HCI 1.1 & 1.2

• Human. The end-user of a program
• Human. Engages with technology to accomplish tasks or access information.
• Human. Provides input to the computer through various interaction
• Computer. The machine on which the program runs.
• Computer. Processes and executes instructions provided by the user or the or the

  program itself.
• Computer. Generates output or results based on the user's input.
• Interaction. The dynamic process where the user communicates their intentions
• Interaction. Involves the user telling the computer what they want to achieve or obtain.
• Interaction. Includes the computer's communication of results, feedback, or information back to the user.
• Human-computer interaction is a discipline concerned with the design, evaluation and implementation of interactive computing systems for human use and with the study of major phenomena surrounding them.
• Human computer interaction It is a multidisciplinary field that focuses on the design and use of computer technology, with an emphasis on the interfaces

  between people (users) and computers
• HCI studies human performance in the use of computer and information systems to make interaction between them more effective and more enjoyable.
• Humans are limited in their capacity to
• Visual Channel (Watching a movie, reading and observation)
• Auditory Channel (Listening, Attending a live concert, Conversation)
• Haptic Channel (Feeling texture, Sensing weight and Touching)
• Movement ( Expressing emotions through body language)
• -Sensory Memory ( Visual Memory , Auditory Memory, Haptic

  Memory)
• -Working Memory (Short Term Memory)
• -Long-Term Memory ( Remembering Facts, Concepts, General

  Knowledge)
• Computer A programmable usually electronic device that can store, retrieve, and process data
• Computer consist of

  -Input Devices

  -Output Devices

  -Memory

  -Processing
• Computer can be Mobile, Spacecraft Cockpit, Microwave Oven or VCRs etc.
• HCI is concerned with joint performance

  of Task by Human & Computer
• Communication between The User and

  The System. Physical Interaction. Conceptual Interaction
• Physical Interaction

  Interaction Devices
• Interaction Devices are tools or

  hardware components that facilitate

  communication and input between users

  and computers.
• Interaction Devices Ex: Mouse, Keyboard, Game Controller
• Conceptual Interaction

  Interaction Styles
• Interaction Styles refer to the ways

  users interact with computer systems and

  software applications.
• Interaction Styles Ex: Command Line, Menu-Driven, GUI
• Interaction device: is the device where the user can receive

  position, localization, navigation instructions, etc., and interact

  with the information.
• It can be a specific dedicated device, a

  computer, a tablet, or, more commonly, a smartphone. Interaction device:
• It is

  something that the user takes with himself or herself. Interaction device:
• Interaction Styles refers to all the ways the user can

  communicate or otherwise interact with the computer system.
• The concept belongs in the realm of HCI or at least have its roots in

  the computer medium, usually in the form of a workstation or a

  desktop computer. Interaction Styles
• Key Components of HCI. The user, The goal-oriented task, The interface, The context
• The user component refers to an individual or a group of individuals

  that participate in a common task.
• HCI studies users’ needs, goals, and

  interaction patterns.
• A user operates a computer system with an objective or goal in mind. The goal-oriented task
