Virtual reality theme park experience report it takes courage to step into the

Prior to this, Lei feng's network introduces a virtual reality theme park called The Void, it is a mixed reality experiences, built on top of the physical world to virtual world, allowing users to feel objects around and use real property, such as a lantern, sword, gun, etc. RoadtoVR reporter Chris "DeepRifter" Madsen to experience in a circle, let's take a look at his experience report:

If we were to measure the quality of virtual reality and Telepresence is a basis for benchmarking. So-called telepresence is your brain that this experience is real. When you spot, these virtual experiences are our brains think of what is happening is real. Therefore, both mentally and physically, users respond to virtual environments and the reaction there is no difference in the real world.

How to bring a higher degree of telepresence has many ways. When you spot as if a switch is being pressed, and suddenly you are no longer an observer, but as a participant. The VOID in the virtual reality company from Salt Lake City, Utah, for Telepresence to create, take the form of simple and direct, gross and effective.

Last week, the company announced that they will be virtual reality into the world of commercial entertainment level, saying they have "advanced virtual reality technology, will allow you to completely immerse in a real way to view, move, or even feel this digital world. Rather than watching a movie or playing a game ... ... Here you live in it. "Video was also released.

And 2 million hits a week on YouTube telling us that the world's attention seems to be they seduce.

It seems that they already have considerable research on virtual reality, The VOID was in various ways, including custom systems such as VR, wireless location tracking, physical tracking, 3D stereo sound effect, force feedback, as well as physical props, real-world interactions and other means to maximize the use of Telepresence.

VOID said their next VR head "The Rapture" has some special features, as well as having Oculus,HTC/Valve and Sony's current products are higher than the specifications. CEO Ken Bretschneider said, because of their positioning is not a consumer-level with the head of the family, so they can regardless of the cost to build some of the first, was greatly enhanced by Telepresence.

Hardware prototypes VOID over time will be announced, and Ken is also hoping to put our group of people wishing to enter the virtual reality fast all day long on the West. The VOID (Vision of Infinite Dimensions) by combining virtual reality and real-world individuals, family and friends shared interactive experience.

The world stepped into the VOID

James Jensen is the Technical Director of The VOID, as my tour guide let me experience the "Pod" prototype, they built a real/virtual environment. I followed him to the lab in the background (can't take pictures) and see a number of stage equipment, such as movable walls that create mobile corridors, rooms of varying sizes, props, as well as environmental effects devices. This is a 900-square-foot (90 square meters) cabin prototype, may later be extended to 3600 square feet.

This cabin is designed to be the physical building structure and virtual worlds combined together, if I see a railing in the virtual world, I can reach out to catch a physical fence, which greatly increased the use of Telepresence. Artists bring their imagination to the full space, to create a complete 360 ° 3D immersive experience.

Of course, before starting the experience I needed to install equipment. Come to the dressing room, Jensen gives me a backpack, is actually a small chassis, which is the order of the host system. When I was back, I am actually surprised this box looks much lighter than the aluminum back. Tight bandages, Jensen said at the time of listing, this will halve the size of the box.

Followed by helmets, intercoms, an Oculus Rift DK2 and location tracking device; these are temporary substitutes until they were ready to provide equipment to the public. Experience is, of course, a full range of wireless, and my location was better tracking camera on the ceiling. I wear this stuff, standing in the control room, waiting to initialize their calibration.

All right.

I turned and saw a sparkle appeared in the room. I move the body before and after look at surface of this portal is covered by waves of light, and then take a deep breath, like Alice in General, plunge into the VOID.

Looks like, I came to a factory. Since there is no line, I can just walk around in this virtual world rendered. Walk five steps, my heart beats faster, the wireless way I think is like walking into a dream. Ten steps later, I walk around shaking his head back and forth to see whether to get rid of this illusion. No significant delays and inaccurate tracking, my physical and virtual locations seems to correspond very well.

Telepresence is increasing. When I reach out to touch the box, touch the authenticity of the wood with the touch screen doubles. I even hand imposed on body weight to do push-ups, and carried back to him. Prop is completely corresponds to the position.

Here, you can understand real-world material, and the virtual world is to add texture

A few steps away there is a bench called I used to sit on it. I stopped for a moment, it reminds me of the experimental Oculus Rift comes with demo results want to pull a virtual table when a sit down experience. Ask Director so I doubt it is true.

"Trust your heart. "He said. Hear so philosophical discourse, I whole body full of energy, went over and sat down. Sure enough, or one by one.

However, one thing I didn't expect-which is also a magician's lair. The VOID is the Creative Director of Curtis Hickman, already has 20 years of experience in magic, and David Blaine, lansibodun, are good friends. He produced a large magic with David Copperfield, kelisianjier recent Mindfreak series also used some of his ideas. In addition, he is also an award-winning Visual effects and animation artist.

And Curtis talked about the design of the cabin of the virtual experience and how to stage design to achieve the maximum effect, how to use both virtual and real items to create some illusion, to be called is "digital magic". Hickman has considerable enthusiasm to create these experiences looks, because he was using his magic and knowledge to manipulate the stage actor's brain.

When I first got him, happened to me before leaving a virtual room, when I was standing at the end of a very long straight corridor. I watched the digital generation Sun is shining nobody corridor and floating dust, walks from head to tail, and after coming to the end of Jensen stopped me and asked me to open the helmet, looking back. This corridor is not straight at all, although my brain thought it was straight. Look at the curved corridors I don't see the point. I had no knowledge of it through the so-called "walking boot".

Guided walk, is a subtle visual changes to booting from a subconscious subjects walking directions, while they consider themselves completely in Shimei skills. This success is because of our visual perception completely covered our vestibular sense, which is commonly known as the get lost in the dark night. Use this ghost can let us know the truth of the situation all around the circle. Suddenly, the actual amount of physical space has become less important. Using this technique and special custom props, stage combined to break the physical boundaries, create unlimited exploration of space. This brings the possibility of how much more?

After walking around this virtual workshop for some, I'm completely not aware of his place in the real world. I walk through a door, found the plant to be inserted in a cliff hanging in midair, alien ground almost at the foot of several hundreds of meters. I was standing in the road, all the different view a panoramic view. When edge when a gust of wind blew I stumbled almost stand still. There is a little distance from the border, I was squatting and shirt dancing with the wind, beating my little body.

Of course, virtual reality is not the Elimination of our memory. I know exactly what is in a simulator, my guide will make sure that everything is safe. But know that this does not mean that understand this, especially when I found out that I have to push yourself to move forward only. This little hesitant to be similar to when the counter, father coax you to don't be afraid to jump in the following he will catch you.

 Curtis Hickman (left) and James Jensen (right)

Finally, I held death die attitude, forward stepped up my pace, I was greeted ... ... Air! For a moment I panicked, I gaffe is not described, but the physical distance of about 30 cm below the edge. Jensen laughed and said they found a little distance can kill people. Hickman in the back laughing. I am not happy.

Shows the last, walked into an elevator on the second floor. When I walked in, and Visual shocks to the foot of the rise and make it all so real, and the armless, open around the net closed eyes open elevator scene made my knees weak. When looking at just when the platform further and further from my feet, this illusion is impossible to break. I came to the second floor, but in the real world, in fact I did not move a muscle. Jensen said he brought people to come here, often lying on the floor calling him (thought he was at his feet), and did not know he was in front of him.

Reluctantly return to prepare, I took the equipment, adjusting the emotional state. As the players of virtual reality, owner of the DK2, try this wireless tracking of large environments is very cool. Beautiful time is always short, when millions of dollars of investment into here to ensure that the quality of the entertainment center, a group of talented artists understand virtual reality magic worked, as well as custom high-end immersive virtual reality equipment, VOID will be a leader in large-scale virtual reality entertainment.

People and computers what to who controls the steering wheel

In certain scenarios, a luxury car has been fully able to finish the task, for example, neatly parked on the parking space, automatically driving at low speeds on the road. But some people doubt that full control to a machine is the right choice. United States Cambridge, Massachusetts, a startup company nuTonomy, is working on automatic driving technology, designed to improve the driver's driving experience, and allows the humans to better control of the car.

Traditional automatic computer systems before you plan your ideal route, usually with radar, GPS and other sensors to analyze the information and nuTonomy designed the algorithm can mimic human style of driving, and to develop a safe driving program. Cars fitted with the company's software, you can automatically select the best route. Using this method, you can combine human and computer-controlled more smoothly. For example, the system can monitor the driver's steering, only when the actual routes deviate from software-defined when driving a routes, the system will intervene.

"The current problem is, human and automatic driving system tasks are not the same", Karl Iagnemma, founder of nuTonomy believes that "If there is no particular course of conduct, this could mean the car appears out of control of the autopilot system, which upset many drivers. "

Iagnemma revealed that nuTonomy is also developing new methods to test and validate an automated driving system performance in all possible cases, which will contribute to the promotion of a more complex automated driving. He also added that the company is a luxury car manufacturer to focus on production.

Vehicle automated driving technology has been developing for decades, adaptive cruise control system was introduced in 1990, automatic parallel parking is also appeared in early 2000. But recently, it seems to go very hard, such as the latest BMW 7-series, when the driver got out of the car, you only need to press a button, the car will automatically stop warehousing. Some Mercedes-Benz models can automatically drive in low-speed roads, Audi and Volvo plans to introduce the technology next year.

However, the rapid development of autonomous vehicle technology is not only on the roads, the highway will also introduce the technology, it is estimated that this year and next year will be an important milestone in the development of the technology. Tesla has said it will release an update for the Model s, when the vehicle when driving on the highway, by loading the necessary sensors to control vehicle speed and steering. Cadillac next year plan to provide similar technology in some models. Burberry iPhone 6 Case

However, the introduction of this technology may make people more and more worried about driver distraction, especially when the driver suddenly when you need to control your car. For now, Cadillac has not indicated how the driver of the surrender or recapture control.

 

Automatic car driving is a big cake, car manufacturers not only in research and development, has also attracted a lot of technology companies. In addition to Google and its driverless car, Uber by cooperating with professional academic researchers at Carnegie Mellon University, suggesting it for driverless technology ambitions, even the rumored Apple in the development of autonomous driving technology.

Car automation, we face a choice: are humans driving, depend on their cars and, in exceptional cases also is letting the car driving in special situations rely on humans? What do you think about it?

Material on the side teaches you DIY mobile phone special portable projector

Now, the ever-changing mobile phone, but the function is much the same. Bring the iPhone since jobs, mobile phones can not see the keyboard, looks more like a small monitor ... ... However, the screen is bigger, more episodes or something bad, you can DIY a small box, turn the mobile phone into a portable projector.

This project only according to the principle of making, the actual effect is for reference only.

Mobile projection principle

Regardless of is real of projector, also is today to do of this phone projection box, actually principle are is simple, that is "convex lens imaging", this in middle school physical in the on introduced had has: Dang objects put in convex lens focus zhiwai, in convex lens another side into inverted of blending, also has a formula: real (from) far like (from) near small, real near like great. Projector is by adjusting the distance between lens and projection source, to change the size of the projected image.

Principle of the projector

When it comes to projecting sources, projectors currently has a variety of types, common to both LCD and DLP. DLP (Digital Light Processing, digital light processing) technology is Texas instrument company of patent, its core is a digital micro-mirror chip, this is a arranged with countless "small mirror" of chip, each a pixel corresponds to with a "small mirror", it relies on of not change incident light of polarization State or itself glow State, but adjustment specific location micro-reflection mirror of reflection angle--if need some pixel of location glow, on drive small mirror, let light reflection to lens So images appear on the screen. Clearly, the way DLP works too high end, not suitable for DIY production. LCD projector technology is much easier, especially now that many DIYer often used the principle of single-chip LCD projector: using the LCD screen as translucent screen, images directly through the lens is projected onto the screen.

So, I use a mobile phone as the projection source, so don't need to consider issues such as light, heat, the only regret is, the brightness of the screen is not too high, after lens refraction and scattering, the brightness of the projected limited, can only be used in darker environments.

Summary projection box internal structure

Design and material selection

Based on the above principles, we can put the "projector" very simplified: projected as mobile sources, using a single convex lens or a Fresnel lens of the camera, a correction like mirrors, combined with a compact and lightweight box is OK.

Projection source--cell phones:

LED projector resolution is determined by the LED screen resolution, use mobile phones as a LED projector projection source, a large screen, high brightness, high resolution mobile phone is necessary. I used the OPPO Find 5 sponsored by the OPPO cell phones as LED projection sources, it has a 5-inch 1080p screen, 1920x1080 resolution, pixel density of 41ppi (Pixels per inch, number of pixels per inch), by refraction of the lens zoomed in, better reflects the advantages of fine quality. Because we want to make a projection light source projector, the source of all the light from the screen itself, OPPO Find 5 phone screens up to 480 lumens brightness, the drop shadow effect is good. In addition, the OPPO Find 5 occupied nearly the entire front screen of the phone, the border only 3.25 mm, so you can make the box as small as possible, reduce the scattering of light, very suitable as a mobile projection source.

Projection source: OPPO Find 5 mobile

Lens:

Greatly simplifies the structure, if using a regular convex lens, corners will appear dim and fuzzy phenomenon. This is because the refraction of light occurs only in the media interface, convex with a thick, light travels in straight lines in the glass part will make the ray attenuation. If you can remove the straight part, leaving only the bent surface, it can save a great deal of material at the same time achieving the same spotlight effect. Fresnel lens is to adopt this principle. Fresnel lens looks like a unlimited number of concentric lines (Fresnel zone) of glass, but it can achieve the effect of convex lenses, projection light source is directional, brought together project to keep a consistent brightness throughout the image, so I used as the projector lens feinier lens.

Reflector:

Convex lens image is inverted real image, although now the phone screen with 180-degree rotating function, but cannot control the flip, so to see a normal text and images, use a small mirror to solve it.

Box:

In order to minimize phone projection, according to the dimensions of the phone and the Fresnel lens focal lengths, calculate the best size. Box, stiff cardboard, paper boxes, PVC plastic and all, principle is to minimize light tight, inner wall are also not reflective.

Card materials

Fresnel lenses, mirrors, light wood, non-woven fabric

Shell material is 3mm non-woven, lined with a cell phone/mirror mounting bracket, 3mm balsa sheet production.

Production process

Based on the previously calculated distance, designed a box size, make good parts of the box with a cardboard template. Author tests found that distance between reflector and Fresnel lens at about 7CM, to throw about 20 at a distance of 1.5-inch clear images.

Implementation prepared paper template first, draw the outline of the various parts in the non-woven, cut out with scissors.

Fresnel lens dug holes to fix the lens (side towards the inside of the lines).

Between the two sides of the box and the box using the stitching process, resorted to killing machine--a sewing machine.

Balsa sheet to make a mirror frame, used to place the phone on the bottom.

Give feinier lens in front of a border, so as to underpin the box, fit right in.

Box shaped.

How to make it cover more beautiful? Metal buttons-the need to use a hammer to buttoned.

Solve the problem of lid, and cell phone/mirror bracket in the box and you are done!

See the final look!

Projection box ready, phone fixed bottom position how to control a mobile phone cell phone? You can use the Bluetooth mouse if your cell phone and operating systems support for Bluetooth transmission.

Room for improvement

First of all, is the material of the box, if it is possible, you can use sturdier materials, such as wood or glass materials, made with black shade cloth lining.

Now due to the fixed size of the box, the object distance is not adjustable, Fresnel lens in the front end if you can move back and forth, cast images can be resized and, of course, clear projection distance (distance) have to rely on your mobile.

Super cute button details are lovely with dust plug post

Said the key post, most of the products on the market are similar: rounded, with glue on the back, front convex, printed with a variety of patterns. Did you ever see not rounded button stickers? Did you ever see keys without glue stick? You saw with dust plug button with it? Never seen? Then meet it. Moschino Galaxy S3 Case

This Naughty animal button post, paste the installation is not used, but rather through the dust plug firmly upon machine. Transparent dust could hardly see it, looks and pasted directly effects.

Naughty animal keys keys stick than ordinary button paste paste is rubbed off. Naughty animal button post is not in the package under the friction of debris fall off easily. Bad key sticker off leaving behind unsightly offset printing. While it does not have this problem. Thin buttons on the stick handle is not enough.
