Development of Indices for User Perceptions of Interactive Technologies in Construction Engineering

This paper presents the development of indices for assessing user perception of interactive technology elements. An exploratory factor analysis (EFA) was performed using data from Leicht (2009), where teams of engineering students (n=82) were asked to perform a collaborative site planning activity in interactive environments and assessed through a post-activity questionnaire. Two factors, media interaction and team interaction, were identified in the analysis. The two indices for user perception are a 4-item Interactive Media Index (IMI) and 4-item Interactive Team Index (ITI), with Cronbach alphas of 0.80 (IMI) and 0.82 (ITI). The indices provide new assessment metrics to aid researchers in evaluating and researching interactive workspaces. Where previous user perception assessment focused on the usability of a system, these indices provide additional metrics for assessment of technology usage and collaborative usage in tandem. The IMI and ITI are presented and implications are discussed.
