The GReAT project aimed to develop an affordable computer-based gesture therapy called Gest to help people with severe aphasia practice gestures at home. Through participatory design sessions with people with aphasia, they created a prototype for testing in a pilot study. Preliminary results found Gest was successfully used independently in diverse home settings and enjoyed by users. However, the pilot study was still needed to determine if Gest improved gesture production or naming abilities and if effects were maintained after use.
