back to top  1. cringeMACHINE

cringeMachine was an early prototype for an interactive public installation. The purpose of the project was to develop a sculptural, crystalline-like aggregate form that could be used to experiment with modular interactive systems and study their effect on public space. We also wanted to explore people’s reactions to its rudimentary agency. The sculpture incorporated a speaker, a sound sensor, and a simple Arduino circuit connected to linear array of LED lights, which reacted to sound levels around it in real time. This installation is evocative of systems in nature that develop from simple rules and behaviors to create an effect that is greater than the sum of its parts.

Loaded Dice is a co-design tool used to explore the design space of smart connected things. The tool consists of two Arduino-based 3D-printed cubes. One of the devices is equipped with a different sensor on each of its six sides, while the other is equipped with a different actuator on each side. Whichever side is on top is active, communicating wirelessly over distance with the top side of the other cube. Loaded Dice supports creativity, imagination, and exploration in the design process of smart and multisensory devices and services, especially in the early ideation stages.

Swarm user interfaces are a new class of human-computer interface comprising many autonomous robots that handle both display and interaction. Zooids is an open-source, open-hardware platform for developing tabletop swarm interfaces. The platform consists of a collection of custom-designed wheeled micro robots, each 2.6 cm in diameter, a radio base station, a high-speed digital-light processing (DLP) structured light projector for optical tracking, and a software framework for application development and control. We have explored the potential of tabletop swarm user interfaces through a set of application scenarios developed with Zooids and proposed general design considerations unique to swarm user interfaces.

Three Studies of Synaesthesia is a research project that attempts to explore some of the intriguing properties of synaesthesia. Three props highlight some provocative elements of synaesthesia that can be used within a design context. Prop 1 tries to illuminate the transformative properties of synaesthesia. Prop 2 explores real and surreal images of taste. Prop 3 mimics a narrative of anger-related synaesthesia. The peculiar properties of synaesthesia provide a speculative domain where people can explore potential interactive features within the context of design.

ins05.gif Prop 1 considers how weight and scale could be associated with each other. The liquid between the two glass sheets immediately expands its surface according to the pressure it receives on the glass surface.
ins06.gif Prop 2 is an attempt to question the difference between our mental images and the real images of taste. How does electricity taste in your mind? What does it really taste like?
ins07.gif Prop 3 mimics the narratives of anger-related synaesthesia and its level of intensity. When a user exerts force (anger) on the pad, the prop will make a noise and turn on the red LEDs proportionately to the amount of pressure received, indicating the amount of anger.
