Interactive Pavilion Final Prototype Description

Interactive Pavilion is an interactive kinetic architecture which designed for public resting area. Our design is based on the public area in Central, Hong Kong, where is crowded by many Philippians maid in weekend. We found that the public place is not good enough for people gathering, they have to sit in one straight line and hardly face and talk to each other. They were forced to sit on the ground and gather in a circle to chat and eat. We want to make a changeable structure could serve well for individual resting area and also for friends gathering.
From this concept, we considered to make it interacts with people by the amount of the users. We assumed that we could use some sensor to detect that how many people were in that place. If there are 2-3 people, the structure would keep in one state which is good for stranger to enjoy there own resting area; if there are more than that, maybe 5-6 people, they might be knew each other and would like to enjoy there holiday there for a long time, the structure could be opened or extended to a bigger scale. For further consideration, just because the structure would be moving and changing, to avoid disturbing other people’s rest, the condition to trigger it on should be get all the users permission. So we designed it as a specific motion or something to make the structure work. Maybe it’s not convenience enough, but we thought it would be a good chance for the people to talk and interact with strangers to enhance better social interaction.

using flow

Status 1(close)

Status 2(open)

to make sure the interaction between the user and this structure nice and safe, we set several sensors around the structure.
the sensors could detect are there any peoples are inside or outside the structure, make sure that the structure will not suddenly move to frighten or hurt someone around it.
we use an easy flow chart above to tell how it works

Testing model

actually, in this kinetic structure we used only one motor to be the power source.
we used one big gear in the center with spiral track, one small gear in the motor to transfer power and four gears to make the big gear run stably.
above all the gears, there is a cover with 6 tracks to restrict the motion for the top structure.
