Mobile User-Interfaces for Text Input in Time-Critical, Unstable and Life-Threatening Situations
Simon Nestler and Gudrun Klinker
Paper based documentation sheets are still the basis for documentation and communication in mass casualty incidents. Computer assisted emergency management, however, has huge advantages in assisting rescue workers in the emergency management processes. Entering the patient’s name and first name is rather complicated because they could consist of nearly any character string. Unfortunately none of the standard input modalities can be used when taking the emergency specific requirements for mobile user interfaces into account. In emergency environments an input technique which mostly works with only one hand is required. When using hand-helds in emergencies a stylus cannot be used for various reasons. The developement of a fast and intuitive user interface for text input on the basis of the given requirements is the first step toward a mobile user interface for emergency operations.
