This thesis presents the data collection, annotation, and analysis for multiple participants engaged in planning meetings. In support of the analysis tasks, this thesis presents the multimedia Visualization for Situated Temporal Analysis for Macintosh (MacVisSTA) system. It supports the analysis of multimodal human communication through the use of video, audio, speech transcriptions, and gesture and head orientation data. The system uses a multiple linked representation strategy in which different representations are linked by the current time focus. MacVisSTA supports analysis of the synchronized data at varying timescales for coarse-to-fine observational studies. The hybrid architecture may be extended through plugins. Finally, this effort has resulted in encoding of behavioral and language data, enabling collaborative research and embodying it with the aid of, and interface to, a database management system.

We propose a multimodal annotation exchange format, based on the annotation graph formalism, which is supported by import and export routines in the respective tools.

The common element that runs through these data is the co-temporality of the multiple modes of behavior. In this paper, we present the multimedia Visualization for Situated Temporal Analysis

Results of our study suggest that gestures are better suited for multi-tasking situations because they are less interruptive than touch interaction to users' primary tasks and are subjectively preferred by users in certain situations.
Microencapsulation of a synthetic peptide epitope for HTLV-1 in biodegradable poly(D,L-lactide-co-glycolide) microspheres using a novel encapsulation technique

The antigen/polymer solution is emulsified in mineral oil containing sorbitan trioleate (Span 85) as an emulsifier and a low level of cottonseed oil to extract the TFA. Fluoresceinisothiocyanate-labelled bovine serum albumin (FITC-BSA) was used as a model antigen to characterize the microencapsulation. Microspheres were of the desired size (<10 microm) for targeting to antigen-presenting cells, and released the model antigen slowly after an initial burst release (11%) in PBS/0.02% Tween 80 at 37 degrees C. Subsequently, a potential peptide vaccine, designated MVFMF2, for the human T-lymphotropic virus type 1 (HTLV-1 ) was encapsulated at 4.7% loading using the novel oil-in-oil method. In vivo immune responses were examined in rabbits immunized with (i) encapsulated MVFMF2 together with encapsulated adjuvant (N-acetyl-glucosamine-3yl-acetyl-L-alanyl-D-isoglutamine, nor-MDP, (ii) encapsulated MVFMF2 without adjuvant, and (iii) free peptide with adjuvant. Inoculation of the encapsulated peptide produced an antibody response similar to that of the free peptide emulsified in adjuvant. Moreover, the elevated immune response elicited by the encapsulated peptide was observed without multiple booster immunizations and irrespective of whether an adjuvant was used. Additionally, the antibodies raised against both free and encapsulated MVFMF2 had similar affinities, as judged by competitive enzyme-linked immunosorbant assay (ELISA), indicating that the encapsulated peptide retained a significant fraction of its epitopes. Hence, these results demonstrate that peptide vaccines can be encapsulated in PLGA microspheres using a common carrier solvent for both the peptide and polymer, which produces a desirable immune response in the absence of an adjuvant.

CLEAR is an international effort to evaluate systems for the perception of people, their activities, and interactions. In its second year, CLEAR has developed a following from the computer vision and speech communities, spawning a more multimodal perspective of research evaluation. This paper describes the evaluation tasks, including metrics and databases used, and discusses the results achieved. The CLEAR 2007 tasks comprise person, face, and vehicle tracking, head pose estimation, as well as acoustic scene analysis. These include subtasks performed in the visual, acoustic and audio-visual domains for meeting room and surveillance data.
AVSS Multiple Camera Person Tracking Challenge Evaluation Overview

In order to continue supporting the development robust people tracking technologies, the first AVSS Multiple Camera Person Tracking (MCPT) Challenge Evaluation was established to provide data and evaluation resources for researchers to build Single Person Tracking (SPT) technologies. This special session will focus on the AVSS MCPT Challenge Evaluation which will include a description of the evaluation task, the i-LIDS Multiple-camera tracking scenario data set used for the evaluation, and presentations by the challenge evaluation participants describing their systems.

Head pose information infers the direction of attention of the subjects in video, therefore is valuable for video event analysis/indexing, especially in meeting room scenario. We are developing a multi-modal meeting room data analyzing system for studying meeting room interaction dynamics, in which head pose estimation is one of the key components. As each subject in the meeting room can be observed by a pair of stereo cameras, we do 2D head tracking for the subject in each camera, and the 3D coordinate of the head can be obtained by triangulation. The 3D head pose is estimated in one of the camera coordinate system, we develop a procedure to accurately convert the estimated 3D pose in the camera coordinate system to that in the world coordinate system. In the experiment, visualization of the estimated head pose and location in world coordinate system verifies the soundness of our design. The estimated head pose and 3D location of the subjects in the meeting room allows further analysis of meeting room interaction dynamics, such as F-formation, Floor-control[1], etc.

Change in control of the floor can happen through a number of mechanisms, including interruptions, delegation of the floor, and so on. This paper investigates floor control in multiparty meetings that are both audio and video taped; hence, we analyze patterns of speech (e.g., the use of discourse markers) and visual cues (e.g, eye gaze exchanges) that are often involved in floor control changes. Identifying who has control of the floor provides an important focus for information retrieval and summarization of meetings. Additionally, without understanding who has control of the floor, it is impossible to identify important events such as challenges for the floor. In this paper, we analyze multimodal cues related to floor control in two different meetings involving five participants each.

This peptide construct, designated MVFMF2, comprises amino acids (aa) 175-218 of gp46 linked by a four residue turn (GPSL) to a promiscuous T-cell epitope from the measles virus fusion protein (MVF, aa 288 -302). The peptide was structurally characterized by circular dichroism (CD) spectroscopy and was found to contain a-helical secondary structure. The immunogenicity of MVFMF2 in rabbits and mice was evaluated by direct ELISA and competitive ELISA using peptide constructs and the recombinant protein ACH-RE3 (aa 165-306). This peptide, when administered with adjuvant (N-acetyl-glucosamine-3yl-acetyl-L-alanyl-D-isoglutamine, nor-MDP) was immunogenic in an outbred population of both rabbits and mice. Furthermore, the peptide construct was encapsulated in biodegradable microspheres of poly(D,L-lactide-co-glycolide) to eliminate booster immunization and to examine adjuvant requirements. The data indicate that MVFMF2 shows enhanced immunogenicity when encapsulated in biodegradable microspheres. Inoculation of the encapsulated peptide produced a similar humoral response to that of the free peptide, but did not require the use of adjuvant. Elicited anti-rabbit and anti-mouse antibodies recognized whole viral preparations and the recombinant protein ACH-RE3 in ELISA assays. Additionally, inoculated rabbits exhibited enhanced reactivity to viral antigens by western blot compared to non-vaccinated controls. Although anti-rabbit and anti-mouse antibodies were capable of inhibiting syncytium formation at low dilutions, rabbits were not protected from cell-associated viral challenge. Future development of vaccines to HTLV-1 may need to incorporate the ability to elicit cell-mediated immune responses in order to protect against cell-associated viral infection.

It combines the simplicity, speed and flexibility of tracking without using explicit shape models with the ability to utilize domain knowledge and to apply various constraints characteristic of more elaborate model-based tracking approaches.
