Different activities use accurate information that needs to be updated in real time, and some of the most delicate in determinations and judgments made at the time, are those who need to know the exact location of an object, its speed and movement. Determining when this takes heavy equipment, but researchers by PositionIT have created an application able to calculate distance, speed and direction of objects with a smartphone.

As a slap naive skepticism of those who thought they would succumb to give more than what was asked, now have become not only technological bells and whistles and more ways to stay connected, but also practical tools for everyday life. Applications with flashlights, complex calculations, translators, GPS maps, currency and unit conversions, bookstores and evolution of the video camera, sound recording, make smartphones even McGiver devices could get into your pocket. Now, with the invention of the engineers at the University of Missouri, much more.

Researchers have developed a prototype application that combines GPS smartphones with a compass system and other complex computations to create a model that can calculate the exact location of an object and follow its path, measuring the speed and direction leading in which it projects. Researchers say PositionIt application could allow a single portable device could replace several pieces of equipment, both for soldiers in the battlefield to engineers and mathematicians in the field geographers. Even with other utilities such as measuring distances and sports championships. The portability and it would be all that is sought to be as small as possible and parallel systems unused, although these could be used to provide further precision to the system.

The operation is as follows: when the target size is known, the software can determine the distance to the target using a single image captured by the camera of the smartphone and the comparison of their relative size in the image at actual size known target. PositionIt software then combines this information with the location's distance and GPS compass reading to compute the longitude and latitude of the object.



When the target size is not known, an additional image must be captured, so that the software can use the two images to triangulate the location of the destination. In addition, the software can also keep track of the direction and calculate the speed of a moving target from a short video captured on your smartphone. Still in development, the timing of its release is still far in advanced prototype, and all law enforcement agencies and technical occupations in the field have cast an eye on this app to calculate distance, speed and direction of objects with a Smartphone.
