Keynotes Speaker

Prof. Stephen Brewster

*Ultrasound haptics and levitation: the future of human-computer interaction?* Ultrasound provides some brand-new opportunities for interaction in user interfaces. In this talk, I will describe this new modality and what it offers to HCI. By using standard loudspeakers, we can create soundfields that generate haptic feedback in mid-air, without the user having to hold or touch anything. We can control the position and texture of this feedback in real time. This ‘mid-air’ haptics enables new interaction techniques around devices. I will give examples of how it can be used for virtual controls and how novel interactions can be designed. Another exciting possibility is the use of ultrasound to levitate small particles to create ‘physical’ pixels in the air in front of the user. These physical pixels can be precisely controlled to levitate 3D shapes and objects, which can be controlled dynamically. This opens up many new opportunities for displaying 3D models and data. In the talk, I will describe how to make this highly novel form of display possible and some of the interesting problems that arise around selecting and manipulating the levitated objects.

*HCI and UX Perspectives in Digital Transformation* Digital Transformation is a digital-first approach that takes a customer orientation to all aspects of a business, from its business model to customer experience to processes and operations. Successful digital transformation will increase productivity, value creation, and social welfare. Indonesia’s Digital Roadmap 2021-2024 is the guideline for digital transformation implementation in the country. The four main focuses of Indonesian digital transformation include digital infrastructure, digital governance, digital economy, and digital Society. In implementing digital transformation, we face many challenges, including the readiness of human resources to adopt digital technology and culture. There are often discrepancies between the plan and actual implementation. In this keynote talk, the speaker will share her experience and insights on how she has applied a Human-centred Design approach to navigate around many digital transformation projects in Indonesia as well as Australia, especially in education, financial, e-commerce, media, and entertainment as well as transportation industries in Indonesia as well as in Australia.

Fun with Creative Technology and Design


Everyone can be creative because everyone has the ability to make things. Human beings are wonderfully intricate pieces of machinery. In the effort to understand human intelligence and creativity (cognition), or how people design everything (from their meals to furniture, house, or software programs), we build models and machines (physical, digital, and interactive) to attempt to explain and simulate, or to explore the boundaries of these ideas that are inside black boxes.  In this talk, Ellen will introduce projects from ACME Lab at the ATLAS Institute, an interdisciplinary institute for radical creativity and invention.
