HRI MobiSim

A Unity-based mobility simulator that builds interactive traffic scenarios, runs them in the browser, and collects behavioral data.

Scene graph

Every scenario is a plain hierarchy of actors, roads and props. Compose it in the Unity editor, and the same graph drives both the desktop build and the web build.

Data

Trajectories, interactions and events are logged continuously while the simulation runs, then exported for analysis without any extra instrumentation.

Data

Mobility

Cars, scooters, bicycles and pedestrians share one mobility model, so a participant can switch vehicle type without rebuilding the scenario.

Assessments

Surveys and cognitive tasks such as the Stroop test run in context — before, during or after a drive — and their answers stay aligned with the simulation log they belong to.

Assessments — survey
Assessments — cognitive task

Scenario

Real-world maps, traffic rules and scripted events combine into repeatable scenarios you can hand to any participant, anywhere, through a browser.
