Title

Multimedia in public access settings : evaluation issues

Abstract

Public access systems represent a new type of multimedia computing environment that is becoming increasingly common. Examines a number of studies that evaluate public access systems spanning experiments, field tests, and prototypes. Different types of evaluations focus on different aspects of the effectiveness and impact of such systems including quality control and cost benefits. The results of these studies suggest that system designers and developers need to be more selective in the type of evaluations they conduct depending upon the purpose and nature of the public access system. There is also a need for comparative evaluation studies that involve multiple assessment techniques
