| Abstract [eng] |
There are more then 5 billion cell phone subscriptions globally today, which is more then 5 times bigger then personal computer users. Most of the cell phones nowadays are more powerful then personal computers back to the 90s. This allows us to use cell phones not only for communication, but also as fully functional multimedia or gaming devices. Accelerometer in mobile device was introduced not so long ago with the main purpose – automatically control screen rotation based on viewing angle. Nintendo introduced a new great idea to use accelerometer data and gestures for additional user input as control. This idea can be implemented in mobile devices too, but the main problem is how to use raw, noisy, jittery accelerometer data to control something on the screen. This is the main topic of this research. The main objectives of this research is: • Accelerometer feasibility study, • Reasearch the potential of using accelerometer as controller and possible similar systems, • Create constructive and explicit method to use accelerometer as controller, and use this method to create a simple game prototype. • Perform experiment with created game prototype to research accelerometer advantages over classic controls. To achieve these objectives a requirements specification and detailed project for a software system is performed. The final method features are the following: • ability to control game object in any direction, use simple gestures, • smooth game object movement using data filters and rotation angles interpolation, • ability to calibrate accelerometer data, • speed and magnitude data. |
