The headsets of tomorrow offer some amazing possibilities in both gaming and work, but what we've seen so far only begins to scratch the surface. The US Navy saw the potential to use augmented reality in a helmet to provide divers with an incredible amount of information we have so far only seen in Hollywood movies.
This video details how to do easy yoga poses for beginners. To start out, assume 'mountain pose' which involves placing the feet at about a hip width distance apart. After the feet are placed, lengthen up through the spine and roll the shoulders back while also tucking the chin slightly back. Arms are then raised upward while inhaling, and lowered while exhaling and in the same exhale lift out of the hips, hinge, then enter a forward bend. Note, it is acceptable to bend the knees in this proc...
This instructional video will show you how to properly wash and keep your wetsuit nice and clean. This helps for scuba divers, snorkelers and if you surf, boogie, or bodyboard.
If you're a serious diver, especially anywhere cold, then your dry suit is probably a near and dear friend. If something goes wrong with it, you may think that you need to pay someone a lot of money to fix you baby. But no! They're actually pretty easy to fix yourself. This video will show you how to fix the neck seal on an OS Systems drysuit yourself with just some spare parts that you can order from the manufacturer.
As if the world needed one more reason to be obsessed with Shark Week, Volkswagen has teamed up with Discovery Channel to create this awesome "underwater car" that's actually a mobile shark cage.
Help Alan Wake uncover the mysterious disappearance of his wife in the small town of Bright Falls. This isn't your ordinary video game, so be prepared for a different kind of gameplay! And these videos will help you get through the first episode in Alan Wake on the Xbox 360. Not just that, but you'll see how to beat Episode 1 on Nightmare Difficulty!
A magic trick in which you appear to make a straw and paper clip float freely in an empty water bottle. This also makes a great science lesson about water pressure.
The pressure underwater is undeniably strong. If you were to fill a balloon with water and take it underwater, it would not burst but would stay the same size because liquids are not compressed. The pressure is the same, inside and outside of the balloon. If you were to fill that same balloon with air instead, the lower it dives into water, the more it shrinks, until it eventually can't take the pressure anymore and bursts.
Of all the ways I thought I'd be watching my favorite TV shows, on a floating orb was not one of them.
If you've ever wished you could keep tabs on the fish in your aquarium, Justin of Antipasto Hardware Blog has just the mod for you! He created this DIY "shark detector" that sends out a tweet whenever Bruce the shark breaches a perimeter that he set up in the tank.
Just like in the Spy Kids 3D movie, US soldiers may soon upgrade their mission planning from 2D to 3D. Welcome to the wonderful world of augmented reality, US Army.
If you prefer glow sticks over candles during a power outage, then this how-to is for you! Although glow sticks are used as temporary light sources, there are other applications for them. Divers use them for night diving, fisherman use them to catch swordfish, and the military uses them for light markers, along with infrared versions used in conjunction with night vision devices. But with all these handy uses for glow sticks, the most popular is — recreational use, like dancing at raves, some...
The limitless applications of 3D data visualization will enable a more efficient approach to many of life's problems. Each day, developers exploring this technology are finding new ways to solve these problems in mixed reality; 3D modeling, easier house management, spinal surgery, and forest fire management are just a few recent examples of ways 3D data visualization can benefit us all.
As a commercial and potentially consumer product, one might assume it very unlikely to see the Microsoft HoloLens in the military marketplace. And that assumption would be completely wrong. One company from the Ukraine is currently working on using the mixed reality head-mounted computer for 360-degree vision inside armored tanks. If a tank crew could see the entire battlefield there are in, they would likely have a better chance of accomplishing their mission and avoiding damage. Tanks are l...
If there's one way to get a visceral response from someone, it's bringing up the DMV. Regardless of the reason, whether it's the long lines, disgruntled employees, or just general inefficiency, I have yet to meet a single person who doesn't mind the trip. Just look at all those happy faces.
The Weather Channel, by virtue of its name, has always been tasked with the difficult problem of making the weather interesting. As Mashable notes, they've turned to augmented reality for a solution and can now render a 3D storm in their studio, as well as help us understand how bad a storm might be with 3D forecasts.
While flying isn't easy, once an airplane gets into the clouds there isn't a whole lot to worry about—most of the work happens during takeoff and landing. Helicopter pilots, on the other hand, have a lot of dangerous obstacles (like power lines and buildings) to contend with. But, once again, augmented reality can save the day.
If you love the ocean and love swimming, it's time you step up to the next level… snorkeling. Snorkeling is one of the best ways to explore the underwater life, without fancy equipment or expensive training. And all you need is a snorkel. If you want a better look at what’s underwater, all you have to do is snorkel.
Just as Apple, Snapchat, and other tech giants are working on augmented reality wearables in the race to replace smartphones for the future of mobile computing, so is Samsung.
Remember Photo Booth on Mac and iOS? It still exists, but there was a of time where everyone was using it. And why not? It was so cool to take photos with any background imaginable. Underwater? Check. On the moon? Of course. Now, Instagram wants to bring back the fun by introducing AR backgrounds for stories.
With Google Maps, we can fly from Los Angeles to Tokyo to Paris and New York—all in a matter of seconds. We can zoom in with relative ease and flock around the city of our choice, checking out restaurants, historical landmarks, traffic and scuba divers. Easily the most recognizable and iconic part of Google Maps are the markers that signify all of these locations and point of interests. The iconic markers have already spurred artists to create Google Map inspired art pieces—with one such arti...
The next time a light bulb burns out in your house, don't throw it out. Believe it or not, burned out light bulbs aren't entirely useless. Besides creating an extra task on your to-do list, they can be hollowed out and used for a variety of different things from home decorations to miniature indoor gardens.
Glow sticks, a popular favor at parties and outdoor events, and a must-have on Halloween, can be traced back to the United States Navy in the mid-1960s. The military desired improved visibility during night operations, and glow sticks, with their small-size portability and lack of batteries, were a perfect tactical solution.
Learn how to make an ocean in a bottle. This video shows how to make a Cartesian diver. It is named after Rene Descartes, a famous French scientist, mathematician, and philosopher. Make an ocean in a bottle.
The idea is to get at least three of the guys to go to a zoo with an indoor alligator pond inside one of the indoor buildings with a railing around the pond. The pond needs to be murky and anyone looking down at the pond should not be able to see more than a foot down in the water. A fake alligator head on a hydroaulic cylinder will be floating at the surface near one side of the pond as that is usually all you can see of an alligator when it is wallowing in the water anyway. A scuba diver wi...
Its a quick slip and dive to the finish, well the end of the course,The idea is a slip and slide down a rough course of mud and water, snaking about side to side, while having hay and saw dust thrown at you at first, then the nasty stuff begins!horse dung is thrown at you while you slide down and then there is a ramp, and at the other end, is a huge pile of horse and cow dung!...The diving is judged by a panel of 3 judges and the person scores the best dive wins!Its that simple!
Amazing compilation video of thrill-seeking junkies making insane jumps. The top ten covers everything from base jumping to skiing to motocross to finally, what might just be the most insane: back in 1960, Joe Kittinger jumped from the edge of space in a giant helium balloon. Previously, Supersonic Space Diver With Death Wish.
Quick, winter is coming to a close, time to catch the tail end of the winter sport season. This could potentially include ice diving in Kaindy Lake (if you happen find yourself in Kazakhstan, home of Borat). Kaindy Lake was created by an enormous limestone landslide, and as a result, a forest was submerged. In the summer, half drowned trees emerge from the water, creating a dramatic effect. In the winter, ice divers brave the freezing waters to explore the depths.
There is no discount like free. And if you are not afraid to get your hands and clothes dirty foraging through dumpster bins, trash cans and the back alleys of department stores or restaurants to score perfectly usable items and perfectly edible food without paying a single cent, then dumpster diving might be right up your alley.
Giveaway Tuesdays has officially ended! But don't sweat it, WonderHowTo has another World that's taken its place. Every Tuesday, Phone Snap! invites you to show off your cell phone photography skills.
Yup, that's right! There is a new larp starting up near me, called Cobalt Nightmares, where the theme is Post Apocalyptic Fantasy. I have to admit, I absolutely adore the Post Apocalyptic genre (especially that awesome Fallout LARP in Poland), and I'm interested to see what happens when it becomes a fantasy game instead of a science fiction game.
Would you rather live far up in the trees? Or deep underwater? A Nevada family of scuba divers have built the ultimate childhood getaway: the Needham family's "Bubble Room" is an underwater fort that sits at the bottom of a lake in the Sierras. The room is an air-filled pocket, made with vinyl and anchored down by an octagonal framework of metal pipe.
It's been almost a century since we've last seen Kid Icarus start in his own game! The result of Project Sora, Kid Icarus will be released for the Nintendo 3DS!
Daring or just plain stupid? French X-game medalist Taig Khris sets a new world record, jumping from the first floor of the Eiffel Tower. The rollerblader dove from a height of 131ft onto a massive quarter pipe ramp. There is some controversy over his newly earned title, however.
If you thought playing Scrabble in your grandparents' kitsch and musty old house was your most dangerous gaming experience, you haven't heard of Extreme Scrabble yet.
Felix Baumgartner plans to leap a record 120,000 feet, breaking four world records. If all goes well, Baumgartner will set records for highest altitude freefall, longest distance freefall, highest manned balloon fight, and fastest speed freefall (he will actually break the sound of speed!).
