The Impact of Surface Co-location and Eye-tracking on Mixed Reality Typing
<|reference_start|>The Impact of Surface Co-location and Eye-tracking on Mixed Reality Typing: Accuracy and speed are pivotal when typing. We hypothesized that the lack of tactile feedback on midair mixed reality keyboards may adversely impact performance. Our first experiment assessed the potential to provide tactile feedback to users typing in mixed reality by co-locating the virtual keyboard on a table or a wall. The keyboard was deterministic (without auto-correct), relied only on the headset's egocentric cameras for sensing, and included symbol keys. Users preferred and had the highest entry rate of 12 words-per-minute using a midair keyboard. Error rates were similar in all conditions. Based on user feedback, our second experiment explored ten-finger typing. We used a novel eye-tracking technique to mitigate accidental key presses. The technique halved the number of times backspace was pressed and was preferred by users. However, participants were faster using only their index fingers without eye-tracking at 11 words-per-minute.<|reference_end|>
