Watershed Days 2017
Tangibly Smart
An interactive watershed in your hands
Brendan Harmon, Anna Petrasova, Payam Tabrizian, Vaclav Petras, & Helena Mitasova
Tangible Landscape
A tangible user interface powered by open source GIS.
Tanigble interaction with GIS
With Tangible Landscape you can hold a watershed in your hands - feeling the shape of the earth, sculpting its topography, and directing the flow of water.
Why tangible?
- Using your body is natural.
- Using a mouse and keyboard is not natural.
- Collaborating with a mouse and keyboard is really hard.
- Interacting with scientific models is even harder.
How it works
Tangible Landscape couples a digital and a physical model through a continuous cycle of 3D scanning, geospatial computation, and projection.
Realtime 3D scanning
with a Kinect sensor.
