Computer Art Laboratory

Michael Cohen
Professor

Most of the courses taken by engineers and computer science students emphasize scientific discipline and the accumulation of "truth." The Computer Arts Lab. activities includes such technically objective factors, but also encourages original expression, subjectively motivated by aesthetics rather than "correctness," sometimes "putting the art before the course!" Unlike many other labs' activities that try to converge on a "right answer" sharable by everyone else, artistic disciplines encourage originality, in which the best answer is one that is like no one else's!

The Computer Arts Lab., through its resident Spatial Media Group,¹ is researching projects including practical and creative applications of virtual reality and mixed (augmented, enhanced, hybrid, mediated) reality and virtuality; panoramic interfaces and spatially-immersive displays (especially stereotelephonics, spatial sound, and stereography); wearable and mobile applications, computing, and interfaces; and networked multimedia, with related interests in cve (collaborative virtual environments), groupware and cscw (computer-supported collaborative work); hypermedia; digital typography and electronic publishing; force-feedback displays; telecommunication semiotics (models of teleconferencing selection functions); information furniture; way-finding and navigation; entertainment computing; ubicomp (ubiquitous computing), calm (ambient), and pervasive technology. We are particularly interested in narrowcasting commands, conference selection functions for adjusting groupware situations in which users have multiple presence, virtually existing in more than one space simultaneously. We explore realtime interactive multimedia interfaces-- auditory, visual, haptic, and multimodal:

Auditory We are exploring interfaces for multichannel sound, including stereo, quadraphonic, and nearphones (mounted on our rotary motion platform) two separate speaker array systems in the University-Business Innovation Center 3d Theater,² and an octophonic system in our lab. Working with Dr. Durand Begault of NASA, we deployed online courseware, "Sonic,"³ organizing an introduction to desktop audio and presenting many sound samples. We use these contents in the "Audio Interfaces," graduate school course,⁴ which is a prerequisite for "Spatial Hearing and Virtual 3D Sound,"⁵ taught jointly with Prof. Jie Huang in the Human Interface Lab.

With Profs. Robert Fujii and Satoshi Nishimura, we host a Computer Music Studio, featuring about fifteen computer music workstations-- each comprising a personal computer (Windows and Macs) with sequencing software and a keyboard synthesizer-- plus assorted amplifiers, racks, mixers, and effects processors. Ongoing student projects explore dynamic microtuning systems, quadraphonic spatialization of tetraphonic bass guitar strings, and control of narrowcasting using sip (Session Initiation Protocol).

We annually conduct a Student Cooperative Class Project.⁶ In the past we have sponsored sccps on Digital Compositing (using Photoshop and the Gimp⁷ ), but recently the sccp has been focused on Computer Music,⁸ studying basic music theory and using a midi sequencer⁹ to compose and perform student-authored songs. This sccp segues into a graduate level computer music course.¹⁰

Visual We promote creative applications of scientific visualization, encouraging the use of Mathematica¹¹ and stereoscopy,¹² including chromastereoscopy¹³ (3d images with depth layers cued by color). We enjoy exploiting the unique large-format immersive stereographic display in the UBIC 3d Theater. Some group members are using visual input techniques through a web cam to sense user mood, for kansei interpretation, or for control of narrowcasting chatspace interfaces. We are also exploring creative applications of panoramic imaging and object movies.¹⁴

Haptic We are also exploring the use of haptic interfaces, including force-display joysticks and a rotary motion platform (the "Sc haire [for `shared chair'] Internet Chair"). We also conduct annual Creative Factory Seminars. Past cfss explored advanced audio interfaces and panoramic imaging, but in recent years, in conjunction with Prof. Rentaro Yoshioka of the Distributed and Parallel Processing Lab.,

We conduct annual Creative Factory Seminars. Past cfss explored advanced audio interfaces, panoramic imaging, and haptic modeling. This year, in conjunction with the Distributed and Parallel Processing Lab., we conducted a workshop on Haptic Modeling and 3d Printing, using force-feedback CAD workstations¹⁵ to make models that were then rapid prototyped (as stereolithograms) with the dppl's personal fabricator,¹⁶ closing the "idea (stored in brain neurons) - information (stored as bits) - matter (atoms)" pathway.

Multimodal Using such multimodal interfaces, our students have crafted driving simulators, location-based games featuring the rotary motion platform,¹⁷ synaesthetic (cross-sensory modality) visual and haptic music players (rendering songs as light shows<18> or dancing chairs¹⁹ ). Using the aforementioned visual sensing technique, narrowcasting postures can be recognized, and used to control distributed chatspaces or virtual concerts. A recent student project deployed a microphone vector to track a moving sound source, using its network interface to trigger internet appliances (like lights that follow the source). We are also developing a driving simulator using collision-detection modulation of the force-feedback steering wheel and the rotary motion platform. The most recent version of the project features a dual-steering (front and back) fire truck, racing through a 3d model of our campus to reach a fire, piloted by two drivers, and featuring spatial sound effects.

We are also exploring mobile (nomadic, portable) computing, working in conjunction with university spin-offs The Designium,²⁰ Eyes,²¹ and GClue.²² Such keitai - based interfaces can be used to control internet appliances, panoramic imaging, spatial sound, or motion platforms. An exciting project combines spatial sound with way-nding, using gps tracking, the Segway personal transporter, and directional transfer functions.

Other activities:

We host an annual symposium, the Int. Symposium on Spatial Media,²³ inviting experts to share their knowledge and passion regarding such themes as “Spatial Sound and Spatial Telepresence” (’01), “Magic in Math and Music” (’02), “Advanced Multimedia and Virtual Reality” (’03), “Spatial Sound” (’04), “Hearing and Sound Installations” (’05), “Sound, Audio, and Music” (’06), “Interactive Media, Security, and Stereography” (’06), and “Music XML and the Structure of Swing, Understanding Color Media, Media Grid, and Visualization Tools” (’07).

Our lab sponsors several student performance circles, including the Yasakoi Dance Circle,²⁴ Disco Mix Club, and Project Mermaid. We also sponsor a couple of other student circles, the Dual Boot (Ultimate Frisbee) Flying Disc Club and the Furiten Mah Jongg Circle.

Through the research & development, the deployment & integration, of stereographic, spatial sound, and haptic applications, we nurture scientific and artistic interest in advanced computer-human and human-human communication. Our ultimate domain is the exploration of interfaces and artifacts that are literally sensational.

	To support multiperspective and stereographic image display systems intended for multiuser applications, we have developed and integrated two multiuser multiperspective stereographic "browsers," featuring ibr-generated egocentric and cg exocentric perspectives. The rst one described uses Apple's QuickTimeVR technology and the Java programming language together with the support of the `QuickTime for Java' application programming interface (api). This unique qtvr browser allows coordinated display of multiple views of a virtual environment,limited only by the size and number of monitors or projectors assembled around or among users (for panoramas or turnoramas) in various viewing locations. Named "VR4U2C" (`virtual reality for you to see'), the browser also provides a novel solution to limitations associated with interactive stereographic display of qtvr imagery. A multinode implementation providing stereographic qtvr (which we dub `sqtvr') enables display of pairs of images exhibiting binocular parallax, and the stereoscopic depth percept that results is enhanced by motion parallax inherent in displacement of the viewpoint through a displayed 3d space coupled with rotation of the view through a complete 360^° horizontal panorama. Our navigable approach to sqtvr allows proper occlusion/disocclusion as the virtual standpoint shifts, as well as natural looming of closer objects compared to more distant ones. We have integrated this stereographic panoramic browsing client with a sibling client, named "Just Look at Yourself!", which is based on Java3d and allows realtime exocentric visualization of the dollying and viewpoint adjustment, and juxtaposition and combination of stereographic cg (computer graphic) andibr (image-based rendering) displays. The Java3d application visualizes and emulates VR4U2C, integrating cylinders wrapped around the stereo standpoints and dynamically texture-mapped with a set of panoramic scenes into a 3d cg model of the same space as that captured by the set of panoramic scenes. The transparency of the 3d cg space and the photorealistic stereographic panoramic scene, as well as the size of the `stereo goggles' upon which it is texture-mapped, can be adjusted at runtime to understand the relationship of the spaces. Keywords: collaborative virtual environments (cves), image-based rendering (ibr), binocular parallax, stereographic panoramic navigation.

	This article proposes a new focus of research for multimedia conferencing systems which allows a participant to exibly select another participant or a group for media transmission. For example, in a traditional conference system, participants' voices might by default be shared with all others, but one might want to select a subset of the conference members to send his/her media to or receive media from. We review the concept of narrowcasting, a model for limiting such information streams in a multimedia conference, and describe a design to use existing standard protocols (SIP and SDP) for controlling ne-grained narrowcasting sessions.

	We address the problem of visualizing microtuned scales and chords such that each representation is unique and therefore distinguishable. Using colors to represent the different pitches, we aim to capture aspects from the musical scale impossible to represent with numerical ratios. Inspired by the neurological phenomenon known as synæsthesia, we built a system to reproduce microtuned midi sequences aurally and visually. This system can be related to Castel's historic idea of the `Ocular Harpsichord.'

	Traditionally, Shepard tones are compared to the optical illusion given by the Penrose stairs. However, for such three-dimensional objects, the illusion is only achieved from certain points of view. By displacing the position of the viewer, it's possible to see the gaps between the extremes of the staircase. This artifact doesn't have an aural counterpart, as the concept of 'point of view' has no analog. To circumvent this problem, we use a Mbius strip which has a non-orientable topography with only one surface and one edge. One can think of the edge of the surface as the tonic of a scale, and points across the strip as notes in the scale. Due to the nature of this object, every point over the surface has two representations in the musical scale, making it impossible to play a single tone (with the exception of the unison). In our Java3D application, the position of the ball is sampled at regular intervals, and its distance from the edge is sent to a built-in synthesizer based on the Java Sound API. The user can navigate through the space or interact with the model by specifying the position sampling rate, the randomness of the path, the tonic of the scale, the color interpolator, etc.

	In traditional conferencing systems, participants' voices might by default be shared with all others. However a VOIP user might want to select a subset of session members to selectively exchange media streams. In this article, we describe an implementation of narrowcasting, a model for limiting such information streams in a multimedia conferences, as a class of policies, prototyping a system using existing standard Session Initiation Protocol (SIP) methods for controlling negrained narrowcasting sessions.

	For an increasing amount of people (especially young people), the mobile phone, and not the computer is becoming their main media device and portal to the virtual world. Mobile phones have become a ubiquitous technology and for many people an important tool for communication and information access. Mobile telephony offers an interesting platform for building multipresence-enabled applications that utilize the phone as a social or commercial assistant. The main objective of this research is to develop multipresence-enabled audio windowing systems for visualization, attention, and privacy awareness of narrowcasting (selection) functions in collaborative virtual environments (CVEs) for mobile devices such as 3rd- and 4th-generation mobile phones. Mobile audio windowing system enhances auditory information on mobile phones and encourages modernization of office- and mobile-based conferencing.

	In analogy to broad-, multi-, and any-casting, narrowcasting is a technique for limiting and focusing information streams. For modern groupware situations like teleconferences, in which everyone can have presence across the global network, users want to shift and distributeattention (apathy) and accessibility/availability/exposure (privacy), and narrowcasting organizes source and sink exclusion and inclusion filters mute, select, deafen, and attend. To realize an elegant predicate calculus notation formalizing such attributes using the logic programming features of Mathematica, the existential quantiers were reimplemented to reference a list-expressed finite domain, working-around the non-trivial finite domain of their application, avatars in a virtual-reality style user interface. Keywords: Predicate Calculus, Existential Quantiers, Narrowcasting.

IEEE Wkshps. on Enabling Technologies: Infrastructures for Collaborative Enterprises, pages 424-429, Paris, June 2007.
	We describe the integration of two pairs of force displays comprising a force-feedback wheel (ffbw) and the ^S _c ha_ir^e (`Share Chair'), a rotary motion platform, in a dualdriver networked driving simulator which can share a virtual space using cve (collaborative virtual environment) groupware. We have developed a double-driver (long ladder-style) fire-truck simulation with a tiller (rear steering), driven via an integrated pair of networked driving simulator stations. The dual-driver system is useful to turn narrow corners rapidly and smoothly in case of (simulated) emergencies. Its ffbw steering wheels display simple collision force to drivers when the vehicle collides with walls or other vehicles. The technique of feeding back the effect employs programs using C++ and DirectInput,escaping to an execution file called ForceManager from the networked driving simulator, which is implemented with Java3d. The effect pattern is changed by arguments to ForceManager. The ^S _c ha_ir^e is rotated with a servomotor, the rotation angle controlled via internet through the cve.

	In this survey, we review current mobile phone technology and market in Japan in various elds. We also consider next-generation mobile phone infrastructure and innovative services, describing how future mobile infrastructure works by introducing some cutting-edge technology differing from the current mobile infrastructure. We explain why new services such as CGM (Communication Generated Market) content and media type content will become available in the future mobile network. New services are based upon the advanced infrastructure built-into next generation mobile phones. Because of advancement of hardware specifications and new technology, features of mobile phone terminals will evolve drastically from 2007 through 2010, and our daily lives will also be altered accordingly.

	We are exploring the experience of a QTVR "object movie" by contrasting the sensation when such contents are browsed with and without synchronized rotary chair motion and panning sound. The haptic sensation induced by the vestibular system and the binaural auditory stimulation can potentially disambiguate the apparent mode of a virtual object examinationeither "turnorama," in which the subject is xed but the object rotates, or "spin-around," in which the object is fixed but the subject rotates and revolves in orbit around it.
