HYPERSPECTIVE: New Perspectives Formed by Egocentric Interactions

for Minding the Embodied and Cognitive Gaps in the fields of Rehabilitation, Education, and Design


In the field of rehabilitation, it is important to share kinesthetic information, such as muscle activity which is hardly observed by visual sensation, between a physical therapist and a patient. For product designers and nursing teachers, it would be valuable embodied experience to see and explorer classrooms or hospital space from a child's lower stature. We never know how Parkinson's patients manage eating utensils with hand tremors. These embodied experiences are usually difficult to be fully transferred to or reproduced on an another person through conversations or visual materials.


In order to assist in understanding one’s physical and cognitive characteristics in an embodied manner, we aim to establish an environment in our body in which a leaner can acquire one’s embodied knowledge based on the learner’s egocentric embodied interactions in a real space, rather than presenting one’s embodied informations on a computer screen. To achieve this concept, I have developed several wearable devices such as:
1) a wearable Augmented Reality device which provides a child’s visual perspective by modifying the wearer’s height of line of sight;
2) a pair of hand exoskeletons which provides a child’s haptic perspective by scaling down the wearer’s hand dimension;
3) a pair of wearable stimulation devices which provides a patient’s kinesthetic perspective by sharing muscle activity, such as Parkinson's tremor, among people.


These devices allow the wearers to acquire one’s embodied knowledge from their subjective and egocentric experiences since these modifies their perceptions of body. I defined such new embodied perspectives toward other people formed by this phenomena as HYPERSPECTIVE (hyper + perspective). I explore hyperspective technologies for assisting mutual understanding among people in the fields of rehabilitation, education, and design process, and would like to contribute to the establishment of an infrastructure for realizing a society, in which all people, with or without disabilities, can maximize their own ability and support each other.

HYPERSPECTIVE: 自己主体的なインタラクションに基づく新たな視点の獲得

for Minding the Embodied and Cognitive Gaps in the fields of Rehabilitation, Education, and Design




1) 自分の頭部の位置を変えることで小児の視覚的視点を得られる装着型デバイスや,
2) 自身の手を縮小することで小児の"力覚的視点"を再現する手指外骨格,
3) さらに患者と自身の筋活動を共有することで患者の"運動覚的視点"を得られる筋活動共有デバイス


HYPERSPECTIVE (hyper + perspective,超主体視点)と定義し,この視点の提供を通して人々の間の自発的な身体知の獲得を促進し,リハビリテーションや教育,デザインにおける相互理解の深化を支援します.このような超主体視点技術の研究開発を通して,年齢・性別・言語・障害の有無などの格差なく,個々人がそれぞれの能力を最大限に発揮できる社会の構築を人間情報学の側面から支援します.
