Stefania Serafin just held a great lecture on multimodal perception and sonic interaction design at the SMC summer school. It is fascinating with the differences in spatiotemporal resolution between the different senses:

Spatial resolution

1. eye
2. tactile
3. ear

Temporal resolution

1. ear
2. tactile
3. eye

Stefania showed a number of examples of the application of this knowledge in interaction design, one example being the tactile floor they are building at McGill.
