Lens through a Stereogram
We were asked to present Lens through a Stereogram as part of the Exploratorium at PLASA 2016. Working in collaboration with audio visual and sound companies that sponsored us their prime equipment, the installation explored different concepts around visual and auditory perception.
As we were researching into how sound and visual perception changes in dementia, the subject matter very influenced our ideas. Lens through a Stereogram thus also acted as research process for which we could create pieces that could be included or further developed for our more ambitious installation A sense of Wonder.
Ideas we explored for the pieces included
The Mirror Interface explores the notion of the self and how people with dementia might not recognise themselves when looking in the mirror.
Filming participants, the moving image runs through a programme that slowly distorts it, before being relayed back onto several LED screens that acts as the mirror interface. Images are further fragmented by randomly changing from 1 to 2 to 3 images per screen.
People with dementia often have problems with their spatial awareness. There’s been interesting studies indicating that problems in spatial awareness could be an early indicator of dementia. Recreating a couple of London Street scenes, projected over a corner participants are tracked by a kinect system that confuses their sense of location.
The podcast sound piece takes its influence by a recent study that has found that people with Front Temporal Lobe dementia find an increased enjoyment and craving in listening to music. Many other studies have also shown how music can elevate the mood and also increase cognitive ability (if only for a moment) in people with dementia.
Merging this idea with the hypothesis that people with dementia often find increased difficulty in processing semantic sound (language), participants will experience the 3D audio piece, which they will listen to through binaural headphones, as both confusing yet also calmingly relaxing.
Presenting ‘Lens through a Stereogram’ in a location that is naturally noisy, works well in correlation to the fact that environmental sounds especially when high pitched can be very distressing to people with dementia.
Recording and distorting the noisy environment at PLASA before playing it back through highly directional speakers will create a location in the art installation in which the sound perceived creates great discomfort to the listener.
The light explores how visual perception may influence the ability to read. Playing with placement, colour and a randomly flickering light the piece explores how: how words or letters often appear to move around or become superimposed over one another often creating a kind of shadow that makes it difficult to read the word; the difficulty in remembering what you have read before and as such reading the same text over and over again; the inability to decipher letters and words in the right order to form a coherent sentence.
