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

Understanding the problem

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?




Bagel smart tape measure

How has our navigation evolved?


Refer Maps
Ask people
Remember landmarks
Make Calls
Sign boards
----------------------------------------------------
Kiosks
Mobile apps

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

Conceptual models




Two main types:
  • based on activities
  • based on objects

CONCEPTUAL MODELS
based on Activities 




  1. Instructing
  2. Conversing
  3. Manipulating and navigating
  4. 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

CONCEPTUAL MODEL: Conversing

Converse with the system to get information/result 



Examples
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


Examples
Train time inquiry system
Search engines


Preferable when user needs specific 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

CONCEPTUAL MODELS 
based on Objects

Focus is on the way a particular object is used 
in a specific context

Example: Ledger for recording data

CONCEPTUAL MODELS 
based on Objects

Focus is on the way a particular object is used 
in a specific context
Example: Ledger for recording data: SPREADSHEETs
