AbstractIn computer-mediated tactile intercommunication, users not only have to perceive tactile cues but also have to articulate them to carry a two-way interaction. By pressing buttons or performing specific gestures, interlocutors can exchange tactile signals but are not able to extrapolate the given vocabulary. When more access to hardware parameters is provided instead, interlocutors can have more autonomy. Yet, changes in articulation might produce tactile signals that are not perceptually suitable, hindering mutual understanding during intercommunication. In this paper, we explore the trade-off between freedom of articulation and mutual understanding by comparing three articulatory approaches. Dyads performed a collaborative task using their vibrotactile HMDs to communicate. Their performance during the task, as well as mutual understanding, workload and easiness, were assessed as a function of each articulatory condition. Results show that static and mediating conditions support higher performance and mutual understanding compared to a dynamic articulation. © Springer International Publishing AG, part of Springer Nature 2018.
