subject: J2me Accelerometer: Affording An Advanced User Control Interface [print this page] These days a lot of ultramodern devices such as smartphones and iTouch have appeared in the market. These devices have brought about a huge change in the lifestyle of the users. The entertainment industry specially has undergone a sea change with advent of these smart devices. Now entertainment multimedia applications are developed at a global scale for these devices. And developing such applications for these mobile devices require a different approach technically taking into consideration that these devices come with multi-touch screen and advanced feature such as accelerometer. The accelerometers integrated with iTouch and smartphones such as iPhone and BlackBerry are designed to give more control to the user interfaces. This tool tracks the tilt or the movement of the device and changes the display accordingly. For example, iTouch accelerometer changes the display from portrait to landscape and vice versa when the user tilts the device.
An accelerometer as such gives users an enhanced and convenient experience while using various multimedia applications. Whether you are watching a clip or playing a game, the accelerometer changes the display to give you more control and enhanced experience. There are different types of accelerometer for different devices. J2ME accelerometer is quite popular as many phones uses and supports J2ME applications. J2ME applications are platform independent and hence J2ME has turned out to be the most accepted framework for mobile phone applications development. Moreover, the impeccable security of J2ME apps has this framework a hit among phone manufacturers and programmers. And while developing these applications, the developers ensure the applications are made compatible and optimized for the accelerometer. Without being optimized for the accelerometer the smartphones application would not have been so popular with the users. It simply allows a user to make the most out of the application.
With newer smartphones, the accelerometer has become more effective in terms of speed and performance. And with 3G coming into picture, the role of accelerometer has become even more significant in enhancing users experience in using 3G applications such as games and maps. The iPhone 3G accelerometer is geared toward offering such experience to users.
