MIT’s KnittedKeyboard II just isn’t practical enough to use everyday, and TypeAnywhere, developed by researchers at the University of Washington, is the complete opposite. Put simply, the system consists of sensors you wear on each finger capable of detecting tap-actions on nearly any surface. A decoder then converts these tap sequences into text on-screen.
TypeAnywhere was actually developed around the Tap Strap1 wearable keyboard, one that uses accelerometers to detect tap-actions. These tap-actions are sent to a neural decoder modified from the BERT model that then displays the output text on a typing interface. The researchers also designed a text correction interaction, thus negating the need for cursor navigation.

Our results demonstrate that users can quickly learn TypeAnywhere with minimal practice and achieve high performance after practicing for a total of 2.5 hours. As a result, we think TypeAnywhere has potential as a text entry solution for ubiquitous computing environments,” said the researchers.
