Head-Based Text Entry Methods for Motor-Impaired People

Abstract

This article describes methods for text input using head mounted devices. The efficiency of six different virtual keyboards in a 3D environment were evaluated during experiments. Some of used techniques were already known earlier (dwell time, multimodality, swipes), while others are new (control of virtual cursor arrows, 8-button layout, half-star layout). Although the obtained results are not groundbreaking, the obtained results allow a good prognosis for head-based methods using VR goggles.
