This paper describes Squeezy: a low-cost, tangible input device that adds multi-dimensional input to capacitive multi-touch tablet devices. Force input is implemented through force sensing resistors mounted on a rubber ball, which also provides passive haptic feedback. A microcontroller samples and transmits the measured pressure information. Conductive(More)
We capture key factors of a group meal with communication and interface technologies to make a meal more enjoyable for diners who cannot be collocated. We determined three factors of a popular group meal, Chinese hotpot, that are essential for a group meal experience: interacting as a group with food, a central shared hotpot, and a feeling that others are(More)
We propose a novel geometric skinning approach that unifies geometric blending for rigid-body models with embedded surfaces for finite-element models. The resulting skinning method provides flexibility for modelers and animators to select the desired dynamic degrees-of-freedom through a combination of coupled rigid and deformable structures connected to a(More)
We present the integration of two musical interfaces into a new music-making system that seeks to capture the experience of a choir and bring it into the mobile space. This system relies on three pervasive technologies that each support a different part of the musical experience. First, the mobile device application for performing with an artificial voice,(More)
Embodied interaction has the potential to provide users with uniquely engaging and meaningful experiences. m+m: Movement + Meaning middleware is an open source software framework that enables users to construct real-time, interactive systems that are based on movement data. The acquisition, processing, and rendering of movement data can be local or(More)
Vocal production is one of the most ubiquitous and expressive activities of people, yet understanding its production and synthesis remains elusive. When vocal synthesis is elevated to include new forms of singing and sound production, fundamental changes to culture and musical expression emerge. Nowadays, Text-To-Speech (TTS) synthesis seems unable to(More)
<b>What Does A Body Know?</b> is a concert work for Digital Ventriloquized Actor (DiVA) and sound clips. A DiVA is a real time gesture-controlled formant-based speech synthesizer using a Cyberglove&#174;, touchglove, and Polhemus Tracker&#174; as the main interfaces. When used in conjunction with the performer's own voice solos and "duets" can be performed(More)
This paper describes the motivation and process of developing a musical instrument for an unborn child. Well established research shows a fetus in the womb can respond to and benefit from stimuli from the outside world. A musical instrument designed for this unique context can leverage the power of this interaction. Two prototypes were constructed and(More)
We have added a dynamic bio-mechanical mapping layer that contains a model of the human vocal tract with tongue muscle activations as input and tract geometry as output to a real time gesture controlled voice synthesizer system used for musical performance and speech research. Using this mapping layer, we conducted user studies comparing controlling the(More)
By building a wired passive stylus we have added pressure sensitivity to existing capacitive touch screen devices for less than $10 in materials, about 1/10th the cost of existing solutions. The stylus makes use of the built-in audio interface that is available on most smartphones and tablets on the market today. Limitations of the device include the(More)
