A System Transferability Questionnaire (STQ)

Abstract

The usability of a multiple device system largely depends on the ease of which users can transfer between using different devices. This paper is aimed at constructing a System Transferability Questionnaire (STQ) to effectively measure the subjective transferability of a multiple device system. Theoretical rationale and approach to develop the questionnaire were presented. A software usability study was conducted to test the STQ. Results showed that STQ helps to capture four factors regarding transferability, which are transfer experience (TE), overall experience (OE), consistency perception (CP) and functionality perception (FP). Users were more satisfied with OE ( M=5.11 out of 7) and FP ( M=5.20), as compared to TE ( M=4.28) and CP ( M=3.54), indicating redesign is necessary to improve the transferability of the two-software system.
