Suggested topic: Measuring Trust

Trust is an essential pre-requisite and quality of human-computer interaction (HCI), involved in a variety of domains including banking, commerce, communication, identification and authentication, and many more. Despite the importance of trust in HCI, we found existing trust scales to be difficult to use in practical HCI research: they consist of lengthy questionnaires that take a long time to fill and place a significant burden on respondents. Shorter scales or alternative measuring methods are needed.

For this suggested research topic, we suggest that students may investigate the state-of-the-art in the measurement of trust, including the pros and cons of existing trust scales, with regard to practical application in HCI research. Methodologically, this can be achieved by conducting a systematic literature review. The review should follow guidelines such as the PRISMA workflow [1]. For this topic, a primarily qualitative review is likely most suited, but quantitative analysis may also be included to some extent.

Workflow for conducting a systematic literature analysis. Methodologically, a systematic literature review should carefully plan and document the identification, screening, and eligibility decisions made while searching and reading literature, as well as how eligible papers were analyzed and how conclusions were drawn. Figure based on the PRISMA workflow diagram [1].

As a benefit for students interested in this topic, the suggested research provides an opportunity for learning and practicing systematic review methods – an essential skill for describing the state-of-the-art in any scientific undertaking.
