According to Ralph Hill [1], 'Buxton and Myers [2] have demonstrated the value
of two-handed, or concurrent, input in real world tasks'. Hill goes on
to describe a UIMS which 'supports the implementation of user interfaces
where the user is free to manipulate multiple input devices and perform
several (possibly related) tasks concurrently.'

Synchronisation in Human-Computer Interaction -- The Sassafras UIMS, ACM

I've only read [1], not [2], so can't comment on it. The work's been done,
though, folks!
