Human Interface Lab. is consisted of four faculty members. Each member has own interest and are doing independent research activities; Prof. Masahide Sugiyama: Participated in Open Campus with lab demonstrations. Promoted a series of computer training courses for visual handicapped people in Aizu region. Prof. Michel Cohen: Participated in Open Campus and Open Lab programs with lab demonstrations. Presented public lecture with students (Saturday, December 18, 2004: "Spatial Media: 3D Computer Graphics and Audio"; http://www.u-aizu.ac.jp/~mcohen/spatial-media/koukaikouzas/2004-5/program.html). Chaired "IWSM: 5th Int. Workshop on Spatial Media" (Nov. 11, 2004: http://www.u-aizu.ac.jp/~mcohen/welcome/IWSM/04/program.html) Prof. Jie Huang: Computational Auditory Scene Analysis There was intensive research on the integration and segregation factors for sound component self organization. We conducted some examinations on the interactions between di??erent primary cues for sound integration and segregation in human auditory systems by psychological experiments and tried to find out quantitative relations for computational auditory scene analysis. Robotic Spatial Sound Localization We developed a robotic spatial sound localization system using an auditory interface with four microphones arranged on the surface of a spherical robot head. The time difference and intensity difference from a sound source to different microphones are analyzed by measuring the HRTFs around the spherical head in an anechoic chamber. Robot Position Identification We proposed a visual position identification method using colored rectangle signboards for a multimodal mobile robot which is designed to work in a room environment. The rectangle signboards are placed in several known positions. By calculate the vanishing points in the image of the signboard, it is possible to obtain the relative direction between the signboard and the robot by a single image, the distance from the robot to the signboard can also be calculated.

	In this paper we investigate the interpretation of kansei properties for the perception of American English vowel sounds. A universal perceptual space for ten American English vowel sounds was derived for two groups of listeners, a group of native speakers of the American English, and a group of native speakers of the Japanese. The stimuli used in the experiment were the ten American English vowel sounds synthesized using the often utilized formant frequency values published by Peterson and Barney in 1952. Subsets of these two groupsmade ratings on 12 kansei bipolar adjective scales for the same set of sounds, each of the two groups using anchoring adjectives taken from their native language. Though there was no evidence of any difference between the two groups in their indscal-derived perceptual dimensions for these vowel sounds, the adjectives were used differently in describing kansei reactions, those same perceptual dimensions by the two groups. Key words: Kansei properties, perceptual space, semantic differential analysis.

	A universal perceptual space for 10 American English vowel sounds was derived for two groups of listeners| a group of native speakers of English and a group of native speakers of Japanese. Subsets of these two groups made ratings on 12 bipolar adjective scales for the same set of sounds, each of the two groups using anchoring adjectives taken from their native language. Although there was no evidence of any difference between the two groups in their INDSCAL-derived perceptual dimensions for these vowel sounds, the adjectives were used differently in describing those same perceptual dimensions by the two groups. Though a few of the adjectives were used to describe similar perceptual variations, language typological implications of this investigation is that caution be exercised in generalizing semantic differential ratings obtained in one language, especially when those ratings are intended to aid in the interpretation of data from listeners speaking a different native language. Keywords: universal perceptual space, language typology, and semantic di??erential analysis.

	This study examines multilingual subjects' perceptual similarityand semantic relation in order to find universals of languages. Two Indo-European languages (English and Bengali) and one non-Indo-European language (Japanese) were used. A common perceptual space was obtained through Multidimensional Scaling (mds) analysis method. In contrast, semantic approach was taken using Semantic Differential Analysis (sda) method. Apart from these, a least square mapping method, Procrustes analysis, was also employed to determine whether semantic scales relate differently to the dimensions of the common perceptual space that did not differ between these three groups of languages. Breaking the tradition of taking vowel sounds to find relation between languages, however, a sophisticated approach was taken by having six guitar sounds as stimuli, which could be considered as a common parameter for all subjects of different groups of languages. Ten topic-dependent bipolar adjective scales on which responses are taken, were constructed in a preliminary study. The results of the sda analysis showed that the English, and Japanese semantic scales related differently to the mds derived common perceptual space, while the Bengali semantic scales related somewhat similarly to the same commonperceptual space. And also Procrustes Analysis revealed that the Bengali factor space is closer to the English factor space than to the Japanese factor space. With regard to the potential for generalizing semantic differential ratings obtained in one language to aid in the interpretation of data from listeners speaking a different native language, the results of the current study suggest that caution be exercised. Moreover the results of this study suggest that interpreters will have to be cautiously attentive in interpretation of data from Indo-European family of languages (English and Bengali) to non Indo-European family of languages (Japanese).

	Voice Over Internet Protocol (VoIP) has been marked as the next 'killer disruptive technology.' Several protocols have been proposed for VoIP session control; H.323 and sip are the most significant. Sip, the Session Initiation Protocol, is a signaling protocol for internet conferencing, telephony, presence applications, event notification, and instant messaging. This article reports observed VoIP traffic when clients are in a lan, a wan, and in a hybrid network with an adsl link. The deployed architecture consists of a sip server (with registrar, proxy, and presence functions) and two sip clients. Using a traffic analyzer, we monitored the sip messages as well as the real-time quality, measured in the form of delay, packet loss, and jitter.

	We describe a unique midi-based spatial sound system featuring a network-driven bank of four RSS-10s (Roland Sound Space Processors) driving a eight-transducer circumferential speaker array in a "3d Theater", enabling a three-dimensional dynamic musical space. Sound sources can be choreographed by adding dynamic positional gestures to standard midi files. Our sequencing system interprets such files, partitioning their data into two streams: one for midi tonal events, sent to synthesizers, and the other for positional data, sent simultaneously to sound spatializers, clients in a multimodal heterogeneous collaborative virtual environment. This research achieves programmed and interactive musical control of sound localization, synchronizable with stereographic 3D contents, spatializing music to give real presence to an audience.

	Design and implementation of a universal platform based upon mobile telephony and the internet infrastructure for healthcare monitoring and other related applications is described. The platform hierarchy comprises three layers for sensing, communication, andmanagement. The core of the sensing layer is a wearable sensor unit suitable for vital signs monitoring without discomfort and constraint during daily activities. The communication layer conducts bi-directionaldata/commandsignals via either wired or wirelessmeansto bridge layers communication between the sensor and management layers. The management layer performs data mining and functional assessment. This article describes the architecture design consideration and systemic implementation to meet various practical needs and provide scalable solutions not only for home healthcare but also other applications driven by vital signs. In addition, three applications platformed on this architecture are described.

	We have developed second-generation prototypes of the Internet Chair, a novel internet appliance. The ??rst generation explored using the chair as an input device; the prototype described here, is a pivot (swivel, rotating) chair deployed as an output device, a rotary motion-platform information appliance. Its haptic display modality is yaw, dynamically synchronized with wireless visual displays and spatial audio in a rotation-invariant virtual space. In groupware situations, like teleconferencing, chat spaces, or multi-playergaming, such orientation is also used to twist iconic representations of a seated user, avatarsin a virtual world, enabling social situation awareness.Using its audio displaymodality, transaural speakers (without crosstalk), "near-phones" embedded in the seatheadrest, the system can present unencumbered binaural sound with soundscape stabilization for multichannel sound image localization. As a haptic output modality, chairs with servomotors render kinesthetic and proprioceptive cues, direct the attention of a seated subject insistence/forcefulness), orienting seated users like a "dark ride" amusement park attraction or under active user control, local and/or distributed. The manifesting as personal lbe (location-based entertainment) can be used in both stand-alone and networked applications. We have developed a multiplayer game that exploits some unique features of our networked rotary motion-platform, loosely resembling a disk/disc access driver, in which "spin-dled" players race to acquire circularly arrayed dynamically arriving targets.

	This article describes researchonan interface to collaborative virtual environments via mobile phones which can remotely control signaling devices along a suggested route across the internet. A mobile interface, designed for use in a distributed virtual environment, was developed to find the path from a start to a goal, display the path, and move icons dynamically using the results. Programmed with J2ME (Java 2, micro edition), the dynamic map application runs on an i-appli mobile phone. The interface can be used to control avatars in a teleconference or chatspace.Theinterface is integrated with other cve (collaborative virtual environments) clients via a servent (server/client hybrid) http<->tcp/ip gateway. Through the servent, the mobile phone interoperates with a heterogeneous groupware suite to interact with other clients, including a networked device called a lan-tap, which can operate lights and sounds. The way-finding application integrated with the distributed signaling functionality provides a mobile interface to animated direction-suggesting cues embedded in the natural environment. Keywords: mobile computing, multimedia signaling, teleoperation, ubiquitous computing, way-finding.

Structural Representation of Perceptual Similarity and Multilingual Verbal Attributes; Deriving a Common Perceptual Space for Perception of American English Vowels by Englishth and Japanese Native Speakers. In Proc. ICA: 18 Int. Congress on Acoustics, Kyoto, April 2004.
	A common perceptual space for 10 American English vowel sounds was derived for two groups o listeners| a group of native speaker of English and group of native speakers of Japanese. The stimuli used were ten vowel sounds synthesized using the often-utilized forman frequency values published by Peterson and Barney in 1952. Subsets of these two groups made rating on 12 bipolar adjective scales for the same set of sounds, each of the two groups using anchoring adjectives takenfrom their native language.Although there was no evidence of any difference between the twogroupsin their indscal-derived perceptual dimensions for these vowel sounds, the adjectives were used differently in describing those same perceptual dimensions by the two groups. The results of semantic differential analysis (sda) support the conclusion that the two groups' ratings on 12 bipolar adjective scales related somewhat differently to the dimensions of their shared perceptual space. This paper discuss examines methods from psychological science that are typically used to fund significant multi dimensional differences that exist between those stimulus samples. Examples are given of experiments using naive subjects who make both dissimilarity ratings and direct attribute ratings, and are also required to select which stimuli are preferred with respect to particular parameters such as naturalness, suitability, or pleasantness.
