2. Figure out how the growth process (longer sitting time)

3. Make a diagram of the movement in the field

Developing Progress

2010-03-08T04:59:00.000-08:00

The Input System
A sensor that can monitor the breathing of the user(s) accurately without attaching anything to the user.

Proposed Solution:(1)babysense[Respiratory Movement Monitors] (2)a non-contact breathing sensors

Interaction and User Behavior
Define the level of interaction that the design can engage people with the architecture.

Proposed Solution:(1)interactive ceiling (2)interactive chair

Masks Wearing Phenomenon
Re-examine weather people wearing mask is a hurdle to our goal of the design.

Proposed Solution: air purification system

SENSOR RESEARCH

A NON CONTACT BREATHING SENSORS
using microwave sensors attached to the ceiling sensors for sensing breathing and heartbeat

video, ref1, ref2

BABYSENSE
(non contact commercial breathing monitor for baby £74.95)
The Babysense II alerts you with an alarm if your baby's breathing becomes abnormally slow, abnormally fast - or if breathing and motion stop completely. It is certified as a medical device and is extremely simple to use.

CAPNOGRAPHY SENSOR
low-cost small-size, low-power carbon dioxide sensor.

HEARTBEAT SENSOR

MEASURE AND MONITOR HEARTBEAT RATE

be clipped to finger ends or ear lobes to detect the heartbeat

OPTICAL FIBRE SENSORS
A nanostructured optical fibre-based thin film sensor was designed for non-invasive, fast and reliable monitoring of respiratory airflow.

TENTACLE RESEARCH

Optical Fiber Optics

possible solution for tentacle (tentative)

CHAIR & ENVIRONMENT RESEARCH

The system should support not only individual waiting

but also group communication.

Inspiration from the structure of honeycomb

KEYWORD FEEDBACK :

1. turn the world upside down

2. keep the room rectangle but 3D sculpt the ceiling

3. no interactive chair

4. do more research for the tentacle movement

stressful place in hospital waiting room

P R O P O S E D _ S O L U T I O N

This project nourishes interaction between

an interactive interior installation and people's activity

in a hospital waiting room.

A field of long thin fibers(tentacle) with a metal piece on its tip

that hang on the ceiling will give real-time response driven by

a sensor embedded in the chair that measure the user's breathing rate

also the duration of their sitting time.

Different breathing pattern would lead

different form of motion created in the tentacle field

and the sitting time alter the growth of tentacles downwards slowly,

if more user comes into play, the field would turn the whole ceiling alive

by slow swinging the tentacles.

The environment help user to take away their stressfulness

of waiting in the hospital by engaging them into the relationship

of the moving tentacles and their breathing rate.

ABSTRACT CONCEPT

cloud

⠶

wind ⠶ sand

Although some breaths may be deeper or faster than others,

when we're relaxed, the alternating rhythm of the inhalations

and exhalations feels like a lullaby

—smooth, soft, and uninterrupted by jerks and jags.

Consciously relaxing into this wavelike,

oceanic quality of the breath deepens our sense of peace and ease.

T E C H N O L O G Y

An electromagnet is a type of magnet whose magnetic field

is produced by the flow of electric current.

The magnetic field disappears when the current ceases.

{wikipedia}

Two directional bi-flex sensors

A unique component that changes resistance when bent.
An un-flexed sensor has a nominal resistance of 10,000 ohms (10 K).
As the flex sensor is bent in either direction the resistance gradually
decreases.Sensor is also pressure sensitive, and may be used as a force
or pressure sensor.
