Project Recap No. 4 - Snakeskin (a Tactile Interface)...

An almost eleven meter long, Rapid Manufactured, strip of the Snakeskin (panoramic image from our nous Gallery exhibition in London)...


The Snakeskin provides a, somewhat Braille or Moon type like, touch based method and language for how to communicate things about the users surroundings and to prompt actions he or she might wish to take. The design is predominantly 'read' through running ones hand across the wall mounted relief patterns, but it can occasionally also be used and adapted as a floor based texture.

A rougly five meter section of the Snakeskin displayed at the la fontaine Gallery in Bahrain in November - December, 2008.


The design has five main components in its repertoire.

Tactile Spine
The central raised spine which provides the user, through a set of Tactile Icons (which are a set of tactile graphics that provide a form of short-hand through which to communicate a message), with a more literal note of information, such as approaching left or right turn, speed up or slow down, stop, etc.

Handscape
The scaled area on each side (top and bottom) of the Tactile Spine. This surface amplifies the message communicated by the Tactile Spine by modifying the textural qualities of the scale patterns provide a more intuitive reading of the information. For example, if one wishes the user to slow down or even to stop one can, by gradually raising the scale pattern (which are directional - smoother to touch in the intended direction of motion) increase the friction of the hand on the scale pattern and thus 'suggest' that slowing down might be a option worth considering. This action can obviously be reversed by smoothing out and elongating the scales if one wishes the user to speed up (along, say, a long corridor with nothing noteworthy to experience). More asymmetrical applications of the scale pattern can also be used to suggest various other actions or features...

Clicks
Are a regular pattern at the top side of the Handscape that provide a set metric means to distinguish the distance covered (highlighted in red).

Quivers
Occupy the bottom flank of the Handscape (highlighted in red in the image below). They provide a bespoke pattern specific to one location or demarcation. For example, each department or wing of a building can have its own Quiver pattern.

InfoIntro
Provides a abbreviated summary of upcoming features along a specific segment of the Snakeskin. It is always at the beginning of a stretch of Snakeskin and acts as a tactile rendition of the tube map (of sorts)...

All of the aforementioned elements work in conjunction to convey its tactile (haptic) message, and, as a more accurate sense than vision (see this recent NYT article for some interesting facts), the richness of nuances that can be used in creating such messages seem almost infinite...

The design also used some of the same haptic interface tools mentioned in previous posts.

A different example of a 'Quiver'...


The design was fabricated through Rapid Manufacturing, a form of three-dimensional printing (the only realistic way to make something as infinitely variable as this design), and, in the almost eleven meter long piece of the design which was made as a part of our research, we would like to cautiously claim it to be amongst the biggest ever pieces realized through these additive CAD-CAM methods.

This design would not have been possible without the invaluable help of Loughborough University's Rapid Manufacturing Research Group (RMRG), one of the foremost centres involved with related research.

The Snakeskin has been exhibited at the nous Gallery in London, the la fontaine Centre of contemporary Art in Bahrain and the Dar al-Funoon Gallery in Kuwait.

The Snakeskin is always perceived whilst in motion...
