A vocal modulation model with application to predicting depression severity 声音调节模型在抑郁症严重程度预测中的应用
Rachelle L. Horwitz-Martin, T. Quatieri, Elizabeth Godoy, J. Williamson
Speech provides a potential simple and noninvasive “on-body” means to identify and monitor neurological diseases. Here we develop a model for a class of vocal biomarkers exploiting modulations in speech, focusing on Major Depressive Disorder (MDD) as an application area. Two model components contribute to the envelope of the speech waveform: amplitude modulation (AM) from respiratory muscles, and AM from interaction between vocal tract resonances (formants) and frequency modulation in vocal fold harmonics. Based on the model framework, we test three methods to extract envelopes capturing these modulations of the third formant for synthesized sustained vowels. Using subsequent modulation features derived from the model, we predict MDD severity scores with a Gaussian Mixture Model. Performing global optimization over classifier parameters and number of principal components, we evaluate performance of the features by examining the root-mean-squared error (RMSE), mean absolute error (MAE), and Spearman correlation between the actual and predicted MDD scores. We achieved RMSE and MAE values 10.32 and 8.46, respectively (Spearman correlation=0.487, p<;0.001), relative to a baseline RMSE of 11.86 and MAE of 10.05, obtained by predicting the mean MDD severity score. Ultimately, our model provides a framework for detecting and monitoring vocal modulations that could also be applied to other neurological diseases.
语言为识别和监测神经系统疾病提供了一种潜在的简单且无创的“身体”手段。在这里,我们开发了一类利用语音调节的声音生物标志物的模型,重点关注重度抑郁症(MDD)作为一个应用领域。语音波形的包络由两个模型组成:呼吸肌的调幅(AM)和声道共振(共振峰)与声带谐波的调频相互作用的调幅。基于模型框架,我们测试了三种方法来提取包络,这些包络捕获了合成持续元音的第三个构成体的这些调制。利用模型衍生的后续调制特征,我们用高斯混合模型预测MDD严重程度评分。通过对分类器参数和主成分数量进行全局优化,我们通过检查实际和预测MDD分数之间的均方根误差(RMSE)、平均绝对误差(MAE)和Spearman相关性来评估特征的性能。我们获得的RMSE和MAE值分别为10.32和8.46 (Spearman相关=0.487,p< 0.001),相对于通过预测平均重度抑郁症评分获得的基线RMSE为11.86和MAE为10.05。最终,我们的模型为检测和监测声音调节提供了一个框架,也可以应用于其他神经系统疾病。

Gait tracker shoe for accurate step-by-step determination of gait parameters 步态跟踪鞋,准确一步一步确定步态参数
Yan Zhuang, Jiaqi Gong, D. Kerrigan, B. Bennett, J. Lach, S. Russell
Step-by-step determination of gait parameters provides insight into the variability of specific gait patterns associated with frequent injuries in the lower extremities of adolescents and with geriatric syndromes of the elderly. Numerous methods have been developed for the step-by-step estimation of gait parameters, but most are expensive, obtrusive, inconvenient, and/or inaccurate. In this paper, we developed an innovative shoe, called the “Gait Tracker”, with a low power inertial measurement unit (IMU) embedded in a 3D printed sole that provides unobtrusive, continuous, and accurate step-by-step measurement of gait parameters for individual use. This shoe enables out-of-lab gait monitoring in a wide range of activities and over an extended period of time. Experimental results from controlled studies demonstrated that the Gait Tracker can recognize various gait events and provide better accuracy in stride length measurement compared to previous systems and methods.
一步一步的确定步态参数提供了洞察特定的步态模式的可变性与频繁损伤的下肢青少年和老年综合征的老年人。已经开发了许多方法来逐步估计步态参数,但大多数是昂贵的,突兀的,不方便的,和/或不准确的。在本文中,我们开发了一种名为“步态跟踪器”的创新鞋,在3D打印鞋底中嵌入了低功耗惯性测量单元(IMU),可为个人使用提供不引人注目,连续且准确的步态参数逐步测量。这款鞋可以在实验室外进行大范围的活动和长时间的步态监测。对照研究的实验结果表明,步态跟踪器可以识别各种步态事件,并且与以前的系统和方法相比,可以提供更好的步长测量精度。

Towards a comprehensive power consumption model for wireless sensor nodes 面向无线传感器节点的综合功耗模型
Marc Hesse, Michael Adams, Timm Hormann, U. Rückert
Energy efficiency is the most outstanding design criterion for wireless sensor nodes and especially wireless body sensors. Because a detailed measurement of the system's power consumption is not possible during the design process and often too complex for already manufactured devices, the power consumption has to be estimated. This leads to the need for a comprehensive and modular model for the power consumption of WSNs, which is proposed in this work. Due to the modular structure of the model the user is able to get a first estimate in an early stage of the design process (e.g. choose components) and to get a more accurate estimation later in the design process by lowering the abstraction level. This tackles the demanding trade-off between accuracy and usability in modeling.
能效是无线传感器节点尤其是无线身体传感器最重要的设计准则。由于在设计过程中不可能对系统的功耗进行详细测量,并且对于已经制造的设备来说通常过于复杂,因此必须对功耗进行估计。这导致需要一个全面的模块化的无线传感器网络功耗模型,这是在这项工作中提出的。由于模型的模块化结构,用户能够在设计过程的早期阶段(例如选择组件)获得第一个估计,并在设计过程的后期通过降低抽象级别获得更准确的估计。这解决了建模中准确性和可用性之间的权衡。

Priyanka Rathod, K. George, Nikhil Shinde
In the past several years, significant research has been conducted in the area of real-time emotion recognition. Emotion recognition has several potential applications in education, medicine, assistive technologies and human-machine interaction. A real-time emotion detection device that utilizes heart rate and skin conductance sensors is presented in this paper. OpenCV, open face libraries and insight SDK is utilized to detect emotions from facial expressions. The performance of the device is evaluated using experiments which had subjects watch audiovisual clips in various emotional categories. Also, in order to verify the feasibility of utilizing bio-signals to predict emotions, facial expressions captured from a webcam are processed in parallel to compare and contrast.

Profiling, modeling, and predicting energy harvesting for self-powered body sensor platforms 自供电身体传感器平台的分析、建模和预测能量收集
Dawei Fan, Luis Javier Lopez Ruiz, Jiaqi Gong, J. Lach
Energy harvesting offers the promise of mobile sensor systems capable of quasi-perpetual operation, but the discontinuous and dynamic characteristics of harvesting in real-world scenarios - necessary for the design and operation of self-powered systems - are not yet well understood. The paper presents a hardware platform for providing a comprehensive real-world evaluation of two energy harvesting modalities common to body sensor networks: indoor light and thermoelectric. Day-long multi-modal energy harvesting profiles were generated, which were then used to develop a mathematical model to predict real time energy harvesting values from the sampled environmental and human behavioral parameters. Experimental results demonstrate that the model is effective in calculating and predicting harvested energy in real time, and a multi-source scheme for continuous operation of self-powered sensors is demonstrated.

On single sensor-based inertial navigation 基于单传感器的惯性导航
Nicolò Strozzi, Federico Parisi, G. Ferrari
In this paper, we compare two novel algorithms for pedestrian navigation based on signals collected by a single wearable Magnetic, Angular Rate, and Gravity (MARG) sensor. The two navigation algorithms, denoted as Enhanced Pedestrian Dead Reckoning (EPDR) and De-Drifted Propagation (DDP), require the placement of the MARG sensor on the foot or on the chest of the test subject, respectively. Different methods for gait characterization are compared, evaluating navigation dynamics by using data collected through an extensive experimental campaign. The main goal of this research is to investigate the peculiarities of different inertial navigation algorithms, in order to highlight the impact of the sensor's placement, together with inertial sensor issues. Considering a closed path (i.e., ending at the starting point), the relative distance error between the starting point and the final estimated position is about 2% of the total travelled distance for both DDP and EPDR navigation algorithms. On the other hand, the error between the initial heading angle and the final estimated one is approximately 10° for EPDR and 7° for DDP, respectively.
在本文中,我们比较了两种基于单个可穿戴磁、角速率和重力(MARG)传感器收集的信号的行人导航新算法。这两种导航算法分别被称为增强行人航迹推算(Enhanced Pedestrian Dead Reckoning, EPDR)和去漂移传播(de - drift Propagation, DDP),它们要求将MARG传感器分别放置在受试者的脚上或胸部。比较了不同的步态表征方法,通过广泛的实验活动收集的数据来评估导航动力学。本研究的主要目的是研究不同惯性导航算法的特点,以突出传感器放置的影响,以及惯性传感器问题。考虑闭合路径(即在起始点结束),对于DDP和EPDR导航算法,起始点与最终估计位置之间的相对距离误差约为总行进距离的2%。另一方面,EPDR和DDP的初始航向角与最终估计航向角的误差分别约为10°和7°。

Mathieu Simonnet, Bernard Gourvennec
In the present study we focused on heart rate sensors and compared the acceptability and usability of the various devices candidates to feed the PRECIOUS (PREventive Care Infrastructure based On Ubiquitous Sensing) system. More precisely, smart-watch, chest-belt and 2-points-electrodes have been tested by users during 24 hours. Each device test lead to consult lifestyle reports about stress, sleep and physical activity. During this experimentation 11 participants completed different acceptability questionnaires. The first results interpretation revealed which sensor is the most acceptable and gave insight into how data reliability of the different devices influenced their respective acceptability in the daily life.

Diet eyeglasses: Recognising food chewing using EMG and smart eyeglasses 减肥眼镜:使用肌电图和智能眼镜识别食物咀嚼
Rui Zhang, Severin Bernhart, O. Amft
We utilise smart eyeglasses for dietary monitoring, in particular to sense food chewing. Our approach is based on a 3D-printed regular eyeglasses design that could accommodate processing electronics and Electromyography (EMG) electrodes. Electrode positioning was analysed and an optimal electrode placement at the temples was identified. We further compared gel and dry fabric electrodes. For the subsequent analysis, fabric electrodes were attached to the eyeglasses frame. The eyeglasses were used in a data recording study with eight participants eating different foods. Two chewing cycle detection methods and two food classification algorithms were compared. Detection rates for individual chewing cycles reached a precision and recall of 80%. For five foods, classification accuracy for individual chewing cycles varied between 43% and 71%. Majority voting across intake sequences improved accuracy, ranging between 63% and 84%. We concluded that EMG-based chewing analysis using smart eyeglasses can contribute essential chewing structure information to dietary monitoring systems, while the eyeglasses remain inconspicuous and thus could be continuously used.
我们利用智能眼镜进行饮食监测,特别是感知食物咀嚼。我们的方法是基于3d打印的普通眼镜设计,可以容纳处理电子和肌电(EMG)电极。对电极定位进行了分析,确定了太阳穴的最佳电极位置。我们进一步比较了凝胶电极和干织物电极。为了进行后续分析,织物电极被附着在眼镜框架上。该眼镜被用于一项数据记录研究,8名参与者吃不同的食物。比较了两种咀嚼周期检测方法和两种食物分类算法。单个咀嚼循环的检测准确率和召回率达到80%。对于五种食物,单个咀嚼周期的分类准确率在43%到71%之间变化。在摄入序列中进行多数投票提高了准确率,范围在63%到84%之间。我们得出结论,使用智能眼镜进行基于肌电图的咀嚼分析可以为饮食监测系统提供必要的咀嚼结构信息,同时眼镜不显眼,因此可以连续使用。

A novel approach to detect localized muscle fatigue during isometric exercises 在等长运动中检测局部肌肉疲劳的新方法
P. Bhat, Ajay K. Gupta
The purpose of this study is to develop a localized muscle fatigue detection system to assist patients during isometric exercise. A mobile device is fastened to the forehand of the subject to receive electromyography (EMG) signals sent wirelessly from BITalino board. Our proposed system then uses surface electromyography (sEMG) technique to capture electromyography (EMG) signals that are processed in time-frequency domain using short-term Fourier transform. The vibration speed received through accelerometer sensor caused by the muscle fatigue at biceps brachii of a subject is calculated in parallel. The downward shift in Median Frequency and increase in vibration speed are taken as parameters to determine the localized muscle fatigue. Results indicate that localized muscle fatigue can be observed effectively with these two parameters combined together.
本研究的目的是开发局部肌肉疲劳检测系统,以协助患者进行等长运动。一个移动设备被固定在受试者的正手,以接收从BITalino板无线发送的肌电(EMG)信号。然后,我们提出的系统使用表面肌电图(sEMG)技术捕获肌电图(EMG)信号,这些信号使用短期傅里叶变换在时频域进行处理。平行计算受试者肱二头肌肌肉疲劳引起的加速度传感器接收到的振动速度。以中位数频率的下移和振动速度的增加作为判断局部肌肉疲劳的参数。结果表明,这两个参数联合使用可以有效地观察局部肌肉疲劳。

J. A. Khan, Haroon Ali Akbar, Usama Pervaiz, Osman Hassan
This paper presents a low cost, low power and wireless wearable solution for real-time analysis and monitoring of cardiac activity co-related with physical activity. Utilizing an analogue filter chain for signal conditioning, the device performs continuous measurement of the Electrocardiogram. The wearable also includes an accelerometer enabling it to detect the current physical activity along with body orientation. The device communicates wirelessly, using Bluetooth Smart /Bluetooth Low Energy, with a smart phone, where a complete analysis can be performed on the received data, and decisions about the current health conditions can be made.
