2.6 Preparation for Accurate Load Measurement
[Required]
Immediately before performing an accurate weight measurement (for example, in order to display the
weight), always display a message that prompts the user to step off of the Wii Balance Board
accessory.
Next, do the following.
1. Call the WBCRead function to confirm that the user has stepped off of the Wii Balance Board
accessory.
2. Execute the temperature update command to set the zero point and to correct the weight value.
3.
Display a message that prompts the user to step onto the Wii Balance Board accessory.
For details, see the Function Reference Manual.
2.7 Time Required for Accurate Load Measurement
[Required]
When precisely measuring a load (for example, in order to display a weight), allow two seconds
respectively for zero-point correction and for load measurement.
The accuracy of the Wii Balance Board accessory measurement is guaranteed by taking the average
value over two seconds.
2.8 Time Restrictions for Accurate Load Measurement
[Required]
When precisely measuring a load (for example, in order to display a weight), prompt the user to take
the measurement within 10 seconds of the zero-point correction that immediately precedes it.
If 10 seconds have passed, either cancel the measurement or repeat the measurement process.
2.9 Use of the HOME Menu with Wii Balance Board Accessory Support
[Required]
Use the HOME Menu that supports the Wii Balance Board accessory.
2.10 Processing for Insufficient Remaining Battery Power
[Required]
When the remaining battery power obtained with the
WBCGetBatteryLevel
function is
0
, prompt the
user to replace the batteries.
Specifically, display the message “Replace the Wii Balance Board batteries” on the screen and do not
continue until the user has replaced the batteries.
Check the remaining battery power during each frame. The reason for this is that the
WPADRead
function will always return a value of 0 for
press
when the remaining battery power obtained by the
WBCGetBatteryLevel
function becomes 0, and Wii Balance Board operations will become impossible.
