Abstract

Automatic detection of the level of human interest is of high relevance for many technical applications, such as automatic customer care or tutoring systems. However, the recognition of spontaneous interest in natural conversations independently of the subject remains a challenge. Identification of human affective states relying on single modalities only is often impossible, even for humans, since different modalities contain partially disjunctive cues. Multimodal approaches to human affect recognition generally are shown to boost recognition performance, yet are evaluated in restrictive laboratory settings only. Herein we introduce a fully automatic processing combination of Active-Appearance-Model-based facial expression, vision-based eye-activity estimation, acoustic features, linguistic analysis, non-linguistic vocalisations, and temporal context information in an early feature fusion process. We provide detailed subject-independent results for classification and regression of the Level of Interest using Support-Vector Machines on an audiovisual interest corpus ( AVIC ) consisting of spontaneous, conversational speech demonstrating "theoretical" effectiveness of the approach. Further, to evaluate the approach with regards to real-life usability a user-study is conducted for proof of "practical" effectiveness.

Abstract

BACKGROUND: In a patient with severe hemiplegia, the risk of the knee giving way is high during the early stage of gait exercise with an ankle-foot orthosis. However, use of a knee-ankle-foot orthosis has many problems such as large amount of assistance and compensatory motions. To resolve these problems, we have engaged in the development of the Gait Exercise Assist Robot (GEAR). OBJECTIVE: To evaluate the improvement efficiency of walk with GEAR in a stroke patient. METHODS: The subject was a 70-year-old man presented with left thalamus hemorrhage and right hemiplegia. The patient underwent exercise with the GEAR 5 days a week, for 40 minutes per day. We evaluated the Functional Independence Measure score for walk (FIM-walk score) every week. The control group consisted of 15 patients aged 20-75 years with hemiplegia after primary stroke, who had equivalent walking ability with the subject at start. As the primary outcome, we defined improvement efficiency of FIM-walk, which was gain of FIM-walk divided the number of required weeks. RESULTS: Improvement efficiency of FIM-walk of the subject was 1.5, while that of control group was 0.48±3.2 (mean±SD). CONCLUSIONS: GEAR is potentially useful for gait exercise in hemiplegic patients. [ABSTRACT FROM AUTHOR]

4. A bio-inspired predictive sensory-motor coordination scheme for robot reaching and preshaping.

Abstract

Abstract   This paper presents a sensory-motor coordination scheme for a robot hand-arm-head system that provides the robot with the capability to reach an object while pre-shaping the fingers to the required grasp configuration and while predicting the tactile image that will be perceived after grasping. A model for sensory-motor coordination derived from studies in humans inspired the development of this scheme. A peculiar feature of this model is the prediction of the tactile image. The implementation of the proposed scheme is based on a neuro-fuzzy module that, after a learning phase, starting from visual data, calculates the position and orientation of the hand for reaching, selects the best-suited hand configuration, and predicts the tactile feedback. The implementation of the scheme on a humanoid robot allowed experimental validation of its effectiveness in robotics and provided perspectives on applications of sensory predictions in robot motor control.

17. Intelligent Audio Analysis

Author

Subjects
Signal processing--Digital techniques--Data processing
Abstract

This book provides the reader with the knowledge necessary for comprehension of the field of Intelligent Audio Analysis. It firstly introduces standard methods and discusses the typical Intelligent Audio Analysis chain going from audio data to audio features to audio recognition. Further, an introduction to audio source separation, and enhancement and robustness are given. After the introductory parts, the book shows several applications for the three types of audio: speech, music, and general sound. Each task is shortly introduced, followed by a description of the specific data and methods applied, experiments and results, and a conclusion for this specific task. The books provides benchmark results and standardized test-beds for a broader range of audio analysis tasks. The main focus thereby lies on the parallel advancement of realism in audio analysis, as too often today's results are overly optimistic owing to idealized testing conditions, and it serves to stimulate synergies arising from transfer of methods and leads to a holistic audio analysis.

Abstract

Mechatronics for Safety, Security and Dependability in a New Era contains selected leading papers from the International Conference on Machine Automation 2004, the work of researchers from USA, Japan, China and Europe. The topics covered include: manufacturing systems such as CAD/CAM, machining and, human factors in manufacturing; robotics in relation to sensors and actuators, new control technology and, measuring and monitoring; the application of new technologies in connection with wireless communication, human behavior analysis and welfare. Mechatronics has been rapidly developing as an important area that affects all areas of society from industrial robots, automobiles, electrical appliances, computers and consumer goods etc. It also plays a role in safety recovery, such as for rescue tasks after disasters, destruction of hazardous and abandoned weapons and the restoration of polluted environments. The increasing need for safe, secure and dependable technology means that the advancement of mechatronics plays an essential role in the development of products and systems. This book provides an insight into developments in essential new methodologies and tools to design and to build machines to achieve this. - Covers key topics in manufacturing, such as machining, robotics, sensors, monitoring, etc. - Reviews modern applications of new technologies in connection with wireless communication, human behavior analysis, and welfare
