In April 2005, Steven Wall and Stephen Brewster ran a workshop at the ACM CHI conference on haptic design and prototyping. The aim of the workshop was to attract a diverse range of developers, practitioners, and end users from academia and industry to brainstorm and develop novel ways in which haptic devices might be employed at the user interface, in such a way as to exploit the unique affordances offered by our sense of touch. The workshop was a great success, attracting participants from UK, Europe, USA and Canada.
This exhibition explored all aspects of touch and brought together artists and scientists. We ran an experiment on tactile perception, investigating the interaction between the duration of a Tacton (tactile icon) and its roughness (via amplitude modulation). Lorna Brown's work on the parameters of tactile perception showed that amplitude modulation was a key way of simulating roughness, but we did not know how long the stimuli needed to be to allow people to detect it reliably. Our study presented people with sets of two stimuli with the same length but different roughness to see what they could detect. We varied duration and the amount of amplitude modulation between the sets of stimuli.We are presently analysing the results we obtained.
Here is a photo of the exhibit, the left hand side had buttons and a games controller that allowed visitors to feel the different types of tactile feedback from current buttons and switches. The central part of the display allowed them to take part in the experiment and choose the different stimuli (presented by the purple EAI C2 tactor in the centre) using the coloured buttons. The red button on the right allowed them to feel a range of different complete Tactons.
Mark Dunlop and Stephen Brewster organised MobileHCI 2004 on 13-16 September 2004 in Glasgow.
