I just found an article on The Question in the magazine Philosophy Now.
"Whilst the current haptic device, designed by humanoid technology engineer Adam Spiers, is a excellent step in the direction of delivering a similar theatrical experience to both blind and sighted participants, I have a sneaking suspicion that blind participants may have gained more from the experience than I."
This is an interesting point. On one hand the lack of light in the Question meant that sighted audience members were certainly deprvied of their primary navigational sense. On the other hand the familiarity of blind audience members with a lack of sight meant that the Lotus didn't always offer the same level of navigational benefits and encouragment as for sighted audience members.
The article was written by Sue Rolfe, who studied Philosophy under Martin Milligan. The plot of The Question was based on 'On Blindness' a book of letters between philosophers Bryan McGee and Martin Milligan, debating the nature of blindness with regard to one's experience and knowledge of the world.
