child with haptic pajama
huggy pajama is a wearable system aimed at promoting physical interaction in remote communication between parent and child. this system, developed by mixed reality lab at the national university of singapore (NUS), enables parents and children to embrace one another through a hugging interface device and a wearable, hug reproducing pajama connected through the internet.
the hugging device is a small, mobile doll with an embedded pressure sensing circuit that is able to accurately sense varying range of human force produced from natural touch. it is connected via the internet to a haptic wearable pajama with embedded air pockets, heating elements and color changing fabric. this pajama is able to simulate hug to the wearer according to the inputs from the hugging interface, as well as generate warmth to accompany the hug, display color changes according to distance of separation between parent and child, and display emoticons. the system provides a semantically meaningful interface that can easily be understood by children and parents as a reproduction of hugging. furthermore, hug sensation is produced in a calm and relaxing way through air, rather than through vibration or other mechanical means.
