@rwaldron +1 completely agree with you and I tried to explain that `'samplingFrequency'` cannot be reliably guaranteed neither on platform, nor on HW level. @rwaldron There are use-cases when effective output rate of the sensor might need to be higher than 'reportingFrequency'. For example data is updated at 240Hz, while VR or game content is rendered at 60Hz. This will reduce latency for data provided by inertial sensors. What do you think about simplifying that concept for web developers by providing `'low latency'` flag? Spec can demand minimum oversampling rate. > Basically, what I'm saying is I've never heard this terminology used in the context of MEMS sensors. That's why I don't think it's a good fit. @tobie There should be [publications](http://www.nxp.com/assets/documents/data/en/application-notes/AN4075.pdf) / [papers](https://link.springer.com/chapter/10.1007/978-3-642-31494-0_14) and many inertial sensors actually work that way. I agree that we should avoid increasing cognitive load and simplify that concept for web developers, thus, I think 'low-latency' flag might be a good start. -- GitHub Notification of comment by alexshalamov Please view or discuss this issue at https://github.com/w3c/sensors/issues/209#issuecomment-305691107 using your GitHub account
