A person's emotions and state of mind are apparent in their face and eyes. As a Latin
proverb states:'The face is the portrait of the mind; the eyes, its informers'. This presents a …

Users of augmentative and alternative communication (AAC) devices sometimes find it
difficult to communicate in real time with others due to the time it takes to compose …

Despite the increasing popularity of head mounted displays (HMDs), development of
efficient text entry methods on these devices has remained under explored. In this paper, we …

In topography-based verbal behavior, different antecedent stimuli control different
topographies of responding, whereas in selection-based verbal behavior, different …

We present cascading dwell gaze typing, a novel approach to dwell-based eye typing that
dynamically adjusts the dwell time of keys in an on-screen keyboard based on the likelihood …

Text entry is a common activity in virtual reality (VR) systems. There is a limited number of
available hands-free techniques, which allow users to carry out text entry when users' hands …

With eye-tracking increasingly available in Augmented Reality, we explore how gaze can be
used to assist freehand gestural text entry. Here the eyes are often coordinated with manual …

Text entry using gaze-based interaction is a vital communication tool for people with motor
impairments. Most solutions require the user to fixate on a key for a given dwell time to select …

Current eye-tracking input systems for people with ALS or other motor impairments are
expensive, not robust under sunlight, and require frequent re-calibration and substantial …

Motivated by the need for accelerating text entry in augmentative and alternative
communication (AAC) for people with severe motor impairments, we propose a paradigm in …
