we had some conversation in the comments of previous blog posts (for example here) and in several emails about what might happen in seoul.

in the following, i’m trying to bring together the relevant parts. please feel free to edit the posts, delete or correct anything.

1) information from roy

A horizontal screen, in the form of a large table-top approx 170 cm x 170cm will be needed to be built. The projection can be either overhead (requiring low ambient light) or back-projection under the table-top screen. . The project requires a very good graphics card so that all of the shaders of Second Life can be enabled. I am advised that the graphics cards which work best with Second Life are the higher end products of Nvidia Geforce. We’ll need high RAM (4MB or above) and a high screen resolution. Processor speed is also important. The size of the hard disk is not a big issue given that SL will cache only 500MB as a default. A good sound card and a good sound system to go with it are crucial since sound is a very important immersive factor in a 3D world.
To summarise:
Graphics Card: NVIDIA GeForce 9600 or higher
Processor: 2.4 Ghz – 3 Mb or higher (Dual Core or better Quad Core)
RAM: 4 MB or higher (this should be 4 GB, i guess)
Screen Resolution: 1600 x 1200 or as high as we can possibly get it, 1920 x 1200 would be even better
Sound: Yes
The project will require a projector capable of translating a high screen resolution like 1600 x 1200 or even 1920
x1200 into the display settings

They then asked me to know which projector etc we recommend . and any other info about how the project would be used and interacted with, either remotely or by visitor interaction. Mike Phillips is getting in touch with them about the projection tech.

2) question from roy

what naively I haven’t quite grasped is how visitors to the installation – the screen — will interact or not with what is on it, from what point of view? from what controlling interface?
Is passive public viewing possible? Like, just being in the room and seeing stuff happening on screen.
If , at any given time, no one is actively online, what is the status of stuff on the screen? Simply put (and probably childishly put) do we need a kind of ‘public avatar’ through which the general visitor views the SL text behaviours?

2) response from selavy

your question hits one of the weak points of exhibiting work using a virtual world.

it is possible to have passive public viewing, if we use one avatar as “eye”, which is moving through the installation. the avatar would be logged in in the morning, and logged out when the museum closes.
while this would at first glance look like a video recording, an attentive visitor could easily recognize that it is in fact a real-time window into the virtual world, since there’s no loop, no repetition, and the real-world visitors could even observe virtual visitors.

passive viewing evidently has the disadvantage that true interaction, the core of virtual-world experience, is not possible. some programming would be required to make such an passive viewing an interesting experience.

it’s also possible to enable visitors to actively experience the work, if we have, as you suggested, a “public avatar” operated by visitors. this would be the genuine and preferred way of experiencing the work (keywords: presence, immersion, etc.).

however, to my knowledge there is currently no simplified GUI for Second Life, which would work reliably in a exhibition setting. such simplified user interface would allow visitors to control the public avatar for movement, i.e., walking and flying, and let them touch objects to activate them or to sit down on them, but not more. since the current user interface is open source, it would be possible to create such an interface, which would be a door for opening Second Life to other shows, but not in the short time left.

3) information from max

* visitors can use their “smart phone” to inerakt infront of the projection
* visitors (if they know how to use sl) can go to the sim and play

if there is mouse and keybord the users can go everywhere in sl with the avatar. the visitors will be overstrained with to much interaction.

one possibility would be the space navigator i did that at the chris marker exhibition in belgium. http://www.3dconnexion.eu/products/spacenavigator.html
there are just 2 buttons on it and the movement, one sets this “joystick” to the camera mode and the visitor can cruise around in the sim, the other button sets it back to the view of the avatar (where he sits). at this point we can use this “video player”, programmed sl camera-avatar-movement which Selavy has done ore the one my students made.

3) selavy’s question

we’ve talked about letting people enter text before, elif argued that it would lead to spam,and we dropped that.
now the question is: do we want some kind of interaction with the text? or is the text something that automatically builds up and the visitors cannot do anything?
