Lecture 1: HCI - Human Computer Interaction

Human Computer Interaction

is a cross-disciplinary area (e.g., engineering, psychology, ergonomics, design) that deals with the theory, design, implementation, and evaluation of the ways that humans use and interact with computing devices.

Interdisciplinary of HCI

• Artificial Intelligence

• Engineering

• Computer Science

• Psychology

• Neuroscience

• Sociology

Three (3) Components of HCI:

Purpose of HCI:

• Simple

• Accesible

• Useful

Importance of HCI:

• Value

• Sensitive

• Design

The distinguishing concepts of interaction (model) and interface

Examples of Interface:

• Gesture Interface

• Gaze Systems

• Voice Recognition

• Haptics Technologies

• Augmented Reality

Goals of HCI:

• Take pictures/videos

• Edit pictures/videos

• Share pictures/videos

• Manage pictures/videos

• Voice activation

User Experience (UX)

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

A user’s experience is just the tip of the iceberg:

Many people mistakenly think that “UX” means a user’s experience, but it is actually about “doing” the process of User Experience Design. A user’s individual experience is their conscious, subjective opinion of your app or site. User feedback is important—sometimes—but UX designers need to do a lot more than that.

The Variety of UX

UX

____ concerned with many different types of interactive service and product.

UX

It is about designing web services that will run on a computer at work.

UX

It is about designing apps, games, interactive products such as home control systems, digital cameras and applications for tablet devices such as the iPad.

UX

It is about designing whole environments, such as new retail spaces, in which phones, tablets, laptop computers, digital projectors and other devices and services communicate with each other and through which people interact.

UX

It is about designing user experience, products and services for the home, for work or to support communities.

Some examples of influential interactive products, services and systems:

• iPhone

• Nest Home control

• Burberry

• iRobo-Q domestic toy robot

• Facebook

Device Ecologies

UX is often experienced through an ecology of devices rather than on a single device.

Ecology

where a number of different organisms (or devices in this case) work together to create an environment.

UX

__ is increasingly concerned with interactions that involve a number of different devices: a device ecology.

Product Design

Sometimes designers will be working on both the hardware and the software for a system, in which case the term ‘____’ seems to be most appropriate to describe what they are doing.

System Design

Sometimes the designer will be producing a piece of software to run on a computer, on a programmable device or over the internet. In these cases the terms ‘____’ or ‘designing user experience’ seen more appropriate.

Case Service

Sometimes the designer will be working on providing a connected group of facilities that is available over a number of devices, which case _____ is most appropriate.

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

• Design

• Technologies

• People

• Activities and Contexts

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

• Useful

• Usable

• Findable

• Credible

• Desirable

• Accessible

• Valuable
