Tilt Chair Iterations, Prototyping and Electronic Technology



Inspired by organic shapes from orchids.



This is Prototype  A, which works better at rocking side to side.
Prototype B – orchid design in 3d print. Direction of rocking is harder to control because of the curve at the bottom, which I thought would help with the tilting. Apparently not. Lesson learnt: lower the seating area for stability. Refer below for sketch.

New Sketch

I will draw this properly. (In a hurry for cadding)



This one tilts very well in prototype.



Inspired from sail boats arrangement

• Direction faced

• Space between chairs

Out of the sketch below, three are picked: First column 3rd sketch, Second column 2nd sketch, Third column first sketch. They are chosen because they allow the audience to enjoy the space but also see some of the audience. If the game allows tilting it can likely introduce some competition/choreograph to choose storylines.

• Number of 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)

Other components 

Power source (charging port)

Power storage battery

Controller or system amplifier

Microcontroller (MCU)

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.
