We have been developing a set of wearable devices for providing an egocentric child experience to the wearer, named CHILDHOOD. The system is composed of two wearable devices: 1) a visual translator for mapping the wearer's eyesight level onto his/her waist position by using a head-mounted display and a wearable camera module, and 2) a pair of passive hand exoskeletons for miniaturizing hand gestures by using motion conversion mechanisms. In this paper, we revised the configuration of the visual translator to improve the usability, and implemented a new passive mechanism of the hand exoskeleton for achieving natural grabbing motion. We conducted a field study at a nursing school for evaluating how the visual system modulates the perception of interpersonal distance, and also performed a lab study to observe the changes in a user's hand function while using the exoskeleton with a peg test environment.

By leveraging the large-scale interactive floor projection system installed in a special-needs school gymnasium (FUTUREGYM), we aim to support youths with special needs in the acquisition of proper working procedures when cleaning the floor. The trajectory of a mop can be visualized by floor projection after or during the cleaning session. In order to manipulate tools for cleaning, the ability of spatial perception and coordinated movement is necessary, which is sometimes difficult for people with Neurodevelopmental disorders (ND). Here, we verified three different kinds of floor projection methods to give feedback of the trajectory of the mop, which is generated according to the position of both the person and the mop.
