It is characterized by problems of paying attention, excessive activity, or difficulty controlling behavior which is not appropriate for a person’s age. Currently, as ADHD lacks of clear specificity, diagnosis of ADHD still mainly depends on doctors’ experiences and observation. Moreover, the monotonous environment of hospital may makes children feel nervous, which can lead to misdiagnosis. To cope with this problem, we design a contextualized and objective system to support auxiliary diagnosis of ADHD, which has eleven diagnostic scenarios designed according to the description of typical symptoms of ADHD in Diagnostic and Statistical Manual of Mental Disorders (DSM-V). During the testing, multi-source data are acquired, including physiological sensors’ data, motion sensors’ data and tasks related data. Now, Our system is still a primary prototype. In the next, we plan to deploy it in the hospital and collect more data, and research on the auxiliary diagnosis accuracy.","PeriodicalId":137790,"journal":{"name":"2019 IEEE/ACM International Conference on Connected Health: Applications, Systems and Engineering Technologies (CHASE)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126583655","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 perform supervised learning on a set of features extracted from streaming kratom data gathered from wrist-worn biosensors deployed on participants over a period of several days.We extract several time domain features, define a period of intoxication post-use based on the existing literature, and compare four classifiers based on their accuracy, sensitivity, and specificity.

Real-time and accurate objective pain assessment help hospital staffs and caregivers decide the proper dosage of pain medication to be provided to a patient in a timely manner. The state-of-the-art automatic and objective pain assessment techniques in the literature can be classified into two main categories: physiological-based and behavioral-based. The first-class monitors the changes in patients' physiological data such as Electrocardiography (ECG), Electromyography (EMG), Photoplethysmography (PPG) to identify autonomic nervous system reactions to pain, while the second class utilizes behavioral reactions to pain such as techniques using computer vision-based techniques by extracting features from patients' head poses and facial expressions. Recent pain monitoring systems have become multi-modal meaning that they deploy a combination of both approaches to improve pain monitoring accuracy. Although such complex models are highly accurate in pain monitoring, they are more computationally intensive imposing feasibility limitations to implement them on wearable devices in terms of energy efficiency (battery life) as well as computation latency. A smart and self-aware system capable of adaptively making a decision at run-time in response to the changes in pain level and context can minimize energy consumption by dynamically offloading tasks to the gateway devices at the edge layer. For this reason, in this paper, a self-aware system is proposed for the continuous assessment of pain intensity at the edge layer. Using the BioVid heat pain dataset, our approach demonstrates a promising reduction in terms of energy consumption with a negligible accuracy loss compared with its non-adaptive counterpart.","PeriodicalId":137790,"journal":{"name":"2019 IEEE/ACM International Conference on Connected Health: Applications, Systems and Engineering Technologies (CHASE)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125201841","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}

Cough type detection is traditionally done by physical examination through hearing patients coughs in a clinical visit which is subjective and costly. This work tries to provide an objective comprehensive approach for cough type detection using an extensive set of acoustic features applied to the recorded audio from a relatively large population of both healthy subjects and patient with various pulmonary diseases and healthy controls. A total number of 5971 coughs (5242 dry and 729 wet) were collected from 131 subjects using Smartphone. Annotation was done using a crowd-source platform. Classification sensitivity and specificity values of 86% and 84% was achieved respectively which is the highest in literature to the best of our knowledge.","PeriodicalId":137790,"journal":{"name":"2019 IEEE/ACM International Conference on Connected Health: Applications, Systems and Engineering Technologies (CHASE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129015888","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 paper proposes and designs an augmented reality (AR) based system that aims to ease and improve the effectiveness of ABA, as well as to reduce its cost as the ABA can be performed in a clinic or at home with the support of the system. The system consists of three major components, including a web-based module, a HoloLens-based AR module, and a central control module.

This paper proposes a low-cost, unobtrusive, portable pressure sensor array (PSA) for analyzing and tracking the sleep quality based on parameters such as respiratory rate (RR), body movements (BM), in-bed time (IBT), and apnea episodes (AE). The pressure sensors are fabricated by stacking a layer of anti-static (velostat) material with two layers of conductive fabric. The pressure sensors are sealed with two laminating layers. A 32-bit cortex-M0+ based microcontroller is used for data acquisition. The data obtained is locally stored in a PC for processing and analysis. The respiratory rate is extracted by data pre-processing and frequency analysis with a fixed window segmentation.","PeriodicalId":137790,"journal":{"name":"2019 IEEE/ACM International Conference on Connected Health: Applications, Systems and Engineering Technologies (CHASE)","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133598757","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}

Instead, it is able to receive patient vital sign measurements from any patient physiological monitoring device connected to OpenICE, irrespective of the device manufacturer. Based on the received vital signs, MEWS calculates an overall score indicating the monitored patient’s current status and is intended to direct clinicians to patients showing signs of deteriorating conditions and hence needing immediate intervention. The implementation and deployment of the MEWS app on OpenICE presents a preliminary step to understand the challenge of establishing (data) interface protocols to enable medical device interoperability generally, and for RT-CDS applications in particular, and to establish requirements for bridging the gap of current industrial standardization activities in addressing this challenge.","PeriodicalId":137790,"journal":{"name":"2019 IEEE/ACM International Conference on Connected Health: Applications, Systems and Engineering Technologies (CHASE)","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128956563","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}
