5. Robotics and TeleroboticsIn the domain of robotics and telerobotics an augmented display can assist the user of the system. A telerobotic operator uses a visual image of the remote workspace to guide the robot. Annotation of the view would still be useful just as it is when the scene is in front of the operator. There is an added potential benefit. Since often the view of the remote scene is monoscopic, augmentation with wireframe drawings of structures in the view can facilitate visualization of the remote 3D geometry. If the operator is attempting a motion it could be practiced on a virtual robot that is visualized as an augmentation to the real scene. The operator can decide to proceed with the motion after seeing the results. The robot motion could then be executed directly which in a telerobotics application would eliminate any oscillations caused by long delays to the remote site 6. Gaming How cool would it be to take video games outside? The game could be projected onto the real world around you, and you could, literally, be in it as one of the characters. One Australian researcher has created a prototype game that combines Quake, a popular video game, with augmented reality. He put a model of a university campus into the game's software. Now, when he uses this system, the game surrounds him as he walks across campus. 7. Manufacturing, Maintenance and Repair When the maintenance technician approaches a new or unfamiliar piece of equipment instead of opening several repair manuals they could put on an augmented reality display. In this display the image of the equipment would be augmented with annotations and information pertinent to the repair. Markers can be attached to a particular object that a person is working on, and the augmented-reality system can draw graphics on top of it. This is a more simple form of augmented reality, since the system only has to know where the user is in reference to the object that he or she is looking at. It's not necessary to track the person's exact physical location. 8. Consumer Design Virtual reality systems are already used for consumer design. Using perhaps more of a graphics system than virtual reality, when you go to the typical home store wanting to add a new deck to your house, they will show you a graphical picture of what the deck will look like. It is conceivable that a future system would allow you to bring a video tape of your house shot from various viewpoints in your backyard and in real time it would augment that view to show the new deck in its finished form attached to your house. Or bring in a tape of your current kitchen and the augmented reality processor would replace your current kitchen cabinetry with virtual images of the new kitchen that you are designing. INTERESTING APPLICATIONS How Invisibility Cloaks Work- If you're a fan of Harry Potter, then you're quite familiar with the concept of an invisibility cloak. In his first year at Hogwarts Academy, Harry receives an invisibility cloak that used to belong to his father. As its name suggests, the invisibility cloak renders Harry invisible when he slips beneath the shining, silvery cloth.
This seems perfectly believable when you're reading about a fictional world filled with witches, wizards and centuries-old magic; but in the real world, such a garment would be impossible, right? Not so fast. With optical-camouflage technology developed by scientists at the University of Tokyo, the invisibility cloak is already a reality. Optical camouflage delivers a similar experience to Harry Potter's invisibility cloak, but using it requires a slightly more complicated arrangement. First, the person who wants to be invisible (let's call her Person A) dons a garment that resembles a hooded raincoat. The garment is made of a special material that we'll examine more closely in a moment. Next, an observer (Person B) stands before Person A at a specific location. At that location, instead of seeing Person A wearing a hooded raincoat, Person B sees right through the cloak, making Person A appear to be invisible. The photograph on the right below shows you what Person B would see. If Person B were viewing from a slightly different location, he would simply see Person A wearing a silver garment (left photograph below).
Still, despite its limitations, this is a cool piece of technology. Not only that, but it's also a technology that's been around for a while. Police investigators and forensics specialists face challenging conditions when examining a crime scene. Often, the site of a crime can only be preserved for a short time, particularly if it's in a public area. Investigators must gather as much information as quickly as possible while doing their best not to disturb the scene itself. Also, crime photographers have to shoot scenes from multiple angles while attempting to preserve a sense of scale to ensure the pictures are meaningful -- both to investigators and to a future courtroom.
Today, some police forces are using virtual reality technology to capture and recreate a crime scene digitally. Several companies have developed numerous methods investigators can use when at the scene of a crime. Some replicate crime scenes with computer graphics similar to what you might find in a virtual reality video game. Other systems assemble photographs into a 360-degree virtual environment just like the photographic walkthroughs you may have seen on hotel and real estate Web sites. Police forces around the world have discovered that, if used properly, virtual environments can help the investigation process from its earliest stages all the way to a courtroom conviction.
