- On two occasions this year, once in May and again in July, I
- was privileged to travel to Japan to study virtual worlds technology
- in that nation. Each trip was valuable in its own way, the first as a
- general introduction to Japan and in the field of electronics, the
- leading Japanese computer firm, Fujitsu; and the second to validate
- lessons learned on the first, including an appreciation of the
- situation in which Japan's leading virtual-worlds researchers find
- themselves. First, however, I would like to make some general
- comments.
-
- * * *
-
- Without question, Japan is a culture unique unto itself that
- (like all cultures) is best experienced from within. The tour books
- are helpful, and it is wise to read up before visiting, but somewhere
- along the line all explanations fail. The surface manifestations of
- Japanese culture -- the trains that invariably run on time and stop
- precisely, within inches of the indicated platform; the uniformity of
- clothing among urban workers; and the unfailing politeness of
- Japanese people in all situations -- soon give way to a deeper
- appreciation of what it means to be Japanese. I would not say that
- conformity is the most striking Japanese characteristic, though
- even the Japanese like to joke about how fads sweep the nation.
- More essential to "being Japanese" is a sensitivity to the
- appropriateness of behavior in different settings, and a concern for
- the well-being of individuals among the collectivity.
-
- I do not want to overdo this to the point of blindness or
- sentimentality. Truly, there are divisions between the wealthy and
- the less well-off (one seldom sees the poor, though they are
- present); some people walk while others ride in company cars; and
- the styles of food indulged in by cosmopolitan Japanese are many
- more than those enjoyed by the salt of the earth. But the pride that
- Japanese feel in being Japanese is impossible to miss and the care
- to do what is right, according to custom (even to the short-order
- cook who takes time preparing the traditional bento lunches or the
- department-store clerk wrapping a purchase), is pronounced. One
- story will suffice to sum up the essence of Japanese life:
-
- One day, in a busy train station downtown, our guide was
- purchasing train tickets for Tom Furness and me, in order
- to hasten our on-time arrival at an important appointment.
- In his haste, he bobbled the handful of change given to him by
- the ticket machine, spilling coins everywhere. Suddenly,
- everyone within hearing of the falling change stopped in
- his or her place, spotted a rolling coin, chased it down,
- carried it back to our guide, and place it in his palm, bowing
- as he or she did so. No words were exchanged; none were
- necessary. Anything less would have been impolite.
-
- One might also mention that 80 percent of private automobiles
- are painted white, the color of purity, not out of any metaphysical
- awareness but simply because cars painted white are easier to
- resell. On the other hand, taxis, destined for hard use and early
- retirement (the only used cars on the road are heirlooms), are
- garishly colored on the outside and linen-lined on the inside.
-
- Above all, as my Japanese friends remind me today, the
- appropriate word for all actions is -- patience. Things get done
- when it is right for them.
-
- Having set the tone for our visit -- we, the innocent gaijin
- (foreigners), for whom all gaffs are permitted but two (soiling the
- water in the soaking tub and wearing shoes on the tatami mats --
- now embark on a short tour of Japan's virtual worlds community....

-
- May, Fujitsu Research Institute. Tom Furness, director of the
- HIT Lab, and I made our first trip to Japan in the still springlike but
- warming atmosphere of May. We were hosted by the Fujitsu
- Research Institute's Dr. Masahiro Kawahata. The Fujitsu Research
- Institute, a relatively new unit of Fujitsu Electronics, is considered
- to be Fujitsu's think-tank, a place where long-range planning for the
- entire corporation takes place. Dr. Kawahata, a former IBM engineer
- and director of the groundbreaking Hi-OVIS Japanese cable
- television experiment, is a managing director of FRI and one of those
- Japanese among whom groups congeal to undertake pioneering
- efforts.
-
- We were under two constraints on this trip. First, as guests of
- FRI, it would have been terribly impolite for Tom and me to visit
- with Fujitsu's competitors. Although we in other lands often see the
- Japanese society as monolithic, in fact there is fierce competition
- among Japanese corporations increasingly beyond the control of
- MITI, the once all-powerful Ministry of International Trade and
- Industry, and other mediating institutions. One may visit a company,
- its subsidiaries, and (with permission) the "family of companies"
- friendly to a firm, without creating too much fuss. (These
- "families" are different from the keiretsu, or large associations of
- commonly owned companies, for sometimes there is competition
- even within keiretsu and closeness among firms from different
- keiretsu doing business across keiretsu boundaries.) As a guest of a
- firm, however, one does not spend time with competitors ... and
- learning the terrain of business takes considerable time.
-
- So Tom and I stayed close to Fujitsu. However, we were
- enabled to visit with NTT, the national telephone company; and with
- MITI's various laboratories in Tsukuba Science City, as these are
- both customers and collaborators with Fujitsu.
-
- Our second constraint was that we not divulge confidences
- shared with us by Fujitsu, particularly concerning its activities in
- the area of virtual worlds. So my report on this first trip is
- necessarily sparse.
-
- In fact, our days were spent largely in the company of Dr.
- Kawahata and his associate, Mr. Masaru Hosoda, who accompanied us
- on all of our field trips. We never felt, however, that anyone was
- withholding information from us or being less than candid in
- describing their research or referring us to others. On returning to
- the U.S., our initial reports regarding Japanese accomplishments
- were considered with some skepticism, our inquisitors almost
- always wondering what was held back from us. I believe I can
- honestly say that we were as well-informed about current activity
- as we would be in an analogous university setting. About our hosts'
- future plans, however, I can say very little, as we were not made
- privy to them.
-
- Our tour of Fujitsu was almost overwhelming in terms of the
- many telecommunications and computer technology teams we met.
- In addition to meeting with FRI researchers, we also met with
- researchers from Fujitsu Laboratories, from which FRI was spun out,
- and with operating company scientists and engineers. A surprising
- number of these individuals were women, no less than we might see
- in an American engineering company, although I cannot speak to the
- respective roles of the researchers within these organizations. Only
- one woman researcher was the primary investigator of a research
- project, but again this is not much different from affairs in the U.S.
-
- Most of those with whom we spoke at Fujitsu were not
- involved directly in virtual-worlds research, but instead were
- working with "conventional" telecommunications and computer
- technologies. I add the parentheses to indicate that the work is on
- developments of technology that are cutting-edge in these fields.
- None was unrecognizable, but clearly Fujitsu has ambitions beyond
- its current market position.
-
- The two most interesting laboratories we visited at Fujitsu
- were those of Dr. Shuzo Morita and his colleague, Mr. Masanori
- Kakamoto, who head up Fujitsu Laboratories' well-publicized effort
- to develop virtual-worlds technology; and that of Mr. Kazutomo
- Fukuda and Osamu Imoto, who direct Fujitsu's HABITAT Project.
-
- Dr. Morita and Mr. Kakamoto have used the standard VPL
- technology, enhanced by the use of a neural network to instruct the
- DataGlove, to create an entrancing undersea world populated by
- friendly jellyfish and a menacing shark. One lures the jellyfish by
- means of a wave, Japanese-style (underhanded), and chases away the
- shark with a beam of light that emanates from the glove. The
- jellyfish give off cooing sounds not unlike the characters in a
- Japanese-produced children's cartoon. I was struck by the ad hoc
- presentation area in which we were shown this experiment, not too
- different from our own back at the HIT Lab. Dr. Morita's lab is
- striving toward a more standardized ensemble of equipment and
- greater comfort in their presentations. Also shown to us was the
- self-composing musical array put together by the woman engineer
- whom I mentioned earlier. This device "taught" itself to mimic and
- then expand upon Mozart's work.
-
- The HABITAT Project is an enhancement of the first Habitat
- designed for Commodore by Randy Farmer and purchased by Fujitsu,
- adapted to Japanese tastes, and now sold as a public telecommuni-
- cations service. For those who have not seen HABITAT, it is a sort
- of visual MUD, which a player, equipped with a Fujitsu FM Towns
- computer/CD-ROM player and modem, enters via the telephone lines.
- A player assumes identities, acquires trading tokens, and interacts
- with others who are similarly present in HABITAT at the time one
- calls. Several thousand Japanese currently use HABITAT, which has
- grown into many hundreds of "rooms," or separate environments.
- Tom and I were quick to note that the combination of virtual-worlds
- with HABITAT would make for a killer service, if the two could be
- made compatible. This had not escaped our Japanese hosts, but the
- task of elaborating HABITAT has been made difficult by the sheer
- immensity of upgrading and maintaining the current system. (We
- also suggested a build-it-yourself facility, something which had
- escaped our hosts' attention.) HABITAT is commercial, but it pro-
- bably still does not cover its costs; so it must be seen as primarily
- experimental at this stage.

-
- Our other memorable visits on this first trip were to NTT and
- the MITI labs in Tsukuba. Regrettably, we did not get to see the ATR
- Laboratory, a real leading-edge spinoff of NTT, in Kyoto.
-
- NTT is the largest company in Japan, capitalized at many, many
- billions of dollars. Until recently, it was a monopoly, supplying
- local telephone service without competition throughout Japan.
- (Long-distance service is provided by KDD, still a monopoly, I
- believe.) Today, as a result of liberalization of the economy, NTT
- now faces competition on many fronts -- transmission, equipment,
- and so forth -- but still remains dominant across the board.
- However, as a result of the privatization of NTT, its budget is no
- longer certain. In fact, in the last year, NTT has suffered severe
- budget cuts, limiting its ability to fund basic R&D.
-
- Nevertheless, one cannot underestimate the variety of
- experiments taking place at NTT's Human Interface Laboratories, in
- Kanagawa, under the direction of Dr. Takahiko Kamae and Mr. Takaya
- Endo. Work on various interface variants is an ongoing preoccupation
- of these Laboratories, in both visual (Drs. Kobayashi, Suenaga and
- Ishii, and Mr. Hiraiwa) and acoustic environments (Drs. Furui and
- Koizumi, the latter from another NTT lab), and general human factors
- research (Mr. Suzuki) . However, we saw no work that could be
- called "virtual worlds" research per se, although with time some of
- the more interesting prototypes of facial recognition and groupwork
- technologies could find application in a virtual world. The emphasis
- on traditional teleconferencing, which I find so annoying among
- American telephone companies as if it were the end-all and be-all of
- telephony, was also pronounced at NTT, leaving me to wonder if the
- Japanese telecommunication vision of the future is so different
- from our own. (However, I do recommend a viewing of "Birthday," a
- short NTT videotape, which is perhaps the warmest evocation of the
- information age to date.)

-
- Tsukuba Science City, a planned development intended to bring
- together researchers and developers from government laboratories
- and private firms, is something of a disappointment. It is not an
- unattractive place, but the spirit of technical excitement one finds
- at the most active (and admittedly, chaotically so) industrial parks
- in North America was not present. Instead, we found within the
- various laboratories scientists of a more academic bent who were
- struggling to bring forth Big Ideas with relatively small resources.
- This is not to say that the MITI labs are unproductive; far from it.
- Much interesting research is taking place there, and it is from the
- MITI laboratories -- primarily the Mechanical Engineering Laboratory
- (MEL) and the Electro-Technical Laboratory (ETL) -- that the
- pioneering telerobotics experiments of Drs. Tachi and Maeda, the
- tactile-field work of Mssrs. Fukui and Kotoku, and the successful
- optical networks experiments of my close friend, Dr. Ishihara, have
- sprung. With larger budgets and closer intercourse with industry,
- however, these scientists could do much more. In fact, Dr. Tachi,
- whose telepresence gear permits one to "enter" into the body of a
- video and virtual world-equipped robot body, recently left for Tokyo
- University, presumably in pursuit of that more intimate relationship
- with commerce. (His work is being continued at MEL by Dr. Maeda.)
-
- At Tsukuba University, a technical school close by the MITI
- laboratories, we met Dr. Hiroo Iwata, who with his students is
- conducting research in tactile environments. Dr. Iwata has tricked
- up two fine demonstrations, one a ramp on which one "walks" up
- stairs using roller-equipped shoes wired to sensometers; and an
- exoskeleton not unlike the Exos, which permits one to pick up and
- toss (not very far, however) a virtual ball. Dr. Iwata is one of the
- four Japanese scientists who were featured at the Nikkei
- Symposium on Artificial Worlds and Tele-Existence held in July, on
- which I next report.
-

-
- Finally, I should mention the work being done by my dear friend
- Mr. Koji Sato and his protegee, Mr. Masao Kunishige, for the
- Kanagawa Prefectural Government. Kanagawa, the home of
- Yokohama, occupies a position second only to Tokyo (which it
- borders) as an economic center -- a situation it is trying to remedy
- by attracting more industry to itself. Mr. Kunishige now presides
- over Kanagawa Science Park, a large integrated industrial
- development to which many high-tech firms are moving. Mr. Sato is
- a researcher in industrial policy for Kanagawa and, lately, a student
- of virtual worlds technology, as well as an instructor at Chiba
- Institute of Technology, a prominent technical university in
- Kanagawa.

-
- I have left out the wonderful time spent in restaurants with
- colleagues, and the adventures that novice travellers always have in
- strange places (easier to solve here, with friendly people, than in
- many other locales, however), in order to keep this report reasonably
- short. One week in Japan was all that Tom and I could afford, and we
- were completely saturated by the time we left the crowded Narita
- International Airport. I must not fail to mention, however, the
- rousing speech given by Dr. Kawahata to his researchers assembled
- from all of Fujitsu's relevant divisions. "For too long," he observed,
- "we in Japan have been relying on research done by others, improving
- on it but not generating it. Now, it's time for us to do our part, to
- add to the basic knowledge regarding artificial reality and to make
- *our* a contribution for human well-being." He was loudly
- applauded....
