Virtual Dynamic Keyboard for Communication in Intensive Care

Abstract

Effective communication is of great importance for intensive care patients in the weaning process to express their needs adequately. To support this process, the ACTIVATE patient application was developed, providing a selection of typically used texts via a novel interaction device BIRDY, intended to be used in bed. However, there are situations where patients would like to express more. Since the traditional layout of a static keyboard does not fit well with BIRDY gestures, we developed a virtual dynamic keyboard with letter prediction and minimal input gesture needs. We tested different text corpora and forecasting models, implemented a prototype based on the best candidate, and performed a preliminary user evaluation. The new virtual dynamic keyboard is shown to be superior compared to static layouts.
