Actually, we (me and a student) have built exactly such a device this year. Did not have time to finish and evaluate it yet, however. Some papers on grasp interaction with spherical objects: Tango: www.cs.mcgill.ca/~kry/pubs/iser/iser.pdf Graspables: www.media.mit.edu/~vmb/papers/chi09.pdf Grasp Sensing for HCI (my paper, more generic): http://www.medien.ifi.lmu.de/pubdb/publications/pub/wimmer2011GRASP/wimmer2011GRASP.pdf http://www.medien.ifi.lmu.de/pubdb/publications/pub/wimmer20...
