A color-coded Overlay is installed on the Ultrasound 2 keyboard. It was designed to facilitate remote guidance during experiments. In remote guidance, a sonographer views real-time ultrasound images on the ground and directs (via privatized voice loops) the in flight crewmember-scanner on how to adjust the placement of the probe to improve the image, which keys to press in order to maximize image quality, and which images to store for later analysis. This method significantly reduces preflight crew training time and, at the same time, produces better images for experiment or medical use. Addition of the keyboard overlay allows crew members to navigate the keyboard with greater ease and efficiency, as well as ensures proper execution of procedures and prevents loss of data.
