How Two become One – Creating Synergy Effects by Applying the Joint Interview Method to Design Wearable Technology

Conference paper
Part of the Lecture Notes in Computer Science book series (LNCS, volume 8517)


This paper addresses the design of wearable technology and its user acceptance by applying the Joint Interview Method. In order to further develop a wearable warning system in form of a glove, five semi-structured joint interviews were held by a trained human factors specialist. Each joint interview consisted of one respondent with an engineering background and one respondent with a psychological or cognitive-science background. In this process, the Joint Interview Method revealed two advantages: First, the interviews benefited from the discussion between both participants and, second, it enabled an observation from two different perspectives (i.e. one implementation-oriented view, which focused on the technological capabilities and the other user-oriented view, which focused on human perception and information processing). Both aspects mentioned led to synergy effects. To sum up, the Joint Interview Method turned out to be a promising usability approach to explore new technologies’ potential and user acceptance and therefore, can be recommended for its use in the process of designing and evaluating wearables.
