Tracking rehabilitative progress with Fitts and starts performance measures in a tablet game for hemi-spatial neglect patients

We designed a tablet game to diagnose, train, and assess the rehabilitative progress of hemi-spatial neglect patients. We found that a set of parameters from fitting Fitts' law to hit delays in a whack-a-mole game can be used to identify neglect patients due to the asymmetry between performance on the left and right hand sides of the screen. Performance improvements were evident in in-game metrics as well as to the patients through summary screens.
