Tangible progress: less is more in Somewire audio spaces

We developed four widely different interfaces for users ofSomewire, a prototype audio-only media space. We informally studiedusers experiences with the two screen- based interfaces. Weprototyped a non-screen-based interface as an example of a noveltangible interface for a communication system. We explored theconflict between privacy and simplicity of representation, andidentified two unresolved topics: the role of audio quality and theprospects for scsiling audio spaces beyond a single Workgroup.Finally, we formulated a set of design guidelines for control andrepresentation in audio spaces, as follows: GUIs are notwell-suited to audio spaces, users do not require control overlocalization or other audio attributes, and awareness of otherusers presence is desirable.

Wearable apparatus for measuring displacement of an in vivo tympanum and methods and systems for use therewith

Methods and systems for sensing an auditory environment using a tympanic membrane of an individual are disclosed. An embodiment of a method comprises a step of dynamically sensing a displacement of the tympanic membrane in response to excitation by the auditory environment. An electrical signal based upon the sensed displacement is produced. Consequently, the electrical signal is representative of the auditory environment as sensed by the individual. Embodiments for sensing the displacement of the tympanic membrane are based upon laser interferometry and ultrasonic ranging. Further disclosed are methods and systems for modifying a sensed auditory environment, and methods and systems for producing a virtual auditory environment based upon directly sensing the displacement of the tympanic membrane of an individual.
