Do modern notebooks still have vibration sensors? I think old ones had them in the hard drives, to protect them from damage. But SSDs wouldn't need that anymore

Do modern notebooks still have vibration sensors? I think old ones had them in the hard drives, to protect them from damage. But SSDs wouldn't need that anymore.
In any case, I wonder if detecting vibrations and recognizing the boss via machine learning wouldn't be more elegant.
- jaifraic 7y agoWell, gait is usable as a biometric identifier. While most approaches use video analysis, I found this a paper [1] that is about identifying people through footstep induced structural vibration using a geophone[2]. It would be quite interesting if it is possible to measure the structural vibration using a laptops or smartphones built in accelerometers. But I think acoustic sensors would be a better way. Or a combination of both options.
- suhlig 7y agoInteresting - can you provide [1] and [2] please?

- cwkoss 7y agowebcam vibration changing the field of view could be a decent proxy for laptops.
