Wearable haptic device to present contact sensation based on cutaneous sensation using thin wire

In this paper, we propose a fingertip-mounted type haptic device to present haptic feedback for mixed reality environments with mobile devices. Our research goal is the realization of a device that causes no discomfort to the users and is virtually felt even during equipment. To achieve this, we realized a fingertip-mounted type device to present contact sensation to cutaneous sensation using thin wire to fulfill three required technical specifications; the weight must be lightweight (1.4g), has to have a fast response, and should have few obstacles on the fingertip abdomen. Our device can present virtual objects to users. Moreover, since a response of an actuator also improves, quality force sense presentation is achieved. And the device can overlay the sense of force without barring ordinary manipulation of real objects or other users. We believe that our work enables new entertainment expansion such as users will be able to touch CG character directly using their fingers.
