BetterSitt is designed to be fitted on any chair and to be used by anyone! The minimalist and compact design allow you to use it at any workplace - on your wooden chair at home or your ergonomic chair at your office!
Machine Learning
Machine Learning was used to predict posture of the person sitting on BetterSitt using sensor data distribution and height and weight of the person. We trained our very own model using a Random Forest Classifier by collecting over 12,000 datapoints over a variety of heights and weights. The datapoints were thus labelled with our novel automated labelling system that used the skeleton prediction model Alphapose to classify the positions. This allowed for easy collection and labelling of data to train the model, and we thus achieve an accuracy of 97% for easier to predict postures (such as whether the person’s back is supported) and an accuracy of 85% for more complex postures (such as whether the person is sitting cross legged)
