Dialog based testing is performed in conjunction with a three-dimensional (3D) virtual reality (VR) system including at least one loudspeaker, a microphone, and a 3D VR headset having a display for displaying 3D VR video and a gaze tracker integrated with the headset. The dialog based testing includes: rendering a 3D avatar via the display of the 3D VR headset; engaging in a dialog including causing the rendered 3D avatar to make utterances in accordance with the branching dialog script and receiving responses to the utterances from a test subject wearing the 3D VR headset including at least verbal responses received via the microphone and gaze activity recorded by the gaze tracker and traversing the branching dialog script including selecting branches of the branching dialog script based at least on the verbal responses received via the microphone; and grading the test subject based on the responses.

Dialog-based testing using avatar virtual assistant

A method for operating a vehicle having variable-speed left-side and right-side propulsion units (such as, without limitation, a tracked vehicle having a left track powered by a left-track motor and a right track powered by a right-track motor). The left-side propulsion unit is controlled by a first output signal from a first manual controller (such as, without limitation, a left joystick). The right-side propulsion unit is controlled by a second output signal from a second manual controller (such as, without limitation, a right joystick). At least one of the first and second output signals is modified to create a substantially identical output signal for the first and second manual controllers when the first and second output signals are within a predetermined tolerance. The left-side and right-side propulsion units are controlled with the identical output signal when the first and second output signals are within the predetermined tolerance.
