SCALE provides a framework for load data from distributed load-sensitive modules for exploring force-based interaction. Force conveys not only the force vector itself but also rich information about activities, including way of touching, ob- ject location and body motion. Our system captures these interactions on a single pipeline of load data processing. Fur- thermore, we have expanded the interaction area from a flat 2D surface to 3D volume by building a mathematical framework, which enables us to capture the vertical height of a touch point. These technical invention opens broad applications, including general shape capturing and motion recognition. We have packaged the framework into a physical prototyping kit, and conducted a workshop with product designers to evaluate our system in practical scenarios.
