Abstract: This interaction system comprising a display assembly associated with an avionic screen and including a video acquisition module configured to acquire a first graphic feed coming from an avionic system and a second graphic feed coming from an open-world equipment item, a media management module configured to control the display on the avionic screen and to generate windowing data relative to the positioning of different windows on the display screen and an interaction assembly able to generate interaction data. The system further comprises a connection box of the open-world equipment item and a control module of the open-world equipment item configured to process the windowing data and the interaction data in order to generate, from at least some of the interaction data, a command intended for the open-world equipment item.

Abstract: The orthotic is formed of a monolithic semi-rigid resilient shell for engagement inside a footwear and for conformingly fitting against the plantar portion of a patient's foot. The orthotic includes a rear heel cup portion that may have inner and outer rearwardly-extending resiliently deformable arms defining at their rear ends a rearwardly-opened notch therebetween. A number of first grooves may be made along the outer or inner flange of the heel cup portion, on the exposed top or bottom surface thereof. The orthotic further comprises a front end portion for engaging the metatarsal plantar region of the foot, having a sinuous front edge which includes five frontwardly-facing arcuate concavities each for registering wedging engagement therein by a corresponding one of the five metatarsal anterior portions of that person's foot.
