It is based on passive RFID tags which embed the coordinate (x, y, floor). According to psychological model of spatial navigation and the requirements of rehabilitation professionals, PDAs prompting with spatial photos at the right time and place can assist cognitively-impaired persons with navigating indoors or on the road. To do so, passive RFID tags which can be imagined as a new traffic sign system, are posted to selected positions on routes. The navigational photos are served on demand to the user who uses the built-in RFID reader to sense the RFID tag when it is in eyesight range. A tracking function is integrated to timestamp the visited positions and issue alerts in case of anomalies. The tracking system increases the sense of security and also lowers the entry threshold to accepting the assistive technology. A prototype which consists of wayfinding devices and a tracking system, is designed and tested on a university campus. Compared to the sensor network approach, RFID tags are easier and faster to deploy and the cost is lower. The experimental results show the computer-human interface is friendly and the capabilities of wayfinding are reliable.","PeriodicalId":313776,"journal":{"name":"2008 Second International Conference on Pervasive Computing Technologies for Healthcare","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133692256","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Continuous physiological information such as ECG, heart rate, activity profile and energy expenditure can be derived from a single waist mounted activity monitor. This information when translated into clinically relevant measures, not only reflects patients condition in a similar way as convention tools but also shows the continuous status of functional capacity. In this paper, various such clinically relevant measures which can be derived from acceleration and ECG signals are described.","PeriodicalId":313776,"journal":{"name":"2008 Second International Conference on Pervasive Computing Technologies for Healthcare","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130528652","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, a notification without regard to their context may cause a medical error. To reveal the dependency between suitable information display methods and such parameters as nursing duties and the immediacy of advice, an experimental study with simulated patients was conducted in which 38 real nurses wearing an information display device on their wrists were asked to perform several nursing duties. Based on an analysis of questionnaires and the distribution of nurse response times after receiving the notification, we established guidelines for a context-aware notification system for nursing. By developing a system based on these guidelines, the system can safely display advice in a feasible and effective manner.","PeriodicalId":313776,"journal":{"name":"2008 Second International Conference on Pervasive Computing Technologies for Healthcare","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130787157","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The ability to provide readily access to integrated healthcare services remotely is now essential. Although Grid technology can support the integration of healthcare services across settings of care and among providers of care, it doesnpsilat make these services available to authorized users at the point of care when needed. The integration of mobile and wireless devices with Grid technology can provide ubiquitous and pervasive access to Grid services. This paper presents HDGPortal, a Grid portal application which provides access to workflow-based healthcare processes using wireless Personal Digital Assistants (PDAs). HDGPortalpsilas architecture is based on wrapping the workflow applications as web services and web service resources. These services are available to users through a number of Grid portal components that can be used for workflow enactment.

To overcome such a difficulty, a method, called VACA (vote-and-chain algorithm) is proposed to obtain an approximate HRV measurement. With VACA, the contaminated ECGs can be patched to obtain HRV metric, such as SDNN, even when the arrival rate of noises has reached the same level of heart rate. The performance of this algorithm is evaluated with 27,000 contaminated ECGs which are synthesized by real ECGs in the Physio-Net and noises of Poisson process. The best parameters for VACA are explored so that it can reach an accuracy of (100plusmn20)% for 97% of the 27000 contaminated ECG data. The experiment results show that VACA is an robust method for HRV measurement in applications that long-term multi-lead ECG is not feasible.","PeriodicalId":313776,"journal":{"name":"2008 Second International Conference on Pervasive Computing Technologies for Healthcare","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127806711","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we propose a calibration algorithm which can relate both coordinate systems without performing actual measurements of the position of reference points in the room. The calibration tool is constructed such that it can be operated by any caregiver and hence eases the deployment of the home monitoring appliances. Our method (semi)automatically detects a plane corresponding to the ground floor in the three dimensional images. Random points from that plane are used to calculate rotation angles in a least squares manner.
