Further, the two best performing keyboard layouts have been evaluated with eye-tracking alone on ten stroke patients. Five different keyboard layouts have been presented and evaluated with ten healthy participants. The system can be controlled in two different modes: eye-tracking alone and eye-tracking with an access soft-switch. The optimized graphical user interface (GUI) layout has been designed for a Hindi language virtual keyboard based on a menu wherein 10 commands provide access to type 88 different characters along with additional text editing commands. In this work, we propose a novel method for optimizing the position of the displayed items for gaze-controlled tree-based menu selection systems by considering a combination of letter frequency and command selection time. To date, virtual keyboard optimization schemes based on script-specific information along with multimodal input access facility are limited. Virtual keyboard applications and alternative communication devices provide new means of communication to assist disabled people. Using a linear support-vector machine, we achieve an overall accuracy over 88% for the article-genre detection by using a leave-one-subject-out cross-validation evaluation.

The statistics-based features focus on modeling the overall gaze-typing behaviors during the process and the sequence-based features focus on the transition of the gaze-typing behaviors as the piece of writing progresses. Our method deploys statistics- and sequence-based features to infer the mental state of the author during the writing process. Our study involves 46 native Chinese speakers of varying ages from children to elderly. Our study focuses on Chinese typing, particularly via the Pinyin input method, which generates text via a two step method, and requires additional cognitive processes compared to typing in phonographic languages such as English. In this paper, we study the gaze-typing behaviors, specifically, the coordination between eye gaze and typing dynamics, of writers who are producing original articles in different genres: reminiscent, logical and creative. However, only a few studies have explored this relationship. Given that writing is an intensively cognitive process, it makes sense that the type of writing that is being produced would have an effect on the writer’s gaze and typing behaviors. Writing is one of the most common activities undertaken on a computer, and the activity of writing has been widely studied.
