Title: The relative importance of visual, auditory, and haptic information and identification of perceptual attributes of the user’s experience of mechanical switches.

Abstract: While the use of hand tools and other everyday manually controlled devices is naturally accompanied by multisensory feedback, the deployment of fully multimodal virtual interfaces requires that haptic, acoustic, and visual cues be synthesized. The complexity and character of this synthesis will depend on a thorough understanding of the multimodal perceptual experience, including the interrelations between the individual sensory channels during manual interaction. The results of two studies will be reported. In the first 70 participants were asked to rank the manual operation of ten electromechanical switches according to preference. In the second study the Repertory Grid Technique was used to identify the perceptual attributes of the user’s experience of the switches use in the first study. A between subject design was used in both studies to assess seven sensory presentation conditions. These conditions comprised six bimodal and unimodal sensory combinations created by selectively restricting the flow of haptic, auditory and visual information, plus one condition in which full sensory information was available. In both experiments PCA analyses suggest that the primary dimension is related to the haptic channel and the magnitude of feedback. The second dimension is related to those conditions in which the haptic cues were impeded and the quality of the feedback in those channels.

Haptic devices can take many forms and operate from different principles. Some of these devices can be very simple indeed, but to be effective they must always be respectful of the haptic sense in the same way acoustic transducers must be designed as a function of the sense of hearing. The presentation will cover some recent advances in the design of haptic interfaces and discoveries about the haptic sense that were made possible by these new designs.

Title: One pushes, all hear: Sonic Interaction Design is Social

Having absorbed the fashion of ubiquitous projections (of images on
screens, of sounds in space), having experienced the trend of
gestures-in-air followed by the tide of gestures-on-surfaces, we
register a steadily increasing interest into the objecthood of
everyday things and environments.
Interaction with many everyday objects is largely tactile and
kinesthetic, inherently intimate and almost inscrutable. However,
sound can make the qualities of interaction manifest and sharable.
Sonic Interaction Design is about the qualities of objects in use,
where sound is the principal mediator between human and object, as
well as between humans through the object. The design practices that
are being explored in Sonic Interaction Design are, therefore,
intrinsically social, based on sharing experiences of creation,
manipulation, performance, interpretation, and understanding.
