But, since regular transceivers use significant amount of power for idle channel listening, all of these protocols have high overhead in power consumption when sensors need to work with asynchronous events triggered from outside the network, or have long sleep modes without any operation. Therefore, we introduce a protocol that works with our ultra low power receiver to deal with these events, while the rest of the sensors can be placed into off mode. We discuss possible application of the wake up receiver (and compare it with applications that do not use it) regarding the average power consumed for communication. Results show that using our low power wake up radio has significant advantages when the sensor has long sleep times.","PeriodicalId":444978,"journal":{"name":"2011 5th International Conference on Pervasive Computing Technologies for Healthcare (PervasiveHealth) and Workshops","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127963349","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}

Data gathered using these sensors has the potential to be converted into high quality motion data. By outfitting a subject with multiple WIMUs full motion data can be gathered. With a potential cost of ownership several orders of magnitude less than traditional camera based motion capture, WIMU systems have potential to be crucially important in supplementing or replacing traditional motion capture and opening up entirely new application areas and potential markets particularly in the rehabilitative, sports & at-home healthcare spaces. Currently WIMUs are underutilized in these areas. A major barrier to adoption is perceived complexity. Sample rates, sensor types & dynamic sensor ranges may need to be adjusted on multiple axes for each device depending on the scenario. As such we present an advanced WIMU in conjunction with a Smart WIMU system to simplify this aspect with 3 usage modes: Manual, Intelligent and Autonomous. Attendees will be able to compare the 3 different modes and see the effects of good and bad set-ups on the quality of data gathered in real time.","PeriodicalId":444978,"journal":{"name":"2011 5th International Conference on Pervasive Computing Technologies for Healthcare (PervasiveHealth) and Workshops","volume":"95 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126004724","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}

This is not only based on the latest advances in sensor technology but also due to the incorporation of more powerful communication and processing mechanisms into the sensor nodes which may, eventually, allow for the emergence of cognitive intelligence from within such networks themselves. Such platforms are collectively referred to as wireless sensor networks, which provide not only the capabilities to sense and to process information but also to act upon them, which allows to actively influence the underlying context. Consequently, future intelligent infrastructures will be largely based on sensor network technology that will provide the layers for contextual information gathering, knowledge processing as well as for adaptation and optimization mechanisms. This will pave the way for new types of application and services in the area of pervasive computing in healthcare and beyond that are fully autonomous in all aspects of their operations as well as their set-up and maintenance. This paper sketches the potential and challenges of future sensor networks that provide the foundations for self-adapting ambient intelligence and briefly discusses some of the requirements thereof.","PeriodicalId":444978,"journal":{"name":"2011 5th International Conference on Pervasive Computing Technologies for Healthcare (PervasiveHealth) and Workshops","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116816529","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}

Envisage gait rehabilitation is a study involving a rehabilitation aid that proposes to provide stroke survivors, and their therapists, with accurate visual feedback of their movement performance during gait-related exercises.

We propose a novel and practical solution using three small wearable wireless Functional Activity Monitor (FAM) sensors and a smartphone to store, transmit, analyze and update data. Three sensors, each composed of a tri-axial accelerometer and a tri-axial gyroscope, are attached to the chest and both thighs. A computationally efficient signal processing algorithm is designed to accurately measure tilting angles. A continuous activity recognition algorithm is developed using a decision tree based on time series data and spectrum analysis; this algorithm can identify activities of daily life in three general categories: (1) postures such as standing, sitting, and lying; (2) locomotion such as walking; and (3) transitions such as sit-to-stand and stand-to-sit. The results show an accurate angle measurement compared to the motion capture system Optotrak 3020 and a reliable detection of all activities with sensitivity at least 96.2% compared to video recordings.","PeriodicalId":444978,"journal":{"name":"2011 5th International Conference on Pervasive Computing Technologies for Healthcare (PervasiveHealth) and Workshops","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133074650","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}

One of the most serious challenges is the maintenance of the area-wide supply chain of medical care despite the threatening shortage of physicians. In this context, telemedical services for communication between doctors and patients gain in importance. Crucial for the success of such electronic services is the choice of the medium, which must be appropriate for this special purpose of use and, finally, accepted by its users. In this paper, an exploratory survey was conducted to detect acceptance motives of five different media (face-to-face, telephone, videophone, video conference, interactive wall) in two different usage situations. 103 respondents participated (17-83 years). Findings show that for the standard case, a face-to-face consultation is still highly preferred compared to any telemedical applications. For emergency situations, participants' attitudes change: A telephone consultation was similarly well accepted than face-to-face communication. As the most comfortable service a face-to-face-consultation was corroborated, followed by the videophone consultation.","PeriodicalId":444978,"journal":{"name":"2011 5th International Conference on Pervasive Computing Technologies for Healthcare (PervasiveHealth) and Workshops","volume":"180 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133473204","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}
