The taxes were passed by Parliament in which there were no American representation. This lead to Americans protesting the taxes that lacked representation and the Virginia House of Burgess stating that "the taxation of the people by themselves, or by persons chosen by themselves to represent them The Stamp Act caused Americans to protest and refuse to buy or import British goods. The American Revolution was the first war in America 's history. However, the main factors that caused this war were, taxation, not being allowed to have representation in Parliament and being denied their rights. The first reason that the colonists and England went to war, was the fact that England was passing taxes without the colonists having a voice. Many taxes were passed that charged colonists on some of the items they used often.
This created conflict in the colonies.. Legal documents that now needed to be taxed had always been seen as business rather than to raise money. Many viewed this as an abuse of power. The Sugar Act, also known as the American Revenue Act or the American Duties Act, was one of the laws that led to anger, dislike, disagreement, and eventually revolution in Colonial America. Another effect was an increase in smuggling and crime in the colonies. The colonists did not want to pay the outrageous taxes so they looked for ways not to have to pay. A third effect was the colonists decided to stop buying luxury products from Great Britain and looked to local manufacturers for their products. They did this to avoid paying the high. American colonists protested against taxation passed by the English Parliament without any representation in that body.
The French middle class protested against the massive taxation load they had. This act is preventing us from living to our full potential. Those Brits have the willingness to come to us, the American Colonists and say that we have to pay extra taxes for something that they do as well, this act is just hypocritical. Do you want a government that forces you to do stuff without getting to have a say, or a government that will listen to you and you will get a voice in it.
In the s and 70s, tensions were rising between England and its colonies in America. This was seen as extremely unfair by the colonists, since they had no form of representation in Parliament, so the colonists had no say in what sort of laws were voted on. In other embodiments, the automobile may not maintain the spatial relationship between the virtual representation of the automobile and the actual automobile.
In this example, the all or a portion of the automobile may be depicted by the display Those skilled in the art will appreciate that the virtual content and virtual representation may interact in any number of ways. The user may view the display and perceive an aligned virtual duplicate of the actual environment i. The virtual duplicate of the actual environment is aligned with the actual environment such that the user may perceive the display as being partially or completely transparent. In some embodiments, the user views the content of the display as part of an immersive virtual reality experience. For example, the user may observe the virtual duplicate of the environment as a part of the actual environment Virtual content may be added to the virtual duplicate of the environment to add information e.
The display may be any display of any size and resolution. In some embodiments, the display is equal to or greater than 50 inches and has a high definition resolution e. In some embodiments, the display is a flat panel LED backlight display. Virtual content may also be used to change the virtual duplicate of the environment such that the changes occurring in the virtual duplicate of the environment appear to the user as happening in the actual environment For example, a user may enter a movie theater and view the movie theater through the display The display may represent a virtual duplicate of the environment by depicting a virtual representation of a concession stand behind the display e.
The display , upon detection or interaction with the user, may depict a movie character or actor walking and interacting within the virtual duplicate of the environment For example, the display may display Angelina Jolie purchasing popcorn even if Ms. Jolie is not actually present in the actual environment The display may also display the concession stand being destroyed by a movie character e.
Those skilled in the art will appreciate that the user's viewpoint may be determined in any number of ways. In one example, the display may detect the presence of a user e. The display may display the virtual duplicate of environment to the user Either immediately or subsequent to determination of the viewpoint of the user , the display may define or adjust the alignment of the virtual duplicate of the environment to more closely match what the user would perceive of the actual environment behind the display The alteration of the spatial relationship between the virtual duplicate of the environment and the actual environment may allow for the user to have an enhanced e.
For example, much like a person looking out of one side of a window e. In some embodiments, the display may continuously align the virtual representation with the non-virtual environment at predetermined intervals. For example, the predetermined intervals may be equal to or greater than 15 frame per second. The predetermined interval may be any amount. The virtual content may also be interactive with the user For example, virtual content may display a menu allowing the user to select an option or request information by touching the screen.
The 3D replica of the surrounding physical environment can be created or acquired through either traditional 3D computer graphic techniques or by extrapolating 2D video into 3D space using computer vision or stereo photography techniques. Each of these techniques is not exclusive and therefore they can he used together to replicate all or a portion of an environment. In some instances, multiple video inputs can be used in order to more fully render the 3D geometry and textures. For example, a lamp in the actual environment may be partially behind the display from the user's perspective. A portion of the physical lamp may be viewable by the user as being to the right side of the display The obscured portion of the lamp, however, may be virtually depicted within the virtual duplicate of the environment The virtually depicted portion of the lamp may be aligned with the visible portion of the lamp in the actual environment such that the virtual portion and the visible portion of the lamp appear to be parts of the same physical lamp in the actual environment The alignment between the virtual duplicate of the environment and the actual environment may be based on the viewpoint of the user In some embodiments, the viewpoint of the user may be tracked.
For example, the display may comprise or be coupled to one or more face tracking camera s The camera s may be used to determine the viewpoint of the user i. The camera s may also detect the proximity of the user to the display The display may then align or realign the virtual representation i. For example, a user standing a distance of ten feet or more from the display would perceive less detail of the non-virtual environment.
Although FIG. Any information may be used to determine the viewpoint of the user In some embodiments, camera s may detect the face, eyes, or general orientation of the user Those skilled in the art will appreciate that tracking the viewpoint of the user may be an approximation of the actual viewpoint of the user. In some embodiments, the display may display virtual content, such as virtual object , to the user In one example, the virtual object is a bird in flight. The bird may not exist in the actual environment as can be seen in FIG. A digital device is any device with a processor and memory.
In some examples, a digital device may be a computer, laptop, digital phone, smart phone e. Digital devices arc further discussed with regard to FIG. In various embodiments, the digital device may be coupled to the display For example, the digital device may be coupled to the display with one or more wires e. In some embodiments, the display may comprise the digital device e. The digital device may comprise a display interface module , a virtual representation module , a virtual content module , a viewpoint module , and a virtual content database A module may comprise, individually or in combination, software, hardware, firmware, or circuitry.
In various embodiments, the digital device may drive the display For example, the display interface module may comprise drivers configured to display the virtual environment and virtual content on the display In some embodiments, the display interface module also comprises interfaces for different types of input devices. For example, the display interface module may be configured to receive signals from a mouse, keyboard, scanner, camera, haptic feedback device, audio device, or any other device. In various embodiments, the digital device may alter or generate virtual content based on the input from the display interface module as discussed herein.
In various embodiments, the display interface module may be configured to display 3D images on the display with or without special eyewear e. The virtual representation module may generate the virtual representation. In various embodiments, a dynamic environment map of the non-virtual environment may be captured using a video camera with wide-angle lens or video camera aiming at spherical mirrored ball, this enables lighting, reflections, refraction and screen brightness to incorporate changes in the actual physical environment. Further, programmers may use digital photographs of the non-virtual environment to generate the virtual representation. Applications may also receive digital photographs from digital cameras or scanners and generate all or some of the virtual reality.
In some embodiments, one or more programmers code the virtual representation including, in some examples, lighting, textures, and the like. In conjunctions with or in place of programmers, applications may be used to automate some or all of the process of generating the virtual representation. The virtual representation module may generate and display the virtual representation on the display via the display interlace module In some embodiments, the virtual representation is lighted using an approximation of light sources in the related non-virtual environment. Similarly, shading and shadows may appear in the virtual representation in a manner similar to the shading and shadows that may appear in the related non-virtual environment.
The virtual content module may generate the virtual content that may be displayed in conjunction with the virtual representation. Virtual content may be generated or added that alters the virtual representation in many ways. Virtual content may be used to change or add shading, shadows, lighting, or any part of the virtual representation. The virtual content module may also receive an indication of an interaction from the user and respond to the interaction.
In one example, the virtual content module may detect an interaction with the user e. The virtual content module may then respond by altering, adding, or removing virtual content. For example, the virtual content module may display a menu as well as menu options. In one example, the virtual content module may be configured to detect an interaction with a user through a gesture based system. In some embodiments, the virtual content module comprises one or more cameras that observe one or more users. Based on the user's gestures, the virtual content module may add virtual content to the virtual representation.
For example, at a movie theater, the user may view a virtual representation of the theater lobby in the user's non-virtual environment. Upon receiving an indication from the user, the virtual content module may change the perspective of the virtual representation such that the user views the virtual representation as if the user was a movie character such as Iron Man. The user may then interact with the virtual representation and virtual content through gesture or other input.
For example, the user may blast the virtual representation of the theater lobby with repulsors in Iron Man's gauntlets as if the user was Iron Man. The virtual content may alter the virtual representation to make the virtual representation of the theater lobby appear to be damaged or destroyed. Those skilled in the art will appreciate that the virtual content module may add or remove virtual content in any number of ways. In one example, the shape of the object i. The virtual content module may also add reflections. In one example, the virtual content module extracts a foreground object, such as a user in front of the display, from a video e.
The virtual content module may render the virtual content with the non-virtual environment in all three dimensions. To this end, the virtual content module may apply z-depth natural occlusions to virtual content in a manner visually consistent with their physical counterparts. If a physical object passes between another physical object and the viewer, the physical object and its virtual counterpart may occlude or appear to pass in front of the more distant object and its virtual counterpart.
In some embodiments, the physical display may use a 3D rendering strategy that can reproduce the optical lens distortions of the human vision system. In some embodiments, the viewpoint module determines the viewpoint by detecting the presence of a user in a proximity to the display. In one example, the viewpoint may be fixed for users within a certain range of the display.
In other embodiments, the viewpoint module may determine the viewpoint through the position of the user, the proximity of the user to the display, facetracking, eyetracking, or any technique. The viewpoint module may then determine the likely or approximate viewpoint of the user. In one example, a user in close in perpendicular proximity to a display may increase the viewing angle into the virtual representation and conversely, the user moving away may decrease the viewing angle.
An optimization strategy, based on a conical degradation of visual complexity which mimics the degradation in the human visual periphery resulting from the circular degradation of receptors on the retina, may be employed to manage the dynamic complexity of the rendered content within any given scene. In some embodiments, once a position of a face tracking cameras is established, an extrapolated 3D center point along with a video composite of camera images may be sent to the viewpoint module for real-time evaluation. Utilizing computer vision techniques, the viewpoint module may determine values for the 3D position and 3D orientation of the user's face relative to the 3D center point.
In some embodiments, eyewear may be worn by the user to assist in the face tracking and creating the view point. Those skilled in the art will appreciate that the viewpoint module may continue to detect changes in the viewpoint of the user based on changes in position, proximity, face direction, eye direction, or the like. All or part of the virtual world, including both the virtual representation and the virtual content, may be presented in full scale and may relate to human size. The virtual content database may comprise a computer readable medium as discussed herein. In some embodiments, the virtual content database stores executable instructions e. Furthermore, royal officials continued, in some areas in England that were represented in the House of Commons, regular people did not choose who represented them.
Instead, the local nobility or the king himself picked their representatives. In fact, King George III personally appointed more than 50 members of the House of Commons, which was more than ten percent of the entire chamber. So, British officials concluded, virtual representation was a reasonable and generous solution to the impasse over the Stamp Act. The colonists did not at all buy the explanation of virtual representation. Legitimate political representatives, colonial leaders argued, should be chosen directly by the people for whom they spoke.
The theory of virtual representation did not fit this definition in any way. John Adams , an influential colonial leader and future president of the United States, claimed government representatives should actually reflect their constituents. Very few colonists accepted the British argument for virtual representation. In the face of such fierce colonial resistance to the idea of virtual representation, King George III gave his approval to rescind the Stamp Act, and in Parliament repealed the law. However, British officials made clear they were not yielding to colonial demands, only following the lead of the king.
To drive home this point, the House of Commons passed the Declaratory Act , which reiterated its right to pass laws for the colonies in all cases. Many felt the repeal of the Stamp Act was of little consequence if British authorities claimed the power to do anything they wanted in the colonies.
