Callum Parker

Lecturer in Interaction Design

Hi, I’m Callum! I am a Lecturer in Interaction Design at the Urban Interfaces Lab in the University of Sydney’s School of Architecture, Design and Planning. My research seeks to gain new understanding of interactive digital city interfaces and their place within urban environments, contributing towards the broader smart city. I’m specifically focused on leveraging cutting edge technologies such as pervasive displays, {augmented, virtual, and mixed} realities, and media architecture.

Outside of research I coordinate and teach units across the undergraduate Design Computing and postgraduate Master of Electronic Arts and Interaction Design (MIDEA) degrees, including Designing for Virtual Reality, XR Design, and Interactive Product Design Studio (a capstone project for 3rd year design students).

Projects

Big Data Bugs

Smartphone-augmented reality (AR) application (app) for a local museum exhibit to display visualisations of geo-located data for entomology specimens. Visitors to the museum can spatially visualise insect specimens in-situ and view more detailed information through their own devices.

Snowballz

Virtual reality games, even though they were not explicitly designed for exercise, have the potential to provide enough exercise to achieve recommended levels of activity for a day while keeping people motivated. However, there is a risk of overexertion. Therefore, we designed and developed a virtual reality exergame called Snowballz, which utilises a user model and dynamic difficulty adjustment to deliver an ever changing level intensity according to the player’s energy and performance.

Pop-spot

We designed and developed an engagement popup to encourage people to stop and vote, provide feedback, and express their opinions about transport infrastructure on and around our University through a collection of interactive modules, including a touchscreen transit information screen, a selfie voting app (vote with the transport option you took to university), a chalkboard, and a chalk drawing robot (tallying the votes from live tweets to our popup's Twitter hashtag).

AR Tree Trimming Awareness Game

This game was a component for a community engagement popup for Ausgrid (a local power company) to raise awareness about tree trimming. I created a video see-through augmented reality (AR) headset mounted on a tripod, which people could look through to see AR content. The white boxes as shown in the photo are AR markers, one for the 3D tree and the other for the 3D powerlines. If they are too close together then the tree catches fire.

AR Assisted Personalisation

Users could engage with the content directly on-screen or through a custom developed smartphone augmented reality (AR) app. The app had two distinct features, overlay and remote control. The overlay allowed users to see personalised content overlaid on the display, based on a user profile containing user preferences stored in the app. The remote control feature enabled users to control the display by performing swipe gestures on the display through their smartphone's camera feed.

Tweet Wall

We designed and implemented a public display application that allows people to navigate between Twitter feeds and to find details about particular tweets. The application supports selection and navigation through point-and-dwell and push and grab-and-pull. A within-subject evaluation with 10 participants found that although point-and-dwell was perceived to be more accurate, push was preferred for selecting items and grab-and-pull was preferred for navigation.

Molypoly

MolyPoly is a 3D molecule construction simulation to help students grasp the concepts of chemistry easily through immersion and natural interaction with 3D molecules. It was designed to augment the teaching of organic chemistry with enhanced natural interaction and 3D visualisation techniques. The results from a user study with first year chemistry students demonstrated that students can achieve similar learning outcomes to those who study chemistry traditionally at the end of the four class sessions.
