Active stereo sound localization
- The Journal of the Acoustical Society of America
, 2003
"... Estimating the direction of arrival of sound in three dimensional space is typically performed by generalized time-delay processing on a set of signals from a fixed array of omnidirectional microphones. This requires specialized multichannel A/D hardware, and careful arrangement of the microphones i ..."

Auditory Immersion with Stereo Sound in a Mobile Robotic Telepresence System
"... Abstract Auditory immersion plays a significant role in generating a good feeling of presence for users driving a telepresence robot. In this paper, one of the key characteristics of auditory immersion -sound source localization (SSL) -is studied from the perspective of those who operate telepresen ..."

A Simple Adaptive Matrixing Scheme for Efficient Coding of Stereo Sound
- Proc. EUSIPCO'05, Antlya
, 2005
"... A generalized scheme for mapping stereo audio channels onto coding channels is considered in the paper. An improved joint stereo transform-based perceptual audio coder is proposed that employs this scheme instead of MS coding. The discussed frequency-dependent matrixing scheme uses a free rotation o ..."

A Method of Evaluating Mixed Reality of 3-dimensional Movie with Stereo Sound—An Application of Stabilometry
"... Abstract We measured the sway in the body’s centre of gravity (stabilometry) in 49 healthy men and women aged between 19 to 74 years who were standing in Romberg’s posture and watching a three-dimensional (3-D) movie that shoewed a roller coaster ride. Measurements were made under several conditions ..."

with a cusp, the patterns could be extracted by composing partial sequences in which the acceleration vectors were larger than a certain threshold value. Using these patterns, we attempted to evaluate the effect of 3-D movie with stereo sound on the equilibrial function.
Sequential Monte Carlo fusion of sound and vision for speaker tracking
, 2001
"... Video telephony could be considerably enhanced by provision of a tracking system that allows freedom of movement to the speaker, while maintaining a well-framed image, for transmission over limited bandwidth. Already commercial multi-microphone systems exist which track speaker direction in order to ..."

to reject background noise. Stereo sound and vision are complementary modalities in that sound is good for initialisation (where vision is expensive) whereas vision is good for localisation (where sound is less precise). Using generative probabilistic models and particle filtering, we show that stereo sound
Integrated Tracking with Vision and Sound
"... The research summarised here is working towards automatic control systems for cameras, in support of remote meetings. Progress is reported on several fronts: use of active contours to track heads, stereo sound analysis; applying particle filtering to handle both visual and aural clutter; and the use ..."

The instructive animation: Helping students build connections between words and pictures in multimedia learning
- Journal of Educational Psychology
, 1992
"... In 2 experiments, students studied an animation depicting the operation of a bicycle tire pump or an automobile braking system, along with concurrent oral narration of the steps in the process (concurrent group), successive presentation of animation and narration (by 4 different methods), animation ..."

are most effective when they occur contig-uously in time or space. Imagine an electronic encyclopedia in which a user sits in front of a screen and keyboard. The user simply types in a term (or selects it from a list), such as pump. Then a multi-media presentation begins, involving stereo sound and high
Data fusion for visual tracking with particles
- Proc. IEEE
, 2004
"... Abstract—The effectiveness of probabilistic tracking of objects in image sequences has been revolutionized by the development of particle filtering. Whereas Kalman filters are restricted to Gaussian distributions, particle filters can propagate more general distributions, albeit only approximately. ..."

. Although this fact has been acknowledged before, it has not been fully exploited within a visual tracking context. Here we introduce generic importance sampling mechanisms for data fusion and discuss them for fusing color with either stereo sound, for tele-conferencing, or with motion, for surveillance
Synthesized stereo combined with acoustic echo cancellation for desktop conferencing
- Bell Labs Tech. J
"... One promising application in modern communications is desktop conferencing, which can involve several participants over a widely distributed area. Synthesized stereophonic sound will enable a listener to spatially separate one remote talker from another and thereby improve understanding. In such a s ..."

scenario, we assume we are located in a hands-free environment where the compos-ite acoustic signal is presented over loudspeakers, thus requiring acoustic echo cancellation. In this paper, we explain some of the methods that can be used to synthesize stereo sound and how such methods can be combined
A Hybrid Mono/Stereo Acoustic Echo Canceller
- IEEE Trans. Speech Audio Processing.1997
"... Abstract—In many applications, such as teleconferencing, mul-timedia workstations, televideo gaming, etc., stereo sound is already, or will soon be, implemented to give spatial realism that mono systems cannot offer. In such hands-free systems, stereophonic acoustic echo cancelers are absolutely nec ..."
