Feature: Telepresence: A Technology Transcending Time and Space|
HIROSE Michitaka and MINATO Chihiro
Technology Approaching Humanity
HM: The GPS systems which I mentioned earlier used to costin the 10 millions yen (roughly six figures US$). And today they are available for a few hundred dollars. The CABIN system which you experienced earlier is still a laboratory research tool, and as such, extraordinarily expensive, but I'm sure that their prices will come down until the point when one day, all of a sudden, they'll become ordinary household appliances. Seems like that sort of thing is happening all of the time. (laughs) Only a few years ago just when you'd have thought that voice recognition programs were a completely inaccessible technology, and now you can pick one up for a few hundred dollars.
MC: The problem of how to treat approximate values....
HM: Yes. Computers continue to miniaturize, eventually becoming something like glasses, where each person would have one prescribed just for themselves. I'm sure that they will soon become "personal computers" in an entirely new sense of the word. In fact, we're already
seeing the emergence of wearable computers.
MC: Another interesting technology in this sense is ultra high-Magnetic 3-D position Sensor (Long Range version) (from What Is Virtual Reality, Diamond-sha) resolution photography, which can--even from a satellite orbit of 800 kilometers--still photograph with enough precision to capture a human hand. It is still extraordinarily expensive, but in the near future will be used in civilian applications, such as precision
documentation in museums and the like. High-resolution reality.
HM: Such as in simulation?
MC: Yes, I think so. What was until now known to be simulation itself, yet in its increasing potential to be simulation and nothing more than simulation, still, at the same time, has the power to create reality which also needs to be considered. It seems that reality has really expanded to this point.
HM: Even we in the field of VR tend to consider VR as a form
of simulation. To use an earlier day's phrasing, simulation is a model of reality. The problem is when the model supercedes the reality, as can happen in our field. Many architects, for example, have been using VR-type simulations in developing their urban designs. They are testing
out their ideas in cyberspace, and developing spatial concepts appropriate for cyberspace. Of course this is still taking place within simulation technologies, but within the space of their discussions that city exists in
their consciousness. What's interesting is what happens then.
MC: If I'm not mistaken, the concept of simulation comes from associations of the body and its double or shadow. And "image"as it is understood in the west is a two-dimensional rendering of the actual figure. In other words, the shadow of the original. As a subsidiary existence its status is of a lower nature. First you have the authentic reality, and then its image naturally follows. Or in the case of building a city, the traditional process is to project a number of these shadows upon the potential phenomenon. What you describe is a shift in this very thought process.
HM: I would describe it as the virtualization of actual space. The urban environment traditionally constituted of architecture or built objects. But when computers and network technologies enter into the picture, the urban space itself ceases to be developed as a thing, and begins to be developed as a condition. When things have come this far, what is important is not whether some element was simulation or not, because it is all the same at that point. In this sense, it is as though they begin with beta versions of the city, which, through a gradual process of development, produces something which is the sum of real elements in the planning process.
MC: That's why we don't know what comes next with simulative forms of reality. It could be that we've only attached the real to the project as a kind of final process step. (laughs)
HM: Even if we consider simulation as a lower class of existence, there are things with factual meaning and therein reality which, if recognized, then provides a viable intellectual value--then it is only normal that we should accept this as the emergence of a separate dimension. We have to speak of this dimension in cultural terms, because it speaks to what human beings are looking to. It could be that the youth of today are not at all as fixated on reality as we are. They're perfectly happy with the coarse imagery of video games. The sad thing is that we were brought up on TV. We want things to look a little more real. I think that there is a huge cultural gap there.
MC: Probably so. Reality and telepresence both come down to issues of the ability to imagine, if you ask me. Thank you very much for taking the time today to speak with me.
