Abstract

Efficient text entry is essential to any computing system. However, text entry methods in virtual reality (VR) currently lack the predictive aid and physical feedback that allows users to type efficiently. The state of the art methods such as using physical keyboards with tracked hand avatars require a complex setup which might not be accessible to the majority of VR users. In this paper, we propose two novel ways to enter text in VR: 1) Word-gesture typing using six degrees of freedom (6DOF) VR controllers; and 2) word-gesture typing using pressure-sensitive touchscreen devices. Our early stage pilot experiment shows that users were able to type at 16.4 WPM and 9.6 WPM on the two techniques respectively without any training, while an expert's typing speeds reached up to 34.2 WPM and 22.4 WPM. Users subjectively preferred the VR controller method over the touchscreen one in terms of usability and task load. We conclude that both techniques are practical and deserve further study.
