TIMMi is a textile input device for mobile interactions. It is worn on the index finger to provide a multimodal sensing input metaphor. The prototype is fabricated on a single layer of textile where the conductive silicone rubber is painted and the conductive threads are stitched. The sensing area comprises of three equally spaced dots and a separate wide line. Strain and pressure values are extracted from the line and three dots, respectively via voltage dividers. We demonstrate TIMMi as a finger-worn input device with two applications: controlling music player and interacting with smartglasses.
