Mini Challenge 2 Results!

Hello Challengers!

We have been reviewing the fantastic submissions for mini challenge 2, and finally could decide a verdict. The main criteria were your creativity and how you meaningfully executed a solution to your problem definition.

So many teams did excellent work, we needed to scrutinize our own scores to decide on a winner – The Bridge!! Congratulations! Your solution was meaningful and addressed your problem definition precisely.

The closest teams were the Misfits and Why See Design, both teams had a very clear problem definition and had solutions which worked well towards solving them! – An honorable mention goes out to you all.

Congratulations to everyone and good luck with the rest of the challenge.

Meet the Committee


lobster2Jen is the Chair of the OzCHI Student Design Challenge 2017 and has been busy reading your posts, responding to your emails, and coordinating all things OzCHI24. She is a PhD Student at the Queensland University of Technology in the area of participatory, cross-cultural design. Jen’s team ‘The Normans’ from the Australian National University, Canberra, Australia, won OzCHI24 in 2015.

Jen’s favourite part of OzCHI24: “OzCHI24 was a fantastic learning opportunity, and I enjoyed gaining experience in a wide range of different design activities within the 24 hour period. Attending the OzCHI conference as a finalist and networking with the OzCHI community was important for my career development as I met my PhD supervisor and colleagues there.”

What Jen learnt from OzCHI24: “Design is not linear. While the phases of the Double Diamond could be interpreted as ‘steps’ in the design process, design is much messier in practice. We backtracked, skipped forward, revisited previous steps, and engaged in different phases concurrently as need and time constraints demanded.”

Tips for this year’s teams:

Make sure you take some breaks, stay hydrated, and eat something green between all the caffeine and sugar hits 😉


Diego is a member of the Committee of the OzCHI Student Design Challenge 2017 and is managing the submission system and the OzCHI24 website this year. He is a PhD Student at the Queensland University of Technology in Human Computer Interaction, studying the changes in the dynamics of the relationship between parents and children after children leave home. Diego was a contestant on 2016, as a member of ‘The Global Gang’ team.

Diego considers that “OzCHI24 Challenge is an excellent opportunity to experience the complete design and writing process in an extremely short period of time. The 24 hour period can bring the best of yourself in many facets: from analysing how to solve a problem to how to work as a team.”

What Diego learnt from OzCHI24: “Even if you do not get into the finalists, there are plenty of positive things you can get from the challenge. For me, it is very important to have a good communication with your team, and to listen to everyone’s thoughts and ideas.”

Tips for this year’s teams:

Eat well, take time to rest, and enjoy the experience!


Shannon is a committee member for this year’s OzCHI24 challenge, and is also an undergraduate student from the Queensland University of Technology, studying a bachelor of Information Technology and majoring in Computer Science. Her interest in HCI began in 2015 when she decided to take a minor in HCI, learning various research and design methods. Subsequently, Shannon developed an interest in sleep technologies, and now works as a Research Assistant at QUT in her spare time, focusing on adolescents and their sleep patterns and lifestyle.

Shannon’s team ‘Doppio’ was shortlisted in the 2016 OzCHI24 challenge, she felt that the challenge was beneficial to her development in HCI. Her favourite thing about the challenge was working with a group of passionate people, with the ability to share knowledge with each other and develop new skills whilst applying her current skills to produce a meaningful solution. She was also intrigued to see how much work her team was capable of within 24 hours, and was pleasantly surprised.

Shannon’s advice for the challenge:

Be imaginative, and don’t forget to take care of yourself during the 24 hours! Sleeping is completely fine, we advise it.

Mini Challenge 2: Magic Machines

Welcome to the second Mini Challenge for the OzCHI Student Design Challenge 2017.

The aim of this mini challenge is to help you find different ways and ideas to solve the problem that your team has identified during the first hours of this competition. In this mini challenge, you will utilise an adaptation of the “magic machine” method described in this paper.

The “magic machine” method is a design fiction method that can be used for fostering the creation of new design concepts to solve a problem, by creating absurd solutions from lo-fi materials. Magic machines are imaginary devices that can do anything that you imagine, even if it is not realistic or feasible as a real technology.

For this mini challenge, your team will create a magic machine to solve a problem relating to the challenge topic of design for sharing. Drawing on your team’s brainstorming and discussion, you should choose a problem or issue and use this as a starting point for the creation of the magic machine.

Mini challenge 2 is due to 5PM AEST.

Here is a description of the steps to follow for this mini challenge, the expected outcome, and an example of what you should post to your blog:


Step 1: Define your problem together in one sentence or two.

Step 2: Create a lo-fi prototype of “magic machine” that can solve this problem (and tell us how). It can be a simple drawing, or an imaginary device made of cardboard, or made up of existing objects.

Step 3: Create a blog post that presents your magic machine and summarises the features you like and dislike about it. Make a list of the things that make this magic machine solve your problem, and of what you think that can contribute to finding a feasible solution for your project.

Expected outcome:

You must publish the following on your blog:

  1. Photos and brief descriptions (a couple of sentences) of your magic machine
  2. A table with the things you like and dislike about your magic machine, and a list of things that you learnt from the magic machine that can contribute to your solution.


Things we like Things we dislike Things that could contribute to our solution


In this example, we present an imaginary problem, a photos that show the magic machine and how it works, and a filled table as the presented above.

Problem: Sometimes a person needs to make important decisions that can affect his/her partner, and it is not possible to get the other person’s opinion on that moment.

Magic machine:

This glasses-gloves set can make you take control of your partner’s movements. The glasses allow you to see in real time everything that your partner is seeing. The glove allows you to take full control of the partner’s right hand movement.

Example Magic Machine

Photos taken with an iPhone, collage made with the Photo Collage Editor app on Android.


Things we like

– Real-time connection

– Real-time influence

Things we dislike

– Privacy issues

– Too much power for who controls movement

Things that could contribute to our solution:

– Real-time awareness of opinion

– It would be good to find a way to subtly communicate opinions in real time


OzCHI24 Paper Writing Guide 2017

This year we’re once again using an academic format. This has many benefits such as:

  • Gives you experience writing in academic style that will be assessed in a peer-review structure
  • Standardising referencing, which makes it easier for your reviewers to follow your justifications for your solution, and thus understand your submission
  • Standardising the format, which helps us compare and review all the submissions
  • Allows you to include images, tables, and images in your paper to help strengthen your arguments
  • Simplifies turning the top team entries into a publication format

As per the challenge brief, you will be using the 2017 SIGCHI Extended Abstract format. Since this is a brand new template, we do not have any examples on hand with the 2017 formatting. Here are some sample papers in the Extended Abstract style using the previous template.

Use references! References provide grounding to the real world and show that your solution isn’t just based on assumptions. For example, you could use the paper by Light et al. found on the challenge brief page to support discussion of design goals. Whenever you use someone else’s work, you should include a reference.

It is a good idea to start working on your paper early. Don’t leave it to the last hour! Start early, and fill in content as you go along using the structure below.

How to structure your paper

The structure of your paper might look something like this:


Make sure your title is not too generic, for example don’t make it simply “Designing for sharing with others”. If your solution is a specific application with a name, it’s a good idea to include the name in the title and then specify what it does.


Write a short abstract (up to 150 words) that summarises the design problem, your design process, your solution and the rationale for your design concept.

The Problem

Briefly introduce the challenge problem, including any additional background research you might have done and the specific situation of use that you are addressing.


Outline your method/approach to the challenge. Try to have at least one reference justifying the approach you took. Remember that you must not gather primary data as part of your methods.


Show us your solution, demonstrate or tell us why it will be effective, how people will use it, etc. You should focus on showing us what happened through both pictures and discussion.


Summarise the key points from the paper. You may suggest some possible future work that could build on your design concept.


List your references using the ACM SIGCHI Referencing style. Examples of this referencing style can be found on the Paper Template. Remember to include both your blog’s and your submitted video’s URLs as references.


It’s a good idea to look at examples of how other papers are written. In particular we recommend you to take a look at some of the OzCHI Student Design Challenge papers from previous years.

Additional Information

OzCHI Student Design Challenge submissions will undergo a single blind jurying/review process. Therefore, you should include full author information and contact details in your initial submission.

Don’t worry about filling in the CCS CONCEPTS and KEYWORDS sections. Keep the heading and sample text from the initial template, and we will help the finalist teams to choose CCS concepts, keywords, and suggested reference for their submissions.

Don’t worry about changing the document header, just keep this sample text from the template:

Magnetic Normal Modes of Bi-Component Permalloy Structures) WOODSTOCK’97, July 2016, El Paso, Texas USA


Mini Challenge 1 Results!

Hello Challengers!

It is time to announce the results of the first mini-challenge, brainstorming. The mini-challenge was judged on your creativity and originality of your outcome, how the meaning of sharing, interactions, position of technology, and outcomes for the people involved are presented in your visualization, and the overall visuals of your submission.

We have received a wide range of visualizations that show some very interesting examples of sharing.

We would like to give an honourable mention to teams CodeGreen, who did a very extensive brainstorming for each of the questions, and The Bridge, who found very interesting themes related to the concept of sharing. Unfortunately, there can be only one winner and that is Elemelons 2.0!

Elemelons 2.0 showed a clear and original example that showed all the different aspects of sharing that we were looking for, in a simple and creative way.

Congratulations to everyone and good luck with the rest of the challenge!

Meet Our Sponsors


We are excited to have the Human Factors and Ergonomics Society of Australia (HFESA) return as a sponsor for OzCHI24 this year! As their name implies, HFESA seeks to promote human factors and ergonomics, and for you as students this is perhaps best expressed through their involvement with various academic groups. In its capacity as the parent body for Australia’s Computer-Human Interaction Special Interest Group (CHISIG), HFESA facilitates the OzCHI conference and various activities of CHISIG.

As always HFESA looks forward to seeing the what you all will come up with during the 24 hours, and is eagerly awaiting the three finalist teams presentations at OzCHI in Brisbane!


We are also really happy to have Rosenfeld Media this year. Rosenfeld seeks to promote knowledge and expertise related to UX, by publishing books, teaching and consulting. They have sponsored us with five wonderful books as prizes for this competition!

Mini Challenge 1: Brainstorming

We have posted the team list up on the website! Please check your details at We have emailed some teams with missing or incorrect information.

You’ve known what the Challenge brief is for a few hours now, so it’s time to put your understanding to work with Mini Challenge 1: Brainstorming!

Step 1: Brainstorm about the following prompt (to get you thinking!):

Tell us about the last time you ‘shared’ something with someone

Think about:

  • What the word ‘sharing’ means in your example
  • What types of interactions were facilitated by sharing something
  • How technology was positioned (or not?) in the sharing
  • The outcomes for the people directly involved in the sharing, and for the broader community

Step 2: After your brainstorming process, please create a visualisation of your response to the prompt

The visualisation can take any form you choose, including a rich picture, a diagram, or a mind map.

Step 3: To submit your mini challenge entry, publish it on your team blog and post a comment here with the URL to your entry.

Mini Challenge 1 is due in one hour at 1PM AEST.

The mini challenges are optional but will support your progress in the competition (and we will send certificates to the winning mini challenge team!)

THE OzCHI24 2017 CHALLENGE BRIEF: Design for Sharing

1. THE OzCHI24 2017 CHALLENGE: Design for Sharing

The existence of the human race is contingent on sharing the planet with each other and with a rich array of plant and animal species in our natural environment. However, large scale imbalances in the sharing of resources are resulting in problems such as environmental destruction, war and displacement, and widening socio-economic inequalities between people (Light et al. 2017). Looking at these problems that are bigger than ourselves, we might feel overwhelmed or uncertain about what meaningful actions we can take in our own lives to affect a positive change for the “common good” (ibid.).

Technology design can have a role in making futures for ourselves that enrich our relationships with other humans and with nature, bringing to the fore our better human nature. Design scholars such as Ann Light suggest that a “sustainable society is one in which we choose positive behaviours that make us feel happier, more connected and more disposed to help others” (Light and Miskelly 2014). One place for designers to start is to consider what role technology can play in enabling people to share and give back in their community, enriching social connectedness and supporting environmental sustainability.

New digital platforms have facilitated sharing of a wide range of resources within local communities, with prominent examples including Freecycle, AirBnB, Uber, and Taskrabbit (with others in Malmborg et al. 2015). Sharing can take many forms, including “giving something up”, “exchanging for things other than cash”, “fixing something for the benefit of everyone”, or “pooling […] time and expertise, skills and resources” (Light and Miskelly 2014). Different conceptualisations of sharing and the sharing economy, including the “collaborative economy”, “shared economy”, and “collaborative consumption” have differing foci, with varying social and economic implications (Botsman 2015). A key distinction is whether a service is collective or individual and whether it is paid for or free (Light and Miskelly 2015).

Sharing can bring about new types of interactions and engagement between people within a community, and feed into our broader social and environmental systems.

Your challenge is to create a design concept that supports “sharing and giving back” in a community. You must address the following questions in your paper and video submission:

  • What is ‘designing for sharing’, and what type of sharing does your design intervention support or facilitate?
  • What particular community (physical or virtual) is your team designing for?
  • How could this design intervention enrich people’s interaction and engagement with their community and with the environment?
  • How does your design intervention engage with new and emerging technologies?
  • What types of interactions and experiences does your design intervention facilitate?
  • What are the strengths and weaknesses of your approach?

2. Where to start

Make a start on understanding the problem space by reviewing the following literature:

Once you have finished reviewing this literature, start working through your ideas about the problem space as a team. What does “sharing” mean? How is sharing enacted in local communities? What role does technology play in sharing? What opportunities might there be for design interventions related to sharing?

3. Important change in 2017: No primary data gathering

We have introduced an important change to OzCHI24 in 2017. This year, teams will not be permitted to gather primary data from people outside of your team such as seeking user insights and feedback from external participants through interviews, surveys, or any other primary data gathering method.

If needed, you can use data gathered from within your team (e.g. brainstorming, reflection, use of design methods such as workshop activities with only your team members), or use secondary sources. The following link provides a definition and examples of primary and secondary data:

You are not expected to gather primary data about your community or conduct an evaluation of your design concept using external participants. However, you need to demonstrate originality and a good use of design research methods in your:

  • Introduction: How clearly did you communication the problem space and the rationale for your design concept?
  • Literature review: How well did you use the secondary sources that are already available?
  • Ideation: What process did you follow to come up with your idea concepts? How interesting are your design ideas, and how well did they address the challenge brief?
  • Prototyping: How well was your design concept conveyed through your prototype/video?
  • Discussion and reflection: How well were you able to reflect on the interactions and experiences that your design concept could facilitate, and the strengths and weaknesses of your approach?

Some examples of primary and secondary data gathering methods as follows:

Primary data involving participants outside of your team (NOT ALLOWED) Secondary data and internal data (ALLOWED)
  • Interviews
  • Surveys
  • Focus groups
  • Cultural probes
  • Focus groups
  • Participant observation etc
  • Secondary sources (e.g. existing literature, prior work)
  • Publically available datasets
  • Self-reflection, brainstorming, and use of design methods within your team

4. Submission

4.1 What you will be submitting

1) Paper

To describe your design intervention, you are asked to write a brief ‘mini paper’ in academic style using the Microsoft Word 2017 SIGCHI Extended Abstract Template (no LaTeX).

To access the template:

  • Follow this link:
  • Download either the Windows or Mac version of the Master Template (.zip)
  • Navigate to the folder ‘ACM Sample Files’
  • Open the file called SigChi-a.docx (please ensure that you choose the file name with -a)
  • Replace the content in the same paper with your own content, ensuring that the formatting remains the same

In your paper you must explain the design concept, design process, and address the questions in the brief and evaluation criteria.

You are strongly encouraged to include research references such as journals and conference papers, and other relevant links in the paper. Feel free to include pictures and diagrams in the body of your paper!

Your submission should be up to six pages long including references. There is plenty of space in the column margin for images, diagrams, tables, and figures.

Finally, don’t panic! The Extended Abstract paper format is succinct, and we understand that it’s a 24-hour challenge, so this will be taken into consideration when we read your submissions.

In a few hours time, we will publish a ‘Paper Writing Guide’ post with further detail on how to structure and format your submission.

2) Video

To demonstrate your design concept and use scenarios, you must create a video prototype or a concept video that demonstrates an early stage prototype in use. Anything from animation through screen capture to acting is valid.

The video should be strictly no more than 3 minutes long. Be sure to include a title and your team name somewhere throughout the video.

Include a link to your video submission in your Paper’s references section and in the paper submission form.

3) Team blog (not assessed)

To showcase your research and design process you need to maintain a team blog (online journal) throughout the entire 24-hour challenge. This blog should include key parts of your process such as prototyping and the various methodologies you utilise. It’s not necessary for you to post any results of ideas before the end of the challenge; however, it’s beneficial for us to understand the methodologies you used and what your process was to verify your submission.

Use your team blog to provide us with ‘behind the scenes’ insights into your design process, and showcase every aspect of your design journey. Please use #ozchi24 for tagging any challenge-related posts.

4) Mini challenges (not assessed)

We will be running a series of three optional mini-challenges that are designed to give you some direction and help you develop your final submission. Mini challenges will be released gradually on the OzCHI24 website during the challenge period. Mini-challenge entries can be submitted by posting your work to your team’s blog, and commenting on the mini challenge instructions post with your blog post URL. Mini challenge winners will receive certificates.

4.2 Evaluation Criteria (What we’ll be looking for)

Your video and paper will be assessed together against the following criteria:

  1. Demonstrated understanding of the problem. Your submission should provide details of, and gives context to, a real world problem while providing insight into user experience and interaction.
  2. Method and approach. The quality of your design process, and use of interaction design methods and theory.
  3. Creativity, quality, innovation, and originality of design concept.
  4. Quality of submission, including visual style, clarity, and depth.

The paper evaluation process is as follows:

  • All papers will be assessed by a jury
  • The most highly ranked papers will be shortlisted for review by an international panel of reviewers for more detailed comments and scoring
  • The top 3 reviewed papers will be chosen as finalists to present at the OzCHI conference.

4.3 How to Submit
