This is the VOA Special English Technology Report.
More than twenty thousand new products appeared at this year's International Consumer Electronics Show in Las Vegas, Nevada. Among the attention getters were "ultrabooks," or very thin laptop computers. Also, Microsoft announced new smartphones with the Windows Phone operating system.
Far from the bright lights of Vegas are the poorly lit streets of Delhi. A new mobile app called Fight Back aims to make those streets safer for women like Cheena Sikka. She often works late. A company taxi takes her part of the way home, but then she has to walk five to ten minutes alone. "It's dark and the kind of people who are around are not really to be comfortable with or safe," she says.
Ms. Sikka uses Fight Back to follow her location with GPS, or global positioning system, software. Jagdish Mitra is the head of CanvasM Technologies, which launched the app. He says, "The moment you feel uncomfortable, you really don't need to do anything else but press one button."
The woman has a few seconds to cancel her decision. If not, a message with her location will go by text, e-mail or Facebook to anyone she has put on a list. The location also appears on a map in the company's offices. But Mr. Mitra says his company does not serve as a public monitoring center. "The law has to be managed by the people who actually are authorized to do it, which is the police and so on and so forth."
Officials reported more than four hundred rapes in Delhi in twenty-ten. Many media organizations have called the city of seventeen million people "India's rape capital."
Kalpana Viswanath is a researcher with the women's group Jagori. She works to make cities safer for women through changes like better lighting and wider sidewalks. She supports Fight Back but has some concerns. "While the app to me is very important and has a good role to play, I think what we have to be careful about is that it doesn't again fall back on women to solve their problem."
The makers of Fight Back say police in Delhi and other Indian cities have expressed interest in linking to the system. Hindol Sengupta is a founder of Whypoll, a nonprofit group that works on the Fight Back project. He says Indian police often do not take women's safety seriously. He says, "Most women don't go to the police because in most parts of the country, the police are seen as more part of the problem than part of the solution."
