Entrepreneurs and start-up founders using innovation spaces and hubs often find themselves inside a filter bubble or echo chamber, where like-minded people tend to come up with similar ideas and recommend similar approaches to innovation. This trend towards homophily and a polarisation of like-mindedness is aggravated by algorithmic filtering and recommender systems embedded in mobile technology and social media platforms. Yet, genuine innovation thrives on social inclusion fostering a diversity of ideas. To escape these echo chambers, we designed and tested the Skunkworks Finder - an exploratory tool that employs social network analysis to help users discover spaces of difference and otherness in their local urban innovation ecosystem.

With the increasing trend of students going abroad to pursue their higher education, cross-cultural collaboration has become increasingly important. This study explores what considerations need to be taken into account when designing a pedagogical tool that helps enhance cross-cultural communication in a co-located context. We use a multi-stage approach that starts with a survey and observations to understand what are the key contextual aspects of cross-cultural groups. In the second stage, we design a technology probe Contributor, an interactive tabletop interface, which is deployed in a workshop involving university students with practical experience in Human Computer Interaction (HCI). Results show that key considerations when designing for co-located cross-cultural collaboration tools in the context of higher education are: social accountability and visibility of prompts and accessibility of devices; focus on maintaining participants' attention to enhance conversation dynamics; focus on data privacy when monitoring actions of participants; and providing a platform for participants that allows externalization of ideas through annotations and visualizations, as well as highlighting keywords relevant to the discussion.

Many systems have been developed to support remote collaboration, where hand gestures or sketches can be shared. However, the effect of combining gesture and sketching together has not been fully explored and understood. In this paper we describe HandsInTouch, a system in which both hand gestures and sketches made by a remote helper are shown to a local user in real time. We conducted a user study to test the usability of the system and the usefulness of combing gesture and sketching for remote collaboration. We discuss results and make recommendations for system design and future work.1

It is challenging for dance teachers to provide feedback to all students learning to dance. This is a common problem in large social dance classes, where the teacher do not have time to reflect before giving feedback. One possible way to address this is to allow dance instructors, peers, or students themselves to assess students' performance using video recordings. In this paper, we explore the use of a video annotation tool by dance teachers. We focused on a particular style of partner dance: Forró. We followed a three-step process to design and validate the video annotation tool, which includes: 1) interviewing dance teachers to understand the context and their needs; 2) asking teachers to assess video recordings of students dancing to capture their 'vocabulary'; and 3) developing the video annotation tool. We conducted semi-structured interviews with four dance teachers to understand how the tool can support dance teaching. The contribution of this paper is the exploration of the use of video annotation as a tool to support dance teaching. The paper discusses a series of insights gained by teachers as a result of using our annotation tool which was carefully crafted based on dance education foundations and the vocabulary elicited from experienced dance teachers.

Greetings from the dry, dry world of Western Australia. Australia was largely cushioned from the worst of the effects of the Global Financial Crisis (GFC) because of the strength of its mining industry, strong regulatory banking controls and from the Government having budgeted for surpluses over several years. Western Australia was and still is the leading State in the country driving the national economy. However this year it has been our turn to experience a severe drought from the Gascoyne Region and through the whole south west of the State. Whilst Perth has only received about half of its annual average rainfall this year many parts the Wheatbelt have only received 10% or 20% and that means the total wheat, barley, oats and canola crops will only be less than half of the average production.

Hackathons have attracted increasing interest in recent years, and whereas much of the research focus on the role of hackathons as potential means for education, innovation, or municipal engagement, this paper focuses on the creative process of a hackathon. We present an explorative, autobiographical case study of a team at a hackathon and in the analysis we identify four factors, which in particular impacted the team's design judgement during the hackathon: 1) The hackathon format, 2) the available tools and materials, 3) the participants' domain knowledge, and 4) the participants' technical knowledge. Though the factors are evident in most design processes, we discuss how the four factors in a hackathon setting influenced the design judgement in a particular way and how the factors influenced the creative engagement in developing technology in the hackathon. We discuss potential implications for future research on how to understand design judgements made under the particular circumstances of a hackathon.

In contemporary design research and practice, food is often seen as a problem to be fixed. Designers in the corporate startup realm as well as in academic HFI (Human-Food Interaction) have proposed various techno-solutions to curb complex food system issues such as malnutrition and environmental unsustainability. Quantified diet trackers, 'smart' kitchenware, food sharing apps and similar digital food technologies present opportunities for efficient food practices but also challenges to human-food relationship and social food traditions. The Parlour of Futures project reflects on these contradictions and addresses the growing trend of food-technology innovation through the lens of Speculative and Critical Design (SCD). The project takes the form of a traditional Tarot parlour where participants explore possible food-tech futures as prophecies. Through a bespoke Food Tarot cards deck presenting speculative food practices such as Monsanta[n]ism, Gut Gardening, or Turing Foodism, the project provokes playful food-tech imaginaries and future food scenarios. We discuss the opportunities of SCD in nurturing reflective food design and research, and invite OzCHI attendees to contribute their future food ideas during the Parlour demo session.

People with intellectual disability are keen users of information technology, but the need for spelling and typing skills often presents a barrier to information and media search and access. The paper presents a study to understand how people with intellectual disabilities can use Voice Activated Interfaces (VAIs) to access information and assist in daily activities. The study involves observations and video analysis of 18 adults with intellectual disability using VAIs and performing 4 tasks: calibrating the VAIs, using voice assistant (Siri or Google) to search images, using voice to query Youtube, and using the voice assistant to perform a daily task (managing calendar, finding directions, etc.). 72% of participants stated that this was their preferred form of input. 50% could perform all four tasks they attempted with successful outcomes, and 55% three of the tasks. We identify the main barriers and opportunities for existing VAIs and suggest future improvements mainly around audio feedback given to participants. Notably, we found that participants' mental model of the VAIs was that of a person, implications for which include the user having to speak in long polite sentences and expecting voice responses and feedback about the state of the device. We suggest ways that VAIs can be adjusted so that they are more inclusive.

We herein demonstrate Tesla Blocks, a magnetism-based tangible 3D modeling system using block-shaped objects. The system recognizes the structure assembled by the user and draws the 3D model in real time. Each block of the system has a simple structure; we embed only a permanent magnet in a block. Because the electronic circuit used for recognizing the structure exists outside the blocks, the system is simple. Furthermore, occlusion by the user's hand does not occur in recognizing the structure.

Maps have been used in different ways to facilitate travellers in wayfinding. Depending on the traveller's ability to translate the direction on the map to the real world, maps are normally read at different orientations. Some have the ability to rotate the map mentally without having to change its original orientation and some require the map to be aligned with the direction of the intended path. Blind people are not excluded from using maps. A multimodal map that combines touch and hearing has been introduced to enable blind people to learn maps. However, such maps usually enable blind people to explore maps only in a fixed orientation. This raises a question of whether they might also benefit from the ability to change the orientation. Therefore, this paper investigates 12 blind people's preferences from a study conducted in Malaysia. The participants were required to explore five maps at different orientations in static and rotatable conditions based on the directional task given before performing a pointing task. Their preferences for the conditions were acquired through a series of interviews. Results showed that the blind participants did have their own preference when exploring the maps based on various reasons.
