Access to information in electronic forms is currently difficult for blind people, but electronic information, particularly hypermedia, provide great potential to overcome the difficult ies that blind people have in accessing information. The E.U. funded ACCESS Project is developing tools to facilitate user interfaces which will be adaptable to the needs of… (More)
Inexpensive wearable sensors are well-suited for the automatic recognition of many activities occuring in everyday life. But what about fast and involved movements such as those occuring in athletic sports? We tackle this question by studying the feasibility of using body-worn gyroscopes and acceleration sensors to recognize Tai Chi movements. To this end,… (More)
—We present an educational and research kit to support hands-on teaching and experience of real-time activity or gesture recognition from on-body sensors. The kit is comprised of: wireless wearable sensor nodes for motion and ECG sensing; software infrastructure for synchronized data acquisition from multiple sensors, data visualization, signal alignment,… (More)
In this paper, we describe completed and ongoing work towards an interactive multimedia system that will appeal to today's youth culture identified as most likely to adopt such novel mobile applications that combines music, dance and technology. We describe our work in the application of three types of successful movement recognition applied in the field of… (More)
This paper reports ongoing work in which low cost sensors are combined with high level gesture recognition for automatic training and analysis of Tai Chi. Various feature extraction methods are developed for the sensors and Hidden Markov Modeling is used to classify Tai Chi movements.
Electroencephalogram (EEG) signal plays an important role in E-healthcare system, especially the mental healthcare field. In order to improve access and quality of EEG data delivery, detect the mental depression and reduce the hardware cost, we present the design and application of a novel wearable EEG system. After the introduction of hardware, a novel… (More)
PURPOSE Computerized cognitive behavioral therapy (CCBT) has been shown to be efficacious. Moreover, CCBT can be enhanced by using physiological and activity sensors, but there is no evidence about the acceptability of all these tools. The objective of this study is to examine the efficacy, expectations, satisfaction, and ease of use of an Internet-based… (More)
