Abstract: Various embodiments of systems and methods to assess gesture inputs for performing usability testing of an application are described herein. In one aspect, a GUI associated with an application to be tested is presented. Gesture inputs from test participants to invoke execution of a task of the application using the GUI are recorded. Further, 3D coordinates corresponding to each of the recorded gesture inputs are determined And, the determined 3D coordinates are assessed to determine at least one intuitive gesture input to invoke execution of the task of the application.
