SwitchBack: An RF-Based Gesture Input Device


SwitchBack is a novel e-textile input device that can register multiple forms of input (tapping and bidirectional swiping) with minimal calibration. Many existing forms of e-textile input interfaces rely on discrete sensors, requiring an increased number of measurements and computational cost for similar resolution. By using RF, SwitchBack exemplifies enhanced operational benefits – it can work when weatherproofed (limiting susceptibility to the elements), it can register multiple input methods, and it is more robust to accidental triggering. Additionally, the fabric construction allows for integration into numerous textile-based products, offering an increased variety of use cases for a user’s needs.
