Use Wii Balance Board in LabVIEW

[craya]

The function only adjusts the offset (zero calibration) and return the value of the sensors. To find weight you need add all the sensor values and adjust the ratio of the weight. The relationship tested in some boards was 102 units per kg. approximately, then to get the weight you need divide the sum of the sensors between 102 and get the weight in kg.

Ex. If the sum of the four sensors is 7742 then 7742/102 = 75.9 kg.

Ross I've just gotten hold of the published research and congratulations are due to you and your team.  I bet gait scan and Kistler are quaking in their boots and a round of discrediting will ensue... but much appreciation from one of the little guys..  please please share the code it will revolutionise rehabilitation, patient education and research opportunities..

Kudos to you all

hi, i have unzip the balance board file, but can you tell me how to run this file? do i have a project file to run this? thanks very much!

[henry Henry]

hi, can you tell me what else do i need in order to run this wii balance board file? i tried to run this file but the computer displayed some report error, like Wiimote Set Output Report.vi:13 and Wiimote Get Input Report.vi:1.

what dose that mean? and what should i do to fix this?

Thanks very much!

hi Ross, just wonder how you implement your program using the wii balance board file. is it possible that you can upload your program? thanks very much!

You need the functions developeds in this other message about Wiimote usage "Using a wiimote with LabVIEW " :

Thanks. i have downloaded both files. so what should i do next? should i run the VI file Usage_WiiBalanceBoard.vi directly or should i run other files in order to interface with the balance board? Thanks very much!

[craya]

Run  Usage_WiiBalanceBoard.vi directly. The only file that is not included in the Wii Balance Board zip file is wiimote.dll, that is included in wiimote.zip.

Be careful with the index that normally is 0.
