Maintaining a certain level of Physical Activity (PA) is important to prevent some chronic pathologies. This is even more important for individuals with severe mental health problems, but they have many barriers that make it very difficult for them to be physically active, including lack of motivation. In this paper, we propose an exergame that aims to help these people integrate PA into their daily lives. This exergame is designed on a smartphone in order to be able to follow the level of activity of the player on a daily basis. It offers game mechanics that allow the player to manage their PA. However, it encourages them to be physically active so that they can progress more easily in the game. The application uses an activity detection algorithm to measure the level of PA. We offer a preliminary study on healthy subjects on a demo version of the game that observes their gaming experience. The results show that the mechanics are globally appreciated and that the game allows each player to manage his PA as he wishes.
保持一定水平的身体活动(PA)对预防一些慢性疾病很重要。这对于有严重精神健康问题的人来说更为重要,但他们有许多障碍,使他们很难进行身体活动,包括缺乏动力。在本文中,我们提出了一个练习游戏,旨在帮助这些人将PA融入他们的日常生活。这款游戏是在智能手机上设计的,以便能够跟踪玩家每天的活动水平。它提供了允许玩家管理他们的PA的游戏机制。然而,它鼓励他们进行身体活动,这样他们就可以更轻松地在游戏中前进。该应用程序使用活动检测算法来测量PA的水平。我们在游戏的演示版本中对健康受试者进行初步研究,观察他们的游戏体验。结果表明,游戏机制得到了全球玩家的认可,并且游戏允许每个玩家按照自己的意愿管理自己的个人助理。

M. Abujelala, Sanika Gupta, F. Makedon
In recent years robots have been replacing human workers in many industries. As robot manufacturing becomes more optimized and cost effective, the use of robots is going to evolve in various fields. Thus, it is essential to prepare workers to operate robots and work collaboratively with them side by side. In this paper, we are proposing a human-robot collaborative task to assess human performance in experimental, industrial setup. The task is designed in both virtual and physical environments.
近年来,机器人在许多行业取代了人类工人。随着机器人制造变得更加优化和具有成本效益,机器人的使用将在各个领域发展。因此,让工人准备好操作机器人并与它们并肩协作是至关重要的。在本文中,我们提出了一个人机协作任务来评估人类在实验,工业设置中的表现。该任务是在虚拟和物理环境中设计的。

Empowering Persons with Deafblindness: Designing an Intelligent Assistive Wearable in the SUITCEYES Project 增强聋哑人的能力:在SUITCEYES项目中设计一种智能辅助穿戴设备
Oliver Korn, R. Holt, Efstratios Kontopoulos, A. Kappers, N. Persson, Nasrine Olson
Deafblindness is a condition that limits communication capabilities primarily to the haptic channel. In the EU-funded project SUITCEYES we design a system which allows haptic and thermal communication via soft interfaces and textiles. Based on user needs and informed by disability studies, we combine elements from smart textiles, sensors, semantic technologies, image processing, face and object recognition, machine learning, affective computing, and gamification. In this work, we present the underlying concepts and the overall design vision of the resulting assistive smart wearable.
聋盲是一种将交流能力主要限制在触觉通道上的疾病。在欧盟资助的项目SUITCEYES中,我们设计了一个系统,该系统允许通过软界面和纺织品进行触觉和热通信。基于用户需求和残疾研究,我们结合了智能纺织品、传感器、语义技术、图像处理、面部和物体识别、机器学习、情感计算和游戏化等元素。在这项工作中,我们提出了潜在的概念和由此产生的辅助智能可穿戴设备的整体设计愿景。

Exploring epistaxis as an adverse effect of anti-thrombotic drugs and outdoor temperature 探讨抗栓药物与室外温度对鼻出血的不良影响
J. Hollmén, L. Asker, Isak Karlsson, P. Papapetrou, Henrik Boström, B. N. Wikner, Inger Öhman
Electronic health records contain a wealth of epidemiological information about diseases at the population level. Using a database of medical diagnoses and drug prescriptions in electronic health records, we investigate the correlation between outdoor temperature and the incidence of epistaxis over time for two groups of patients. One group consists of patients that had been diagnosed with epistaxis and also been prescribed at least one of the three anti-thrombotic agents: Warfarin, Apixaban, or Rivaroxaban. The other group consists of patients that had been diagnosed with epistaxis and not been prescribed any of the three anti-thrombotic drugs. We find a strong negative correlation between the incidence of epistaxis and outdoor temperature for the group that had not been prescribed any of the three anti-thrombotic drugs, while there is a weaker correlation between incidence of epistaxis and outdoor temperature for the other group. It is, however, clear that both groups are affected in a similar way, such that the incidence of epistaxis increases with colder temperatures.
电子健康记录包含大量关于人口一级疾病的流行病学信息。利用电子健康记录中的医疗诊断和药物处方数据库,我们研究了室外温度与两组患者鼻衄发生率之间的相关性。一组由诊断为鼻出血的患者组成,并且至少服用了三种抗血栓药物中的一种:华法林、阿哌沙班或利伐沙班。另一组由被诊断为鼻出血且未服用任何三种抗血栓药物的患者组成。我们发现,对于未使用三种抗血栓药物的组,鼻出血发生率与室外温度之间存在很强的负相关,而对于另一组,鼻出血发生率与室外温度之间的相关性较弱。然而,很明显,这两组人受到的影响是相似的,即鼻出血的发生率随着温度的降低而增加。

M. Haseeb, Maria Kyrarini, Shuo Jiang, Danijela Ristić-Durrant, A. Gräser
Development of assistive robotics to enable people with disabilities to work is a challenging topic. Hands-free interfaces can support a person with severe motor impairments to control robotic manipulators. The paper focuses on developing a head gesture interface, which enables the end-user to control a dual-arm industrial robot. A motion sensor is located on the head of the end-user. Support vector machine is used to recognize the head gestures and an intuitive Graphical User Interface is developed to help the user to navigate through different control modes. To evaluate the proposed framework, an industrial pick and place task was performed.

Enabling Early Gesture Recognition by Motion Augmentation 通过运动增强实现早期手势识别
R. Agrawal, Ajjen Joshi, Margrit Betke
In real-time gesture recognition algorithms, accurately classifying gestures early, when they are only partially observed, can be advantageous as it minimizes latency and improves user experience. This work investigates a novel approach for improving the results of an early gesture classification model. The method involves augmenting the input sequence of human poses of a partially observed gesture with a series of poses predicted by an auxiliary recurrent neural network sequence-to-sequence motion prediction model before being fed into a random forest gesture classifier. By concatenating the partially observed ground truth sequence with the forecasted motion sequence, we are able to significantly improve early gesture recognition accuracy. When forecasting 25 future frames of a partially observed input gesture sequence of 50 frames, recognition accuracy improves from 45% to 87% on average when evaluated on the MSRC-12 gesture dataset.
在实时手势识别算法中,当手势仅被部分观察到时,尽早对手势进行准确分类是有利的,因为它可以最大限度地减少延迟并改善用户体验。本文研究了一种改进早期手势分类模型结果的新方法。该方法包括在输入到随机森林手势分类器之前,用辅助递归神经网络序列到序列运动预测模型预测的一系列姿势来增加部分观察到的手势的人体姿势输入序列。通过将部分观察到的地面真实序列与预测的运动序列串联起来,我们能够显著提高早期手势识别的准确性。当预测部分观察到的50帧输入手势序列的25个未来帧时,在MSRC-12手势数据集上评估的识别准确率平均从45%提高到87%。

What makes people accept or reject companion robots?: A research agenda 是什么让人们接受或拒绝伴侣机器人?:研究议程
A. Weiss, Glenda Hannibal
Social companion robots are intentionally developed and designed to support humans in useful tasks and to use social cues to establish a relationship to the user. However, so far no social companion robots existed outside of research labs to perform long-term studies "in the wild", exploring how this relationship actually evolves over time. In this paper we present the research agenda for such a study using the soon commercially available BUDDY robot from Blue Frog Robotics. We chose a sociological ethnographic approach with eight households, methodologically mainly focusing on qualitative data gathered through a series of household visits. For data analysis we aim at extending the Domestic Robot Ecology (DRE), which was originally developed based on ethnographic studies with vacuum cleaning robots, and for data interpretation we base our work on a newly proposed sociological framework, we call everyday-life centered approach (ELCA).
社交伴侣机器人是有意开发和设计的,用于支持人类完成有用的任务,并使用社交线索与用户建立关系。然而,到目前为止,在研究实验室之外还没有社交伴侣机器人来进行“野外”的长期研究,探索这种关系是如何随着时间的推移而演变的。在本文中,我们使用Blue Frog Robotics即将上市的BUDDY机器人提出了这样一项研究的研究议程。我们选择了社会学人种志方法,研究了8个家庭,方法上主要关注通过一系列家访收集的定性数据。对于数据分析,我们的目标是扩展家用机器人生态学(DRE),该生态学最初是基于真空清洁机器人的人种学研究开发的,对于数据解释,我们基于新提出的社会学框架,我们称之为以日常生活为中心的方法(ELCA)。

Experiences with an Assistive System for Manual Assembly 有使用人工装配辅助系统的经验
Jean D. Hallewell Haslwanter, Boban Blazevski
Small lot sizes in modern manufacturing present new challenges for people doing complex manual assembly tasks, as every item produced may be different. Assistance systems can support people assembling different variants and reduce stress, while also reducing the number of errors. This paper reports on a qualitative study which used interviews and thematic analysis to study the experiences of one company with an innovative system designed to support workers assembling small lot sizes. The system provides photographs and instructions to people doing manual assembly of engines. The study was done after an extended pilot, and before the next release that will be rolled out to the main assembly lines. The goal of the study was to understand the needs and problems in practice in order to support people developing the next generation of these types of systems. The results highlight the importance of integrating these systems with existing systems, but also the way in which the way the information is delivered depends on the primary goal, e.g. supporting different variants, new workers or quality.
现代制造业的小批量生产给从事复杂手工装配任务的人带来了新的挑战,因为生产的每件产品都可能不同。辅助系统可以帮助人们组装不同的变体,减轻压力,同时也减少了错误的数量。本文报告了一项定性研究,该研究采用访谈和专题分析来研究一家公司的经验,该公司采用创新系统来支持工人组装小批量。该系统为手工组装发动机的人员提供照片和说明。这项研究是在一个扩展的试点之后,在下一个版本将被推出到主要装配线之前完成的。这项研究的目的是了解实践中的需求和问题,以便支持人们开发下一代这些类型的系统。结果强调了将这些系统与现有系统集成的重要性,但也强调了信息传递的方式取决于主要目标,例如支持不同的变体、新工人或质量。

Temporal Modification of Apriori to find Seasonal Variations between Symptoms and Diagnoses 先验时间修正发现症状与诊断之间的季节变化
Aashara Shrestha, L. Fegaras, D. Zikos
Medical data can be mined for patterns, which may be used to predict candidate diagnoses according to symptoms and other parameters of care. Our hypothesis is that the admission (initial) patient assessment, when combined with seasonal information can provide more accurate insights for the patient diagnosis. For instance, when cough is the symptom, the probability for flu could be higher during the winter (flu season). We hereby present a method to estimate the temporal variation of the probability for a diagnosis, when the initial patient assessment is known. In order to develop the model, we utilized a large synthetic medical claims dataset from the Centers for Medicare and Medicaid Services. We used the Apriori algorithm to calculate the support and confidence for each 'admission_diagnosis~final_diagnosis' itemset. For each itemset, 52 rules were generated, one for each week of a calendar year. The Apriori output was filtered so that only itemsets with the 'admission diagnosis' on the Left Hand Side(LHS) are extracted. We furthermore smoothened, using the Exponentially Weighted Moving Average (EWMA) algorithm, and then visualized the week-by-week variability of confidence, for any 'admission_diagnosis~fmal_diagnosis' pair of interest. With our approach, researchers can observe seasonal variations of the diagnosis element, and further study these variations for causal knowledge discovery.
可以对医疗数据进行模式挖掘,这些模式可用于根据症状和其他护理参数预测候选诊断。我们的假设是,入院(初始)患者评估,当与季节信息相结合时,可以为患者诊断提供更准确的见解。例如,以咳嗽为症状时,在冬季(流感季节)患流感的可能性会更高。我们在此提出一种方法来估计概率的时间变化的诊断,当初步的病人评估是已知的。为了开发该模型,我们利用了来自医疗保险和医疗补助服务中心的大型合成医疗索赔数据集。我们使用Apriori算法计算每个“admission_diagnosis~final_diagnosis”项集的支持度和置信度。对于每个项目集,生成了52条规则,每个规则对应日历年的一周。对Apriori输出进行了过滤,以便只提取左侧(LHS)具有“入院诊断”的项目集。我们进一步使用指数加权移动平均(EWMA)算法进行平滑,然后对任何感兴趣的“admission_diagnosis~fmal_diagnosis”对的置信度逐周变化进行可视化。通过我们的方法,研究人员可以观察到诊断元素的季节变化,并进一步研究这些变化以发现因果知识。

Video Based Fall Detection using Features of Motion, Shape and Histogram 基于运动、形状和直方图特征的视频跌倒检测
Suad Albawendi, Ahmad Lotfi, Heather Powell, Kofi Appiah
Falls are one of the greatest risks for the older adults living alone at home. This paper presents a novel visual-based fall detection approach to support independent living for older adults. The proposed approach employs three unique features; motion information, human shape variation and projection histogram to detect a fall. Motion information of a segmented silhouette, which when extracted can provide a useful cue for classifying different behaviours. Also, the projection histogram and variation in human shape can be used to describe human body postures and subsequently fall events. The proposed approach presented here extracts motion information, using best-fit approximated ellipse around the human body and in addition projection histogram features to further improve the accuracy of fall detection. Experimental results are presented and show high fall detection rate of 99.81% with partially occluded video data.
对于独居的老年人来说,跌倒是最大的风险之一。本文提出了一种新的基于视觉的跌倒检测方法,以支持老年人的独立生活。该方法采用了三个独特的特征;运动信息,人体形状变化和投影直方图检测跌倒。分割后的轮廓运动信息可以为不同的行为分类提供有用的线索。此外,投影直方图和人体形状的变化可以用来描述人体姿势和随后的跌倒事件。本文提出的方法提取运动信息,利用人体周围最适合的近似椭圆和投影直方图特征,进一步提高跌倒检测的准确性。实验结果表明,对于部分遮挡的视频数据,跌落检测率高达99.81%。

This paper presents a novel visual-based fall detection approach to support independent living for older adults. The proposed approach employs three unique features; motion information, human shape variation and projection histogram to detect a fall. Motion information of a segmented silhouette, which when extracted can provide a useful cue for classifying different behaviours. Also, the projection histogram and variation in human shape can be used to describe human body postures and subsequently fall events.
