Introduction: - Touchscreen phones are becoming a part of our lives more and more each day. This is due to the fact that the touchscreen control method allows a device to be navigated much more easily, quickly and intuitively, since you
can activate given applications by touch, rather than having to press a button multiple times (e.g. the D-pad). There are a few different types of technology that can be used to achieve this control method, each of them having its pros and cons.
The beginning:- The father of the touchscreen technology is Dr. Samuel Hurst. In 1971,
while he was working as an instructor at the University of Kentucky Research Foundation
months so that two students could graduate. In an effort to save some time he invented the first touch sensor tha the called „Еlograph” (electronic graphics), which allow
ed him to enter data faster. Alongside with this invention the company „Elographics” was born (known today as Elo TouchSystems). This device was not transparent as today’s sensors are, but this achievement was a big move towards the modern touchscreen. Three years later, in 1974, Dr. Hurst designed the first transparent touchscreen, and in 1977 Elographics invented and patented the 5-wire resistive technical method, which is still the most widely used one today.
Touch Screen Phones:-
Touch-screen technology for mobile phones is generating considerable interest from consumers, and it is starting to grow significantly. By the end of 2007, momentum will be very strong for the technology, and by 2012, 40 percent of all mobile phones will likely utilize touch-screen technology.
"The touch screen market in cell phones is nearly ready to take off, but before it can do so, certain conditions must be met," said Stuart Robinson, director of the handset component technologies service at Strategy Analytics, the Boston-based research service.
Lower Costs, Higher Demand:-
First, Robinson said, the cost of touch screen technology must shrink from its current price of US$5 to $10, to under $3. Then, Robinson said, revenue-generating applications must be developed to differentiate touch screen devices from menu or icon driven phones. "Finally, the market requires a catalyst, such as th
e presence of an iconic touch screen phone in a
These touch screen interfaces for mobile phones will remain at under 2 percent of total devices until such a catalytic event occurs, most likely at the end of next year. Once that happens, fast growth will generate interest in touch s
creen phones, growing the market to around 40 percent.
"We expect most demand to come from finger-sensitive technology built into high-end feature phones," said Stephen Entwistle, vice president of Strategy Analytics. "This will be a significant shift from today's wireless PDA segment, where most stylus-driven touch screen devices can be found.

robust yet has a lightweight outer-shell. The combined Fujinon 10x optical zoom lens, ISO 1600 sensitivity, Fujifilm Intelligent Flash system and multiple scene selections make it a truly take-anywhere camera. From nights out, the kids' school play or sports day, right through to countryside walks and family holidays. It's the ultimate camera for every occasion having button layout rocker zoom and mode dial, can be operated easily with one hand.
Fast and inexpensive connections over WLAN and HSDPA-enhanced 3G accelerate the mobile use of data- and transmission-rich applications. The interface to business and leisure applications and the Internet, the stunning Nokia S60 browser, with 16 million colors, is capable of displaying the full width of a web page at once. The Nokia E90 Communicator is now based on the S60 platform, making a wealth of additional mobile applications available for its users. The Nokia E90 Communicator also has an integrated GPS and Nokia Maps application to provide help in finding routes and locating services. For increased personal convenience, the Nokia E90 Communicator is equipped with an FM radio, a music player, a video player and two cameras -- a 3.2MP auto focus camera with flash and a second camera for videoconferencing.
