Self-efficacy theory as a framework for interventions that support parents of NICU infants 自我效能理论作为支持新生儿重症监护病房婴儿父母的干预框架
Y. S. Lee, C. Garfield, H. N. Kim
Transitioning a Very Low Birth Weight (VLBW) premature infant from the Neonatal Intensive Care Unit (NICU) to home is a very stressful task for parents. Few studies examined the needs of parents of VLBW infants during the transition; moreover, even less is known about technology development strategies that aim to increase the parenting confidence. In this study, we used Bandura's self-efficacy theory as a framework to understand ways to develop successful interventions for parents of VLBW infants. The self-efficacy theory posits that parenting behavior and the quality of care can be improved by supporting the four major sources of self-efficacy: mastery experiences, vicarious experiences, social persuasion, and physiological responses. We describe self-efficacy theory and its role in the development of technology interventions to support parents of NICU infants using a case study, called NICU-2-HOME.
将极低出生体重(VLBW)早产儿从新生儿重症监护病房(NICU)转移回家对父母来说是一项非常有压力的任务。很少有研究调查过超低体重婴儿在过渡时期父母的需求;此外,人们对旨在提高父母信心的技术发展策略所知甚少。在本研究中,我们以Bandura的自我效能理论为框架来了解如何为VLBW婴儿的父母制定成功的干预措施。自我效能理论认为,通过支持自我效能感的四个主要来源:掌握体验、替代体验、社会说服和生理反应,可以改善父母的行为和护理质量。我们描述自我效能理论及其在技术干预发展中的作用,以支持新生儿重症监护病房婴儿的父母使用一个案例研究,称为NICU-2- home。

Passive, in-home gait measurement using an inexpensive depth camera: Initial results 使用廉价深度相机进行被动的家庭步态测量:初步结果
Erik E. Stone, M. Skubic
In-home gait measurement results from the apartments of seven older adults obtained using an environmentally mounted depth camera, the Microsoft Kinect, are presented. Previous work evaluating the use of the Kinect for in-home gait assessment in a lab setting has shown the potential of this approach. In this work, a single Kinect sensor and computer have been deployed in five apartments, two of which contain multiple residents, in an independent living facility for older adults. Data collected in the five apartments, along with techniques for generating automated gait measurements from the data, are presented.
本文介绍了使用安装在环境中的深度摄像头(微软Kinect)对7位老年人公寓进行的居家步态测量结果。先前在实验室环境中评估Kinect用于家庭步态评估的工作已经显示了这种方法的潜力。在这项工作中,一个单一的Kinect传感器和电脑被部署在五套公寓中,其中两套公寓有多名居民,在一个独立的老年人生活设施中。介绍了从五套公寓收集的数据,以及从数据中生成自动步态测量的技术。

Towards designing health monitoring interfaces for low socioeconomic status families 面向低社会经济地位家庭的健康监测界面设计
D. U. Khan, K. Siek, S. Ananthanarayan
We conducted a study with eight low socioeconomic status caregivers, the “gatekeepers” to family and community health, to explore their technology perceptions and visualizations that can assist them in managing their families' health. We studied how to visualize the everyday health habits of a population that is at risk for chronic illness. Through semi-structured interviews and prototype design activities, we found that the caregivers wanted to use mobile technology to monitor a subset of their family members for at least one health metric. We inform future work with an analysis of the target population's needs in relation to longitudinal health visualizations with multiple family member data streams.
我们对8位社会经济地位较低的护理人员(家庭和社区健康的“看门人”)进行了一项研究,以探索他们的技术感知和可视化,这些感知和可视化可以帮助他们管理家人的健康。我们研究了如何可视化有慢性疾病风险人群的日常健康习惯。通过半结构化访谈和原型设计活动,我们发现护理人员希望使用移动技术来监测其家庭成员的一个子集,至少有一个健康指标。我们通过分析目标人群与多个家庭成员数据流的纵向健康可视化相关的需求,为未来的工作提供信息。

Fitbit+: A behavior-based intervention system to reduce sedentary behavior Fitbit+:基于行为的干预系统,减少久坐行为
Laura R. Pina, Ernesto Ramirez, W. Griswold
Self-tracking wearable devices are capable of tracking calorie consumption and inferring physical activity physical activity to support self-awareness and healthy behavior. These devices automatically capture human behavior (such as walking) but do not typically make the user aware detected unhealthy behaviors. Furthermore, these devices cannot intervene in the moment to make users aware they are engaging in unhealthy behavior (such as sitting for a long period of time) and persuade them to correct these unhealthy behaviors (e.g., by taking a break to go for a walk). There is an increasing trend for people with low physical activity occupations to sit for long periods of time, yet research suggests that lengthy sitting, independent of overall physical activity level, increases the risk of weight gain and mortality [1]. We aim to decrease the duration of sedentary bouts in the workplace by detecting when people have been inactive for a long time and then prompting them take a short break from their desks. In this poster we present the design of Fitbit+, a system that realizes this strategy by leveraging Fitbit's near real-time, automated step logging to detect sedentary behavior and then prompt users to take short breaks.
自我跟踪可穿戴设备能够跟踪卡路里消耗和推断身体活动,以支持自我意识和健康行为。这些设备会自动捕捉人类行为(比如走路),但通常不会让用户意识到检测到的不健康行为。此外,这些设备不能即时干预,让用户意识到他们正在从事不健康的行为(如长时间坐着),并说服他们纠正这些不健康的行为(如,休息一下去散步)。从事低体力活动职业的人长时间坐着的趋势越来越多,但研究表明,长时间坐着,与整体体力活动水平无关,会增加体重增加和死亡率的风险。我们的目标是减少工作场所久坐不动的持续时间,方法是检测人们什么时候久坐不动,然后促使他们离开办公桌休息一会儿。在这张海报中,我们展示了Fitbit+的设计,该系统通过利用Fitbit近乎实时的自动步数记录来检测久坐行为,然后提示用户进行短暂休息,从而实现了这一策略。

Persuasive strategies for motivating elders to exercise 激励老年人锻炼的说服策略
M. Rodríguez, José R. Roa, A. Morán, S. Nava-Muñoz
Several strategies have been identified for designing effective persuasive technologies that encourage people to adopt healthy lifestyle habits. However, there are no general guidelines for implementing these strategies to motivate elders to exercise, neither they have been evaluated to determine how effective they are for the elderly. To design appropriate persuasive technology prone to be adopted by elders, we are following a user-centered approach. In this paper, we report the design and evaluation of an ambient information system for mobile phones, which supports the following strategies for persuasion: abstraction, historical information and reflection, triggers for exercising, and positive and playful reinforcement.
已经确定了几种策略来设计有效的说服技术,鼓励人们采用健康的生活习惯。然而,目前还没有关于实施这些策略来激励老年人锻炼的一般指导方针,也没有对这些策略进行评估,以确定它们对老年人的有效性。为了设计适合老年人的说服技术,我们遵循以用户为中心的方法。在本文中,我们报告了手机环境信息系统的设计和评估,该系统支持以下说服策略:抽象、历史信息和反思、运动触发以及积极和有趣的强化。

Mobile Health Mashups: Making sense of multiple streams of wellbeing and contextual data for presentation on a mobile device 移动健康mashup:在移动设备上显示多个健康和上下文数据流
Konrad Tollmar, Frank Bentley, Cristobal Viedma
In this paper we present the Mobile Health Mashups system, a mobile service that collects data from a variety of health and wellbeing sensors and presents significant correlations across sensors in a mobile widget as well as on a mobile web application. We found that long-term correlation data provided users with new insights about systematic wellness trends that they could not make using only the time series graphs provided by the sensor manufacturers. We describe the Mobile Health Mashups system with a focus on analyzing and detailing the technical solution, such as: integration of sensors, how to create correlations between various data sets, and the presentation of the statistical data as feeds and graphs. We will also describe the iterative design process that involved a 2-month field trial, the outcome of this trial, and implications for design of mobile data mashup systems.
在本文中,我们介绍了移动健康mashup系统,这是一种从各种健康和福祉传感器收集数据的移动服务,并在移动小部件和移动web应用程序中呈现传感器之间的显著相关性。我们发现,长期相关数据为用户提供了关于系统健康趋势的新见解,这是他们仅使用传感器制造商提供的时间序列图所无法做到的。我们将介绍Mobile Health Mashups系统,重点分析和详细介绍技术解决方案,例如:传感器的集成、如何在各种数据集之间创建相关性,以及将统计数据表示为提要和图表。我们还将描述涉及2个月现场试验的迭代设计过程、试验结果以及对移动数据混搭系统设计的影响。

Pervasive, persuasive health: Some challenges 普遍的、有说服力的健康:一些挑战
Sean A Munson
As we consider the next set of challenges for pervasive health, what are the issues that our current expertise may not sufficiently address? What might we have overlooked that should be on our research agenda as we go forward? In this brief paper, I argue that we would benefit from knowing more about how to design persuasive systems for single use situations (e.g., the decision to get a screening or vaccination) and that people can “graduate” from while maintaining healthy routines and habits they have developed.
当我们考虑全民健康的下一组挑战时,我们目前的专业知识可能无法充分解决哪些问题?在我们前进的过程中,我们可能忽略了哪些应该列入我们研究议程的东西?在这篇简短的文章中,我认为我们将受益于更多地了解如何为单次使用情况(例如,决定接受筛查或接种疫苗)设计有说服力的系统,并且人们可以“毕业”,同时保持他们已经养成的健康的日常生活和习惯。

Towards pervasive physical rehabilitation using Microsoft Kinect 使用微软Kinect实现普遍的身体康复
Chien-Yen Chang, B. Lange, Mi Zhang, S. Koenig, P. Requejo, N. Somboon, A. Sawchuk, A. Rizzo
The use of Virtual Reality technology for developing tools for rehabilitation has attracted significant interest in the physical therapy arena. This paper presents a comparison of motion tracking performance between the low-cost Microsoft Kinect and the high fidelity OptiTrack optical system. Data is collected on six upper limb motor tasks that have been incorporated into a game-based rehabilitation application. The experiment results show that Kinect can achieve competitive motion tracking performance as OptiTrack and provide “pervasive” accessibility that enables patients to take rehabilitation treatment in clinic and home environment.
使用虚拟现实技术开发康复工具已经引起了物理治疗领域的极大兴趣。本文对低成本的微软Kinect和高保真光学系统OptiTrack的运动跟踪性能进行了比较。研究人员收集了六个上肢运动任务的数据,这些数据已被纳入基于游戏的康复应用程序中。实验结果表明,Kinect可以实现与OptiTrack一样具有竞争力的运动跟踪性能,并提供“无处不在”的可访问性,使患者可以在诊所和家庭环境中接受康复治疗。

Estimating nutrition values for internet recipes 估算网上食谱的营养价值
Manuel Müller, Stefanie Mika, Morgan Harvey, David Elsweiler
To utilise the vast recipe databases on the Internet in intelligent nutritional assistance or recommender systems, accurate nutritional data for recipes is needed. Unfortunately, most recipes have no such data or have data of suspect quality. In this demo we present a system that automatically calculates the nutritional value of recipes sourced from the Internet. This is a challenging problem for several reasons, including lack of formulaic structure in ingredient descriptions, ingredient synonymy, brand names, and unspecific quantities being assigned. Our results show that our system can generate nutritional values within a 10% error bound of human assessors for calorie, protein and carbohydrate values. Based on our findings this is smaller than the bound between multiple human assessors.
为了在智能营养辅助或推荐系统中利用互联网上庞大的食谱数据库,需要准确的食谱营养数据。不幸的是,大多数食谱没有这样的数据,或者数据质量可疑。在这个演示中,我们展示了一个系统,它可以自动计算来自互联网的食谱的营养价值。这是一个具有挑战性的问题,有几个原因,包括成分描述缺乏公式化结构,成分同义词,品牌名称,以及分配的数量不明确。我们的研究结果表明,我们的系统可以在人类评估卡路里、蛋白质和碳水化合物价值的10%误差范围内产生营养价值。根据我们的发现,这比多个人类评估者之间的界限要小。

Operationalizing a wireless wearable fall detection sensor for older adults 实现老年人无线可穿戴跌倒检测传感器
Tigest Tamrat, M. Griffin, Sonia Rupcic, S. Kachnowski, Tom Taylor, J. Barfield
Falls are the leading cause of disability and injury-related deaths among older adults, resulting in over 1.6 million annual emergency hospitalizations in the United States. Fall detection devices often rely on dramatized falls when developing algorithms. This study used tri-axial accelerometers worn by older adult research subjects in order to (1) collect false positive data (2) capture potential fall events and (3) evaluate the usability of the device among this target population. Twelve older adults wore activity monitors while participating in structured and unstructured activities. The study collected data on 120 patient days, yielding 492.5 hours of monitored time. Actigraphy data of annotated activities were used to define parameters for refining the algorithm. No falls occurred during the study, but valuable false positive data were collected. The study also obtained information on the usability of the devices and revealed user perspectives on commercializing the final product.
跌倒是导致老年人残疾和受伤相关死亡的主要原因,在美国每年有超过160万人急诊住院。在开发算法时,跌倒检测设备通常依赖于戏剧性的跌倒。本研究使用老年人研究对象佩戴的三轴加速度计,目的是:(1)收集假阳性数据(2)捕捉潜在的跌倒事件(3)评估该设备在目标人群中的可用性。12名老年人在参加有组织和无组织的活动时佩戴活动监测器。该研究收集了120个患者日的数据,产生了492.5小时的监测时间。使用标注活动的活动图数据来定义参数以改进算法。研究期间没有发生跌倒,但收集了有价值的假阳性数据。这项研究还获得了关于设备可用性的资料,并揭示了用户对最终产品商业化的看法。
