Stress Makes Art: Galvanic Skin Response and Visual Generation

I'm interested in connecting the signals generated by one's body to the act of visual generation. This piece takes the galvanic skin response value of the user and uses it to fuel the creation of a visual on screen. Galvanic skin response is thought to be correlated to a person's stress level and is used in lie detectors. In this particular work, the GSR value affects the speed at which a black growth is visualized on screen. Homebrew Arduino Pulse Monitor (Visualize Your Heartbeat) - 7. Homebrew Arduino Pulse Monitor (Visualize Your Heartbeat) Movies look cool with those EKG (electrocardiogram), the one that beeps and detects heart activities.

Homebrew Arduino Pulse Monitor (Visualize Your Heartbeat)

A few months ago, we had to shoot a hospital scene for our school project. We needed an EKG instrument. To keep the movie authentic, we didn't want to fake the readings so we made the next best thing, a pulse monitor. Since my dad is a doctor he gave me some advice to design the pulse monitor. Let me clarify this to you. Arduino KY-039 Detect the heartbeat module - TkkrLab. Buy this sensor or kit.

Arduino KY-039 Detect the heartbeat module - TkkrLab

This project uses bright infrared (IR) LED and a phototransistor to detect the pulse of the finger, a red LED flashes with each pulse. Pulse monitor works as follows: The LED is the light side of the finger, and phototransistor on the other side of the finger, phototransistor used to obtain the flux emitted, when the blood pressure pulse by the finger when the resistance of the photo transistor will be slightly changed. The project's schematic circuit as shown, We chose a very high resistance resistor R1, because most of the light through the finger is absorbed, it is desirable that the phototransistor is sensitive enough.

Resistance can be selected by experiment to get the best results. Pulse Sensor - SEN-11574. Galvanic Skin Response Sensor. Galvanic skin response readings are simply the measurement of electrical resistance through the body.

Two leads are attached to two fingertips. One lead sends current while the other measures the difference. This setup measures GSR every 50 milliseconds. Each reading is graphed, while peaks are highlighted and an average is calculated to smooth out the values. A baseline reading is taken for 10 seconds if the readings go flat (fingers removed from leads). Galvanic Skin Response using Arduino UNO. Module Grove Réponse Galvanique de la Peau.

Easily Take a Pulse with a Infrared Pulse Sensor. Taking your pulse is as simple as holding a finger to your neck or wrist and timing the beats with your watch.

But if you want to record the data or use it to trigger events, you need to turn that mechanical pulsing action into an electrical signal. This pulse sensor fits over a fingertip and uses the amount of infrared light reflected by the blood circulating inside to do just that.
