Levelling, drilling and other applications for measuring with a wii controller
Through several examples from university professors and software developers, the wiimote still remains the preferred device for every kind of accelerometer-based applications which require an evaluation of body/motor states(as identification of vertical level, drilling conditions or gesture recognition). In a steady state, a tri-axial accelerometer provides an angular measure compared with gravity. Then, the transient states allow the detection of changing behaviors. And finally, the maintained states (i.e. a repetitive behavior) can be identified and characterized inside a defined bandwidth of the wiimote's acquisition.
1. Measuring angular values in a stationary state
Here, the wiimote doesn't move and delivers information as a level.

| LevelTool | Wiimote as a Level The wiimote is used as a protractor (angle value compared with gravity) with the application Leveltool. Roll and pitch are displayed on a graph. This application is not complex but who really needs an overengineered electronic plumb-line.

The detection of a change in the behavior of actuators/motors/transmissions is often necessary to prevent failures and efficiency losses :

| Drilling Lab | Drilling Lab – A Sensor and Computation Grid Enabled Engineering Model for Drilling Vibration Research Louisiana State University, Society of Petroleum Engineers This application makes a comparison between a physical analog model and a simulated earth models. Drilling dynamic dysfunction and inefficient motion phenomenons are identified through a sensor platform. Cactus drilling application toolkit works with acquisition of accelerometer values (here, wii remote) via Labview as software data acquisition.
