For those experiencing severe-to-profound sensorineural hearing loss, the cochlear implant (CI) is the preferred treatment. Augmented reality (AR) aided surgery can potentially improve CI procedures and hearing outcomes. Typically, AR solutions for image-guided surgery rely on optical tracking systems to register pre-operative planning information to the display so that hidden anatomy or other important information can be overlayed and co-registered with the view of the surgical scene. In this paper, our goal is to develop a method that permits direct 2D-to-3D registration of the microscope video to the pre-operative Computed Tomography (CT) scan without the need for external tracking equipment. Our proposed solution involves using surface mapping of a portion of the incus in surgical recordings and determining the pose of this structure relative to the surgical microscope by performing pose estimation via the perspective-n-point (PnP) algorithm. This registration can then be applied to pre-operative segmentations of other anatomy-of-interest, as well as the planned electrode insertion trajectory to co-register this information for the AR display. Our results demonstrate the accuracy with an average rotation error of less than 25 degrees and a translation error of less than 2 mm, 3 mm, and 0.55% for the x, y, and z axes, respectively. Our proposed method has the potential to be applicable and generalized to other surgical procedures while only needing a monocular microscope during intra-operation.
对于重度到永久性感音神经性听力损失患者来说，人工耳蜗（CI）是首选的治疗方法。增强现实（AR）辅助手术有可能改善人工耳蜗手术和听力效果。通常情况下，用于图像引导手术的 AR 解决方案依赖光学跟踪系统将术前规划信息注册到显示屏上，以便将隐藏的解剖结构或其他重要信息与手术场景的视图叠加并共同注册。在本文中，我们的目标是开发一种方法，允许显微镜视频与术前计算机断层扫描 (CT) 扫描进行二维到三维的直接配准，而无需外部跟踪设备。我们提出的解决方案包括使用手术记录中切口部分的表面映射，并通过透视-点（PnP）算法进行姿态估计，确定该结构相对于手术显微镜的姿态。然后，可将此配准应用于其他感兴趣解剖结构的术前分割以及计划的电极插入轨迹，以便为 AR 显示共同配准这些信息。我们的研究结果证明了这一方法的准确性，其 x、y 和 z 轴的平均旋转误差小于 25 度，平移误差分别小于 2 毫米、3 毫米和 0.55%。我们提出的方法有可能适用于并推广到其他外科手术中，同时在术中只需要一个单目显微镜。

In today's digital landscape, the Web has become increasingly centralized, raising concerns about user privacy violations. Decentralized Web architectures, such as Solid, offer a promising solution by empowering users with better control over their data in their personal `Pods'. However, a significant challenge remains: users must navigate numerous applications to decide which application can be trusted with access to their data Pods. This often involves reading lengthy and complex Terms of Use agreements, a process that users often find daunting or simply ignore. This compromises user autonomy and impedes detection of data misuse. We propose a novel formal description of Data Terms of Use (DToU), along with a DToU reasoner. Users and applications specify their own parts of the DToU policy with local knowledge, covering permissions, requirements, prohibitions and obligations. Automated reasoning verifies compliance, and also derives policies for output data. This constitutes a ``perennial'' DToU language, where the policy authoring only occurs once, and we can conduct ongoing automated checks across users, applications and activity cycles. Our solution is built on Turtle, Notation 3 and RDF Surfaces, for the language and the reasoning engine. It ensures seamless integration with other semantic tools for enhanced interoperability. We have successfully integrated this language into the Solid framework, and conducted performance benchmark. We believe this work demonstrates a practicality of a perennial DToU language and the potential of a paradigm shift to how users interact with data and applications in a decentralized Web, offering both improved privacy and usability.

Advances in ubiquitous computing have enabled end-user authoring of context-aware policies (CAPs) that control smart devices based on specific contexts of the user and environment. However, authoring CAPs accurately and avoiding run-time errors is challenging for end-users as it is difficult to foresee CAP behaviors under complex real-world conditions. We propose Fast-Forward Reality, an Extended Reality (XR) based authoring workflow that enables end-users to iteratively author and refine CAPs by validating their behaviors via simulated unit test cases. We develop a computational approach to automatically generate test cases based on the authored CAP and the user's context history. Our system delivers each test case with immersive visualizations in XR, facilitating users to verify the CAP behavior and identify necessary refinements. We evaluated Fast-Forward Reality in a user study (N=12). Our authoring and validation process improved the accuracy of CAPs and the users provided positive feedback on the system usability.
无处不在的计算技术的进步使得终端用户能够编写情境感知策略（CAP），根据用户和环境的特定情境来控制智能设备。然而，准确地编写 CAP 并避免运行时出错对终端用户来说是一项挑战，因为很难预见 CAP 在复杂的现实世界条件下的行为。我们提出了一种基于扩展现实（XR）的创作工作流程--Fast-Forward Reality，通过模拟单元测试案例验证 CAP 的行为，使最终用户能够反复创作和完善 CAP。我们开发了一种计算方法，可根据撰写的 CAP 和用户的上下文历史自动生成测试用例。我们的系统在 XR 中以身临其境的可视化方式提供每个测试用例，方便用户验证 CAP 行为并确定必要的改进。我们在一项用户研究（N=12）中对 Fast-Forward Reality 进行了评估。我们的编写和验证流程提高了 CAP 的准确性，用户对系统的可用性给予了积极反馈。

Recommender systems mainly tailor personalized recommendations according to user interests learned from user feedback. However, such recommender systems passively cater to user interests and even reinforce existing interests in the feedback loop, leading to problems like filter bubbles and opinion polarization. To counteract this, proactive recommendation actively steers users towards developing new interests in a target item or topic by strategically modulating recommendation sequences. Existing work for proactive recommendation faces significant hurdles: 1) overlooking the user feedback in the guidance process; 2) lacking explicit modeling of the guiding objective; and 3) insufficient flexibility for integration into existing industrial recommender systems. To address these issues, we introduce an Iterative Preference Guidance (IPG) framework. IPG performs proactive recommendation in a flexible post-processing manner by ranking items according to their IPG scores that consider both interaction probability and guiding value. These scores are explicitly estimated with iteratively updated user representation that considers the most recent user interactions. Extensive experiments validate that IPG can effectively guide user interests toward target interests with a reasonable trade-off in recommender accuracy. The code is available at https://github.com/GabyUSTC/IPG-Rec.

In the context of single domain generalisation, the objective is for models that have been exclusively trained on data from a single domain to demonstrate strong performance when confronted with various unfamiliar domains. In this paper, we introduce a novel model referred to as Contrastive Uncertainty Domain Generalisation Network (CUDGNet). The key idea is to augment the source capacity in both input and label spaces through the fictitious domain generator and jointly learn the domain invariant representation of each class through contrastive learning. Extensive experiments on two Single Source Domain Generalisation (SSDG) datasets demonstrate the effectiveness of our approach, which surpasses the state-of-the-art single-DG methods by up to $7.08%$. Our method also provides efficient uncertainty estimation at inference time from a single forward pass through the generator subnetwork.

Over the last 30 years, the World Wide Web has changed significantly. In this paper, we argue that common practices to prepare web pages for delivery conflict with many efforts to present content with minimal latency, one fundamental goal that pushed changes in the WWW. To bolster our arguments, we revisit reasons that led to changes of HTTP and compare them systematically with techniques to prepare web pages. We found that the structure of many web pages leverages features of HTTP/1.1 but hinders the use of recent HTTP features to present content quickly. To improve the situation in the future, we propose fine-grained content segmentation. This would allow to exploit streaming capabilities of recent HTTP versions and to render content as quickly as possible without changing underlying protocols or web browsers.

Model extraction attacks (MEAs) enable an attacker to replicate the functionality of a victim deep neural network (DNN) model by only querying its API service remotely, posing a severe threat to the security and integrity of pay-per-query DNN-based services. Although the majority of current research on MEAs has primarily concentrated on neural classifiers, there is a growing prevalence of image-to-image translation (I2IT) tasks in our everyday activities. However, techniques developed for MEA of DNN classifiers cannot be directly transferred to the case of I2IT, rendering the vulnerability of I2IT models to MEA attacks often underestimated. This paper unveils the threat of MEA in I2IT tasks from a new perspective. Diverging from the traditional approach of bridging the distribution gap between attacker queries and victim training samples, we opt to mitigate the effect caused by the different distributions, known as the domain shift. This is achieved by introducing a new regularization term that penalizes high-frequency noise, and seeking a flatter minimum to avoid overfitting to the shifted distribution. Extensive experiments on different image translation tasks, including image super-resolution and style transfer, are performed on different backbone victim models, and the new design consistently outperforms the baseline by a large margin across all metrics. A few real-life I2IT APIs are also verified to be extremely vulnerable to our attack, emphasizing the need for enhanced defenses and potentially revised API publishing policies.
模型提取攻击（MEAs）使攻击者只需远程查询受害深度神经网络（DNN）模型的 API 服务，就能复制该模型的功能，这对基于按查询付费的 DNN 服务的安全性和完整性构成了严重威胁。尽管目前有关 MEA 的大部分研究主要集中在神经分类器上，但在我们的日常活动中，图像到图像翻译（I2IT）任务越来越普遍。然而，为 DNN 分类器开发的 MEA 技术无法直接应用于 I2IT 案例，这使得 I2IT 模型易受 MEA 攻击的程度往往被低估。本文从一个新的角度揭示了 I2IT 任务中的 MEA 威胁。与弥合攻击者查询和受害者训练样本之间分布差距的传统方法不同，我们选择减轻不同分布造成的影响，即所谓的领域偏移。为此，我们引入了一个新的正则化项，用于惩罚高频噪声，并寻求一个更平坦的最小值，以避免对偏移分布的过度拟合。我们在不同的骨干受害者模型上对不同的图像翻译任务（包括图像超分辨率和风格转换）进行了广泛的实验，在所有指标上，新设计都远远优于基线设计。经验证，一些现实生活中的 I2IT 应用程序接口也极易受到我们的攻击，这强调了增强防御和可能修订应用程序接口发布政策的必要性。

This paper explores the integration of causal pathway diagrams (CPD) into human-centered design (HCD), investigating how these diagrams can enhance the early stages of the design process. A dedicated CPD plugin for the online collaborative whiteboard platform Miro was developed to streamline diagram creation and offer real-time AI-driven guidance. Through a user study with designers (N=20), we found that CPD's branching and its emphasis on causal connections supported both divergent and convergent processes during design. CPD can also facilitate communication among stakeholders. Additionally, we found our plugin significantly reduces designers' cognitive workload and increases their creativity during brainstorming, highlighting the implications of AI-assisted tools in supporting creative work and evidence-based designs.

Communicating design implications is common within the HCI community when publishing academic papers, yet these papers are rarely read and used by designers. One solution is to use design cards as a form of translational resource that communicates valuable insights from papers in a more digestible and accessible format to assist in design processes. However, creating design cards can be time-consuming, and authors may lack the resources/know-how to produce cards. Through an iterative design process, we built a system that helps create design cards from academic papers using an LLM and text-to-image model. Our evaluation with designers (N=21) and authors of selected papers (N=12) revealed that designers perceived the design implications from our design cards as more inspiring and generative, compared to reading original paper texts, and the authors viewed our system as an effective way of communicating their design implications. We also propose future enhancements for AI-generated design cards.
