We propose a new method of presenting two-dimensional information, such as figures and graphs, on a tactile display so that visually impaired people are able to perceive them quickly and accurately. The new presentation method is developed for a tactile-proprioceptive display, which can present information on not only conventional "concave-convex" tactile display, but also vibration presentation in arbitrary area on a tactile display and mechanical leading presentation by mechanically leading user's fingers using haptic device. In this paper, we outline the abovementioned two presentation method and the developed tactile-prop display, and objectively evaluate the effects of the local area vibration presentation method as an integral part of the tactile-prop display in comparison with the conventional "concave-convex" presentation method. We conducted experiments to evaluate the effects of the proposed local area vibration presentation method using two typical content patterns. In Experiment 1, discreetly dispersed objects are searched, and in Experiment 2, the cross graphs of line segments are distinguished and perceived. The experiments have proved that the method is effective in reducing search and cognitive time as well as identifying the correct cognition of cross graphs, as compared to the "concave-convex" tactile presentation method.

This paper reports the results of usability evaluation based on the predictive human performance models applied to any products, and introduces application of a tool for predicting operational time to an IP phone and an electronic health record system UI consulting. We assessed effectiveness of this tool using efficiency estimation technique and extracted the practical the practical problems. In the human interface (HI) consultation process, as the tool predicts execution time of the current version and of the improved version, the improvement effect could be assessed. For an IP phone, we created the modified user interface designs from the point view of operational efficiency, so that we could indicate effectiveness of this tool by comparing task execution time. For an electronic health records, however, it is difficult to "directly" verify the effectiveness of the modified user interface designs from an efficiency standpoint. Through an evaluation scenario, the tool provided data that is necessary for assessment of improvement in this case. © 2011 Springer-Verlag.

In this paper, we introduce Block Jam, a Tangible User interface that controls a dynamic polyrhythmic sequencer using 26 physical artifacts. These physical artifacts, that we call blocks, are a new type of input device for manipulating an interactive music system. The blocks’ functional and topological statuses are tightly coupled to an ad hoc sequencer, interpreting the user’s arrangement of the blocks as meaningful musical phrases and structures. We demonstrate that we have created both a tangible and visual language that enables both the novice and musically trained users by taking advantage of both their explorative and intuitive abilities. The tangible nature of the blocks and the intuitive interface promotes face-to-face collaboration and social interaction within a single system. The principle of collaboration is further extended by linking two Block Jam systems together to create a network. We discuss our project vision, design rational, related works, and the implementation of Block Jam prototypes. © 2003, Steering Committee of the International Conference on New interfaces for Musical Expression.

Robust point feature matching in projective space

Conference on computer Vision and Pattern Recognition (CVPR)

ISBN: (纸本)0769512720

We present a robust method for matching point features across a set of images under full perspective projection. An expectation-maximization-like algorithm is developed to build an optimal potential match set (PMS) between each consecutive pair of views, by iteratively maximizing a heuristic objective function. All two-view matches are combined to form an M-view potential match set (MPMS) with a low contamination rate. Outliers in MPMS are removed incorporating the least-median-of-squares technique with projective reconstruction. The current work extends previous ones in two- or three-view matching, or under affine camera projection. Results on real imagery demonstrate the validity of the proposed method.

Support vector machines represent a new approach to pattern classification developed from the theory of structural risk minimization. In this paper, we present an investigation into the application of support vector machines to the confidence measurement problem in speech recognition. Specifically, based on the results from an initial decoding of an utterance during speech recognition, we derive a feature vector consisting of parameters such as word score density, N-best word score density differences, relative word score and relative word duration as input to the confidence measurement process in which hypothetically correct utterances are accepted and utterances determined to be incorrect are rejected. We propose a new approach to training support vector machines. In this paper, we train and test a support vector machines classifier and compare the results with other statistical classification methods.

We consider the problem of broadcasting a bandlimited white Gaussian source on an additive bandlimited white Gaussian noise channel with two receivers. Several hybrid digital-analog joint source-channel codes are proposed. The design principle is based on bandwidth/power splitting and matched tandem coding. The distortion regions of these codes are presented.

We present the system called Takealook, which personalizes information presentation according to the user's interests and knowledge. The system infers the user's interests from her/his question-and-answer interactions and the information presenters' conceptual spaces by using the related method of collaborative filtering. It then provides additional information about current contents and also recommends other related contents. The user's interests are represented by her/his own individual conceptual space (i.e., a set of related keywords) which is adapted to her/his preferences. In this paper we describe a method for personalizing the information presentation, implementating the system at reviewing an exhibition, and experimental results.

作者： Y. Miyazaki K. Nahrstedt Human Interface Laboratories Nippon Telegraph and Telephone Corporation Yokosuka Japan Department of Computer Science University of Illinois Urbana-Champaign Urbana IL USA

We have designed and implemented a video on demand (VOD) system over heterogeneous wide area networks (WAN). The hierarchical architecture is an effective way to build such a system. One of the most important and still open issues in a hierarchical VOD system is how to arrange system resources for better performance corresponding to various applications. Our approach is to coordinate movie files dynamically according to their popularity index and resource availability. We present our system and protocol designs to support the dynamic coordination. We also describe our experimental results. Our approach gives a practical solution to VOD services on current network architecture such as the Internet.

Until 1992 he was a Senior Research Engineer Supervisor at W Human Interface Laboratories and conducted research on human image recognition with a special interest in face recognition. Since 1992 he has been with ATR Human Information Processing Research Laboratories Kyoto Japan where he is currently Head of Department 2. His research interests include computational and cognitive studies on high-level vision with a special interest in facial information processing by man and computer. He is a member of the Institute of Electronics Information and Communication Engineers of Japan the Information Processing Society of Japan ACM and the IEEE Computer Society. Hidm Fukamachi received his B.E. degree in Image Technology from the Tokyo Institute of Polytechnics in 1990. He joined NTT Software Corp. in 1990 where he was engaged in the development of image processing software. Since 1993 he has been with ATR Human Information Processing Research Laboratories.

Some facial images are not necessarily clear images in the human brain. However, it can be easily judged whether a face matches the image in our mind;this is true even when the drawing or the expression of the target image is difficult to comprehend. This is because even if the image cannot be imagined like a picture, it does exist. The authors have proposed a system with which a retriever can retrieve an ambiguous target image from an image database. The system's retrieval efficiency and ease-of-retrieval were clarified by experiments using line drawn facial images. In this paper, the system is extended to photographs of faces. The most difficult problem in treating photographs is determining the retrieval key. One consideration is to add the subjective impressions or features of physical figures as keywords for each image data. Regardless of the method, however, significant manpower is necessary. The K-L expansion technique is used here, which has been verified as effective for face identification, and expect to need only a small amount of manpower. This paper investigates whether the technique can also be useful in ambiguous image retrieval.
