A preliminary usability study is presented and the data respiting from the preliminary study are analysed and discussed. Efficiency in terms of response time due to network delays, database processing, application processing and image characteristics and display is discussed. Response time results from 40 queries made to the image database are presented and discussed. The results of these studies demonstrate where improvements in the system need to be made in order to improve usability and response time.
