Realization with panStamp and pulse sensor

January 22, 2015 Chinh

Following the Food for “Thought” , we continued to discuss our ideas. A good thing is that the script was out, so based on it, we get a general concept of how things will be. As for technical side, panStamp and pulse sensor were chosen for the next phase

PanStamp

We need to send information from the sensor on the stage to the computer. That is where PanStamp comes in

The PanStamp battery board is our sender- read signal from the sensor and pass it to the PanStick. A bit of soldering work is done on the battery board, mainly for the mobility of using sensor- instead of fixing the sensor, we can remove it at will.

While the energy source is 1.5V AA battery, PanStamp battery board itself can amplify it to 3.3V.

The PanStick reads wireless transmission from PanStamp battery and pass it to the computer via Serial protocol.

Pulse sensor

Pulse sensor uses the principle of light-sensing in order to calculate the heartbeat. It is assumed that when the heart beats, there is some kind of shockwave throughout our body. From that perspective, the beat-per-minute (BPM) and interval -between-heartbeat(IBM) can be measured.

It was kind of a fun journey with the pulse sensor. At the beginning, the result was unstable , but after a while of tinkering, this pulse sensor does what it is supposed to do. Still, low power supply usage can be quite deceptive since the sensor “appears” to be working fine , but instead, you will need to change the code–or to wire it differently.

The guide for it can be found here: Guide for Pulse-sensor

The Pulse sensor ,in our project, shall be wired to the PanStamp battery board.

Concept for visualizing thoughts by using biometric Sensors

Background:

SAKI chose the Hide Park in his shortstory DUSK as setting for Gortsbys thoughts and allegorizes them with pictures of the inside of the character Gortsby.

Gortsby visits the park to get in contact with someone or something. A park basically is something natural, but at the same time created by humans, domesticated and influenced by peoples culture and society.

Is it the same with our thoughts?

The two different encounters and Gortsbys misjudgment (amplified by the element of the soap as a symbol of domestication) show it apparently – his thoughts are a result of society influenced prejudices.

Find out more about our research on visualization of thinking/prejudice in our thoughts video .

The Design of Domesticated Thoughts:

For the projection of Gortsbys thoughts we discussed a lot of ideas about visualizing thoughts as something industrial reproduced or metaphorical like growing thought-plants.

Finally we chose a realistic „domesticated“ point of view perspective and Close Up videos of nature and contrast them with the destruction and irrationality of animated abstract forms. This visual process from a naturalistic picture to abstract forms we want to effect interactively via biometric input of the actor in our play.

Realisation:

Biometric Input via Voice and Heartbeat Sensor:

We influence the visual process through biometric parameters of the actor like voice and heartbeat. Associative pictures are build up and fall apart triggered by the actors behavior.

The transformation from biometric input into projected output refers to the ambiguity between nature and domestication and is a connecting piece between actor and stage.

The sense of sensors

Tilt Sensor

A tilt sensor can measure the tilting in often two axes of a reference plane in two axes. In contrast, a full motion would use at least three axes and often additional sensors. One way to measure tilt angle with reference to the earths ground plane, is to use an accelerometer. (Source: Wikipedia)

Accelerometer & Gyroscope

An accelerometer is a device that measures proper acceleration (“g-force”). Proper acceleration is not the same as coordinate acceleration (rate of change of velocity). For example, an accelerometer at rest on the surface of the Earth will measure an acceleration g= 9.81 m/s² straight upwards. (Source: Wikipedia)

A gyroscope (from Greek γῦρος gûros, “circle” and σκοπέω skopéō, “to look”) is a device for measuring or maintaining orientation, based on the principles of angular momentum. Mechanical gyroscopes typically comprise a spinning wheel or disc in which the axle is free to assume any orientation. (Source: Wikipedia)

Photo sensor

A photoelectric sensor, or photo eye, is a device used to detect the distance, absence, or presence of an object by using a light transmitter, often infrared, and a photoelectric receiver. They are used extensively in industrial manufacturing.

Tutorial

Motion sensor

A motion detector is a device that detects moving objects, particularly people. A motion detector is often integrated as a component of a system that automatically performs a task or alerts a user of motion in an area. (Source: Wikipedia)

Pressure sensor

A pressure sensor measures pressure, typically of gases or liquids. Pressure is an expression of the force required to stop a fluid from expanding, and is usually stated in terms of force per unit area. A pressure sensor usually acts as a transducer; it generates a signal as a function of the pressure imposed. For the purposes of this article, such a signal is electrical. (Source: Wikipedia)
