SL Web

Object touched, generates hidden

chat message containing Node ID

to SL Controller

Controller relays Node ID to web-based

player

Player looks up Node ID in exercise and

gets response

Player builds web page with response

for display, and sends data packet

into SL with response

Controller displays web page from URL, sends

response data on hidden chat channel to object, and chats any

text response on public chat

Object, if instructed, displays any text

response, changes any internal state,

and reflects in loc/appearance
