Human Computer Interaction (HCI)

a cross- disciplinary area that deals with the theory, design, implementation, and evaluation of the ways that humans use and interact with computing devices.

Human
Computer
Interaction

Three components of HCI:

Human to Computer: Action language (Input)
Computer to Human: Presentation language (Output)

Communication Cycle in HCI:

Human

The end-user or group of users interacting with a technology system to perform tasks

Computer

The hardware and software system that receives inputs, processes data, and provides output.

Interaction

The two-way dialogue and feedback loop between the user and the system.

Action Language

The inputs and commands sent from the human to the computer (e.g., clicks, typing, gestures).

Presentation Language

The output and visual feedback provided by the computer to the human (e.g., UI display, sounds).

Importance of HCI:

Share Pictures/Videos
Manage Pictures/Videos
Voice Activation

Goals of HCI:

User experience

Encompasses all the feelings, thoughts, sensations and actions of engaging in some activity.

doing the process of user experience design

UX does not simply mean “a user’s experience” but it is actually about _________.

Variety of UX

This says that UX is concerned with many different types of interactive service and products.

iPhone
Nest Home control
Burberry
iRobo-Q domestic toy robot
Facebook

Influential interactive products, services, and systems:

an ecology; single

UX is often experienced through ______ of devices rather than on a

_____ device.

Ecology

This is where a number of different organisms (or

devices in this case) work together to create an environment.

Device Ecology

UX is increasingly concerned with interactions that involve a number of different devices

Design
Technologies
People
Activities and Contexts

Key concerns of the UX designer may be summed up as follows:

Useful
Accessible
Usable
Valuable
Desirable
Findable
Credible

According to Peter Morville, the seven (7) factors that influence UX are:
