Marsui

MARSUI (Malleable Audio-Reactive Shape-retaining User Interface) is a deformable hardware prototype exhibiting shape-retaining behavior. It can track the shape the user creates when deforming it. We envision that a set of predefined shapes could be mapped onto particular applications or functions. In its current implementation, we present three shapes that MARSUI can be formed into: a twist, a fold, and a bend. Since the malleable interface can also take other forms, feedback plays an important role in guiding the user toward the predefined shapes. In this project, we focus on investigating the possibilities that auditory feedback could offer in guiding the user toward reaching the intended shapes.

Mind Pool

Mind Pool is a brain-computer interface designed to provoke self-reflection experiences based upon real-time representations of a participant’s brain activity. Brain activity is sonically and physically represented via a magnetically reactive liquid sitting in a pool built into a tabletop. Feedback may be intentionally altered by those sitting at the Mind Pool by entering into differing mental, sensory, and bodily states or passively through observation of inherent brain activity.

The aim of the system is to present this information ambiguously to encourage sustained interactions and self-reflection by engaging participants in relating the ambiguous feedback with their brain activity.

Enhancing Saltiness with Cathodal Current

Weak cathodal current applied to the tongue inhibits the taste of salt, but perceived saltiness tends to increase after the current is released. In this study, we propose a saltiness enhancer that uses this phenomenon. Our system applies weak cathodal current for a short time when the user eats or drinks. The user can thus perceive a salty taste without the use of salt.

Cell

Cell is a pneumatically controlled wearable/sculpture/installation. In installation form, the piece is suspended in space as a flayed skin, coming to life as users breath into its overhanging tentacles. As groups of balloons swell and shrink the piece transforms, extruding shapes in various directions.

In performance, the piece augments and distorts the performer’s body as it metamorphoses, fusing its own body with that of the performer to create uncanny anthropomorphic hybrid forms. As the balloons swell they push outwardly, at the same time applying pressure on the body itself, realizing for the performer the skin’s boundary with the environment.
