Project Mihr: Enabling Gestural Interactions on a Keyboard using a Graphene-based Fabric
Yiyue Luo, Evelina Barhudarian, Teddy Seyed · 2023
The physical keyboard has long been the de facto input mechanism for computers, despite advances in other input forms and modalities. Even with these advances, the augmentations of physical keyboards have still been limited to keystroke-based entry. We leverage the inevitable physical touch and motions over a keyboard during keystroke-based input to present Project Mihr, a physical keyboard that has been augmented to be touch-sensitive. We leveraged passive capacitive sensing with a graphene-based textile to detect and classify rich and expressive gestural interactions over a keyboard. We conclude this work by describing our characterization on the sensing performance and presenting several different application scenarios that are enabled by our technique over keyboards.
