By frequent and intense physical therapy, these patients can sustain or even enhance their functional performance. However, physical therapy, whether or not it is supported by technology, can currently only be followed in a rehabilitation centre under supervision of a therapist. To provide technology-supported physical therapy for independent use by the patient in the home situation, our current research explores pervasive technologies for rehabilitation systems. In this paper, we describe our pervasive prototype 'Liftacube' for training of upper extremities. An initial evaluation with patients with a neurological disorder or spinal cord injury (CVA and paraplegia patients) and their therapists reveals a great appreciation for this motivating pervasive gaming prototype. Reflections on the technical set-up (such as size, form factor, and materials) and interaction preferences (such as feedback, games, and movements for interaction) for pervasive rehabilitation systems in a residential environment are elaborated upon.","PeriodicalId":91811,"journal":{"name":"The ...

This paper discusses two service platforms that monitor user's physical activity through wearable sensors and that present the user personalised feedback. Important principles for effectiveness of such systems are personalisation or tailoring, context-awareness, feedback and interaction. We focus here on the presentation of feedback to the user. We present results of a number of short and long term user studies in which we compare different forms of feedback presentation: text, graphics and with or without an anthropomorphic graphical talking character. Results show that although some users like the talking character they don't have a positive effect on adherence to the activity program. The outcomes of the user evaluations support our beliefs that personal motivation is of primary importance for the effectiveness of these systems. Technical challenges ahead are to support more personal and context-aware feedback, more variations as well as the possibility for more interaction with the coaching system.","PeriodicalId":91811,"journal":{"name":"The ...

The increase in the use of context-aware technologies has sparked growth in assistive applications and there is now a need to enable the adaptation of such technologies to reflect the changes in user behaviors. This paper describes the conceptualization and development of a personalization mechanism that can be integrated into a context-aware application for the purposes of providing an adaptable, mobile-based service to a user. We highlight the use of an ontological User Profile Model to provide a detailed representation of a user for use within adaptive applications. Special emphasis is placed on the use of rule-based reasoning using the Semantic Web Rule Language (SWRL). The paper details how these rules are created and used alongside the User Profile for the purposes of application personalization. We present a case study to illustrate the use of SWRL within the User Profile Model. Specifically, the case study focuses on providing personalized travel assistance to older users, with the use of self-service ticket machines via an `on-demand' context-aware smart-phone.","PeriodicalId":91811,"journal":{"name":"The ...

Accumulated various pollutants at inner duct surface can cause secondary air contamination and injure subway passengers' respiratory system and health. In fact, periodic duct cleaning works can improve indoor air quality, but cleaning entire ventilation system takes high cost and manpower. This study addresses the effectiveness of duct cleaning based on the developed autonomous duct cleaning robot. In particular, the new duct cleaning robot equipped with compliance rolling brushes enables to operate robot in a constant cleaning force to the target duct surface. Control method with the compliant device has also been analyzed. The proposed design of autonomous duct cleaning robot is expected to save the operating cost of subway ventilation system and sustain clean indoor air quality by providing easier and faster cleaning tools.","PeriodicalId":91811,"journal":{"name":"The ...

Long term temporal measurements can also assist in monitoring the user for either emergencies or long term mood instabilities. Current article presents research work on the computational formalization and analysis of full body 3D expressivity in Natural (bodily) Interaction within the framework of Pervasive Assistance. Expressivity dimensions are selected as the most complete approach to body expressivity modeling, since they cover the entire spectrum of expressivity parameters related to emotion and affect. In this study five expressivity parameters are computationally formalized, using different approaches based on silhouette, limbs position and joints rotation, for each expressivity feature. These approaches are then evaluated in terms of their effectiveness in modeling the expressivity aspect in question. The modeling effectiveness of each approach is assessed using Linear Discriminant Analysis (LDA) and its coefficients on the automatically extracted parameters, defined in the computational formalization, against an experimental dataset consisting of extreme expressions (positive and negative) of the investigated expressivity aspects. The The experimental results confirm that the proposed Fading Silhouette Motion Volumes (FMSV) approach, is the most effective in modeling body expressivity.","PeriodicalId":91811,"journal":{"name":"The ...

PD symptoms such as tremor, rigidity, bradykinesia and gait disturbances can be alleviated with drug treatments or deep brain stimulation; however, these treatments need to be appropriately adjusted over time. Monitoring the disease severity during intermittent physician visits for this purpose is notoriously imprecise. Remote and continuous monitoring of the severity of parkinsonism in these patients could therefore significantly improve the patient's health and quality of life. In recent work, we showed it is possible to discriminate between varying levels of parkinsonism and normal brain activity, based on motor cortex electroencephalograms (EEGs). We believe it may be possible to detect similar patterns in ambulatory human EEGs collected periodically during home health care visits. In this study, we investigate how these EEG readings can be used together with continuous smartphone gyroscope and accelerometer movement measurements to allow improved management of Parkinson's Disease treatments.","PeriodicalId":91811,"journal":{"name":"The ...

First, we introduce our Microsoft Kinect--based video dataset of American Sign Language (ASL) signs designed for body part detection and tracking research. This dataset allows researchers to experiment with using more than 2-dimensional (2D) color video information in gesture recognition projects, as it gives them access to scene depth information. Not only can this make it easier to locate body parts like hands, but without this additional information, two completely different gestures that share a similar 2D trajectory projection can be difficult to distinguish from one another. Second, as an accurate hand locator is a critical element in any automated gesture or sign language recognition tool, this paper assesses the efficacy of one popular open source user skeleton tracker by examining its performance on random signs from the above dataset. We compare the hand positions as determined by the skeleton tracker to ground truth positions, which come from manual hand annotations of each video frame. The purpose of this study is to establish a benchmark for the assessment of more advanced detection and tracking methods that utilize scene depth data. For illustrative purposes, we compare the results of one of the methods previously developed in our lab for detecting a single hand to this benchmark.","PeriodicalId":91811,"journal":{"name":"The ...

The model has been calibrated according to the specific indoor environment that is being monitored. Human segmentation is implemented using a standard established technique. The fisheye camera used for video acquisition is modeled using a spherical element, while the parameters of the camera model are determined only once, using the correspondence of a number of user-defined landmarks, both in real world coordinates and on the acquired video frame. Subsequently, each pixel of the video frame is inversely mapped to the direction of view in the real world and the relevant data are stored in look-up tables for very fast utilization in real-time video processing. The proposed fisheye camera model enables the inference of possible real world positions of a segmented cluster of pixels in the video frame. In this work, we utilize the constructed camera model to achieve a simple geometric reasoning that corrects gaps and mistakes of the human figure segmentation. Initial results are also presented for a small number of video sequences, which prove the efficiency of the proposed method.","PeriodicalId":91811,"journal":{"name":"The ...
