abstract = {Gaze-based text entry is undoubtedly one of the most useful applications of eye-tracking technology for human-machine interaction, both in the assistive context (users with severe motor disabilities can exploit such writing modalities to communicate with the world) and as a way to allow touchless text input in everyday life. Different eye-driven text entry methods have been developed to date, and almost all of them require preliminary calibration procedures to work correctly. When a short text, such as a password or a PIN, needs to be entered without using hands or voice, calibration may be perceived as an unnecessary nuisance (and may not be properly maintained in public places due to “ambient noise,” caused, for example, by nearby people). Inadequate calibration may also be a problem in case of assistive uses. In this article we present SPEye, a calibration-free eye-controlled writing technique based on smooth pursuit. Although its writing speed is significantly lower than that of ordinary calibrated methods, the absence of an initial calibration makes it suitable for short text entry. The technique has been tested through several experiments, obtaining good performances in terms of key strokes per character and total error rate metrics, and receiving positive feedback from the participants in the tests.},

abstract = {We present an interface for control of a telerobot that supports field-of-view panning, mode selections and keyboard typing by head- and gaze-interaction. The utility of the interface was tested by 19 able-bodied participants controlling a virtual telerobot from a wheelchair mounted on rollers which measure its wheel rotations, and by 14 able-bodied participants controlling the telerobot with a exercise bike. Both groups tried the interface twice: with head- and with gaze-interaction. Comparing wheelchair and bike locomotion control, the wheelchair simulator was faster and more manoeuvrable. Comparing gaze- and head-interaction, the two input methods were preferred by an equal number of participants. However, participants made more errors typing with gaze than with head. We conclude that virtual reality is a viable way of specifying and testing interfaces for telerobots and an effective probe for eliciting peoples subjective experiences.},

abstract = {Purpose -- The purpose of this paper is to consider the two main existing text input techniques based on ``eye gestures'' -- namely EyeWrite and Eye-S -- and compare them to each other and to the traditional ``virtual keyboard'' approach. Design/methodology/approach -- The study primarily aims to assess user performance at the very beginning of the learning process. However, a partial longitudinal evaluation is also provided. Two kinds of experiments have been implemented involving 14 testers. Findings -- Results show that while the virtual keyboard is faster, EyeWrite and Eye-S are also appreciated and can be viable alternatives (after a proper training period). Practical implications -- Writing methods based on eye gestures deserve special attention, as they require less screen space and need limited tracking precision. This study highlights the fact that gesture-based techniques imply a greater initial effort, and require proper training not only to gain knowledge of eye interaction per se, but also for learning the gesture alphabet. The author thinks that the investigation can drive the designers of gaze-controlled writing techniques based on gestures to put more consideration on the intuitiveness of gestures themselves, as they may greatly influence user performance in the first stages of the learning process. Originality/value -- This is the first study comparing EyeWrite and Eye-S. Moreover, unlike other analyses, the investigation is mainly aimed at assessing user performance with the three text entry methods at the inception of the learning procedure.},
