Here’s Take Two on our PINQ “Differential Privacy In Action” Demo.
Along with a general paring down of the visual interface, we’ve refined how you interact with the application as well as tried to visualize how PINQ is applying noise to each answer.
- The demo app is no longer modal. Meaning, you don’t have to click a button to switch between zooming in and out of the map, panning around the map and drawing boxes to define query areas. All of this functionality is accessible from the keyboard.
- You no longer draw boxes to define query areas. Instead, clicking “Ask a Question” plops a box on the map that you can move and resize with the mouse.
- Additionally, the corresponding PINQ answers update in real-time as you move and resize the query boxes.
- New thumbnail graphics next to each answer reflect how PINQ generates noisy answers and provide a more immediate sense of the “scale of noise” being applied. (A more detailed explanation of these pointy curves is forthcoming.)
The demo has proven enormously helpful as an aid in explaining our work and our goals. We continue to improve it every time we make use of it, so stay tuned for more to come!
