Human Computer Interaction
Definition: Human computer interaction researches the design and use to focused on interfaces between people and computers. Researchers in the field of HCI both observes the way in which human interact with computers and design technologies that’s let humans to interact with computers in novel ways.
Goals of HCI:
- Understand the factor that determine how people use technology
- Develop tools and techniques to enable building suitable system.
- Achieve efficient, effective and safe interaction.
- Put people first.
-Input and Output Channels of Humans:
- Vision
- Hearing
- Touch
- Movement
- Vision: visual perception perceiving size and depth , perceiving brightness , perceiving colors and read. Function of eye.
- Hearing: the human ear outer, inner middle processes sound frequencies from about 20Hz to 15KHz sound perceiving.
- Touch: haplic perception. 3 sensory receptor Thermoreceptor (respond to head and cold) Nociceptor (respond to intense pressure heat and pain) Mechanoreceptor (respond to pressure).
- Movement: the act or process of moving people or things from one place or position to another.
Human memory: complex brain wide process. Types of human memory register, short term memory, long term memory.
- Sensory memory: it is automatic response that can observe and memorize a perceive item.
- Short term memory: can temporarily store and retrieve information for 10 seconds to one minute .
- Long term memory: stores and retrieve information for long period of time.
Thinking: The process of considering and reasoning about something.
Reasoning and problem solving:
- Reasoning: The action of thinking about something in a logical and sensible way.
- Problem solving: The process of finding solution to difficult or complex issues.
● Gestalt (or form) theory: We are pre-programmed to perceive forms that we use constantly to understand our environment, by grouping and restructuring them to solve the new problems.
● Analogy: The analogy is used to solve a new problem by looking for similitudes with known situations and events, for which the problem was solved.
Emotions: A strong feeling deriving from one’s circumtances , mood or relationships with others.
Individual differences: Individual difference psychology examines how people are similar and how they differ in their thinking, feeling and behavior.
That people differ from each other is obvious how and why they differ is less clear and is the subject of the study of individual.
