I'm trying to use acc and gyro data to reconstruct a human manikin of the user, have you ever tried to do something similar or do you have any suggestion?
Thanks in advance!
I've heard of some folks suggesting this, but not of anyone that has actually tried.
The first thing you would likely need is a 'sensor fusion' algorithm that can use gyro/accelerometer/magnetometer values and get a good idea about XYZ values.
Realistically you'd probably be better sending the raw sensor data from the Puck to a PC, and doing the sensor fusion there - because if you know a Puck is attached to a certain joint then those restrictions could actually help with the reliability of the data since it'll give more of a clue to where the Puck actually is.
Thank you so much! I’ll let you know more if I’ll be able to succeed. Actually we would like to integrate the bangle 2 too. Is it feasible in case to provide the Puck with a small motor for vibration alerts?
The Puck does have a 'FET' output pin which provides a higher powered output, so you could attach a (small) motor between the 3V pin and that, but the CR2032 battery doesn't provide much power. You could always add a bigger battery as well but then the whole thing starts to get quite large!
Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.
