspects of user interface design, including graphical user interfaces, interaction styles, information presentation, error messages, help systems, and user documentation. It provides descriptions and comparisons of different interface design approaches such as direct manipulation, menus, forms, command languages, and natural language interfaces. It also outlines principles for user-centered design and guidelines for effective user interface design.

This document discusses input and output channels in human-computer interaction. It describes the five human senses - sight, hearing, touch, taste and smell - and how they provide input. It then discusses the major effectors like limbs, fingers and vocal systems that provide human output. The document focuses on how vision, hearing and touch are used as input channels in interacting with computers, primarily through the eyes, fingers and voice. It provides details on the physiological mechanisms and processing involved in each sense.

This document discusses human-computer interaction and interaction models. It begins by outlining the learning objectives, which are to understand basics of interaction, differentiate between interaction models and styles, and understand the impact of interaction in social and organizational contexts. It then defines interaction and discusses several interaction models and styles, including command line interfaces, menus, natural language, forms, spreadsheets, and WIMP (windows, icons, menus, pointers) interfaces. It also covers physical aspects of interfaces like ergonomics and different interaction contexts.

1. Interaction design focuses on meaningful communication between people and technology through collaborative processes. It includes interaction models, ergonomics, interaction styles, and context. 2. Models of interaction help understand what is occurring in the interaction, identify difficulties, and compare styles. Norman's model describes the execution-evaluation cycle, while Abowd and Beale's framework has four parts: user input, system, output, and context. 3. Common interaction styles include command-line, menu-based, natural language, form-fills, point-and-click, 3D, and question/answer interfaces. The widespread WIMP interface uses windows, icons, menus, and pointers.

The document discusses principles of user interface design including interaction styles, information presentation, user support, and evaluation.
