IMU Data Analysis: Acceleration | Live Video Sync

[@mithunsaha1981]

This is one of the best videos demonstrating IMUs in action. Really enjoyed it as it made many things clear which some other videos I watched earlier couldn't. Thanks!

extremely useful thanks!

[@couplingconstant]

Very nice device and great video! I wanted to double check that the +z axis points through the sensor, or that the device reports the acceleration in a left handed coordinate system.

Thanks for the video👍👍 very useful

[@tayebehna3613]

Hi, thanks for the video. Why isnt it a right hand coordinate?

[@iliaspatsiaouras3783]

Would be nice if you could comment on the fact why the gravity is appearing to be detected with the non expected sign. (acceleration upwards)

[@tayebehna3613]

I know that it has sth to do with the equivalence principle of Einstein.

Thanks LEOMO...a lot of thanks... One thing I need to understand from you...one is the data when you move it in a particular direction...suppose while moving in a particular direction, if it also vibrates with a particular frequency , how the data will be of the graph..basically I want to know the difference between the movement data and the vibration noise ...plz help me dude..

thank you :)

This is a fantastic explanation. Thank you for posting the video. Which software do you use to plot sensor data?

[@boligrafo4595]

Hi! I'm trying to get the gyroscope data from a smartband using GATT protocol and when I get gyro data I got it referenced to a global system (absolute position) instead of detecting changes in position. What can that mean? Thank you in advance!!

[@VikashKumar-wb2dz]

why the coordinate system used here doesn't follow the right-hand thumb rule ?

[@mariochang6335]

RHR #1: Thumb = +x Index =+y Middle = +z RHR #2: Index = +x Middle +y Thumb = +z I think it does.

What software do you use to retrieve your accelerometer data? Can this work for other IMUs?

[@badialanazi8567]

Hey There thanks for the video , I'm wondering How could you calculate g value , I'm conducting an experiment using accelerometer that shows data in three axis and would like to calculate (g) or mm/s^2 , Would you please help with the formula . Thanks

[@learnsowecanfly1124]

Can you please explain in detail why there is a negative curve when going in +x direction? And why there is a positive curve when going in -x direction? I understand that there is deceleration but does it really have to be negative curve? Sorry to bother you with these basic questions.

[@oboimert901]

Hi, I'm not that good in this but I think the reason that we've got a negative curve when going in +x direction is because our acceleration was decreasing (because when we stop the movement our acceleration becomes zero) I hope that's the question you ask and I was not misunderstood your question.

[@tintenfischfee9918]

when he starts to move the sensor in the +x direction he is accelerating it in that direction. A deceleration is an acceleration in the opposite direction of travel. So when he is decelerating you could also say he is accelerating in the -x direction.

[@Figaro623]

When sensor moved to +x direction, sensor must keep moving with constant velocity (acceleration 0) to get only positive curve . Because sensor went slow down and stopped at the end, sensor produced the negative curve values.
