Provided is an automotive diagnostic tool including a tool body and a first projector connected to the tool body. The first projector is configured to project a diagnostic display image onto an adjacent surface separate from the tool body. An input detection sensor is connected to the tool body and is configured to detect motions of a user within a field of view proximate the tool body, and to generate an input signal responsive to the detected motions. A diagnostic processing unit is disposed within the tool body and is connected to the first projector and the input detection sensor for receiving the input signal therefrom. The diagnostic processing unit is configured to be operatively connectable with the onboard vehicle computer to receive vehicle data therefrom and to process the data and modify the diagnostic display image according to the received vehicle data and the input signal.
