top | item 8568509 Ask HN: How can Google Fit tell if I am cycling? 4 points| hakann | 11 years ago It did miss a couple cycling sessions but it is mostly accurate. Does it combine the data from GPS and the accelerometer? Are these always on? 3 comments order hn newest radq|11 years ago I did a project along these times some time back, training a Hidden Markov Model on accelerometer + gyroscope data sampled every 100ms gave basically 100% classification accuracy. Can share the code with you if you are interested. fprotthetarball|11 years ago I'm having the opposite problem. I don't use a bicycle, but Google Fit thinks I do. I assume it's confusing my driving with biking, somehow. glimcat|11 years ago It's easyish to derive to good accuracy from the accelerometer signal alone (which I believe is always available).
