PDAs Comes Closer And Friendlier With Touchscreen Technology
By Busy Door Guest Blogger | October 5, 2009
Touch screen technology is being introduced into Portable Digital Assistants (PDAs). This has become fashionable as it now becomes easier to operate the PDAs. A touch with a finger or a stylus on the display area of the touchscreen is detected instantly by the PDAs. The function displayed on the point of touch gets activated. There is actually no need of an intermediary as the stylus as the finger itself is enough. The display area of the touchscreen becomes the interface between the operator and the device. This makes the conventional mouse or a touchpad redundant as these are replaced by the display and the touch. Touchscreen technology was developed during the 1960s. It was used in a computer assisted learning terminal in 1972. The HP-150 launched in 1983 was one of the first commercial touchscreen computers. Touchscreen technology has further evolved into multipoint touchscreen where the touchscreen responds to more than one finger at a time. This made it possible for more than one person to interact at the same time with the touchscreen.
The kiosk systems were one of the first to pick up the touchscreen technology. Kiosks are making their appearance in a variety of places for a variety of purpose. They can be spotted in retail stores, ATMs, tourist settings, train stations and airports. The technology has also been adapted for use in automobiles, airplanes, gaming consoles, machine control systems, appliances and various hand display devices. It finds applications in industrial automation and room automation. It is also becoming a favorite with mobile phones as, for instance, the iPhone and Nintendo DS. Touchscreen is becoming widely used and popular with smartphones, portable game consoles, PDAs and the information appliances.
Variety of models with newer features and in sleek designs is introduced into the rapidly expanding PDA market. The models available in the market include the PalmOne M515, Palm TX, Palm Z22 Handheld PDA, Pharos 535e Traveler, HP iPAQ 111 Classic Handheld, Palm TX Handheld, Palm Tungsten E2 Handheld and Nokia N810 Portable Internet Tablet.
PDAs have demonstrated their potential for absorbing newer technologies and extending its functionality. Expanding markets and technological advancement have brought the cost of PDAs down. PDAs have become more user-friendly that it can be operated by those who do not have much computer knowledge.
