• Postgraduates and undergraduates will have different assignment contexts.

Assumed Knowledge

The assumed knowledge for this course is that you have basic knowledge of computer science and know how to write a report and/or essay for your assignments. Because students come from a variety of backgrounds, with different knowledge bases, the assumed knowledge is not extensive. The course does, however, involve extensive reading.

Student Learning Outcomes

Teaching Rationale

Failing to take into consideration the needs of your software user audience will lead to costly disaster. People will become frustrated because the application does not work the way that they expect. You know it yourself – you have encountered web sites that are difficult and non-intuitive to use. We aim to show you a design process that helps reduce such user interface difficulties before users are unleashed on your software. This design process starts with understanding people. The process involves an on-going working relationship with potential users during the entire design of a system; not just in the software-testing phase.

Engineers have created many software applications without consultation with the immediate user audience. They may have talked to the managers of the software (those that will pay the development cost bills) but have not talked to the end users. The end users have valuable insight into the workflow of organizations, and this is complimented with knowledge from other stakeholders.

The intention is not for lectures to reiterate the text material but to re-activate it, re-represent it, elaborate it, and demonstrate the application of it to design. This implies, and it will be assumed, that you have done the reading prior to lecture. If you have questions about the reading, the lectures, or the interrelation between the two, make sure that you ask in lectures or via the various consultation methods described below.

Teaching Strategies

You will be expected to have listened to the relevant lecture in advance of tutorials, completed any associated Design Diary activities, and to come prepared to the online class. Further exercises will take place in the tutorials.

Each week you will be required to participate in your timetabled tutorial/laboratory class. This will be held online using Blackboard Collaborate or if you have enrolled in a face-to-face tutorial it will be in the CHI lab (G13) on the ground floor of K17. You will be using Microsoft OneNote which is a part of Ms Teams for Design diary activities. There are five sections including tutorial exercises, lecture exercises, assignment 2 checkpoints, class notes, and design ideas in your OneNote. Please make sure that you create the pages related to each topic under that topic and remember to date each page . Your OneNote will act as evidence of your original design and assignment work which is a compulsory component of this course.

Regular progress on assignment 2 group work is required and will be checked with weekly deliverables. This is designed to keep you working regularly on your assignments so that you don’t leave things until the last minute. During some scheduled tutorial classes (see website and assignment pages for dates) there will be assessable in-class activities and checkpoints (due at the beginning of the class) relating to assignment milestones. Late penalties may be applied if you have not adequately prepared for these activities or made contact with your tutor and group members if you cannot attend in real-time.

This will also be a time for you to ask questions of your tutor, and for your tutor to give you some feedback on your work.

The practical periods in the tutorial/laboratory are intended to facilitate group discussion and to give you the ability to work through practical examples. The tutorials will be a combination of some face-to-face and other online classes, but participation and attendance are still expected, in both cohorts. If you are enrolled in a face-to-face tutorial, your classes with be in the CHI lab in G13 on the ground floor of K17. If you are enrolled in an online class and you are having internet connectivity issues, please ensure you document the details, submit a request for consideration with your tutor and ensure you still complete all the associated work and exercises and submit them to the tutor to check, in a timely manner. You are expected to attend 80% of your tutorials. If you miss a tutorial you are expected to submit documented evidence of the absence such as a Drs note, proof of a COVID test, or the like. In special circumstances, which include documented evidence that is health-related, hybrid attendance could on occasion be negotiated with your tutor.

Your OneNote design diary will be marked regularly for assessment and review. You are encouraged to find your own design examples of bad user interaction experiences, as you go about your daily routine. This may involve you taking a photograph, as an example, and uploading a copy of that photo into your diary, and writing up your ideas as to why the interaction is poor and solutions to improve.

Things to consider

• Unlike code, you cannot hack out a solution the night before
• Design takes a lot more thinking and conceptualisation to explore the problem space
• The process is iterative and you must demonstrate improvements that evolve from iteration
• Your design work involves discussing issues with potential users
• Your design work involves discussing and working with others in your group

Lecture recordings:

• We will be using a combination of recorded lectures and livestream. Details and recordings will be available in Moodle.

Student Conduct

The Student Code of Conduct ( Information , Policy ) sets out what the University expects from students as members of the UNSW community. As well as the learning, teaching and research environment, the University aims to provide an environment that enables students to achieve their full potential and to provide an experience consistent with the University's values and guiding principles. A condition of enrolment is that students inform themselves of the University's rules and policies affecting them, and conduct themselves accordingly.

In particular, students have the responsibility to observe standards of equity and respect in dealing with every member of the University community. This applies to all activities on UNSW premises and all external activities related to study and research. This includes behaviour in person as well as behaviour on social media, for example Facebook groups set up for the purpose of discussing UNSW courses or course work. Behaviour that is considered in breach of the Student Code Policy as discriminatory, sexually inappropriate, bullying, harassing, invading another’s privacy or causing any person to fear for their personal safety is serious misconduct and can lead to severe penalties, including suspension or exclusion from UNSW.

If you have any concerns, you may raise them with your lecturer, or approach the School Ethics Officer , Grievance Officer , or one of the student representatives.

Plagiarism is defined as using the words or ideas of others and presenting them as your own. UNSW and CSE treat plagiarism as academic misconduct, which means that it carries penalties as severe as being excluded from further study at UNSW. UNSW has an ongoing commitment to fostering a culture of learning informed by academic integrity. All UNSW staff and students have a responsibility to adhere to this principle of academic integrity. Plagiarism undermines academic integrity and is not tolerated at UNSW. There are several on-line sources to help you understand what plagiarism is and how it is dealt with at UNSW.

Make sure that you read and understand these. Ignorance is not accepted as an excuse for plagiarism. In particular, you are also responsible that your assignment files are not accessible by anyone but you by setting the correct permissions in your CSE directory and code repository, if using these and related resources. Note also that plagiarism includes paying or asking another person to do a piece of work for you and then submitting it as your own work.

If you haven't done so yet, please take the time to read the full text of

UNSW's policy regarding Academic Integrity and Plagiarism

Assessment

All students (COMP3511/COMP9511) will complete 2 assignments.

• Assignment 1 – Individual Website Design Critique
• Assignment 2 – Group User Interface Design

Assignment 1 focuses on heuristic evaluation, design principles, and usability principles. For Postgraduates and Undergraduates, you will apply your understanding of these concepts when evaluating a website.

Assignment 2 context will differ between postgraduates and undergraduates to cater for the different experiences and learning approaches. This strategy has been formulated based on our own observations and feedback from students.

Assignment 2 is a group design activity where the group will carry out a full user centred design process to create a series of paper and electronic prototypes of a system. The process starts with design conceptualisation, analysing user needs and goals, through several design iterations from low to high fidelity prototypes, with on-going evaluation. You will discover through your testing that your first design will have flaws and not work the way the user expects. Iteration becomes an essential technique to improve the situation. Iteration is combined with an evaluation process to formally analyse whether improvements are being made.

Assignment 2 is heavily focused on prototype design and introduces the formal evaluation process. Group members must be from the same tutorial class because assessable exercises are carried out in tutorial time – so all group members must be present online when assessment is taking place.

• Late penalties for assignment work will be applied to submissions received after the due date. 10% of the total assignment mark will be deducted from the assigned mark per day late. Assignment more than 5 days late will not be marked as they will automatically fail.
• Late penalties for tutorial deliverables will be applied if they are not received or completed by the beginning of class.
• All electronic work submitted will be retained by the University of New South Wales and can be used for teaching, research and review purposes. We will acknowledge your contribution if you wish, or will withhold your name should you choose to remain anonymous.
• All submissions can be checked for plagiarism.
• Peer review software will be used for group projects, to assess relative contribution of each group member to the assignment. Marks will be scaled according to individual level of contribution. Details will be released with the assignment. It is to be noted that group assignment marks will not be released until ALL group members have completed a peer review. The peer-review process requires student confidentiality to be effective, so please do NOT share the details or outcomes with your fellow group members. Failure to complete your peer review may result in penalties to your final assignment mark.
• Please ensure you turn up (online) to the final exam and do not get the date or time incorrect.

Course Evaluation and Development

We will use both lab-based feedback and/or electronic survey tools to gather feedback about the course. This is used to assess the quality of the course in order to make on going improvements. We do take this feedback seriously and approach the design of this course using user centred design philosophies. Students are also encouraged to provide informal feedback during the session, and to let the lecturer in charge know of any problems, as soon as they arise. Suggestions will be listened to very openly, positively, constructively and thankfully, and every reasonable effort will be made to address them.

Students valued the up to date lecture content and slides, which we will strive to maintain. Lecture recordings will be available online, with the onus on students to ensure they listen to each lecture BEFORE their tutorials so they can keep pace with the course and tutorial requirements.

Student feedback indicated that guest lectures as well as the perspectives of different lecturers were valuable, and so we will continue to provide these.

A few students asked for shorter more concise lectures. However, other students really enjoyed the detailed examples which they indicated supported their learning and understanding. And yet other students asked for more examples. We thus aim to provide a balance between these competing demands in large student cohorts. A few students requested more concise assignment milestones. We provide reminders in many formats including the assignment specifications, lecture summary notes, and in tutorials. We will, however, endeavor to keep things more concise. The onus is still on individual students to track these on a weekly basis, otherwise it is easy to fall behind and miss deadlines. We note that HCI is an ill-defined domain, so assignment specifications will never be as clear-cut or concise as most other CSE subjects, and so we provide this extra support, which students value.

Based on the students’ survey results in 2021 regarding the workload, feedback, practical components of the course, and lecture contents, we made the modifications below:

• The workload of the course is decreased by cutting one of the major components of Assignment two. This assignment is now designed to be a group work without any individual components.
• As a result of student request for more individual feedback, you will be receiving feedback for the design diaries in addition to the assignments. The purpose of this, is to improve your learning experience and help you apply what you have learned from your earlier misunderstandings, to later aspect of the course.
• Assignments are updated so that you can obtain practical experience from the lecture content and you can then implement some of the concepts in practice in the assignments.
• Although, we update the lecture content every term, this term, the lecture content for the lectures related to new technologies is further updated to reflect new emerging devices and technologies.

Other Matters

Students are expected to attend all classes.

Students are expected to read their UNSW emails regularly. They are also expected to use their UNSW email addresses for all UNSW related communications.
