JMA 464/545 - Purpose

• Introductory course about IxD & HCI

• Overview of IxD, HCI, UX, and usability

• Review IxD, HCI, UX methods and issues

JMA 464/545 – Course goals

• Develop understanding of IxD, human computer-interaction (HCI) and user-centered design & development.

• Develop understanding of UX, user-experience practices.

• Discuss development processes and tools.

JMA 464/545 – Course goals

• Explain methods for IxD research & development.

• Demonstrate general principles underlying effective interaction design and navigation control.

• Use equipment and software to observe interaction.

JMA 464/545 – Applications & Tools

The course focuses on:

1)Interaction/HCI

2)User observation

3)Design & Development based on observation/study.

JMA 464/545 – Applications & Tools

• In class we use a variety of tools to prototype interactions.

JMA 464/545 – Applications & Tools

For observations, we will use:

• Observer XT

• Arrington Research Eye-tracker

• TechSmith – Morae

• Human Factors Facility

BEGIN TO OBSERVE EVERYDAY THINGS……how might you improve them?

Is the coffee maker on or off?

How do you fix it?

Returns Web-wide results, which confuses users

CNN now implements search in this way.

Mapping. Good or Bad?

A B C D

Is this a better design?

Mapping – direct relationship between the device design and its functionality.

Poor designs?

People often take the path of least resistance.

Try to figure out what the least resistant paths are before pouring concrete.

People often take the path of least resistance. In a similar way, Amazon makes it easy to buy additional items.

People want information, services, entertainment… Your design should accommodate their needs as efficiently and effectively as possible.

Sometimes constraint is not visible.

Task: Return movie (DVD) to Redbox

I think… similar to

Task: Return movie (DVD) to Redbox

Ok, drop it in … but

Task: Return movie (DVD) to Redbox

Must press Return A DVD first

What might be a better approach?

Task: Return movie (DVD) to Redbox

Why not a physical constraint instead of this? Return a DVD is activated when inserting DVD.

Labels???

If the switch is pointing to "Off", it's really "On", and vice versa.

Source: http://goodexperience.com/tib/b/product_design/

Labels???

The arrows relate to direction, not the final state of the switch.

The words “ON/OFF” suggest the final state but they are positioned inversely to switch function.

Source: http://goodexperience.com/tib/b/product_design/

Direction, not state of control

Labels???

A simpler design is better.

The switch affords/suggests how to use it.

Additional labels may add confusing information.

How do we design for different devices?• By looking at examples in the physical world, we can

become informed about how to design for:

• Web• Mobile devices• Etc.

We’re use to this…

What about this…

What about this…

What do these controls mean?

And the controls…

Design and use | Questions• How do people use different devices?• What can observing their use tell us about how we should

design and develop?• How do different devices influence behavior?

Design and use | Questions• How do we design for the initial User Experience (UX)?• How do we design for the entire User Experience (UX)?

Observe human-computer interactions

Example 5: Florida State Example 6: EyeTrackExample 4:Post

Example 7: CNN - EyeTrack Example 8: Student EyeTracks

Example 9: ViewPoint Analysis

DEFINITIONSHCI

Defining the field• …a discipline concerned with the design, evaluation and

implementation of interactive computing systems for human use and with major phenomena surrounding them.

• As defined by the Special Interest Group on Human-Computer Interaction (SIGCHI) of the Association for Computing Machinery (ACM)

Defining the field• Human-Computer Interaction (HCI) is the study and the practice of usability.

• …understanding and creating software and other technologies that people will want to use, will be able to use, and will find effective when used.

John Carroll, 2001

Defining the field• Rough characterization of HCI as a field. It examines:

• joint performance of tasks by humans and machines; • structure of communication between human and machine; • human capabilities to use machines (including the learnability of

interfaces); • algorithms and programming of the interface itself;• engineering concerns that arise in designing and building

interfaces; • process of specification, design, and implementation and

evaluation of interfaces; and design trade-offs.

• HCI has science, engineering, and design aspects.

User Name and Password• 8 characters or more• 1 UPPERCASE character• 1 number• 1 Special character ($, &) – no spaces

Our Server

www.jma.duq.edu• Your private folder• It’s a subfolder of users folder

• www.jma.duq.edu/users/YourLoginName

• Save files (drag and drop files) while in either lab (CH205, CH345)

• You can also FTP to there from home…

How do I access the server?• Access from either CH345 and CH205

• Start >> Computer (Z: Drive)

• \\jma1\users\username

• While in class, feel free to save to the net folder

How do I access the server?

From dorm or home

ftp://www.jma.duq.edu/users/YourLastName

• Example: ftp://www.jma.duq.edu/users/gibbs/

• You will be prompted for your user name and password• Use the same name and password you used to login to

Windows

How do I access the server?

You will be prompted for your user name and password – jma/username

How do I access the server?

• Folders and files display• Transfer (put) files from your computer, • Download (get) files to your computer.

How do I access the server?

• Your folder on server has a child folder named pub• Inside that folder you should create a folder for each

course that requires a web site• In this course, create a sub folder named JMA464

The PUB folder

•You might create subfolders, for each course.

Double-click on pub

Right-click on any unused white area

The PUB folder• Create new folder

• Name it your course name

Web URL• The URL to your website(s) depend on how you structured your home

folder• Using earlier example

http://www.jma.duq.edu/users/gibbs/pub/JMA464/FileName.htm

• Assuming your file name is default.htm, or index.htm in the jma464 folder the address would be:

http://www.jma.duq.edu/users/gibbs/pub/jma464/index.htm
