Jiajing Guo, Andrew Benton, Nan Tian, William Ma, Nicholas Feffer, Zhengyu Zhou, Liu Ren · 2023
Efficient text entry is a crucial aspect of the user experience for augmented reality (AR) head-mounted displays (HMD). Eye-tracking for virtual keyboard interaction is a popular choice for AR text entry, as it is intuitive, privacy-preserving, and socially acceptable. However, as AR HMDs move toward more consumer-friendly form factors and price points, technical constraints necessitate trade-offs that result in a limited field of view (FoV) and reduced eye-tracking accuracy.
