Want to be able to calculate your BMI via WiimoteLib so you can use your board ala WiiFit, heres how its done:

The formula for calculating BMI is a simple one and can be defined as follows:

BMI = Weight in kilograms / height in meters² – Metric
BMI = (weight in pounds * 703 ) / height in inches² – Imperial

The following function is passed a WiimoteState value ws and returns BMI as a double. The division by 100 is used to convert a cm user_height value into meters and can quite easily be replaced/removed if desired. Read..

Today is a good day. After a exactly one year and two days, I have finally cracked the enigma of Balance Board Orientation, and have a version which robust enough for release.

Needless to say I am overjoyed, check out the video:

During the last year I have developed numerous implementations for the task, most of which worked, however none strong enough to deal with the heterogeneous error known as untrained users, however no more!

I am now working on implementing the system fully within both WiimoteLib and the WiiCi driver. Check back soon for more details.
