Transducer Sound Dome Interaction

The Sound Port: Development of Abi-directional Sound Transducer

The realisation of a functional Sound Port would be aided considerably if a bi-directional transducer were available. Electrodynamic transducers are capable of being used as the basis of a such a transducer. An analogue circuit model has been established which can be used to simulate both directions of their operation with reasonable accuracy. An 'in progress' design for a method of recovering ...

Visualization of Transducer-Produced Sound Fields in Solids

Broadband ultrasonic pulses and monochromatic ultrasonic waves are visualized in various transparent solids using a photoelastic visualization technique. Application is made to the characterization of the sound field radiated by various ultrasonic transducers operating under various excitation and coupling

Realtime Dome Imaging and Interaction: Towards Immersive Design Environments

As engineering design becomes more and more complex, we predict that the field will look to immersive environments as a way to create more natural interactions with design ideas. But, helmets are bulky and awkward. A better solution for immersive design is a partial dome. Originally the exclusive domain of flight simulators, dome projection is now being brought to the masses with less expensive...

Sound Design for Affective Interaction

Different design approaches contributed to what we see today as the prevalent design paradigm for Human Computer Interaction; though they have been mostly applied to the visual aspect of interaction. In this paper we presented a proposal for sound design strategies that can be used in applications involving affective interaction. For testing our approach we propose the sonification of the Affec...
