Abstract
A critical issue when designing a new ultrasound system is the design of the QWERTY keyboard, which is incorporated into the ultrasound console. The introduction by Acuson of a new system with improved imaging capabilities and an emphasis on the close proximity of frequently used controls was well-received by users. However, as part of Acuson's interest in continuous improvement of the user interface, feedback from field staff identified the QWERTY as having potential for improvement. This paper describes the issues explored in redesigning the QWERTY, an evaluation study to assess the benefits of potential redesign solutions, and the eventual solution implemented. Anecdotal evidence from our customers and field staff indicate a very positive response to the new QWERTY.
