Summary of Touché with Arduino
The article discusses Touché, a capacitive-sensing technology developed by Walt Disney Research that enables touch and gesture recognition on various objects using Swept Frequency Capacitive Sensing (SFCS). This technique analyzes the capacitive response over multiple frequencies to detect interactions. A DIY Arduino-based project inspired by Touché is in early development, with ongoing improvements planned. Additional resources and a step-by-step instructable are available for those interested in replicating the technology.
Parts used in the Touché Arduino Emulation Project:
- Arduino microcontroller
- Capacitive sensing electrodes
- Frequency sweeping circuit components (resistors, capacitors)
- Connecting wires
- Breadboard or PCB
- Power supply (e.g., USB or battery)
Touché is a capacitive-sensing technology, developed by Walt Disney Research, which aims at providing touch and gesture sensitivity to a great variety of objects. From this research paper:
The technique behind Touché is known as Swept Frequency Capacitive Sensing (SFCS): at a glance, by monitoring the capacitive response of an object over a specific range of frequencies (instead of a single one), it is possible to infer about its interaction with the outside world.
In his blog, Dzl describes his personal approach toward the development of a system capable to emulate Touché’s behavior with Arduino. Currently, the project is still in a early stage, but improvements and further developments are expected soon.
