In this work, we propose RotateEntry, a controller-rolling-style method for text entry on three degrees of freedom virtual reality devices. To move the key-selecting cursor in two dimensions on a QWERTY layout virtual keyboard, we developed three variants of RotateEntry: Rotate Column Rotate, Rotate Key, and Rotate Column Point. We conducted a comparative empirical evaluation of the four text input methods, including three proposed controller-rolling-style text input methods and the standard raycasting-style one. Text entry performance, accuracy, workload, usability, and user experience were tested and evaluated. Due to the COVID-19 situation, our study was conducted remotely. The impact of using online formats on VR research had also been assessed. After evaluating with 5 participants, we identified that Rotate Key had a higher text entry rate, outstanding overall user experience, and excellent overall workload performance among the three variants of RotateEntry. However, no evidence had been investigated to support the hypothesis that RotateEntry had better performance and experience compared to Raycasting.
