LESSON 1

• Human-Computer Interaction Subject Code


  COMP 013
• Course Instructor

  Bryan Lawrence T. Asistin
• a cross-diciplinary area that deals with theory, design, implementation, and evaluation of the ways that humans use and interact with computing devices

  Human-Computer Interaction
• HCI uses _ to support and fulfill human-computer activities

  productivity, safety, and entertainment
• HCI initially focuses on _

  computer interface design
• an individual user, a group of users working toger

  User
• any technology ranging from desktop computers, to larger scale computer systems

  Computer
• the design of a website, mobile phones, or VCR can also be _

  computers
• There are difference in computer and human. To achieve a usable systems, you need to apply what you know about humans and computers and consult with likely users throughout the design process

  Interaction
• Aside from making the necessary computational functionalities available, HCI focus has been on how to design and implement computer interfaces for _ and _

  high usability and user experience
• the resulting interfaces are easy to user, efficient for the task, ensure safety, and lead to a correct completion of the task

  High Usability
• a notion that not only encompasses the functional completeness, high usability, and the aesthetic appeal of the interactive artifact, but also its seamless intergration into one's lifestyles or even creating a new one around it

  User experience
• Why we shift from applications to web app?

  because of storage, and cross platform
• why people disregard manuals?

  because gadgets can speak for it self because of UI AND UX
• early focus of HCI

  how to design interaction and implement interfaces for high usability
• interaction is difference from

  interface
• Bad Design can cost

  lives, money and time
• visual, look and presentation. it does help you have good user experience

  user interface
• analytical. improving accessibility. how user will feel better using that service or product? strategy and content, analysis. whta structure is best to absorb content by users

  user experience
• multidisciplinary field of HCI

  computer science, human factor engineering, cognitive science
• interaction between a computer and the user should resemble a _

  human to human, open-ended dialogue
• founder of the field of human computer interaction

  John M. Carroll
• _ while satisfying the need for usability is now a critical requirement for commercial success

  simple aesthetic appeal of an interface
• importance of HCI

  high output and aesthetic appeal
• Principles of HCI serves as the backbone of designing interactive interfaces


  Know thy user, understand the task, reduce memory load, strive for consistency, remind users and refresh their memory, prevent errors/ reversal of action, natural interactions and interface
• HCI design needs to consider _

  types of user, characteristics of the taskm capabilities and cost of the devices, lack of objevtive or exact quantitative evaluation measures, and changing technologies
• the interaction and interface should cater to the needs and capabilities of the target user of the system in design

  know thy user
• _ (age, gender, education level, social status, computing experience, cultural background) about the target user should be collected and analyzed to determine their probable preferences, tendencies, capabilities and skill levels

  comprehensive information
• identifying the sequence and structure of subtasks at an abstraction level appropriate for the typical user within the larger application context

  understand the task
• refers to the job to be accomplished by the user using the interactive system

  task
• humans are more efficient in carrying out tasks that require less memory burden, long or short term

  reduce memory load
• the capacity of the human's short-term memory(stm) is about 5-9 chunks of information, aka _

  magic number
• applies to both interaction model and interface implementation . ex: consistent look of the interface within a gaming application

  strive for consistency
• employ interfaces that give continuous reminders of important information and thereby refresh the user's memory

  remind users and refresh their memory
• interaction and interface should be designedd to avoid confusion and mental overload

  prevent errors/ reversal of action
• a perfect hci may one day be realized when a natural language - based conversational interface is possible, because this is the prevalent way that humans communicate

  natural interaction and interface
