Abstract
Robot therapy for the elderly had been a novel advent for the past decade and the efficacy of such therapeutic procedures had similar benefits to pets in improving health outcomes. But there had been experiments which resulted in showing the loss of interest over time due to limited levels of interaction. This paper regards that if a collection of customizable interactive games comes along with the robotic pet dog, the long-term interest will sustain and in effect, long-term psychological benefits would be rendered. Here in this study, we investigate the effect of elderly interacting with pet robot thought multimodal peripheral devices with a different level of cognitive challenges using questionnaire, facial temperature, EMG and EEG.
