Dear TGardeners, So, we need better wireless, tracking, body-borne sensing... Who can do what? I'd like to track down a solution to only one of those problems. Who can follow up on the wireless, beaming data (preferably by 802.11?) ? Maybe the "mote" ? (Gatech has a bunch of them) On tracking -- here's a somewhat comprehensive survey: Rolland, J.P., Davis, L. D., and Y. Baillot, "A survey of tracking technology for virtual environments", in Augmented Reality and Wearable Computers. Ed. Barfield and Caudell (Mahwah, NJ), (2000) Don has a radio system that'lll track finely 2" spatial, 4 ms or 17 ms spatial resolution. Cost $15K to $3K, tho. Shall we buy a solution? I may form a consortium to share gear here in N. Am (and maybe V2) for tgardens -- tg, tx ? whisper ? Such devices could be worn like jewelry, on wrists, ankles, around neck, ... pocketed (not so good since locations would vary too much from body to body), ... Underlining Joel and nodding with Nik's observation, causality and connection are constrained by system latency. In addition to reducing local latencies, we can also look to musical phrasing and temporal textures. Xin Wei |
