Open-source software projects have become an integral part of our daily life, supporting virtually every software we use today. Since open-source software forms the digital infrastructure, maintaining them is of utmost importance. We present Climate Coach, a dashboard that helps open-source project maintainers monitor the health of their community in terms of team climate and inclusion. Through a literature review and an exploratory survey (N=18), we identified important signals that can reflect a project’s health, and display them on a dashboard. We evaluated and refined our dashboard through two rounds of think-aloud studies (N=19). We then conducted a two-week longitudinal diary study (N=10) to test the usefulness of our dashboard. We found that displaying signals that are related to a project’s inclusion help improve maintainers’ management strategies.
开源软件项目已经成为我们日常生活中不可或缺的一部分,几乎支持着我们今天使用的所有软件。由于开源软件构成了数字基础设施,维护它们是至关重要的。我们介绍了Climate Coach,这是一个仪表板,可以帮助开源项目维护者在团队氛围和包容性方面监控社区的健康状况。通过文献回顾和探索性调查(N=18),我们确定了可以反映项目健康状况的重要信号,并将它们显示在仪表板上。我们通过两轮有声思考研究(N=19)来评估和完善我们的仪表板。然后,我们进行了为期两周的纵向日记研究(N=10),以测试我们的仪表板的有用性。我们发现显示与项目包含相关的信号有助于改进维护者的管理策略。

Orthoses with electronic functions have emerged as a promising medical product in response to the increasing demand for rehabilitation training, therapy assistance, and health monitoring. However, fabricating this “smart orthosis” often requires long development cycles and exorbitant prices. We introduce E-Orthosis, an integrated fabrication approach with construction toolkits for healthcare professionals to quickly embed electronics in off-the-shelf orthoses with customized functions cost-effectively and time-efficiently. Specifically, we develop components with magnets and pogo pins to support rapid attachment and sustainable use, and textile-based electrodes with snap installation to improve the wearing experience. We also provide a circuit iron tool to apply circuit traces on complex surfaces of orthoses directly and a hot punch tool to embed magnet ports and electrodes. Three application examples, technical evaluations, and expert reviews demonstrate the functionality of E-Orthosis and the potential for democratizing rapid-developed and low-cost smart orthoses for patients.
随着人们对康复训练、治疗辅助和健康监测的需求不断增加,具有电子功能的矫形器已成为一种有前景的医疗产品。然而,制造这种“智能矫形器”通常需要很长的开发周期和高昂的价格。我们推出了E-Orthosis,这是一种集成的制造方法,为医疗保健专业人员提供了构建工具包,可以快速将电子设备嵌入到具有定制功能的现成矫形器中,具有成本效益和时间效益。具体来说,我们开发了带有磁铁和弹簧脚的组件,以支持快速附着和可持续使用,以及带有快速安装的基于纺织品的电极,以改善佩戴体验。我们还提供了一种电路铁工具,可以直接在矫形器的复杂表面上应用电路轨迹,以及一种热冲孔工具,可以嵌入磁铁端口和电极。三个应用实例、技术评估和专家评论展示了E-Orthosis的功能,以及为患者普及快速开发和低成本智能矫形器的潜力。

Why I Can’t Authenticate — Understanding the Low Adoption of Authentication Ceremonies with Autoethnography 为什么我不能认证——理解自我民族志认证仪式的低采用率
Pub Date : 2023-04-19 DOI: 10.1145/3544548.3581508

Authentication ceremonies detect and mitigate Man-in-the-Middle (MitM) attacks on end-to-end encrypted messengers, such as Signal, WhatsApp, or Threema. However, prior work found that adoption remains low as non-expert users have difficulties using them correctly. Anecdotal evidence suggests that security researchers also have trouble authenticating others. Since their issues are probably unrelated to user comprehension or usability, the root causes may lie deeper. This work explores these root causes using autoethnography. The first author kept a five-month research diary of their experience with authentication ceremonies. The results uncover points of failure while planning and conducting authentication ceremonies. They include cognitive load, forgetfulness, social awkwardness, and explanations required by a communication partner. Additionally, this work identifies and discusses how sociocultural aspects affect authentication ceremonies. Lastly, this work discusses a design approach for cooperative security that employs cultural transcoding to improve sociocultural aspects of security by design.
身份验证仪式检测并减轻对端到端加密信使(如Signal、WhatsApp或Threema)的中间人(MitM)攻击。然而,先前的工作发现,采用率仍然很低,因为非专业用户很难正确使用它们。坊间证据表明,安全研究人员在验证他人身份方面也存在困难。由于它们的问题可能与用户理解或可用性无关,因此根本原因可能更深。这项工作探讨了这些根本原因使用自身民族志。第一作者用五个月的时间记录了他们在认证仪式上的经历。结果揭示了计划和执行认证仪式时的故障点。它们包括认知负荷、健忘、社交尴尬和沟通伙伴要求的解释。此外,这项工作确定并讨论了社会文化方面如何影响认证仪式。最后,本文讨论了一种采用文化转码的合作安全设计方法,通过设计来改善安全的社会文化方面。

Automatic stress tracking has become increasingly available on wearable devices. Research has investigated its use for individual stress management, largely within the traditional data-as-care framing. However, its use for stress sharing in social relationships, particularly close relationships, is still under explored. Inspired by the idea of “caring-through-data”, which focuses on mediating the social and emotional experiences of the collective “us” with data, this paper presents a design study with a prototype called IntimaSea, a display featuring illustrative stress data in collective forms to be shared among close relationships. The field trials with nine groups of intimately-connected users (N=19) highlight its potential on stress awareness, interpretation and management, as well as intimacy promotion. We end by discussing sharing stress for social ways of stress management, stress data as a meaningful social cue mediating relationships, as well as design implications for caring-through-data.
自动应力跟踪在可穿戴设备上的应用越来越广泛。研究调查了它在个人压力管理中的应用,主要是在传统的数据即护理框架内。然而,它在社会关系,特别是亲密关系中分担压力的作用仍在探索中。“关爱数据”(caring-through-data)的理念侧重于通过数据来调解集体“我们”的社会和情感体验,本文的灵感来自于一个名为IntimaSea的设计研究原型,这是一个展示集体形式的说明性压力数据的展示,可以在亲密关系中共享。对9组密切联系的用户(N=19)进行的实地试验突出了其在压力意识、解释和管理以及亲密关系促进方面的潜力。最后,我们讨论了压力管理的社会方式共享压力,压力数据作为有意义的社会线索中介关系,以及关心数据的设计含义。

Information workers often struggle to balance their time for a variety of activities like focused work, communication, and caring. This study analyzes the impact of a commercially available computer-assisted time protection intervention that automatically and preemptively schedules calendar time for self-determined activities. We analyzed the behaviors and self-reports of workers in two naturalistic studies. First, we studied 27 workers who were already using Computer-Assisted Protected Time (CAP time) and found that they mainly used it for focused work. Second, we analyzed the effect of CAP time as a randomized intervention on 89 workers who never had CAP time and found that those with it self-reported an increase in performance, job resources, and immersion. In both studies, workers with CAP time exhibited a rearrangement of activities leading to an overall reduction in work activity. This study highlights new opportunities for intelligent time-management interventions and the importance of protected time at work.
信息工作者经常努力平衡他们的时间来进行各种活动,如集中工作、交流和关怀。本研究分析了市售计算机辅助时间保护干预的影响,该干预可以自动和先发制人地为自行决定的活动安排日历时间。我们在两项自然主义研究中分析了工人的行为和自我报告。首先,我们研究了27名已经使用计算机辅助保护时间(CAP时间)的员工,发现他们主要将其用于集中工作。其次,我们分析了CAP时间作为随机干预对89名从未有过CAP时间的员工的影响,发现那些有CAP时间的员工自我报告在绩效、工作资源和沉浸度方面都有所提高。在这两项研究中,有CAP时间的工人表现出活动的重新安排,导致工作活动的总体减少。这项研究强调了智能时间管理干预的新机遇,以及保护工作时间的重要性。

Selecting a proper color palette is critical in crafting a high-quality graphic design to gain visibility and communicate ideas effectively. To facilitate this process, we propose De-Stijl, an intelligent and interactive color authoring tool to assist novice designers in crafting harmonic color palettes, achieving quick design iterations, and fulfilling design constraints. Through De-Stijl, we contribute a novel 2D color palette concept that allows users to intuitively perceive color designs in context with their proportions and proximities. Further, De-Stijl implements a holistic color authoring system that supports 2D palette extraction, theme-aware and spatial-sensitive color recommendation, and automatic graphical elements (re)colorization. We evaluated De-Stijl through an in-lab user study by comparing the system with existing industry standard tools, followed by in-depth user interviews. Quantitative and qualitative results demonstrate that De-Stijl is effective in assisting novice design practitioners to quickly colorize graphic designs and easily deliver several alternatives.
选择合适的调色板对于制作高质量的图形设计至关重要,以获得可见性并有效地传达想法。为了促进这一过程,我们提出了De-Stijl,一个智能和交互式的色彩创作工具,以帮助新手设计师制作和谐的调色板,实现快速的设计迭代,并满足设计约束。通过De-Stijl,我们提供了一种新颖的2D调色板概念,使用户能够直观地感知颜色设计的比例和接近度。此外,De-Stijl实现了一个整体的色彩创作系统,该系统支持2D调色板提取,主题感知和空间敏感的颜色推荐,以及自动图形元素(重新)着色。我们通过实验室用户研究来评估De-Stijl,将系统与现有的行业标准工具进行比较,然后进行深入的用户访谈。定量和定性结果表明,De-Stijl可以有效地帮助设计新手快速为图形设计上色,并轻松地提供多种替代方案。

Ultrasound mid-air haptic technology provides a large space of design possibilities, as one can modulate the ultrasound intensity in a continuous 3D space at a high speed over time. Yet, the need for programming the patterns limits rapid ideation and testing of alternatives. We present Feellustrator, a graphical design tool for quickly creating and editing ultrasound mid-air haptics. With Feellustrator, one can create custom ultrasound patterns, layer or sequence them into complex effects, project them on the user’s hand, and export them for use in external programs (e.g., Unity). To create the tool, we interviewed 13 designers who had from a few months to several years of experience with ultrasound, then derived a set of requirements for supporting ultrasound design. We demonstrate the design power of Feellustrator through example applications and an evaluation with 15 participants. Then, we outline future directions for ultrasound haptic design.
超声半空触觉技术提供了很大的设计可能性空间,因为人们可以随着时间的推移在连续的3D空间中高速调制超声强度。然而,对模式进行编程的需要限制了对备选方案的快速构思和测试。我们提出了Feellustrator,一个图形设计工具,用于快速创建和编辑超声半空触觉。与Feellustrator,一个可以创建自定义超声模式,层或序列成复杂的效果,投射到用户的手上,并导出它们用于外部程序(例如,Unity)。为了创建这个工具,我们采访了13位有几个月到几年超声经验的设计师,然后得出了一组支持超声设计的要求。我们通过示例应用和15名参与者的评估来展示Feellustrator的设计能力。展望了超声触觉设计的发展方向。

A novel interaction for competence assessment using micro-behaviors:: Extending CACHET to graphs and charts 一种利用微行为进行能力评估的新型交互:将CACHET扩展到图形和图表

Competence Assessment by Chunk Hierarchy Evaluation with Transcription-tasks (CACHET) was proposed by Cheng [14]. It analyses micro-behaviors captured during cycles of stimulus viewing and copying in order to probe chunk structures in memory. This study extends CACHET by applying it to the domain of graphs and charts. Since drawing strategies are diverse, a new interactive stimulus presentation method is introduced: Transcription with Incremental Presentation of the Stimulus (TIPS). TIPS aims to reduce strategy variations that mask the chunking signal by giving users manual element-by-element control over the display of the stimulus. The potential of TIPS, is shown by the analysis of six participants transcriptions of stimuli of different levels of familiarity and complexity that reveal clear signals of chunking. To understand how the chunk size and individual differences drive TIPS measurements, a CPM-GOMS model was constructed to formalize the cognitive process involved in stimulus comprehension and chunk creation.
基于转录任务的Chunk Hierarchy Evaluation with transcriptional -tasks (CACHET)能力评估方法由Cheng等人提出。它分析在刺激观察和复制周期中捕获的微行为,以探测内存中的块结构。本研究将CACHET扩展到图形和图表领域。由于绘制策略的多样性,提出了一种新的交互式刺激呈现方法:刺激增量呈现转录(TIPS)。TIPS旨在通过让用户对刺激的显示进行逐个元素的手动控制,减少掩盖分块信号的策略变化。通过对六名参与者不同熟悉程度和复杂程度的刺激转录的分析,揭示了组块化的清晰信号,表明了TIPS的潜力。为了了解块大小和个体差异如何驱动TIPS测量,我们构建了CPM-GOMS模型来形式化涉及刺激理解和块创建的认知过程。

This study extends CACHET by applying it to the domain of graphs and charts. Since drawing strategies are diverse, a new interactive stimulus presentation method is introduced: Transcription with Incremental Presentation of the Stimulus (TIPS). TIPS aims to reduce strategy variations that mask the chunking signal by giving users manual element-by-element control over the display of the stimulus.

Advances in intimate care technologies and on-body wearables are disrupting how and where we think about and care for our bodies. The boundaries between private and public are increasingly porous. This offers new sites for studying intimate care as technology-use-in-practice. We present a qualitative study on the use of breast pumps in the workplace, based on semi-structured interviews with 19 individuals. Through this, we contribute an illustration of the complexities in carrying out intimate care work at the workplace and what it means to be pumping at the workplace. Our analysis unpacks (in)visibility as a crucial tension in the use of breast pumps in the workplace. We discuss how (in)visibility of personal medical devices plays a mediating role in how individuals exercise bodily rights, and the norms of who fits into professional settings.
亲密护理技术和穿戴式设备的进步正在颠覆我们思考和护理身体的方式和地点。私人和公共部门之间的界限越来越模糊。这为研究亲密护理作为技术在实践中的应用提供了新的场所。我们提出了一项关于在工作场所使用吸奶器的定性研究,基于对19个人的半结构化访谈。通过这一点,我们阐述了在工作场所进行亲密护理工作的复杂性,以及在工作场所抽水意味着什么。我们的分析揭示了在工作场所使用吸奶器时,可见性是一个至关重要的张力。我们讨论了个人医疗设备的可见性如何在个人如何行使身体权利方面发挥中介作用,以及谁适合专业设置的规范。
