A comparison among different front-end input versions of a medical record system

This paper describes a series of experiments to test whether there are significant differences between several different versions of the intelligent medical record-entry system (IMR-E). As the costs of including color graphics decrease, the use of multimedia technologies is becoming an important issue. The development of pen computers provides a whole new range of possibilities for data input. The authors are planning to measure the effects of color, machine speed, and the use of a mouse or a pen computer on input time and user satisfaction when the system is used to input patient data by physicians and medical students
