Abstract—This paper presents a new text entry method, Feature Stroke (FS). FS is a predictive letter-group-based method using joysticks. 26 letters are grouped and associated with 8 primitive gestures on joysticks. FS has a novel mnemonic strategy for visual feedback of uncertainty in the group-based inputting. The design of FS is aimed to improve efficiency and user experience of text entry in some special circumstances using joysticks. Multi-session test of the prototype shows that the learning curve rises quickly. And the participants’ subjective evaluation is highly positive. In the non-predictive mode, pairwise test shows that skilled users’ performance of FS is much better than that of the onscreen keyboard selection, the most prevalent method for joysticks so far.
