GPS (Global Positioning System) is a satellite based positioning/navigation system. In the last 10 years it has become part of our everyday life. Virtually all private and commercial airplanes and ships navigate using GPS. If you take a taxi, chances are it is being located for dispatch and for safety reasons using GPS. It has become affordable to a point that a small, simple, portable model sells now for less than € 200 and it is a must for whoever is about to go trekking in scarsely populated areas.Yet one wonders why this technology hasn't so far been used in favour of less advantaged categories of people such as "special needs" carriers, the ill, the elders and, at such a low price, even for ordinary people who conduct an ordinary lifestyle while serving society playing a fundamental and not easy role: parents. Also, in a context where distances are shrunk by modern means of transportation and communication; in societies where the single parenthood is becoming standard and where the "single parent" is usually a woman, one wonders why a more widespread application of the GPS technology hasn't yet become an issue.I am personally very impatient to see what the next few years technologies will provide us.
