The core technology to support this exists today. Samsung’s modular “The Wall” (https://www.samsung.com/us/business/products/displays/direct-view-led/the-wall/
) panels enable a cohesive display across nearly any configuration. Ideally, displays would be installed full floor to ceiling (in reality, starting at the ceiling to as close to the floor as a specific space can make happen could achieve similar results). Ceiling display can use either this technology or a projection technology. All supporting technologies for displaying and/or streaming content already exists.
The modular furniture is one need that will require research and development. Tables that can vary in height (to shift from display to seating) are easy, but more innovative items (ex: modular cubes that can switch from displaying merchandise when open to securing merchandise and becoming seating when closed) will require prototyping and manufacturing.
With regard to milestones, the top priority would be the feature wall opposite of the entrance to the space. Converting this to a ceiling to floor display and pairing with the appropriate audio, video, and internet support would transform the space by itself and enable many instructional and informational activities. (This could be done in today.) The next priority would be the modular furniture and shifting of retail display to enable different event configurations. Finally, the remaining walls and ceiling would follow as the new layout options would fully enable the space.
