This article describes tests that have been conducted with Tactile Dialogues, a textile pillow that can react to touch with vibrotactile stimuli and haptic sensations. Tactile Dialogues is designed to stimulate movement and interpersonal contact for patients in the late stages of dementia, their family members and their caregivers. The most recent prototype of the pillow has been tested during 15 separate visits of family members or caregivers with patients. The aim of these tests is to find out whether personalization of the vibrotactile stimuli is appreciated over a mirroring vibrotactile behavior. We propose a three-scale measurement to help family members and caregivers examine the responses of the patient: muscular relaxation, physical movement and interpersonal contact. Through the semi-structured interviews we identified that family members and caregivers do appreciate the opportunity to personalize the vibrotactile behavior and that the pillow mainly functions as a way to establish communication with the patient.
