Enhanced Reality: The Virtual Reality continues crossing barriers

The enhanced Reality consists on a group of devices that you/they already add virtual information to the physical information existing. This is the main difference with the virtual reality, since you don't substitute the physical reality, but rather you overstrike the computer data to the actual world.

At this time the technique of the enhanced reality uses a similar helmet-viewer to that of the virtual reality but that incorporate synthetic (as graphics 3D) information without locking the user's view, or locking certain (for example to hide a ruin and to show in your place a reconstrución of the original construction) elements. This generates a consistent world among what we see and what we play in fundamental issues as our supportive plan, but that you allow to incorporate any imaginable element.

The games of Enhanced" "Reality fuse (AR) the physical world with the fantasy in a more and more actual way.

The Enhanced" "Reality is (AR) the field of the technology that he/she study the way to merge the actual world with virtual images. That is to say, mounting virtual images in an existing space.

How do you work? You put on shoes a backpack, headphones and some special glasses and you can scan streets or rooms pursuing or speaking with dummy beings, at the same time that you scan an unreal world.In the University of the South of Australia, for example, they have created a version AR of the popular one I play "Quake." The users use a helmet with viewer and a backpack, and the (very actual) streets of the city scan, fighting against created on-line objects that they can only see.

In Georgia Tech is using the technology to create interactive dramas, something that allow the players to have an influential network role, so that the test is something similar to a theater scenario. You would be a place where the player transforms into plaintiff and you decide, by means of your intervention, the development of the history. After Façade the investigators are creating a game call "Four Angry" Men, based on a work (Four Angry Men), where the players will debate the destination of an accused young man of murdering your father.You are hundred of possibilities in the line of the histories, and possible several ends that depend on the player's intervention. Although you seem complicated, the certain thing is that the whole process could be mounted in a console of games. The advance of the technology would even allow that some day, these virtual games can be run with something as bare as a motive. According to Steven Dow of Georgia Tech, the current generation of motives has defendant's power and the necessary resolution quality to provide fascinating tests of Enhanced Reality.

Following this line, in New Zealand, "AR is developing Tennis", a game that allow the players to use your motives as rackets in a virtual court recreated in an actual table. Billy Pidgeon, an analyst of games of the company IDC, says that the field is promising, especially for the increment of the data, transportable power and other pocket devices.

Cataract Operation of the Eye lens

He is named cataract to the operation of the eye lens, and it in fact consists on extracting it opacificado. Usually, the eye lens has the form of a biconvex lens and a size of 10 millimeters in equatorial sense and 5 millimeters of anteroposterior axis. For the accommodation quality, thanks to some special fibers, it is the one that completes the most important paper because it is the one that decides the focus of the proximate objects.

The lawsuits that can give place to the cataract are multiple. Among them hereditary factors that would determine in the mature or senile age their formation fit. On the other hand, genetic and embryological factors exist, and already in the maternal cloister he/she can the petty one to lose temper, with the following appearance of a congenital cataract that will show in the youth in occasions.

But, there are also general illnesses that can end up manifesting this illness: the diabetes, the intoxications (be due to the naphthalene, to the thallium or the rye ergot), and certain medicinal preparations that are used to cure the obesity and that they contain dinitrofenoles. Those cataracts generally enter a quite quick evolution and their only treatment consists on the operation. Other less frequent lawsuits exist, as a consequence of dysfunctions endocrinológicos pluriglandulares, as gónadas and paratiroides. In the mongolism and the mixedema it is also conserved, in occasions, the appearance of cataracts.

The most usual case is represented by the call senile cataract whose lawsuit is not still known with accuracy, but that it constitutes a positive manifestation of the age. They probably take place in the organism metabolic general dysfunctions that little by little drive to the formation of the cataract. At the beginning they are noted in one or both eyes diverse symptoms, being the main one the visual gradual forfeiture. He suits to keep in mind that simultaneously to the appearance of the cataract, the sick person can it turns affected by other eye diseases that if they are not on time, they would originate complications that can waste or to already make useless the operation of cataracts.

If the patient uses correction, he notes that her glasses don't help him I eat before, you see the deformed images and he searches a luminous more efficient focus, or on the contrary, the (when the opacificación takes place preferably in the center of the eye lens) sick person is better in the dimness, because when dilating the pupil you go with more easiness. At the beginning, it still fits some change in the corrective glasses, but as the cataract, this measure evolves it is useless, the patient loses vision and the best thing is an intervention for the expert.
