Researchers have developed new software using smart phones’GPS and imaging abilities that determine the exact location of distant objects as well as monitor the speed and direction of moving objects.The software could eventually allow smart phone-armed soldiers to target the location of their enemies.On the home front,the software could be used by everyone,including golfers judging distance to the green and biologists documenting the location of a rare animal without disturbing it.

“The great advantage of a Smartphone is that it provides so many tools in a single,readily available,relatively inexpensive package,”said Qia Wang,a doctoral student who led the development of the software.“For example,on the battlefield,a soldier needs a rangefinder,compass,GPS and other tools to get information before calling in an air strike.With our software,the soldier can have all those instruments in one device that can be purchased off the shelf.When that soldier returns from War,she can use the same Software to protect her family by clocking a speeder near her children’s school and catching the criminal on video.”

Wang and his colleagues developed their software to locate and track:

Targets of known size—when the size of the target is known.a single image is enough to pinpoint the target’s location.

Targets of unknown size—If the exact size of a target is unknown,the software uses two images to triangulate the location of the target·

Moving targets—By taking a short video of a moving target,the smartphone software can calculate how fast the target is moving and in what direction it is going.

“Currently,our software is limited by the physical abilities of smartphone hardware,but the devices are improving rapidly,”Wang said.“We expect that improvements in GPS accuracy,battery life and camera resolution will allow our software to make even more accurate observations.”

When I was about 13, my father would take me on short outings on Saturdays. On the way home, Dad stopped at the Dairy Queen for lO-cent ice creams. I couldn't it, but I could pray from the we started heading home to that comer where we would either go straight for the ice cream or and go home empty-handed. That corner either mouth-watering excitement or .On one special day, we were heading home, and again I was praying for the sound of his offer ,It ,”Would you like an ice cream today?” That sounds great, Dad!” But then he said,” How would you like to today?”

Twenty cents! My mind reeled(震惊),I could afford it,I got a weekly allowance of 25cents ,plus some for odd jobs. But it wsa my money ,ice cream wasn’t a good use of it ,In a fit of ,I said ,”well ,in that case,I guess I’ll ,”My father just said,” Okay, Son,”

I that generosity(慷慨) goes two ways and gratefulness sometimes costs more than” thank you”. On that day gratefulness would have cost 20 cents and it would have been the ice cream I’d ever had.

I’ll tell you one more thing. We another trip the next week. As we the center. I said,” Dad, would you like an ice cream today? My treat.”
