SUMMARY:Communicating with buttons: current progress in one- and two-butto

DESCRIPTION:The paper \\\\\\'Effective Communication with one or two butto
 ns\\\\\\' (MacKay\,Ball & Donegan\, 2004) describes how Dasher could be dr
 iven by discrete button  pushes rather than continuous movements in two di
 rections.  One of the prototypes discussed has already been implemented: a
  two-button menu version of Dasher in which each button push corresponds t
 o either a cycling between or a choosing of different zooming options.  Th
 e preliminary results of the first round of novice training sessions will 
 be presented and human performance compared to the optimum performance rat
 es predicted by information theory.  Another prototype suggested by the pa
 per is a time-critical\, one-button mode.  A preliminary investigation int
 o the operational parameters that would need to be incorporated into such 
 modes is discussed.\n\nThe original paper\, \\\\\\'Effective Communication
