Prototyping a method for the assessment of real-time EEG sonifications
(Georgia Institute of Technology, 2015-07)
This paper presents a first step in the development of a
methodology to compare the ability of different sonifications to
convey the fine temporal detail of the Electroencephalography
(EEG) brainwave signal in real time. ...
Onset asynchrony in spoken menus
(Georgia Institute of Technology, 2015-07)
The menu is an important interface component, which appears
unlikely to be completely superseded by modern search-based approaches.
For someone who is unable to attend a screen visually,
however, alternative non-visual ...
Haptic-auditory perceptual feedback based training for improving the spatial acoustic resolution of the visually impaired people
(Georgia Institute of Technology, 2015-07)
3D binaural sounds play an important role in the development
of navigational systems for the blind people. The use of
generic HRTFs in virtual auditory displays significantly
affects the acoustic spatial resolution and ...
Evaluation of reaction times to sound stimuli on mobile devices
(Georgia Institute of Technology, 2015-07)
When developing new devices for assistive technology, it is
important to consider auditory response times to different kinds
of warning and navigational sounds. Perception, processing and
action following the presentation ...
Designing auditory display of heart rate variability in biofeedback context
(Georgia Institute of Technology, 2015-07)
This paper presents a set of real-time sonifications of heart
rate variability in the context of biofeedback. The objective
of the study is to explore new ways in providing biofeedback
information rather than the typical ...
Guiding auditory attention toward the subtle components in electrocardiography sonification
(Georgia Institute of Technology, 2015-07)
ECG (electrocardiography) consists of a few components and
features that indicate the details of electrical conduction in each part of the heart. The simple pitch-mapping sonification of ECG cannot indicate these components ...
Can auditory display help us categorize seismic signals?
(Georgia Institute of Technology, 2015-07)
Recordings of the Earth’s surface oscillation (seismograms) can be
sonified such that most of the signal’s frequency spectrum falls in
the audible range. Then, the pattern-recognition capabilities of the
human auditory ...
Auditory assistance for timing presentations
(Georgia Institute of Technology, 2015-07)
Every presentation has to end at some point. Signaling
the approaching end of the presentation time in conferences is
often accomplished by showing signs with the remaining time
written on it, i.e., by visual contact. ...
Chemical spectral analysis through sonification
(Georgia Institute of Technology, 2015-07)
Chemical spectra are an important part of how research
chemists analyse the outcomes of experiments. However these
complex spectra can be very difficult and time consuming to analyse.
This paper outlines an investigation ...
Auditory Recognition of Floor Surfaces by Temporal and Spectral Cues of Walking
(2011-06)
In a multiple choice auditory experimental task, listeners had to
discriminate walks over floors made of concrete, wood, gravel,
or dried twigs. Sound stimuli were obtained by mixing temporal
and spectral signal components, ...
