Erratum: Tactile Vibrating Toolkit and Driving Simulation Platform for Driving-Related Research

根据《2016年全球卫生估计》公布的数据，交通伤害是全球死亡的第八大原因，导致全球140万人死亡。2018年，39.2%的交通事故是与运输中的机动车相撞，7.2%是后端碰撞。提高车辆和道路安全的解决方案是开发先进的驾驶辅助系统 （ADAS），以警告有潜在危险的驾驶员。数据表明，ADAS可以大大降低后端碰撞的速度，而且配备自动制动系统2更有效。此外，随着自动驾驶汽车的发展，控制车辆需要较少的人为参与，因此，当自动驾驶车辆无法自我调节时，必须实施接管请求 （TOR） 警告系统。ADAS 和 TOR 报警系统的设计现在是驾驶员在几秒钟内避免即将发生的事故的重要技术。示例实验使用振动工具包和驾驶模拟平台，以调查当振动警告系统被用作潜在的 ADAS 和 TOR 警告系统时，哪个位置将产生最佳结果。
按感性通道分类，通常有三种类型的警告方式，即视觉、听觉和触觉。每个警告方式都有其自身的优点和局限性。当视觉警告系统在使用时，司机可能会遭受视觉超载3，由于漫不经心的失明4，5损害驾驶性能。虽然听觉警告系统不会影响驾驶员的视觉领域，但其有效性在很大程度上取决于周围环境，如背景音乐和驾驶环境中的其他噪音。因此，包含其他外部听觉信息或显著噪音的情况可能导致漫不经心的耳聋8、9，从而降低听觉警告系统的有效性。相比之下，触觉警告系统与驾驶员的视觉或听觉处理不相竞争。通过向驾驶员发送振动警告，触觉警告系统克服了视觉和听觉警告系统的局限性。
先前的研究表明，触觉警告可以通过缩短制动响应时间使驾驶员受益。还发现，在某些情况下，触觉警告系统比视觉10、11和听觉12、13、14预警系统产生更有效的结果。然而，有限的研究侧重于研究放置触觉警告装置的最佳位置。根据感官皮层假说15和感官距离假说16，范例研究选择手指、手腕和寺庙区域作为放置触觉警告装置的实验地点。通过引入的协议，振动警告的频率和传递时间，以及振动工具包振动之间的间隔，可以配置以适应实验要求。这个振动工具包包括主芯片、电压调节器芯片、多路复用器、晶体管-晶体管-逻辑（TTL）适配器USB、金属-氧化物-半导体场效应晶体管（MOSFET）和蓝牙模块。振动模块的数量也会根据研究人员的需求而变化，最多有四个模块同时振动。在驾驶相关实验中实施振动工具包时，可以通过修订驾驶模拟代码来配置以适应实验设置并与驾驶性能数据同步。
而对于研究人员来说，由于涉及的风险和成本，在虚拟平台上进行驾驶实验比在现实世界中更可行。例如，收集绩效指标可能很困难，在现实世界中进行实验时很难控制所涉及的环境因素。因此，近年来，许多研究都使用在个人电脑上运行的固定基础驾驶模拟器作为进行公路驾驶研究的替代方案。在驾驶研究界学习、开发和研究超过 11 年之后，我们建立了一个驾驶模拟平台，它包含一个开源驾驶模拟软件和硬件套件，包括方向盘和变速箱、三个踏板、三个安装投影仪和三个投影仪屏幕。由于驾驶模拟软件仅支持单个屏幕，所呈现的协议仅使用中央投影仪和投影仪屏幕进行实验。
使用呈现的驾驶模拟平台有两个主要优点。此平台的一个优点是它使用开源软件。使用用户友好的开源平台，研究人员可以定制模拟和振动工具包，以满足他们独特的研究需求，无需任何代码开发的简单软件配置。通过修订代码，研究人员可以创建驾驶模拟，提供相对保真到现实与汽车类型，道路类型，方向盘的阻力，横向和纵向风湍流，时间和制动事件应用程序接口 （ABI） 外部软件同步，并实现行为范式，如汽车跟随任务和 N-Back 任务。虽然在驾驶模拟器中进行与驾驶相关的研究不能完全复制现实世界中的驾驶，但通过驾驶模拟器收集的数据是合理的，并已被研究人员广泛采用。
建议的驾驶模拟器的另一个优点是成本低。如前所述，引入的驾驶模拟软件是一种开源软件，可供用户免费使用。此外，与典型的高保真商用驾驶模拟器相比，此协议中整个硬件设置的总成本较低。图 1 a 和 b 显示了两个驾驶模拟器的完整设置，费用从 3000 美元到 30000 美元不等。相比之下，典型的高保真商用驾驶模拟器（固定基座）通常成本在 10，000 到 100，000 美元之间。这种驾驶模拟器价格实惠，不仅供学术研究之用，而且可用于驾驶课程19和驾驶相关技术20、21的演示。
<img alt="Figure 1" class="xfigimg" src="/files/ftp_upload/61408/61408fig1v2.jpg"> 图1:驾驶模拟器的图像。两个驾驶模拟器包括方向盘和变速箱、三个踏板和一辆车。（a） 使用分辨率为 3840 × 2160 的 80 英寸 LCD 屏幕的 3000 美元驾驶模拟器设置。（b） 一个价值 30000 美元的驾驶模拟器设置，使用三台安装投影仪和三台投影仪屏幕，每个屏幕的尺寸为 223 x 126 厘米。投影屏幕放置在离地面60厘米和22厘米远的车辆前部。当前实验只使用了中央投影仪和投影仪屏幕。 <a href="https://jove.unicartagenaproxy.elogim.com/files/ftp_upload/61408/61408fig1v2large.jpg" target="_blank">请点击这里查看此数字的较大版本。</a>
驾驶模拟软件和振动工具包在建议的方法已经用于以前的研究，我们的研究人员22，23，24，25，26，27，28，29。这种按照ISO标准30自行开发的振动工具包可以通过调整振动频率和强度应用于不同的字段31、32。需要注意的是，振动工具包的新版本已经开发并引入以下协议中。较新的版本没有使用可调电压适配器调整振动频率，而是配备了五种不同的振动频率，并且可以使用补充编码文件 1中提供的代码进行更轻松的调整。此外，所展示的驾驶模拟器为研究人员提供了一种安全、廉价和有效的方法来研究各种与驾驶相关的研究。因此，此协议适用于预算有限且极需定制实验驾驶环境的研究实验室。

tactile vibrating toolkit and driving simulation platform for driving-related research

碰撞警告系统在防止驾驶分心和昏昏欲睡驾驶方面发挥着关键作用。先前的研究已经证明了触觉警告在减少驾驶员制动响应时间方面的优势。同时，在部分自动驾驶车辆的接管请求 （TOR） 中，触觉警告已被证明是有效的。
如何优化触觉警告的性能是该领域的一个持续热门研究课题。因此，引入了低成本驾驶模拟软件和方法，以吸引更多的研究人员参与调查。提交的协议分为五个部分:1）参与者，2）驾驶模拟软件配置，3）驾驶模拟器准备，4）振动工具包配置和准备，5）进行实验。
在范例研究中，参与者佩戴触觉振动工具包，使用定制的驾驶模拟软件执行既定的汽车跟踪任务。前车间歇性刹车，每当前车刹车时都会发出振动警告。参与者被指示对前车的突然刹车做出尽可能快的反应。用于数据分析的模拟软件记录了驾驶动态，如制动响应时间和制动响应速率。
所提交的协议提供了对触觉警告在不同身体位置的有效性的探索的见解。除了在示例实验中演示的汽车跟随任务外，此协议还提供了选项，通过在无需任何代码开发的情况下进行简单的软件配置，将其他范式应用于驾驶模拟研究。然而，重要的是要注意，由于其负担得起的价格，这里推出的驾驶模拟软件和硬件可能无法与其他高保真商业驾驶模拟器充分竞争。然而，该协议可以作为一个负担得起的和用户友好的替代一般高保真商业驾驶模拟器。

本文报道的这一范例研究使用驾驶模拟器和振动工具包执行了汽车跟踪任务，该工具包此前也发表在学术期刊22上。值得注意的是，振动工具包的旧版本是在进行例证研究时使用的，而上述协议中引入了振动工具包的新版本。这项研究是一个主题内的设计实验，振动警告位置是唯一的因素:手指，手腕，寺庙警告条件，和驾驶只条件作为控制。每个条件包括13个随机制动事件，导?...

Quantitative Assessment of Cortical Auditory-tactile Processing in Children with Disabilities

Objective and easy measurement of sensory processing is extremely difficult in nonverbal or vulnerable pediatric patients. We developed a new methodology to quantitatively assess children&#39;s cortical processing of light touch, speech sounds and the multisensory processing of the 2 stimuli, without requiring active subject participation or causing children discomfort. To accomplish this we developed a dual channel, time and strength calibrated air puff stimulator that allows both tactile stimulation and sham control. We combined this with the use of event-related potential methodology to allow for high temporal resolution of signals from the primary and secondary somatosensory cortices as well as higher order processing. This methodology also allowed us to measure a multisensory response to auditory-tactile stimulation.

Measurement of Vibration Detection Threshold and Tactile Spatial Acuity in Human Subjects

Tests that allow the precise determination of psychophysical thresholds for vibration and grating orientation provide valuable information about mechanosensory function that are relevant for clinical diagnosis as well as for basic research. Here, we describe two psychophysical tests designed to determine the vibration detection threshold (automated system) and tactile spatial acuity (handheld device). Both procedures implement a two-interval forced-choice and a transformed-rule up and down experimental paradigm. These tests have been used to obtain mechanosensory profiles for individuals from distinct human cohorts such as twins or people with sensorineural deafness.

Here, we present protocols to determine vibration detection thresholds and tactile acuity using psychophysical methods in man.

Testing Tactile Masking between the Forearms

Masking, in which one stimulus affects the detection of another, is a classic technique that has been used in visual, auditory, and tactile research, usually using stimuli that are close together to reveal local interactions. Masking effects have also been demonstrated in which a tactile stimulus alters the perception of a touch at a distant location. Such effects can provide insight into how components of the body's representations in the brain may be linked. Occasional reports have indicated that touches on one hand or forearm can affect tactile sensitivity at corresponding contralateral locations. To explore the matching of corresponding points across the body, we can measure the spatial tuning and effect of posture on contralateral masking. Careful controls are required to rule out direct effects of the remote stimulus, for example by mechanical transmission, and also attention effects in which thresholds may be altered by the participant's attention being drawn away from the stimulus of interest. The use of this technique is beneficial as a behavioural measure for exploring which parts of the body are functionally connected and whether the two sides of the body interact in a somatotopic representation. This manuscript describes a behavioural protocol that can be used for studying contralateral tactile masking.

Here we explore contralateral tactile masking between the forearms in which tactile detection thresholds are modulated by vibration applied to a remote site. The details of which remote sites have an effect can tell us about how the body is represented in the brain.

A Microphysiologic Platform for Human Fat: Sandwiched White Adipose Tissue

White adipose tissue (WAT) plays a crucial role in regulating weight and everyday health. Still, there are significant limitations to available primary culture models, all of which have failed to faithfully recapitulate the adipose microenvironment or extend WAT viability beyond two weeks. The lack of a reliable primary culture model severely impedes research in WAT metabolism and drug development. To this end we have utilized NIH's standards of a microphysiologic system to develop a novel platform for WAT primary culture called 'SWAT' (sandwiched white adipose tissue). We overcome the natural buoyancy of adipocytes by sandwiching minced WAT clusters between sheets of adipose-derived stromal cells. In this construct, WAT samples are viable over eight weeks in culture. SWAT maintains the intact ECM, cell-to-cell contacts, and physical pressures of in vivo WAT conditions; additionally, SWAT maintains a robust transcriptional profile, sensitivity to exogenous chemical signaling, and whole tissue function. SWAT represents a simple, reproducible, and effective method of primary adipose culture. Potentially, it is a broadly applicable platform for research in WAT physiology, pathophysiology, metabolism, and pharmaceutical development.

White adipose tissue (WAT) has critical deficiencies in its current primary culture models, hindering pharmacological development and metabolic studies. Here, we present a protocol to produce an adipose microphysiological system by sandwiching WAT between sheets of stromal cells. This construct provides a stable and adaptable platform for primary WAT culture.

A Novel Single Animal Motor Function Tracking System Using Simple, Readily Available Software

We have recently demonstrated that implanting intracortical microelectrodes in the motor corteces of rats&#160;results in immediate and lasting motor deficits. Motor impairments were manually quantified through an open field grid test to measure the gross motor function and through a ladder test to measure the fine motor function. Here, we discuss a technique for the automated quantification of the video-recorded tests using our custom Capadona Behavioral Video Analysis System: Grid and Ladder Test, or BVAS. Leveraging simple and readily available coding software (see the Table of Materials), this program allows for the tracking of a single animal on both the open field grid and the ladder tests. In open field grid tracking, the code thresholds the video for intensity, tracks the position of the rat over the 3 min duration of the grid test, and analyzes the path. It then computes and returns measurements for the total distance traveled, the maximum velocity achieved, the number of left- and right-handed turns, and the total number of grid lines crossed by the rat. In ladder tracking, the code again thresholds the video for intensity, tracks the movement of the rat across the ladder, and returns calculated measurements including the time it took the rat to cross the ladder, the number of paw slips occurring below the plane of the ladder rungs, and the incidence of failures due to stagnation or reversals. We envision that the BVAS developed here can be employed for the analysis of motor function in a variety of applications, including many injury or disease models.

The current study aimed to automate the quantification of motor deficits in rats. The initial evaluation model assesses motor loss resulting from an intracortical microelectrode implantation in the motor cortex. We report on the development and use of a tracking algorithm using easily adaptable, simple, and readily available coding software.

Driving Under the Influence: How Music Listening Affects Driving Behaviors

Car driving is a daily activity for many individuals in modern societies. Drivers often listen to music while driving. The method presented here investigates how listening to music influences driving behaviors. A driving simulation was selected because it offers both a well-controlled environment and a good level of ecological validity. Driving behaviors were assessed through a car-following task. In practice, participants were instructed to follow a lead vehicle as they would do in real life. The lead vehicle speed changed over time requiring constant speed adjustments for the participants. The inter-vehicular time was used to assess driving behaviors. To complement the driving behaviors, the subjective mood and physiological level of arousal were also collected. As such, the results collected using this method offer insights on both the human internal state (i.e., subjective mood and physiological arousal) and driving behaviors in the car following task.

Here, we present a protocol to assess driving behaviors while following a vehicle in a simulated driving environment. The presented protocol is used to compare the impact of different auditory backgrounds on driving behaviors.

Characterization of the Sense of Agency over the Actions of Neural-machine Interface-operated Prostheses

This work describes a methodological framework that can be used to explicitly and implicitly characterize the sense of agency developed over the neural-machine interface (NMI) control of sensate virtual or robotic prosthetic hands. The formation of agency is fundamental in distinguishing the actions that we perform with our limbs as being our own. By striving to incorporate advanced upper-limb prostheses into these same perceptual mechanisms, we can begin to integrate an artificial limb more closely into the user&#39;s existing cognitive framework for limb control. This has important implications in promoting user acceptance, use, and effective control of advanced upper-limb prostheses. In this protocol, participants control a virtual prosthetic hand and receive kinesthetic sensory feedback through their preexisting NMIs. A series of virtual grasping tasks are performed and perturbations are systematically introduced to the kinesthetic feedback and virtual hand movements. Two separate measures of agency are employed: established psychophysical questionnaires (to capture the explicit experience of agency) and a time interval estimate task to capture the implicit sense of agency (intentional binding). Results of this protocol (questionnaire scores and time interval estimates) can be analyzed to quantify the extent of agency formation.

Here we present a protocol which characterizes the sense of agency developed over the control of sensate virtual or robotic prosthetic hands. Psychophysical questionnaires are employed to capture the explicit experience of agency, and time interval estimates (intentional binding) are employed to implicitly measure the sense of agency.

The HoneyComb Paradigm for Research on Collective Human Behavior

Collective human behavior such as group movement frequently shows surprising patterns and regularities, such as the emergence of leadership. Recent literature has revealed that these patterns, often visible at the global level of the group, are based on self-organized, individual behaviors that follow several simple local parameters. Understanding the dynamics of human collective behavior can help to improve coordination and leadership in group and crowd scenarios, such as identifying the ideal placement and number of emergency exits in buildings.
In this article, we present the experimental paradigm HoneyComb, which can be used to systematically investigate conditions and effects of human collective behavior. This paradigm uses a computer-based multi-user platform, providing a setting that can be shaped and adapted to various types of research questions. Situational conditions (e.g., cost-benefit ratios for specific behavior, monetary incentives and resources, various degrees of uncertainty) can be set by experimenters, depending on the research question. Each participant's motions are recorded by the server as hexagonal coordinates with timestamps at an accuracy of 50 ms and with individual IDs. Thus, a metric can be defined on the playfield, and movement parameters (e.g., distances, velocity, clustering, etc.) of participants can be measured over time. Movement data can in turn be combined with non-computerized data from questionnaires garnered within the same experiment setup.
The HoneyComb paradigm is paving the way for new types of human movement experiments. We demonstrate here that these experiments can render results with sufficient internal validity to meaningfully deepen our understanding of human collective behavior.

Here, we present the computer-based, multi-agent game HoneyComb, which enables experimental investigations of collective human movement behavior via black-dot-avatars on a virtual 2D hexagonal playfield. Different experimental conditions, like variable&#160;incentives on goal fields or vision radius, can be set, and their effects on human movement behavior can be investigated.

Applying Incongruent Visual-Tactile Stimuli during Object Transfer with Vibro-Tactile Feedback

The application of incongruent sensory signals that involves disrupted tactile feedback is rarely explored, specifically with the presence of vibrotactile feedback (VTF). This protocol aims to test the effect of VTF on the response to incongruent visual-tactile stimuli. The tactile feedback is acquired by grasping a block and moving it across a partition. The visual feedback is a real-time virtual presentation of the moving block, acquired using a motion capture system. The congruent feedback is the reliable presentation of the movement of the block, so that the subject feels that the block is grasped and see it move along with the path of the hand. The incongruent feedback appears as the movement of the block diverts from the actual movement path, so that it seems to drop from the hand when it is actually still held by the subject, thereby contradicting the tactile feedback. Twenty subjects (age 30.2 &#177; 16.3) repeated 16 block transfers, while their hand was hidden. These were repeated with VTF and without VTF (total of 32 block transfers). Incongruent stimuli were presented randomly twice within the 16 repetitions in each condition (with and without VTF). Each subject was asked to rate the difficulty level of performing the task with and without the VTF. There were no statistically significant differences in the length of the hand paths and durations between transfers recorded with congruent and incongruent visual-tactile signals &#8211; with and without the VTF. The perceived difficulty level of performing the task with the VTF significantly correlated with the normalized path length of the block with VTF (r = 0.675, p = 0.002). This setup is used to quantify the additive or reductive value of VTF during motor function that involves incongruent visual-tactile stimuli. Possible applications are prosthetics design, smart sport-wear, or any other garments that incorporate VTF.

We present a protocol to apply incongruent visual-tactile stimuli during an object transfer task. Specifically, during block transfers, performed while the hand is hidden, a virtual presentation of the block shows random occurrences of false block drops. The protocol also describes adding vibrotactile feedback while performing the motor task.

Tactile Semiautomatic Passive-Finger Angle Stimulator (TSPAS)

Passive tactile perception is the ability to passively and statically perceive stimulus information coming from the skin; for example, the ability to sense spatial information is the strongest in the skin on the hands. This ability is termed tactile spatial acuity, and is measured by the tactile threshold or discrimination threshold. At present, the two-point threshold is extensively used as a measure of tactile spatial acuity, although many studies have indicated that critical deficits exist in two-point discrimination. Therefore, a computer-controlled tactile stimulus system was developed, the tactile semiautomated passive-finger angle stimulator (TSPAS), using the tactile angle discrimination threshold as a new measure for tactile spatial acuity. The TSPAS is a simple, easily operated system that applies raised angle stimuli to a subject&#39;s passive fingerpad, while controlling movement speed, distance, and contact duration. The components of the TSPAS are described in detail as well as the procedure to calculate the tactile angle discrimination threshold.
