“…Some of the studies have focused on moving the cursor towards the desired letter of a virtual keyboard by moving the eye in four directions (right, left, up, and down) and the desired letter is selected by the blink of an eye [7,[26][27][28]. The achieved writing speeds are higher than the BCI systems but it is still insufficient when compared with optical tracking based methods.…”

Some disadvantages of optical eye tracking systems have increased the interest to EOG (Electrooculography) based Human Computer Interaction (HCI). However, text entry attempts using EOG have been slower than expected because the eyes should move several times for entering a character. In order to improve the writing speed and accuracy of EOG based text entry, a new method based on the coding of eye movements has been suggested in this study. In addition, a real time EOG based HCI system has developed to implement the method. In our method all characters have been encoded by single saccades in 8 directions and different dwell time. In order to standardize dwell times and facilitate the coding process, computer assisted voice guidance was used. A number of experiments have been conducted to examine the effectiveness of the proposed method and system. At the end of the fifth trials, an experienced user was able to write at average 13.2 wpm (5 letters = 1 word) with 100% accuracy using the developed system. The results of our experiments have shown that text entry with the eye can be done quickly and efficiently with the proposed method and system.

Introduction: Due to the increasing popularization of computers and the internet expansion, Alternative and Augmentative Communication technologies have been employed to restore the ability to communicate of people with aphasia and tetraplegia. Virtual keyboards are one of the most primitive mechanisms for alternatively entering text and play a very important role in accomplishing this task. However, the text entry for this kind of keyboard is much slower than entering information through their physical counterparts. Many techniques and layouts have been proposed to improve the typing performance of virtual keyboards, each one concerning a different issue or solving a specific problem. However, not all of them are suitable to assist seriously people with motor impairment. Methods: In order to develop an assistive virtual keyboard with improved typing performance, we performed a systematic review on scientific databases. Results: We found 250 related papers and 52 of them were selected to compose. After that, we identified eight essentials virtual keyboard features, five methods to optimize data entry performance and five metrics to assess typing performance. Conclusion: Based on this review, we introduce a concept of an assistive, optimized, compact and adaptive virtual keyboard that gathers a set of suitable techniques such as: a new ambiguous keyboard layout, disambiguation algorithms, dynamic scan techniques, static text prediction of letters and words and, finally, the use of phonetic and similarity algorithms to reduce the user's typing error rate.

The developments and improvements in human-computer interaction and information and communication technologies have resulted in innovative assistive technology (AT) solutions for the people with disabilities (PWDs). Although, there have been many new ideas and technologies for assisting the PWDs, still very few of them have considered the workplace environment. Therefore, there is a need to develop a comprehensive universal AT solution that can maximize the PWDs productivity at work. In this work, an AT and smart context-aware solution has been developed to assist the PWDs at the workplace. This has been achieved through the designing and the implementation of a smart unified interface to guide and assist the PWDs. A wireless sensor network has been employed in this context-aware smart solution in order to track and determine user's location. The unified interface is adaptive and includes four modules that are smart helping, smart communication, smart editor, and auto emergency response. A proper AT process and technological design considerations have been adopted to achieve a comprehensive, universal, adaptive, and context-aware solution.
