The LiLiPUT prototype: a wearable lab environment for user tests of mobile telecommunication applications

ABSTRACT

User trials for future mobile telecommunication applications inherently pose several particular challenges which are difficult to meet in a traditional lab environment. In this paper we describe LiLiPUT (Lightweight Lab Equipment for Portable User Testing in Telecom-munications), a highly flexible wearable test system which has been realized as a fully operational prototype at the Telecommunications Research Center Vienna (ftw.). Then we illustrate how we use LiLiPUT for testing various types of mobile application in the wild.
