Assignment
Q1
Consider the Automatic Replies function in the Microsoft Outlook application, as shown in
the figure below. This is a function that allows users to set automatic replies to emails. For
example, if the user is on holiday, he could set up an automatic reply message to say that he
will not read emails until he returns from holiday.
The function is limited in how time is specified- it only allows the specification of one
continuous time frame, between a start time and end time, as shown in the picture.
A user may wish to post these replies on specific dates or on specific days of the week for a
certain period, or even on specific hours of working days, etc. This is currently not possible!
Instructions
Part 1: Task Analysis
(This task is worth 10 marks/20)
Redesign the Automatic Replies window to allow the user to specify an auto reply message
for weekdays and a message for weekends. (This task will be referred to as “set regular
week” use case)
• For weekdays, the automatic reply message will be active between 5:30 pm and
8:00am and should read “I am out of the office- working hours are between 8:00 and
5:30 Monday-Friday”.
• For weekends, the automatic reply message should read “I don’t work on weekendsworking hours are between 8:00 and 5:30 Monday-Friday”.
a) Produce a sketch of the redesigned window to fulfil the “set regular week” use casehand-drawn or a digital sketch is acceptable. Clearly annotate the design to explain
and justify the interface controls and features used in your design.
(7 marks: 4 marks for the design and 3 marks for the annotation/description)
b) Produce a State Transition Network (STN) to describe the interaction flow for the
basic flow scenario only of this use case.
(3 marks)
Note:
An interface state changes when an event occurs. For example, an entry of text in a text
field, a click of a button, etc. Your STN needs to depict all possible states and user actions
between states in the use case scenario.
Note: Your use case can assume that the user has Outlook opened successfully.
Part 2: Heuristic Evaluation
(This task is worth 10 marks/20)
Do a heuristic evaluation of the individual states of the interface that you identified in
the STN in part 1 above and identify all usability-related features and issues.
Report on usability in an objective manner and in a standard format using the template
(Excel spreadsheet) provided and discussed in the lectures. Your report should include,
a. the usability problems you identified with some justification of the severity score
assigned to the problems and your suggestions for addressing the issues you
identified in subsequent revisions of the interface, and
(5 marks)
b. the good design features that should be maintained in any subsequent revision of
the application.
(5 marks)
Report guidelines:
You need to use the HE spreadsheet template provided. Use one sheet in the spreadsheet
for every screen/state that you identified in the STN of part1 (b).

Q2
This question is divided into two parts. Parts I and II are completed individually. Part I
requires you to plan an experiment choosing from one of 3 problems. Part II involves
reporting and reflecting on your experience.
Part I: Experiment Design and Conduct
You are tasked with designing an experiment. Pick ONE of the following problems:
• Design an experiment to assess the impact of keyboard and touch screen-based text
entry on text input speed.
• Design a study to compare the usability of TWO different ecommerce user interfaces
for browsing and choosing fashion products.
• Design a study to compare player experience between any TWO games of your
choice.
It is your responsibility to design the experiment. You must carefully plan out your
experiment and choose appropriate and applicable research methods. Key considerations
you must make are: 1) what variables to manipulate and measure, 2) which instrument
(e.g., questionnaire) is appropriate, 3) if a between or within groups design is appropriate,
and 4) what confounding factors might design decisions introduce and how to mitigate
them. NB: You must NOT conduct your experiment with any participants and/or collect data
in any way. Doing so without prior ethical approval will result in a breach of the university’s
ethics policy for human research: https://intranet.cardiff.ac.uk/staff/supporting-yourwork/research-support/research-integrity-and-governance/research-ethics
Part II: The Report
Write a reflective report. You should detail your experiment design with appropriate critical
reflection. When writing your report, you MUST address the following questions as stated in
the template document. The marking scheme is as included in parentheses:
1. What is your null hypothesis and alternative hypothesis? (2 marks)
2. What are your IV(s) and what are your DV(s)? (2 marks)
3. Give a detailed description of your experiment design. This should include clear
indication of your instrument (e.g., questionnaire) and all other information relevant
to reproduce your experiment. You must justify all decisions in your design. (6
marks)
4. Give a step-by-step description of your experiment procedure. (6 marks)
5. Reflect on your experiment design and the experience of completing this
coursework. You should address what you learned and what you may do differently
next time. Make sure it is clear to the reader what you learned from the process of
designing and conducting human centred experiments. (4 marks)
You should use the criteria for assessment (see Table 5) as a set of guidelines for your
writing.
Submission Instructions
• Individual Report: You must submit an individual report via Learning Central by the
submission date and time (max 400 words). You MUST use the template (.md)

Q3
You are asked to conduct a statistical analysis of a dataset resulted from a user study. You
are asked to present your study and findings in the form of a report.
Assessment
type
Max. mark Max. length Format
Report 20 2 Pages .pdf
Your report will be assessed according to how well you are able to
• describe the dataset and research objectives, (4 marks)
• analyse the data and interpret the results of data analysis, and (8 marks)
• visualise the results of data analysis. (8 marks)
You should carry out a statistical analysis of the dataset to determine what the data tells
you about the user study and should visualise your results of data analysis in a way that
allows a reader to understand the findings of your study. You are free to use any software
package to conduct you study and generate visualisations.
1. The dataset
A user study was conducted to investigate the difference in display quality between two
different smartphones (i.e., referred to as S1 and S2). Also, the impact of gender on the
comparison between these two smartphones should be investigated. A number of
participants were recruited to assess the smartphones. Display quality was measured with
questionnaires, using the following method: each participant was asked to rate some
images displayed on S1 and some images displayed on S2, using a scale ranged from 0 (poor
quality) to 100 (excellent quality). The dataset is available on Learning Central as a Microsoft
Excel file. You should base your study entirely on the dataset provided.
2. The report
The report is limited to a maximum of TWO A4 pages including figures and tables. Arial font
size 11, with justification, should be used with Single line spacing throughout.
IMPORTANT! Any deviation from the instructions above will result in a deduction of 10% of
the maximum mark obtainable for the assessment. If you submit more than two pages as
instructed above, then ONLY THE FIRST TWO PAGES of the submission will be marked.
Extra submissions will be ignored.
IMPORTANT! Submission is via Learning Central. Submit your report as a single .pdf file –
NO other attachments or files should be included.
You should write a clear and concise report. Your writing should be brief and to the point. A
suggested structure for your report is shown below.
• Introduction: should provide a brief description of the dataset. You should clearly
state the research objectives.
• Data analysis: should consist of one or more sub-sections on a statistical analysis of
the data. You should formulate your research questions, describe the methods and
procedure of statistical tests and discuss the results of these tests. The titles of
these sub-sections should reflect what the sections contain.
• Data visualisation: should consist of ONE or TWO visualisations on the results of the
statistical data analysis. You should include accurate and informative axis labels and
titles. The captions should provide sufficient information to the readers without
referring to the related text in the report.
• [References are not required for the report.]
