Visual City

An interactive exhibition and lab about Norrköping's urban development, built on a digital twin of the city with AI and computer vision behind it. Unlike the dome or the arenas it is not a single immersive projection system — it is a set of exhibition stations and projected surfaces spread across exhibition levels 2 and 3.

Level 2 — exhibition stations​

Six stations, L2-EXHIB-01-V through L2-EXHIB-06-V, at 172.19.52.11, .21, .31, .41, .51 and .61 respectively.

Temporary addresses

Stations 01–04 also have temporary addresses on the 172.19.53.1x1 range recorded in the source documentation. If a station is unreachable on its 172.19.52.x address, try the temporary one before concluding the machine is down. See Computers, Level 2.

Level 2 also hosts the WATER projectors, which project down onto a table. Their credentials are in Bitwarden, not here — see Projectors, Level 2.

Level 3 — SimStad​

Level 3 runs SimStad on an HP Z workstation with WATCHOUT installed, driving three projectors. It is currently used to show OpenSpace via a DisplayPort frame grabber — i.e. WATCHOUT is capturing OpenSpace's output rather than playing a prepared show. That capture path is worth remembering, because it means a "WATCHOUT problem" here may actually be an OpenSpace problem.

Machines: LVL3-SIMSTAD-01 (172.19.53.41) and LVL3-SIMSTAD-02 (172.19.53.42). See Computers, Level 3 and Projectors, Level 3.

Daily open and close​

Visual City has no operator manual because it runs unattended as an exhibition. The daily routine is:

Opening

  • Walk both levels and confirm every station and projected surface is showing content.
  • Confirm the SimStad projection on Level 3 is running and correctly aligned.
  • Confirm interaction (touch, cameras, sensors) responds.

Closing

  • Return anything left in a menu state to idle content.
  • Note stations that required intervention.
TODO verify with senior technician

Confirm what each Level 2 station displays, whether the temporary IP addresses are still in use, and whether the stations are powered down overnight.
