Abstract: The systems and techniques described herein implement an improved gaze-based on-screen keyboard that provide dynamically variable dwell times to increase throughput and reduce errors. Utilizing a language model, the probability that each key of the on-screen keyboard will be the subsequential key can be determined, and based at least in part on this determined probability, a dwell time can be assigned to each key. When used as an iterative process, a minimum dwell time may be gradually reduced as confidence in the subsequential key increases to provide a cascading minimum dwell time.
