Patent ID: 8827909

Claim:
An apparatus comprising: an ultrasound probe comprising: a body terminating at a nose; an ultrasound transducer adjacent the nose and facing in a first direction; and a first touchpad zone to detect a sliding gesture of a first digit, the first touchpad zone extending along a first surface facing in a second direction perpendicular to the first direction; a second touchpad zone to detect a sliding gesture of a second digit, the second touchpad zone extending along a second surface facing a third direction perpendicular to the first direction and perpendicular to the second direction; and a controller to receive sensed signals from the first touchpad zone in response to detection of the sliding gesture of the first digit and to receive sensed signals from the second touchpad zone in response to detection of the sliding gesture of the second digit, wherein the controller is configured to generate first control signals in response to a detected sliding motion of the first digit across the first touchpad zone and to generate second control signals in response to a detected sliding motion of the second digit across the second touchpad zone.
