Posted on 01/28/2009 10:29:13 AM PST by Domandred
Transportation officials in Texas are scrambling to prevent hackers from changing messages on digital road signs after one sign in Austin was altered to read, "Zombies Ahead."
Chris Lippincott, director of media relations for the Texas Department of Transportation, confirmed that a portable traffic sign at Lamar Boulevard and West 15th Street, near the University of Texas at Austin, was hacked into during the early hours of Jan. 19.
"It was clever, kind of cute, but not what it was intended for," said Lippincott, who saw the sign during his morning commute. "Those signs are deployed for a reason to improve traffic conditions, let folks know there's a road closure."
"It's sort of amusing, but not at all helpful," he told FOXNews.com.

I feel your pain.
I never wait for. I get my stuff together and go for it.
If it starts trilling and becomes indestructible, run.
I hope nobody will tell me about it.
Well, all packed and ready to go. 18 hours until we are scheduled to push back from the gate...
I do not envy you one scintilla.
It’s got its good and its bad. A whole lot easier just to stay home but I suspect that, like my late father-in-law, when it comes to an end I’m going to miss the travel.
I would suspect that the speed of communication will continue to advance remarkably, while the speed of travel will remain stagnant.
Eventually, virtual travel will be regarded as better and more efficient for most purposes.
Then real travel will be reserved purely for the sake of being able to say, “Yes, I was really there, and I saw it.”
For those of us who wear glasses, if seeing the world through a display device very like our glasses were a possibility, it would be very easy to fool us.
Then the next step is bringing the other senses along. Hearing is obvious and easy, but others are rather muted. Their physicality can be relatively easy to simulate.
Virtual travel will seem real enough when simulated reality gets enough bandwidth.
Something times for me it is better to have been there than going there.
It's happening already. Teleconferences are becoming more more common. Video-conferencing was tried at my site a few years ago, but apparently deemed inadequate because I don't see it being used any more. The "speed of travel" has been pretty well fixed for a long time, for those of us lacking Concorde budgets.
BUT all that said, all the "virtual meeting" arrangements to date are really deficient. I hate conducting Internet classes -- sure it costs much less than traveling, but you miss tons of feedback from the class. Sharing a powerpoint over the Internet doesn't give you visual feedback on their reception of the material, participants tend to be less ready to raise their (virtual) hand and ask a question...
When virtual travel gets to the point where surfing the web in the virtual class carries the same penalties as surfing it in a physical-presence class, then I might say it's arrived.

This happens, depending on the degree of immersion.
One of the reasons cell-phones are dangerous is because people lose track of where they are and what they are doing, blithely sauntering or driving into danger.
Just as a surfer might be blithely unaware of the circling Great White.
Better immersion techniques will exacerbate this problem. I recommend virtual reality chambers for recreation and for remote presence participation. In such a chamber, you would don a suit designed to feed you with information about the remote location and its occupants, and capture motions and facial expressions, as well as speech that you might produce.
In such a chamber, one might well “pace” back and forth while “presenting” information on a “stage”.
Or one could simply relax and observe while someone else does that, and look around at the other participants to see what their reactions are.
The easy configuration is to have everyone seated. Then you only need to put on a jacket with data-gloves, and a visor-type helmet or cap.
BTW I keep an obsolete computer around just to fly FU2 and ATF NATO with my obsolete visor type helmet (VFX1).
You build up a tolerance but until they solve the inner ear and focus distance problems VR headsets will remain pukey.
Just ain't gonna work for meetings. Covers too much face anyhow.
Lots of screens and cameras (1 face following camera plus 1 screen for each remote location for each participant) are all all ready available, but add up to $ and bandwidth.
For games/sims and demos of short to moderate duration VR's day will come.
I wouldn't want to get near a public VR chamber as you describe. They don't make disinfectant strong enough or electronics tough enough. Just ew. (How did they clean the Holodeck in Trek universe?)
A well-designed visor, which reflects to the wearer a different image to each eye, and tracks the head position as well as facial contortions, would provide everything needed for a virtual meeting.
That it covers a portion of the face would not be a problem, because the face will be reconstructed for the viewing of the other participants based upon a database of facial information as well as inputs from the visor.
It could easily show amusement, distraction, or confusion.
There is no reason to believe it would cause spatial distortion, especially if the chamber in which it is used is in relative darkness. The visor inputs would provide illumination for the virtual meeting, showing documents and charts in front of the participant, as well as the displayed faces and postures of other participants.
Some minor participant training might be required initially, but that’s why they put games on the computers to teach folks how to use a mouse.
They never let Wesley Crusher use it.
Why else would his only holodeck recording be labeled Crusher One?
Eh. Still not gonna fly, ‘Bob. Except for the few chrome domes, and MilSpec buzz cuts around the office, nobody’s down with the whole helmet thing, because the completely unenviable result is: “helmet hair”. One early morning Directors meeting would leave the entire upper echelon preening in the washroom mirrors for a full hour following, trying to fix their matted down hair.
And, try this grueling schedule on for size:
7:30am -— Executive Meeting
8:30am -— Hair Appt
10:00am -— Sales Meeting
11:00am -— Hair Appt
1:00pm -— Production Meeting
2:30pm -— Hair Appt
4:00pm -— Meet w/Accounting RE: Expense Reports
That’d go over like lead balloons in any economy.
That reminds me - I need a haircut.
Well, it's a bait bucket, but it's still cute.
"And, try this grueling schedule on for size:Wow! I had no idea you were working with the John Edwards staff!
7:30am - Executive Meeting
8:30am - Hair Appt
10:00am - Sales Meeting
11:00am - Hair Appt
1:00pm - Production Meeting
2:30pm - Hair Appt
4:00pm - Meet w/Accounting RE: Expense Reports"
I would be happy to work with anyone to design a "visor" which would be more acceptable. Perhaps you may picture a tiara instead, or a green eyeshade.
The principle is to have something which can monitor your facial expressions, the tilt and direction of your head, and present a screen for viewing to each eye. Seeing what has been done with miniaturizing microphones in the last forty years, I think we can do it.
I would have expected someone to object to wearing gloves as well. These devices are only for data capture or presentation. They should not intrude into one's awareness.
I’m sure your hair looks great, Bob!
My hair looks like a monk’s fashion statement.
When I had more of it, if I tried to let it grow long, I would start to look like Bozo, or maybe Carrot-top.
Gentlemen of mature years look best with short hair. Unless they’re Indians - then long, iron-gray braids are okay.
Morning, all. Up and leaving for the airport soon. Not sure when I’ll be back; Sunday at the latest, in a probability. Take care of yourselves...
I always like to start the day with a cat. How are you?

Well, get off the computer and ... you know ...
I have to go to Wal-mart.
I need to go to Walmart too...Wow did you see that Oprah is figuring out people actually shop and save at WALMART!!!!! Sheesh where has she been? LOL
We have huge over-the-road signs that the state of Illinois paid hundreds of thousands of dollars for. They just sit there, blank, 99% of the time.
Your tax dollars at work.
Have you ever used one?
The problem is that your inner ear and the ‘visual worlds’ orientation/motion don’t synch, you feel motion sick. Some people much worse then others.
Further, especially when using stereoscopic images, the fact that the eyes stay focused at a fixed distance while the parallax changes causes further discomfort.
Try one out and tell me it’s comfortable. Current models are much more expensive the my old one but the only improvements are in LCD quality and optics (both of which are really cheap on the old VFX1). Head tracking and frame rate were already ‘good enough’ (using a 1 gig CPU to run games designed for 200MHz).
Comfortable VR will require two improvements, one a breaktrough. Eye ball tracking, software focus object selection and zoom optics too keep the focal length appropriate is the less important, currently doable but uneconomic part. Tricking the inner ear is the part as yet impossible. I’m not all that comfortable with the prospect of putting current through my head to spoof motion, you first.
I practically live at Wal-mart. The cashiers ask me for advice about pregnancy and low-cost childrearing ;-).
I was at Wal-Mart this morning...
No one was there but me and the clerks and maybe two shoppers, so I read my list, got everything on it, and was out in 25 minutes....
I was all done with my errands before 9:00, and back home!!!
(I love it when it works this good!)
It was crowded at our Wal-mart at 1:00 pm. I saw several people I know from church. We’d also been to the bank.
Now I need to go sweep crumbs from the dining room floor, while Ash is out for a walk.
I do not understand this. You have a dog, but you still have crumbs on your dining room floor?
Your dog is deficient. Send it back for a warranty replacement.
She’s too big to get all the way under the dinner table and get all the debris from under the horizontal supports. Also, someone dropped a bunch of mechanical-pencil lead bits.
Stuff like dropping the spoon while stirring the chili, she’s great for. Slurp-slurp, and the floor’s clean. She even eats the chickpeas.
Thanks for your very thoughtful response. Of the two concerns you mentioned, I have perhaps lightly glossed over the matter of the visual delay problem, primarily because as a Myopic, it is something I've had to accommodate to periodically.
The way to minimize it might be to electronically generate the entire image, twice for each participant, and then select that portion of the image to feed each eye once the eye's focal point is determined. As you noted, eyeball tracking gear is extant, and not overly expensive. It is built into a number of cameras, allowing them to focus where the eye is looking in the scene.
An advantage for our application will be that by tracking the positions of two eyes, and comparing their angles, the focal distance can be derived quickly and accurately. This would allow the shifting of image distance you mentioned. As you said, doable.
In regard to the matter of fooling the inner ear, I agree that would be a challenge, and eventually game afficianados may wish to do such a dreadful thing.
For this application, I do not think it is necessary. We have our participant in a darkened booth, looking this way and that. This way, he sees other meeting guests. That way he sees the presenter. There should be no reason for his inner ear to disagree with his visual input.
For a "virtual reality" ski slope, it would indeed be a different matter.
My first approximation for such a mad concept would be a field of ultrasonic positioning pulses for microscopic, injectable, (and permanent), devices inside the vestibular canals. They would float freely, as our natural devices do, except when acted upon by gravity or acceleration. To overcome the natural, at rest feelings, the inner-ear devices would be maneuvered by the ultrasonic fields to give feelings of being turned this way and that.
It's possibly a workable scheme, at what expense I can't imagine, and I'm not sure whether the results would be useful enough to go forward with it.
About the only thing that speaks to its being useful is for training in flight scenarios deemed too risky for any other manner of gaining experience.
I would definitely not recommend using magnetic materials, unless they could be completely scavenged after the training, (and I would note in passing that magnetic materials would probably stand the best chance of being completely scavengable). That would make a simpler inner-ear "virtual acceleration" training mechanism.
The mechanical pencil lead-bits are harmless. They are only carbon and clay.
Actual pieces of the mechanical pencil would not be good for her.
Most toners in today’s copiers are eatable, well they are inert.
When we built our Fax Maxhine, we found out that the toner wasn't edible, it was carnivorous.
But she wouldn't eat them!
We have snow this morning. All the petz are annoyed. Anoreth's classes are cancelled. DP and I have been married 20 years today.
Denny's should be less crowded today.
Thank you. He went to work, and called to tell me not to drive because of the Global Warming.
We have just a little bit of it, so I’m going to go out and ruin its party.
Have fun! We have nice sunbeams for the petz. I need to go watch the children; they keep sneaking into the kitchen!
Also write a skit about The Bahamas. I’m thinking of a time-travel plot, so we can cover all the interesting information about pirates, flamingos, and desalinization.
Good afternoon, Undead! Made it through a whole day of math with Sally and Bill, and also found recipes for food of the Bahamas and made chicken soup for supper.
Now I need to call my choir members and tell them I called practice off, do some religion with Pat, and write the skit. I believe I’ll assign Anoreth some research - which pirates to include.
Time travel? You could borrow Darksheare’s quantum generator.
I was thinking of just having a couple of brothers hold up a sheet ;-).
I took my friend’s mother shopping at Macy’s, today. She shopped and I stood around waiting for my back to break. She bought a wool winter coat at 1/3 the original price and a cute little sweater for about 1/4 the cost and some Jockey underwear at the standard price.
Ay, yi, yi...
73 and sunny, no breeze...wish you were here...;o]
It sounds like you need a Restorative! I’m waiting until after 5:00 ...
Off to produce my “Tour of the Bahamas” skit. Maybe I’ll use a teleporter instead of a time machine. One can turn two brothers and a sheet into so many things.
