PrintSense: A Versatile Sensing Technique to Support Flexible Surface Interaction


Touch sensing has become established for a range of devices and systems both commercially and in academia. In particular, multi-touch scenarios based on flexible sensing substrates are popular for products and research projects. We leverage recent developments in single-layer, off-the-shelf, inkjet-printed conductors on flexible substrates as a practical way to prototype the necessary electrode patterns, and combine this with our custom-designed PrintSense hardware module which uses the full range of sensing techniques. Not only do we support touch detection, but in many scenarios also pressure, flexing, and close proximity gestures.
