Interaction - Bachelors
[Dis]connected— is an interactive art installation that fosters meaningful connection between users, and their humanity.
Inspired by the disconnection often felt by social media users as a consequence of carefully curated and inauthentic digital personas, [Dis]connected— represents a physical manifestation of an Instagram profile.
Combining custom audio-reactivity equipment with projection mapping software, [Dis]connected— provides users with an atmospheric, deeply personal, and introspective experience.
Social media has quickly become the nexus for online connection, allowing millions to interact with loved ones, acquaintances, and strangers near, and far through the creation and meticulous curation of digital personas. However, as the digital landscape continues to unfold, anecdotal and empirical evidence highlight detrimental effects associated with excess online connectivity, increased perceptibility, and inauthentic interactions. Negative behaviours and thought-patterns such as self-comparison and a fear of missing out (FOMO) are commonly linked to decreased psychological well-being, with many left feeling dissatisfied with their lives. As such, social media serves to unintentionally disconnect us from ourselves, others, and the world around us.
The Stethoscope Microphone works by amplifying heartbeat sounds via the stethoscope chest-piece. When placed on a person’s chest, the stethoscope diaphragm captures sound waves emitted from the body. These vibrations travel through the stethoscope tube and are received directly into the microphone. From here, the live heartbeat signal is detected by the field recorder and amplified.
The Stethoscope Microphone was created using a combination of medical and technological equipment, and recycled materials.
Equipment:
– Stethoscope (detached from earpiece)
– Takstar CM–63 Small–Diaphragm Stereo Condenser Microphone
– XLR Cable (1.8 metres)
– Zoom H4 Essential Handy Recorder
Recycled Materials:
– Connector Piece (retrieved from a recycled spray bottle nozzle. Cut to size and subsequently used as the connector piece between the microphone head and stethoscope tubing)
– Microphone Foam Cover (retrieved from a recycled headrest)
– Microphone Soundproofing Container (retrieved from a recycled plastic tube)
Heartbeats operate at very low vibrational frequencies (approximately between 10–20 decibels [dB]). This is equivalent to the sound of a soft whisper, or rustling leaves. Comparatively, human voices when spoken during normal conversation have a range between 60–70 dB.
Because of this disparity, and given the context of use, the Stethoscope is susceptible to capturing ambient noise, such as indistinct conversations, or handling noise.
However, integrating a foam microphone cover and tubular microphone container has soundproofed the Stethoscope Microphone to a significant degree, and has allowed for a clearer detection and amplification of heartbeat sounds.
TouchDesigner was used to create audio-reactive visuals and perform projection mapping. Incorporating in-built Audio Analysis software with a range of Channel Operators (CHOPs) and Texture Operators (TOPs), live heartbeat signal input was converted from a sound frequency, and into a switch that would alter the video output when a specific trigger threshold was met. Many of these operators contain custom Python expressions within specific parameter settings to achieve optimal audio-reactivity and desired output.
