Lab 2:
Topic: GOMS
Scenerio:
You are required to edit an article. Analyze the situation and find out GOMS (Goal, Operators, Method,
Selection rule) for that particular scenario.
Students and teacher communicate through Skype/Adobe Connect
Solution:
• Goal: Edit an article
• Operators
 Use arrow keys
 Use mouse
 Use other keys
• Method: Delete text (sub-goal)
 Positioning:
1) arrow key
2) mouse
 Marking:
1) double click
2) use mouse
 Delete (and add text):
1) start writing
2) press delete, then write new text
• Selection rules: If close, use arrow key etc.

Lab 3:
Topic: Color Guidelines
Scenario:
In the figure below there are four colored backgrounds B1- B4 and four colored texts T1- T4.
Using color guidelines for color readability (using color brightness and color difference) find the text-
background pairs from below for best color text readability.
B1 B2
HAPPY (T1) HAPPY (T2)
B3 B4
Happy (T3) HAPPY (T4)

Solution:

Lab 4:
Topic: Stages of Action
Scenario:
I might want a place where I can relax outside that won’t get muddy and that I don’t have to move my
outdoor furniture around to mow.
What are the stages of action?
How the stages of action will be applicable on this scenario to achieve the goal?
Solution:
Stage 1 is Forming a Goal. This is what you want. As an example, I might want a place that I can relax outside
that won’t get muddy and that I don’t have to move my outdoor furniture around to mow.
Stage 2 is Forming the Intention. This is what would satisfy the goal. A deck would satisfy my goal of place to
relax outdoors that won’t get muddy or be in the way of mowing.
Stage 3 is Specifying an Action. What do I have to do to achieve the intention? I would need to build a deck to
meet the requirement set in my goal.
Stage 4 is Executing the Action. Here I would do the steps of the action. I would build the deck.
Stage 5 is Perceiving the State of the World. Using the senses to gather information. My finished deck would
be off the ground and have my outdoor furniture on it.
Stage 6 is Interpreting the State of the World. What has changed? My furniture is off the ground away from
the mud and no longer has to be moved to mow the lawn.
Stage 7 is Evaluating the Outcome. Did I achieve my goal? I can relax outdoors now without worrying about
mud or moving furniture. I achieved my goal

Lab 5:
Topic: Menus
Question:
 Why menus are used in the websites?
 Compare the different types of menus used in different websites (provide screenshots of the
menus). What are the advantages and drawbacks of those menus?
 Design a menu for an app that helps the user in finding the timing of the Prayers and the direction
of Qibla.
Solution:
Navigation is an important part of your design that helps users to get to the website sections they need.
Menus are used for this purpose.
Types:
1) Horizontal menu
Screen Shots:
Advantages:
i) Horizontal Menu is good for usability. Users clearly see which section they are currently
looking at.
Disadvantages:
i) The drawback of horizontal menu is that the number of links they can contain is pretty limited.
2) Vertical Menu

Screenshots:
Advantages:
i) Vertical Menus are used for article and blog site where each article corresponds to its
description on its right side.
Disadvantages:
i) Vertical menus have more space for links, sometimes they tend to become hard to look
through.
3) Dropdown Menu:

Screenshots:
Advantages:
i) Drop-down menus are good for websites with complex structure. Online shops with a wide
range of goods and a lot of product groups. With them you can hide subsections and keep the
precious space uncluttered.
Disadvantages:
i) This type of menu has a drawback though — it can be too hard to notice. That’s why it is used
for data of secondary importance. Nonetheless, designer has to make it visible enough to a
user.

Part 3:
Design menu for an app.

Students will use paint, corel draw or any other tool for designing the menu.

Lab 6:
Topic: Prototyping
Question:
You have to design a prototype for an application.
Application’s goal is “to help the people to find out the timing of Prayers and the direction of the Qibla”.
Note: You do not need to prototype “How to Pray” and “Zakat Counter” functionalities.
Solution:

Students will use paint, corel draw or any other tool for prototyping design.

Lab 9:
Topic: Design Principles (Norman)
Question:
Identify one example of a good designed and one example of a badly designed handheld device, e.g.
remote control, hand phone, hard phone, digital camera, calculator etc.
Use your intuition and Norman’s design principles: mapping, visibility, feedback, consistency, constraints
and affordances to do the following evaluations:
 For the good designed device: state what is good about the design and why you find it well
designed (e.g., show how does it follow Norman’s “feedback” principle)
 For the badly designed device: state what the problem is and why you find it to be a problem (i.e.,
what difficulties, misunderstandings does it cause).
 In both cases, support your argument by using at least two (2) of Norman’s design principles.
Explain how these principles are met or violated by the devices you have chosen.
Solution
Bad Design Device: Remote control
Intuition about design: The basic purpose for the remote is just to change the channels, tuning, volume,
display and audio settings but recently TV remote controls have lots of buttons and no one knows that
what is their working actually. They are controlling DVD and CD Players and many others. That makes it
complex.
Norman’s design principles:
Visibility: A TV remote is showing all the operations it can perform with a better sectioning in a good
arrangement. Each function can be seen on the remote, but all the functions which are needed and which
are needed rarely, it makes your deign a bit complex and difficult for a naïve user to understand.
Feedback: In a TV remote, it’s easy to get feedback, as whatever you are doing it is performed on the
screen. But in the case of AC remotes, sometimes, you press a button and AC can’t accept it due to missing
signal. On AC remote screen, that task is done, but the AC didn’t accepted that command. There’s a slight
problem with the feedback of the AC and AC remote.

Affordance: Affordance problem exists with the remotes, sometimes what you perceive is actually not
the actual operation. As the image above, here someone can perceive that these upper and lower arrows
are for the channels and left and right arrows are for volume, as some remotes follow this structure.
Note: it does not give any option to undo your last action.
Good Design Device: Hard phone
No problem with the interface with respect to my intuition.
Norman’s design principles:
Visibility: Hard phone has a limited set of operations and buttons on it. Each button is visible with its
operation on it. If user presses button 5 then it appears in the display section and same is the case with
other buttons. Hard phone satisfies visibility principle.
Feedback: Hard phone holds the principle of feedback. Whatever you do on your hard phone it gives
response either on its screen or by using a dial beep.
Affordance: Each of the buttons defines its purpose by a symbol. For example, Speaker button has a
Speaker symbol on it same is the case with hold button. Hard phone has a well-defined interface satisfying
affordance.

Lab 10:
Topic: Heuristic Evaluation
In this Lab, you will be given
Task List of Five mobile applications: Calendar, Skype, Gallery, Amazon, and CNN
Solution Table: Which you should fill up after task performance.
Heuristic List Table: This table will help you to solve assignment.
Assignment Execution:

Understanding the below given tasks list
Understand and read “Heuristic list” with examples given at the end
Understanding of “Heuristic/Guideline List Table”
Understanding of basic HCI, Usability, cognitive modeling, Interaction paradigm and mobile paradigm
related concepts
Procedure:
1-Pick up first application (calendar),
2- Execute task 1.1 on your smartphone while in motion/ doing some other task,
3-Observe interface behavior, brainstorming, think about any user related issue, if you find out usability
related flaw, write up.
4-Else perform again in moving environment/while doing some other task,
5- Go to step 3 (Observe behavior)
6- Now, if you still unable to find any flaw, take help from “Heuristic/ Guideline List Table” where you will
find “violations” in third column of table. See one by one and if you find one or more that represent your
observation.
7- Select these violations and look up corresponding heuristic number in the same table. Enter heuristic
number (only number) in 4th column of solution table. Also mention the violation in third column.
8- Keeping in view each violation nature, you are required to assign severity number of each usability
related flaw in 5th column
9- Write up reason of this assignment of severity number in 6th column
10- Write up environment in 7th column
11- Go to step 1 and repeat the whole procedure for task 1.2 of calendar application.
12- Go to link of Calendar Survey Form and fill up with the same values. Submit button
13- This 1-12 point procedure of usability evaluation will perform for Skype, Gallery, Amazon, and CNN.
Calendar
Task 1: Event creation
Task 1.1: Add an event in your calendar mobile application. Give values to different fields like select
date, place, add guests list etc. and finally save the event.
Task 1.2: Use “Reminders” to create and view to-dos alongside your event.

Skype:
Task 2: Send Message to group
 Task 2.1: Message your friends in an instant and add up to 3 people to a group chat.
 Task 2.2: File Transfer: Select a person, make a Skype call and during conversation, share a file.
Gallery:
Task 3: Search .
 Task 3.1: Search the specific picture using “filter by” (Events, people, scenery, food, pet etc) from
gallery application. Tap the picture you want to view and set as a wallpaper
Searching picture isn’t effective.
 Task 3.2 Select a picture or a video from Gallery and apply different basic operations like “copy to
album”, “move to album”, “rotate left”, “rotate right”, “add tag” etc.
Amazon Shopping: Hard to find, ergonomics in motion, error prevention mgt (no suggest solution at
signup), avoid misleading links (I asked for television, but here display DVD’s , restaurant but lamp, meal,
books) , user awareness about task steps
Task 4.1: Go to main page of Amazon, register yourself (sign up). Then, using your credentials to sign in
and select search by voice option, here are things you can do with voice like “search, reorder, add to cart,
track order etc. Do this task and observe behavior.
Task 4.2: Go to the shopping page, select few items to buy, add to cart. Then modify the order and finally
place the order (fill up desired fields without giving account detail and submit form) observe behavior.
CNN
Task 5: News Alert
Task 5.1: Open the app to scan the world’s top headlines. Explore interactive featured stories.
Task 5.2: Quickly catch up on International, Opinions, Entertainment and other CNN coverage. Watch CNN
TV live on your device
Summary:
Every expert t will perform each task in sitting as well as in moving/dynamic state.
The following 0 to 4 rating scale can be used to rate the severity of usability problems:
0 = I don't agree that this is a usability problem at all
1 = Cosmetic problem only: need not be fixed unless extra time is available on project

2 = Minor usability problem: fixing this should be given low priority
3 = Major usability problem: important to fix, so should be given high priority
4 = Usability catastrophe: imperative to fix this before product can be released

Joyce Method:
SMART6 (Aesthetic, pleasant, appealing)
Design a visually pleasing interface. Mobile interfaces that are attractive are far more memorable and are
therefore used more often. Users are also more forgiving of attractive interfaces.
SMART7 (Learnability)
Intuitive interfaces make for easier user journeys. Mobile interfaces should be easy-to-learn whereby
next steps are obvious. This allows users to more easily complete their tasks.
SMART8 (multiple usage of multi touch gesture, user control obviousness)
Design a clear navigable path to task completion. Users should be able to see right away how they can
interact with the application and navigate their way to task completion.
SMART9 (Allows Configuration Options)
Heuristic/Guideline list Table (Solution)
Heuristic Name Possible Violation
SMART4
User isn’t clear about the interface initially
about what to do to complete task
Don’t provide clue about what to do next for
task completion
I feel difficult to perform task while doing other
task in parallel
SMART5 I found an additional step while performing task
I feel design of interface don’t focus properly
only on user task
I feel this task can be accomplishedwithout any
specific requirement
A task consist of many pages/clicks, which is
difficult to continue while in motion

SMART2 Logo, words, phrases, concepts aren’t match
with real world scenario.
Contents and/ buttons aren’t properly
organized
SMART11 Control/object size doesn’t appropriate, feel
difficulty to access action, speed issue due to
less control over objects/button specially in
motion
SMART7  Demands some extra effort to
understand interface
SMART1
No feedback upon any action
SMART6  No pleasant view, irrelevant and
additional information
SMART10 I found no/less audio sound of by default ring
tone attached with reminder etc while in
motion and noisy situations like on the road.
SMART3 Displayed error message don’t diagnose
problem properly,
Error Message don’t suggest solution in an
appropriate manner
SMART8 Not Design a clear navigable path to task
completion
SMART9
System don’t provide shortcuts for expert users
to speed up
System don’t provide interaction for naïve users
SMART 12 NOT Use the camera, microphone and sensors
when appropriate to lessen the user’s
workload. Consider the use of the camera,
microphone and sensors to lessen the users’
workload. For instance, by using GPS so the user
knows where they are and how to get there
they need to go, or by using OCR and the
camera to digitally capture the information the
user needs to input, or by allowing use of the
microphone to input content.
