Text Input Methods in Virtual Reality using Radial Layouts
Anh Thi Nguyen, Samuel Bittman, Markus Zank · 2020
Currently, the most popular text input method in VR is Controller Pointing (CP). While this method is easy and intuitive to use, it requires users to have steady hands, and the overlaying of the keyboard onto the virtual scene occludes a part of the scene. In this work, we proposed two new text input methods: Sector Input and T9VR , that utilize a circular keyboard that is attached to the HTC Vive controller. A preliminary study with 24 subjects was conducted to explore the potential of the proposed methods, in comparison with CP. While CP performed significantly better than the proposed methods in terms of objective typing speed and error rate, T9VR was able to match with CP in a number of subjective measures.
