What is the interactioN?
Using a coin phone
What is the experience?
OBSERVATIONS
Coin (Public) phone
- Public phones are designed to be used by the general public
- Insert money and key in the phone number
- If engaged or unable to connect the money is returned when the receiver is replaced
- Money gets inside the box if phone gets connected
- Insert more money to extend the call
- Many have Braille embossed on the keys

WHAT IS THE INTERACTION?
Using a cell phone
What is the experience?
OBSERVATIONS
Cell (Touch) phone
- Intended for PERSONAL USE
- Complex functionality
- Steep learning curve
- Save frquently dialled numbers, Use hot keys to call
- Lots of nuisance value
- No support for visually impaired...unless speech recognition works

Process of interaction design
1. Identifying needs and establishing requirements
2. Developing alternative designs that meet those requirements.
3. Building interactive versions of the designs so that they can be communicated and assessed.
4. Evaluating what is being built throughout the process
Understanding problem space
Asking the users if the product will address their problems
Getting feedback
Knowing the details of the problems they have
Understanding the problem
Example: Problems carpenters face with a measuring tape
Understanding the problem
Example: Problems with a measuring tape
Version 1 Version 2
Think - Pair - Share

What interaction is added?
Tape with marking facility!
What interaction is added?
Digital tape
What interaction is added?
Digital measuring tape with laser beam and a display
More advanced?
How has our navigation evolved?
Refer Maps
Ask people
Remember landmarks
Make Calls
Sign boards

Kiosks
You are here.
But where is this place?
How has our navigation evolved?
What has changed in this interaction?
Where is this going?

Conceptual models
Description of the system in terms of
-
set of integrated ideas
-
what should it do, behave, and look like
This description should be understandable by the users
in an intended manner
in an intended manner
Conceptual models
Two main types:
-
based on activities
-
based on objects
CONCEPTUAL MODELS
based on Activities
-
Instructing
-
Conversing
-
Manipulating and navigating
-
Exploring and browsing
CONCEPTUAL MODEL: Instructing
Accessing the information/getting the result
by instructing the system
Examples
Issue instruction to the system to perform a task (Print a page)
Reminder for appointments (Wake me up at 6:30 AM)
Preferable for repetitive tasks

Reminder for appointments (Wake me up at 6:30 AM)
Preferable for repetitive tasks
CONCEPTUAL MODEL: Conversing
Converse with the system to get information/result
Examples
Train time inquiry system
Search engines
Train time inquiry system
Search engines
Preferable when user needs specific kind of information
CONCEPTUAL MODEL:
Manipulating and Navigating
Navigate within the system using the knowledge of the user about the objects in physical world
Examples
Computer Desktop screen
Solitare card game
Physical action of button pressing instead of giving
command/asking a query (complex syntax)

CONCEPTUAL MODEL:
Browsing and Exploring
Search, browse, and find different kind of information

CONCEPTUAL MODELS
based on Objects
Focus is on the way a particular object is used
in a specific context
Example: Ledger for recording data
