Project Description

Healthcare solutions for back pains that do not require intervention are limited to visits to physiotherapists. This limits the extent to which the physiotherapy can aid the patients in recovering, results in patients having to go frequently to the clinic and is a waste of resources on both sides.

Our project aims to make the process of back injury recovery more efficient, as well as encourage lifestyle habits that prevent reoccurrence.

Sit Healthier, Sit Better.

Back pain is one of the most common ailments especially amongst people who sit for long hours. This phenomenon can be even be exacerbated by the current pandemic situation in which most workers are working from home.

BetterSitt is a smart and seamless addition to any workstation setup. It helps track sitting habits and cultivate better sitting habits of frequent position changes and stretching breaks.

Anyone. Anytime. Anywhere.

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!

Portable and Comfortable

Bamboo Jersey Fabric Casing

Super soft, lightweight and cooling. The perfect material for hot and humid Singapore. It also comes in a wide variety of colors and patterns.

Collapsible for Easy Transport

Our specially designed ratchet makes BetterSitt easy to fold and roll so it can be easily packed into any bag and brought anywhere

Polyurethane Foam

Thin and low-density for a breathable body that does not get in the way of the ergonomics of your chair.

No cameras used to detech posture, 11 pressure sensors are all you need!

These embedded pressure sensors allow accurate posture and sitting habit sensing and data collection without invading your privary and personal space.

Distraction-Free Reminders

Haptic feedback allows for distraction free reminders, Embedded with a vibration motor, our product will remind you to change your posture or stand up to take a break from time to time!

No more checking phone during a focused work session! Let your creativity flow without worrying how your posture is!

Long Lasting

Long battery life of more than 7 hours to ensure that your posture will always be taken care of in every sitting!

BettErgo App: Personal Ergonomics at your Fingertips

Intelligent Tracking of Postures

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)
