E-Composer: Enabling the composition of mobile assistants

ELEPHANT (ELEments for Pervasive and Handheld AssistaNTs) is a system that aims to integrate a broad range of users (e.g. designers, domain experts and end users) with different backgrounds in the process of developing personal mobile assistants. In this paper we present a user study that we have conducted for two reasons: First, to screen characteristics of modeling mobile assistants by non-experts of mobile software development; and second, to test a first prototype of the ELEPHANT system's graphical modeling tool (E-Composer).
