JMA 464/545 - Purpose

• Course about IxD & HCI

• Overview of IxD, HCI, UxD, and usability

• Review IxD, HCI, UxD methods and issues

JMA 464/545 – Course goals

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

• Develop understanding of UxD, user-experience design.

• 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

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?

What might happen?

What might happen?

Pull hood latch

Proximity

What might happen?

What might happen?

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 example – digital interface• You’ve been asked to develop App that controls electrical

outlets in a home or building.

Could organize like this- Menu driven

Could organize spatially – direct relationship between outlet location and

interface

Mapping – direct relationship between the device design and how it functions.

Poor designs?

• Which bottle ?- Insulin

Not sure what these mean? Cadillac car What do you think happens?

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.

Logical constraint

Task: Return movie (DVD) to Redbox

I think… similar to

Conceptual model

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 or how to use switch, not the final state of the switch.

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

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)?
