This book serves as a foundation to the field of HCI, equipping readers with the necessary knowledge and skills to engage in this field.
Human?Computer Interaction (HCI) is a multidisciplinary field exhibiting increasing significance in the modern world, shaping our interactions with technology and transforming our daily lives. HCI plays a critical role in bridging the gap between human capabilities and technological breakthroughs. As technology becomes progressively intertwined with our daily lives, it plays a significant role in enhancing human interaction with advanced information technologies.
This book serves as a foundation for the field of HCI. It covers the historical background, contributing disciplines, essential concepts and theories within the domain. This book also delves into human functionalities and characteristics relevant to interaction, including sensory perception, attention and memory, language and communication, emotions, decision?making, as well as mental models, human error, and human actions. Additionally, it explores the evolution of HCI design approaches and the role of social and organizational psychology in HCI, it discusses the key HCI concept of user acceptance of interactive technologies and addresses societal aspects such as ethics, privacy, and trust.
Moving forward to the realization of interaction, traditional techniques provide users with foundational methods for engaging with computers and digital systems. These techniques have adapted and endured, shaping user experiences and catering to evolving technological landscapes. Keyboard input, a versatile mainstay, allows efficient text entry and commands, especially valuable for programming and command?line interfaces (CLIs). The mouse, in tandem with Graphical User Interfaces (GUIs), revolutionized navigation through pointing, clicking, and dragging. Touch input, introduced with touchscreen devices, offers a direct and intuitive interaction with content. Menu?based interfaces create structured hierarchies for accessing functions and information, while CLIs remain a powerful choice for experts who value precision. Buttons and icons in GUIs serve as intuitive visual cues for interacting with software. Scrollbars facilitate content navigation, checkboxes, and radio buttons enable selection and setting choices, and dropdown lists simplify user decisions. Text fields are versatile for text and data input, while dialog boxes manage messages and user input effectively. Hyperlinks empower seamless web navigation. Drag?and?drop actions streamline tasks like file management.
These traditional techniques, alongside contemporary approaches, compose the toolkit for user engagement in HCI, ensuring a rich and multifaceted interaction landscape that continues to adapt to the ever?changing digital world. While emerging technologies and novel methods continually enrich the HCI domain, these well?established traditional techniques retain their significance in modern computing. Yet, the integration of contemporary approaches progressively enhances the user experience, delivering a holistic and intuitive interaction framework for users engaging with computers and digital systems.
Gestures provide natural and intuitive ways for users to interact with computer systems. They leverage users’ ability to convey intentions and manipulate objects through bodily movements. Proper user interface and interaction design are essential for devices, applications, and systems that detect, recognize, and interpret gestures accurately. Various gesture taxonomies contribute to interactions with computer systems, drawing from research in motor control, psycholinguistics, and HCI. The adoption of gestures is motivated by their deep connection to language and their effectiveness in conveying information and facilitating interactions, making them increasingly relevant in touchscreens, mobile devices, wearables, and immersive environments.
Voice user interfaces (VUI) enable users to interact with technology using spoken language or vocal commands, but present distinct challenges due to their reliance on audio interactions without visual displays. These interfaces rely on speech recognition, synthetic speech production, and dialog management technologies to guide users efficiently through tasks. When considering voice interaction in an application, it is vital to analyze user capabilities, task requirements, and motivations. VUIs are suitable for scenarios where auditory acuity is primary, but designers should avoid them in contexts where noise, hearing?impaired users, or other limitations pose challenges.
Wearable technologies encompass devices worn on or within the user’s body, ranging from smart clothing and accessories to implanted devices. These wearables provide information or operate as closed?loop systems. Usability is critical for wearable acceptance, considering customization, accuracy, and comfort. Privacy concerns and impacts on social interactions should also be considered. Wearables have applications in various fields, from healthcare and education to manufacturing.
