Inspired by organic shapes from orchids.
This one tilts very well in prototype.
Inspired from sail boats arrangement
• Direction faced
• Space between chairs
Choice of technology: Tilt Sensor
Goal: To measure the angle of tilting as the sitter tilts (analogue to digital) – IF the seat tilts towards right, MCU will process the command and through wireless net, send it to the server.
Load Sensor (Input) on both sides of the chair.
• Strain gauge/Pressure Switch/Load Cells
• Active sensors require external power source
• Analogue (Output changes continuously over time)
Power source (charging port)
Power storage battery
Controller or system amplifier
Wifi DLNA, Wi-Fi Direct with P2P-Client, and P2P-GO
Cloud services support to assist in the development of cloud-based applications for use with the IoT.
