Design and Implementation of a smart chair system for IoT

We present the design and implementation of a Smart IoT Chair system for Internet of Things (IoT) that combines an embedded IoT device and a chair with separated seating pads. The proposed Smart IoT Chair records and visualizes user's posture through a smartphone application to help the users correct their unbalanced posture. It uses custom designed sensors for pressure and tilt sensing, and also uses iBeacon and Bluetooth communication to transmit data with low-power consumption. We implemented a prototype of Smart IoT chair combining six custom sensors, an Arduino, a Bluetooth module and a chair. Preliminary results show that our Smart IoT Chair combined with our case-study smartphone application can accurately detect various user postures.
