Abstract: A host computer is programmed to receive input specifying definitions of two or more stages, each of the stages representing an attribute of one or more end-user profiles that have undertaken one or more interactions, using computing devices associated with the end-user profiles, with one or more networked computers. For each stage, the user computer can interoperate with a graphical user interface comprising a virtual canvas, a palette comprising a plurality of different graphical icons each representing at least an entry condition and an activation order for digital presentation of information. Visual selection and dragging operations can move copies of an entry condition icon and an activation icon from the palette to the virtual canvas. An entry condition icon is defined using rules to match one or more subsets of the end-user profiles and one or more subsets of the interactions. An activation icon has order attributes order for the digital presentation of information.

Abstract: A mobility support device capable of stably climbing a step without impairing mobility on flat ground is provided. The mobility support device includes a front wheel, a rear wheel, a drive wheel disposed between the front wheel and the rear wheel, a first link coupled to the front wheel, a second link connecting the drive wheel and the rear wheel, a rotation joint coupling the first link and the second link at a first position, and a first elastic member coupling the first link and the second link at a second position different from the first position.

Abstract: It is possible to quickly and efficiently support a user with a limited lower limb motor function in a posture transition with a simplified configuration. A support mechanism that supports a posture transition includes a first link that does not change a posture, a second link that is rotatably coupled to the first link, and an actuator configured to rotate the second link with respect to the first link, in which, when a load on a connection part of the second link and the first link changes due to a change in an upper body posture of a user, based on a relative positional relationship between an ankle joint and a knee joint of the user in a direction orthogonal to a vertical direction in a sagittal plane of the user, the actuator drives the second link while changing a support moment on the user according to a relative positional relationship between the knee joint and an upper body centroid of the user, or a knee joint angle.
