Scott Smallwood came to talk to our interactives group about his work on musical instruments. Scott was involved with the Princeton Laptop Orchestra (PLOrk) and demonstrated one of the hemispherical speakers that they designed so that laptop musicians could join and play with others. The idea was that a laptop musician, instead of plugging into a sound system (PA), should be able to make sound from where they are just like the analogue instruments. I wonder what the visualization equivalent is? Will these new pocket projectors we can begin to imagine visualization instrument that are portable. Pattie Maes and Pranav Mistry’s demo of SixthSense at TED is an example of creative thinking about outdoor interface.
