“Sound Objects” by Peter Vogel, (1979- present)

Precedent Analysis — priyaganadas @ 1:18 am


Electrical circuits are often messy. The artist creates a aesthetic 3D sculpture from functional electrical circuits connected to speakers. These sculptures are made interactive using piezo sensors, photo cells and microphones. The project consists of unique amalgamation of technology, form and sound.

“Self Organizing Still-Life” (SOS) by David Fried, 2007 onwards

Precedent Analysis,Uncategorized — priyaganadas @ 10:41 pm

SOS by David fried is series of kinetic sculptures / art installations. It represents how the universe is interconnected and different elements move in their own rhythm. The sculptures are activated by ambient sound. Every sphere is of different size to give “individual character” to the element. Spheres are carved out of solid rock, sand or made using synthetic polymers as explained by the artist.

The technology is not explained, but my guess is microphones are used to detect the ambient sound and possibly magnets are used in the base of the installation to trigger the movement.
I find the installation quite organic and seamless. Even though technology is used, it is not to be seen or felt in any manner. The installation replicates the movements in the real world, metaphorically.

“SKinput” by Chris Harrison, et al. HCI Institute @ CMU and Microsoft Research, 2010

Precedent Analysis — priyaganadas @ 9:47 pm

Skinput uses technique of biosensing to create an user interface where skin acts like the interface. User wears an armband which consists of acoustic sensors to sense the tapping. The device has arrays of sensors to spatially differentiate location of the tap. The software is developed to minimise errors and clearly identify individual finger movements.
This project use arrays of vibration sensors.


The idea of using skin as a user interface is novel. Project makes me realise that acoustic sensing need not be in human hearing range, microphones can be used to receive signals from any frequency range.
