KinRes: depth sensor noise reduction in contactless respiratory monitoring 非接触式呼吸监测中的深度传感器降噪
Kaveh Bakhtiyari, J. Ziegler, H. Husain
This paper proposes a novel reliable solution, named KinRes, to extract contactless respiratory signal via an IR-3D Depth sensor (Microsoft Kinect 2) on human subjects interacting with a computer. The depth sensor is very sensitive to the minor changes so that the body movements impose noise in the depth values. Previous studies on contactless respiratory concentrated solely on the still laid subjects on a surface to minimize the possible artifacts. To overcome these limitations, we low-pass filter the extracted signal. Then, a greedy self-correction algorithm is developed to correct the false detected peaks & troughs. The processed signal is validated with a simultaneous signal from a respiratory belt. This framework improved the accuracy of the signal by 24% for the subjects in a normal sitting position.
本文提出了一种新颖可靠的解决方案,名为KinRes,通过IR-3D深度传感器(微软Kinect 2)在与计算机交互的人类受试者上提取非接触式呼吸信号。深度传感器对微小的变化非常敏感,因此人体运动在深度值中施加噪声。以前对非接触呼吸的研究仅仅集中在静止放置在表面上的受试者上,以尽量减少可能的伪影。为了克服这些限制,我们对提取的信号进行低通滤波。然后,提出了一种贪婪自校正算法来校正误检的波峰和波谷。处理后的信号与来自呼吸带的同步信号进行验证。对于处于正常坐姿的受试者,该框架将信号的准确性提高了24%。

Endocrine econsults improve access to care for the underserved 内分泌咨询改善了缺医少药人群获得护理的机会
N. Minsky, R. Tamler
The endocrinology eConsult service at Mount Sinai Hospital, in New York City, was conceived to simplify and accelerate access to the expertise of endocrinologists. Here we detail how we designed our workflow according to input from primary care providers (PCPs). Additionally, we describe the impact of the pilot phase of our endocrinology eConsult service. In this pilot phase, providers in a Medicaid clinic and those making visits to homebound patients placed eConsult orders within the hospital's EMR using one of 18 original, disease-specific templates and one generic template. The eConsultant sent evidence-based recommendations in a response template, which included a rationale with references. As part of an ongoing quality improvement project, PCPs were asked to complete a two question closeout survey. Seventy percent of PCPs indicated that they got good advice for a new or additional course of action, and 25% answered that they were able to confirm a course of action that they already had in mind. Referral was originally contemplated, but avoided as a result of the eConsult according to 62% of respondents, exceeding rates reported at other academic institutions. Our unique emphasis on providing a detailed rationale for recommendations may have contributed to these outcomes. With a majority of respondents indicating that a formal consultation was averted, an expanded endocrine eConsult service could reduce a significant volume of unnecessary endocrine referrals, expedite more urgent visits, and reduce costs. This outcome is especially significant in light of a nationwide shortage of endocrinologists.
纽约市西奈山医院的内分泌咨询服务旨在简化和加速获得内分泌学家的专业知识。在这里,我们详细介绍了如何根据初级保健提供者(pcp)的输入来设计我们的工作流程。此外,我们描述了我们的内分泌咨询服务的试点阶段的影响。在这个试点阶段,医疗补助诊所的提供者和那些访问居家患者的人使用18个原始的疾病特定模板和一个通用模板中的一个在医院的电子病历中放置eConsult订单。咨询顾问在回应模板中发送了基于证据的建议,其中包括参考资料的基本原理。作为正在进行的质量改进项目的一部分,pcp被要求完成一项包含两个问题的结案调查。70%的pcp表示,他们对新的或额外的行动方案得到了很好的建议,25%的人回答说,他们能够确认他们已经考虑过的行动方案。根据62%的受访者,最初考虑转诊,但由于咨询结果而避免转诊,超过其他学术机构报告的比率。我们独特地强调为建议提供详细的理由,这可能促成了这些结果。由于大多数答复者表示避免了正式咨询,扩大内分泌咨询服务可以减少大量不必要的内分泌转诊,加快更多的紧急访问,并降低成本。鉴于全国范围内内分泌学家的短缺,这一结果尤为重要。

Ontological modeling of motivational messages for physical activity coaching 体育训练动机信息的本体建模
Claudia Villalonga, H. O. D. Akker, H. Hermens, L. Herrera, H. Pomares, I. Rojas, O. Valenzuela, O. Baños
Smart coaching systems are named to play a central role in both prevention and intervention strategies for behavioral change. While relevant progresses have been made in terms of automatic and continuous monitoring of behavioral aspects, e.g. amount and variety of physical activity, coaching and feedback techniques are still in an infancy stage. Current smart coaching strategies are mostly based on handcrafted messages which hardly personalize to the needs, context and preferences of each user. In order to make these recommendations more realistic, engaging and effective more flexible and sophisticated strategies are needed. This paper presents an ontology-based approach to model personalizable motivational messages for promoting healthy physical activity. The proposed ontology not only models the message intention and its components, e.g. argument, feedback or followup, but also its content, i.e. action, place, time or object required to perform the recommended activity. Through this ontology the messages can also be categorized into multiple classes, e.g. sedentary, mild or vigorous activities, and retrieved based on the preferences, needs and context of the user. Additional information not explicitly present on the messages can be inferred from the ontology by applying reasoning techniques and used to enhance the message retrieval process.
智能教练系统被命名为在行为改变的预防和干预策略中发挥核心作用。虽然在自动和持续监测行为方面取得了相关进展,例如体育活动的数量和种类,但指导和反馈技术仍处于起步阶段。目前的智能教练策略大多是基于手工制作的信息,几乎没有个性化的需求,背景和每个用户的偏好。为了使这些建议更现实、更有吸引力和更有效,需要更灵活和复杂的战略。本文提出了一种基于本体的方法来建模个性化的激励信息,以促进健康的身体活动。提出的本体不仅对消息意图及其组成部分(如争论、反馈或后续行动)建模,还对其内容(如执行推荐活动所需的动作、地点、时间或对象)建模。通过这个本体,消息也可以被分类为多个类别,例如久坐、轻度或剧烈的活动,并根据用户的偏好、需求和上下文进行检索。可以通过应用推理技术从本体中推断出未显式呈现在消息上的其他信息,并用于增强消息检索过程。

Is fitbit fit for sleep-tracking?: sources of measurement errors and proposed countermeasures fitbit适合睡眠追踪吗?:测量误差的来源及提出的对策
Zilu Liang, Bernd Ploderer, Mario Alberto Chapa Martell
It is now easy to track one's sleep through consumer wearable devices like Fitbit from the comfort of one's home. However, compared to clinical measures, the data generated by such consumer devices is limited in its accuracy. The aim of this paper is to explore how users perceive accuracy issues, possible measurement errors and what can be done to address these issues. Through an interview study with 14 Fitbit users we identified three main sources of errors: (1) lack of definition of sleep metrics, (2) limitations in underlying data collection and processing mechanisms, and (3) lack of rigor in tracking approach. This paper proposes countermeasures to address these issues, both from the aspect of technological advancement and through engaging end-users more closely with their data.
现在,通过Fitbit等消费者可穿戴设备,人们很容易在舒适的家中跟踪自己的睡眠情况。然而,与临床测量相比,这种消费设备产生的数据在准确性上是有限的。本文的目的是探讨用户如何感知精度问题,可能的测量误差,以及可以做些什么来解决这些问题。通过对14位Fitbit用户的访谈研究,我们确定了三个主要的错误来源:(1)缺乏睡眠指标的定义,(2)底层数据收集和处理机制的局限性,以及(3)跟踪方法缺乏严谨性。本文提出了解决这些问题的对策,无论是从技术进步方面,还是通过让最终用户更密切地接触他们的数据。

Addressing medication management for older people with multimorbidities: a multi-stakeholder approach 解决老年多重疾病患者的药物管理问题:多方利益相关者方法
Julie Doyle, E. Murphy, Suzanne Smith, C. Hannigan, J. Kuiper, A. Jacobs, J. Dinsmore
Multimorbidity, the presence of two or more chronic conditions, places a significant burden on health systems globally. People managing multiple chronic conditions face burdensome and complex treatment plans. Polypharmacy, the prescription of several drugs, is typical in this cohort, adding to the treatment burden and potentially resulting in dangerous drug interactions. The goal of our work is to design a medication management application for older people with multimorbidity, and those within their care ecosystem. In this paper we present findings from interviews and focus groups with 124 participants, including older adults, informal and formal carers, and healthcare professionals. We outline six design requirements and describe how our design process is grounded in a strong, theoretical behaviour change approach that will allow us to fully evaluate the effectiveness of our design for medication management for those with multimorbidity, supported by their care network.
多重发病,即存在两种或两种以上慢性病,给全球卫生系统带来了重大负担。患有多种慢性疾病的人面临着繁重而复杂的治疗计划。多重用药,即多种药物的处方,在这一队列中是典型的,增加了治疗负担,并可能导致危险的药物相互作用。我们工作的目标是为患有多种疾病的老年人设计一个药物管理应用程序,以及那些在他们的护理生态系统中的应用程序。在本文中,我们介绍了124名参与者的访谈和焦点小组的调查结果,包括老年人,非正式和正式的护理人员以及医疗保健专业人员。我们概述了六个设计要求,并描述了我们的设计过程是如何建立在一个强大的理论行为改变方法的基础上的,这将使我们能够充分评估我们设计的药物管理的有效性,这些药物管理是针对那些患有多种疾病的人的,并得到他们的护理网络的支持。

Benefits and costs of patient generated data, from the clinician's and patient's perspective 从临床医生和患者的角度来看,患者生成数据的收益和成本
Heleen Rutjes, M. Willemsen, Janne van Kollenburg, S. Bogers, W. Ijsselsteijn
In the relation between patient and clinician, communication is a central aspect. In this short paper, we conceptualize patient-generated data (PGD) as a means of communication. We present a case study in which we explore the experiences of clinicians and patients with PGD. We identify and discuss some real-world trade-offs in using PGD both effectively and meaningfully in clinical practice. Our key finding is that data collection and sharing is about a lot more than the data itself, and that a process of collective meaning making is required to focus on clinically relevant information, and to ground the communication in a sufficiently shared understanding of the subjective experiences associated with objective data points.
在医患关系中,沟通是一个中心方面。在这篇短文中,我们将患者生成数据(PGD)概念化为一种通信手段。我们提出了一个案例研究,其中我们探讨临床医生和PGD患者的经验。我们确定并讨论了在临床实践中有效和有意义地使用PGD的一些现实世界的权衡。我们的主要发现是,数据收集和共享不仅仅是数据本身,而且需要一个集体意义形成的过程来关注临床相关信息,并将交流建立在对与客观数据点相关的主观经验的充分共享理解之上。

Automated speech-based screening for alzheimer's disease in a care service scenario 在护理服务场景中,基于语音的阿尔茨海默病自动筛查
J. Tröger, N. Linz, J. Alexandersson, A. König, P. Robert
This paper describes a benchmark study for a lightweight and low-cost dementia screening tool. The tool is easy to administer, requires no additional experimentation material, and automatically evaluates and indicates potential subjects with dementia. The protocol foresees that subjects answer four distinct tasks, three of which are ordinary questions and one is a counting prompt. In our care use case, older people are assessed remotely via the tool, potentially even via telephone or within a daily care service routine. The assessment results are subsequently sent to professionals who initiate further steps. A machine learning classifier was trained on the French Dem@Care corpus. Solely utilizing vocal features, the classifier reaches 89% accuracy. Implications for the use case and further steps are discussed.

Fostering user engagement: improving sense of identity through cosmetic customization in wearable trackers 促进用户参与:通过可穿戴追踪器的外观定制提高认同感
Jin Kang, Jomara Bindá, Pratik Agarwal, B. Saconi, E. Choe
Despite numerous health advantages wearable health trackers could offer, tracker users often abandon their devices after a short period of time. One reason for abandonment is users' lack of identification of their trackers as an accurate reflection of who and what they are (i.e., sense of identity). In this study, we examine the role of cosmetic customization (i.e., a modification of a given product's presentation) of a wearable health tracker in increasing one's sense of identity. Furthermore, we explore if one's sense of identity can explain the relationship between cosmetic customization and user engagement (assessed by attitude, exercise intention, and sense of attachment) with a wearable tracker. We conducted a between-subjects online experiment and found that individuals presented with a high level of cosmetic customization features experienced a higher sense of identity with a wearable health tracker, which in turn was associated with more favorable attitude, higher exercise intention, and greater sense of attachment towards the tracker than individuals presented with a low level of cosmetic customization features. Based on the study results, we recommend the designers of wearable health trackers to provide users with salient and recognizable cosmetic customization features so that users can establish a good "identity fit" with their tracker.
尽管可穿戴式健康追踪器可以提供许多健康方面的好处,但追踪器用户往往会在短时间内放弃他们的设备。放弃的一个原因是用户缺乏对追踪器的识别,无法准确地反映他们是谁和他们是什么(即认同感)。在这项研究中,我们研究了可穿戴健康追踪器的化妆品定制(即修改给定产品的外观)在增加个人认同感方面的作用。此外,我们探讨了一个人的认同感是否可以解释化妆定制与用户参与(通过态度、运动意图和依恋感来评估)之间的关系。我们进行了一项被试之间的在线实验,发现具有高水平化妆品定制功能的个体对可穿戴健康追踪器有更高的认同感,而这反过来又与具有低水平化妆品定制功能的个体对可穿戴健康追踪器有更积极的态度、更高的运动意愿和更大的依恋感相关。根据研究结果,我们建议可穿戴健康追踪器的设计者为用户提供显著的、可识别的化妆品定制功能,让用户与他们的追踪器建立良好的“身份契合”。

Based on the study results, we recommend the designers of wearable health trackers to provide users with salient and recognizable cosmetic customization features so that users can establish a good \"identity fit\" with their tracker.","PeriodicalId":200810,"journal":{"name":"Proceedings of the 11th EAI International Conference on Pervasive Computing Technologies for Healthcare","volume":"225 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115492640","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}

Automated passive sensing applications and self-reported smart diaries seem to hold promise for the management of anxiety in autism and other mental health conditions. However, passive sensing often struggles with noisy data, ambiguous feedback and weak user agency over the device, whilst self-reporting relies on user-entered data which can be time consuming and cognitively demanding. To address these limitations, we explore a different approach, whereby individuals consciously actuate personal data capture and are in control of it at all times; yet, the interaction solely involves clicking a button, thus avoiding cognitive overload whilst supporting immediate reflection. We call this approach intentive computing. Through our initial investigations we found that conscious interactions cannot only provide real-time relief in anxiety management, but can also function as memory anchors irrespective of the content captured and even prior to data visualization.
自动被动感知应用程序和自我报告的智能日记似乎有望管理自闭症和其他精神健康状况的焦虑。然而,被动感知经常与嘈杂的数据、模糊的反馈和设备上的弱用户代理作斗争,而自我报告依赖于用户输入的数据,这可能是耗时和认知要求。为了解决这些限制,我们探索了一种不同的方法,即个人有意识地激活个人数据捕获并始终控制它;然而,交互只涉及点击一个按钮,从而避免认知过载,同时支持即时反射。我们称这种方法为意图计算。通过我们的初步调查,我们发现有意识的互动不仅可以在焦虑管理中提供实时缓解,而且还可以作为记忆锚点,而不考虑捕获的内容,甚至在数据可视化之前。
