In our current research, we assessed the feasibility of integrating a dual coded robot's feedback. Dual coded feedback consists of the robot combining it visible behaviors (e.g.: the robot's movement) with auditory icons which we refer to as Inarticulate Utterances (IUs). In our study, we investigate whether using dual coded robot's feedback during the Human-Robot Interaction (HRI) may help maintaining the rules of interaction (protocol) that are previously established in an adaptive way

We compare dual coded feedback with other alternatives which are baseline condition in which only the robot's visible behavior is the only afforded feedback for the human and another manipulation condition that consists on changing the IUs version during the second HRI instance when the human is supposed to remember the Previously Established Communication Protocol (PECP). As expected, using dual coded feedback afforded better interaction outcomes in terms of protocol remembrance and subjective evaluation of the HRI in comparison to the baseline and manipulation conditions.  Index Terms-Inarticulate utterance, protocol of communication, dual-coding, recall 1 A minimal designed robot has small number of sensors and simplified in terms of anthropomorphic features. The design of the robot should be efficient enough to make the minimalistic robot sociable but also affordable (cost) for common non-expert users. 2 Social face: It is the individual's portrayed identity in a particular situation. It is highly related to self-esteem.
