It is a sphere with a radius equal to the depth from the viewpoint to the vanishing point. If visual space is considered to be a unit sphere, the observability of scale at any point is expressed by a differential equation with the deviation angle θ with the line of sight. This visual space model makes it possible to show that the trajectory of a rocket moving in a straight line is an ellipse, and to show changes in cognitive distance (sense of distance) as a probability. Unlike a Riemann sphere, this visual space model is a complex projective space in which a point at infinity (vanishing point) exists in three dimensions.

Technology can make older people anxious. Compared to the development of a physically barrier-free society, the development of a cognitively barrier-free society has lagged behind. We need to improve user interface design not just for older people but for the entire social system. We need to work together across countries to promote the health and longevity of older people.

If the visual space is defined as a three-dimensional complex vector space, perspective is represented as a linear constraint by scale. And the vanishing point with zero scale represents the boundary of the visual space. This indicates that visual space is spherical, which is different from Euclidean space. A new geometric model for visual space allows linear derivation of elliptical orbits. Since it does not involve infinite series, the solution is simple.

When capturing a scene with a camera, objects and points in 3D space are mapped onto a 2D plane, resulting in the loss of depth information. Therefore, depth estimation is essential to reconstruct a scene in a 3D space using only a 2D image. In this research, a 3D complex projective space is assumed as the visual space, and the scale is defined as a measure of the certainty of information in the space, providing a new concept of perspective depth.

Parallel lines never meet in physical space. However, in visual space, they appear to meet at infinity. This suggests that the visual space is a sphere whose radius is the distance to the perspective vanishing point. In this visual cognitive space, when the point of view is the origin, all lines other than straight lines passing through the origin are drawn as curved lines. However, we do not notice that the image of the pillar reflected in the visual cognitive space is a curved line. In the mind, vision transforms the image projected on the spherical surface into a linear image. Taking advantage of this property, an algorithm that converts fisheye images into more normal images with less discomfort was constructed. This is a conversion method for fisheye images that takes advantage of the characteristics of vision.

The images that our vision perceives are slightly different from the entities. Images in visual space are illusions. However, they are indeed based on physical laws. That is optics. A straight line extending from the foot to the left and right and the straight line in front of the eye parallel to it intersect at infinity. This suggests that the straight line in front of the eye is actually curved. This is not a phenomenon unique to the human eye; camera lenses also produce similar images. If the visual space is a sphere like a planetarium and a viewpoint is at the center of the sphere, as shown in the right diagram in Figure 1, then a perpendicular line projected on a spherical surface can be understood to be curved when considered from a three-dimensional perspective. Similarly, the phenomenon of parallel lines intersecting each other is a common phenomenon on a spherical face. From these facts, it can be said that the shape of visual space is a sphere, which has a completely different shape from physical space. We unconsciously learn that the visual space is round every day through our vision. The Herring illusion tells us this.

A physician is a very last person who engages in the treatment of patients with dementia. When they could visit physicians at the pre-onset stage, a variety of treatment options are available. One of the physician-scientists from Kyoto University is now focusing on PHRs related to IADLs to support elder people before they present obvious symptoms of dementia. Her dream is to improve the social side of the quality of life of elder people before they develop dementia. As a part of the medical innovation ecosystem, venture-backed startups play pivotal roles in translational research to clinical research in the US. The SPARK program at Stanford University started to support basic- and physician-scientists to learn and conduct translational research from the academic side. This session also provides topics to discuss CSTI’s ongoing promotion of VC investment in Japan, including tax reform, in order to build a startup ecosystem.

Past Design is one of the components of Future Design proposed by Dr. Tatsuyoshi Saijo and Dr. Yoshinori Nakagawa (Kochi University of Technology). Using the work of ARO (Academic Research Organization) as a subject, the past design as a preparatory phase of Future Design was outlined.

規制要件の壁に阻まれ，日本の医療分野のIT化は米国より10年ほど遅れていると言っても過言ではない．電子カルテシステムも同様で，カルテは院内に保存する事が当時の慣習で，カルテ情報を医療機関外のサーバーに保存することが問題視される時代もあった． ところが東日本大震災の時，岩手医科大学のカルテ情報がネットワーク経由で香川医科大学運営のデータセンターにも保存されており，短時間のデータ復旧が可能であったことから世論が一転し，電子カルテ情報を院外のサーバーに保存することが推奨されるようになった．（SS-MIX） このため従来の紙ベースの法規制を改め，電子データを前提とした新たなガイドライン作りが急務となった．FDA（米国食品医薬品局）では，この課題に世界に先んじて取り組んでおり，FDAからの要請を受け，データ標準化団体のCDISC（Clinical Data Interchange Standards Consortium）が作成していた調査報告書に注目が集まり，DIA（Drug Information Association）日本支部の要請で，その内容を紹介した報告である．
