MurkSee
sonar VR for zero visibility scuba dives | |
A Plane goes into the sea off kapiti Is , New Zealand .
The flight recorders need to be recovered but weather has made the ocean bottom
impossible so the international rescue call goes out .
A team in Spain have a working prototype to test and Jettrans,
a x-military 2 seater fighter jet,
is
used to transfer a technician and gear to new zealand .
The technician has brought cables , software and underwater RF gear
which in conjunction with worldwide available computers builds the New VR sonar .
The outline for the system in the dive tender goes as follows
Three standard fish finders form a
net sensor which via interface cables connect to a PC . This machine processes and
packages the data off to a standard gaming machine .
(propriatory secret information has been kindly donated for this worthy cause)
The gaming machine processes the 3D maths and produces a 2D screen bitmap which is
sent to the last machine for 2 channel underwater tranmission .
Two pdas (one for each eye) siliconed to a dive mask receive the Rf via dedicated
receivers . The pdas are programmed simply buffer data to display because all
calculations have been done .
The Diver wears two hollow spheres on his head as a sonar vector for the enviroment .
Thankfully the test goes well the diver has a visual representation of the wreckage
and the recorders are retrieved catching problems with similar aircraft .
The successful technician transmitted the experiment data of the trial
to his eagly awaiting team , who were happy with the results .
More enhancements to MurkSee may include more sonor detail , depth, time data
and see-thru pdas so VR data is additive to vision .
If computers and equipement can be boarded and shrunk then the diver may carry
around MurkSee and therefore be boat independent .

Love the 'PDA's siliconed to a dive mask.' Very 'Red Green meets Jaques Cousteau.' Missing the duct tape, though. |
|
| |
Trying to decide if you were shooting for a story with this, or not. If you were, it's pretty awkward yet. |
|
| |
half-Synopsis: High resolution 3D sonar imaging device made with off the shelf consumer grade parts. ?. |
|
| |
Dunno if it'd work. For all I know it might be total nonsense, but I like the synthesis and the cheap factor. |
|
| |
Those PDA's seem a bit close to the diver's eyes to be viewed easily. |
|
| |
Keep your marmots and prairie chickens away from that eagly awaiting team! |
|
| |
I hate when a perfectly rational stepping stone logic path is shot down by one glaringly obvious painted polystrene rock that there is no way in hell you want to jump on . |
|
| |
A diver would get tied holding up his arm ,to see the VR , continuously throughout a dive . |
|
| |
Maybe a box structure could distance the Pdas from the divers mask allowing a respectable veiwing distance . |
|
| |
The hollow spheres will show up well on the sonar devices, giving an accurate position for the diver. erm...at least thats what I think they're for... |
|
| |
Dive depth would be limited by the crush depth of the spheres. Would the oxygen tank not show up quite well anyway? |
|
| |
Yes , Two spheres ( metal ? )one slightly bigger on head to show system head direction therefore change VR drawing . Tank no good because diver may be looking in wrong direction . |
|
| |
The ocean floor remains either pretty calm or as quite as a tomb depending on the depth. The weather above doesn't affect it except in v. shallow water. However, you could maybe sell this to those bog-snorkeling maniacs. |
|
| |
So the recovery divers on a network news item saying that they could only see
the distance to their dive watches were telling porkies . |
|
| |
OK. How deep are you talking about? Are these human divers or deep sea subs? If you're only talking about relatively shallow water, I'll hush my mouth. |
|
| |
Ah! Just detected "eyes" and "head" amongst scary technical words. Human then. Shallow water then. I'll shut up then. |
|
| |
[skipper] Thankyou , Idea sunk , not realistic with current sonar , diver interaction . No way around that one is there . |
|
| |
True , if , what is that word again, cetacean's have sonar that doesn't effect the enviroment , maybe the
idea can refloat . |
