We investigated a classification method using brain computer interfaces (BCIs) for silent speech. Event-related potentials (ERPs) obtained when four subjects imagined the vocalization of two Japanese vowels while they remained silent and immobilized were recorded. We used an adaptive collection (AC) that adaptively selects suitable output signals of common spatial patterns (CSP) filters and its time duration for classification. The classification accuracies (CAs) were 73-92% for the pairwise classification /a/ vs. /u/ in the use of 63 channels and significantly better than previous study.
研究了一种基于脑机接口(bci)的无声言语分类方法。记录了4名被试在静止不动状态下想象两个日语元音发声时的事件相关电位(event - associated potential, ERPs)。我们使用自适应采集(AC)，自适应地选择合适的公共空间模式(CSP)滤波器的输出信号及其持续时间进行分类。在63个通道中，/a/ vs /u/两两分类的分类准确率(CAs)为73 ~ 92%，明显优于前人的研究。

Emotions can be regulated to fit a task in order to enhance task performance. Motor expressions can help regulate emotion. This paper briefly reports ongoing work on the design of physical interactions based on motor expressions that can help regulate emotion to fit a task. We argue that to be effective, such interactions must be made meaningful in relation to ongoing appraisal processes, and that such interactions can help regulate emotion via congruence, suppression, or incompatibility. We present previous work on the validation of these arguments within the context of supporting idea generation, and develop a roadmap for research that aims to translate these results to the design of physical interactions under device constraints. The research will enable designers of interactive technology to develop physical interactions that help regulate emotion with the aim to help people get the most out of their own capabilities.

Autonomous systems perform tasks without human guidance. Techniques for making autonomous systems scrutable and, hence, more transparent are required in order to support humans working with such systems. The Scrutable Autonomous Systems (SAsSy) demo shows a novel way of combining argumentation and natural language to generate a human understandable explanation dialogue. By interacting with SAsSy users are able to ask why a certain plan was selected for execution, why other alternatives were not selected, also allowing users to modify information in the system.

In this paper, we propose an interaction system which displays see-through images on the mobile display and that allows a user to interact with virtual objects overlaid on the see-through image using the user's hand. In this system, the camera which tracks the user's viewpoint is attached to the front of the mobile display and the depth camera which captures color and depth images of the user's hand and the background scene is attached to the back of the mobile display. Natural interaction with virtual objects using the user's hand is realized by displaying images so that the appearance of a space through the mobile display is consistent with that of the real space from the user's viewpoint. We implemented two applications to the system and showed the usefulness of this system in various AR applications.

This paper introduces a novel method for detecting and modeling intentions of students performing training tasks in a Virtual Reality (VR) environment enhanced with intelligent tutoring capabilities. Our VR-setup provides students with an immersive user interface, but produces noisy and low-level input, from which we need to recognize higher-level cognitive information about the student. The complexity of this task is amplified by the requirements of the target domain (child pedestrian safety), where students need to train complex skills in dynamic settings. We present an approach for this task, which combines the logic-based Event Calculus (EC) and probabilistic modeling.

In this work, we present a demonstration of a visual interactive tool called ESSAVis that helps different engineers in collaborating together for understanding the failure mechanisms in complex embedded systems. ESSAVis provides a 2Dplus3D visual user interface that integrates intuitively between different data sets related with embedded systems failure mechanisms. The tool accepts a CFT model describing a specific hazard in the underlying system, and a CAD model describing the geometry of system components. In this paper, we present different interaction options of ESSAVis that are used for intuitively extracting safety aspects of the underlying embedded system.

Exploratory search of scientific literature plays an essential part of a researcher's work. Efforts to provide interfaces supporting this task accomplished significant progress, but the field is open for further evolution. In this paper I present four basic design concepts identified in exploratory search interfaces: relevance, diversity, relationships and categories, and propose a novel browsing layout featuring a unique combination of these concepts.

Facial expressions play a crucial role in human interaction. Interactive digital games can help teaching people to both express and recognise them. Such interactive games can benefit from the ability to alter user expressions dynamically and in real-time. In this demonstration, we present the Facial Affect Mapping Engine (FAME), a framework for mapping and manipulating facial expressions across images and video streams. Our system is fully automatic runs in real-time and does not require any specialist hardware. FAME presents new possibilities for the designers of intelligent interactive digital games.

Social communities play an important role in many domains. While a lot of attention has been given to developing efficient methods for detecting and analyzing social communities, it still remains a great challenge to provide intuitive search interfaces for end-users who wish to discover and explore such communities. Trying to fill the gaps, in this demonstration we present Microcosm: a holistic solution for visual discovery, exploration and analysis of social communities.

Many small and mid-sized e-businesses wish to integrate a recommender system into their website. Integrating an existing recommender system to a website often requires certain expertise and programming efforts, thus incurs substantial investments and may not be justified by the added value of the recommender system. This demo presents a solution for integrating a recommender system as a service to an existing e-business without any programming efforts. The integration method is analogue to the way of the Google AdSense integration and the business model is adapted from the advertisements world. Initial feedback from real website owners indicates that such integration has a great benefit for both sides; the website owner and the Recommender System (RS) provider.
