Entering text is an essential task when using a PC or a mobile device (smartphone, tablets, smartwatch, etc.). We enter text when writing documents but also for communicating with others (emails, social networks, messaging…). It is therefore important that text entry is accessible by everyone and on all platforms. Prior work has addressed the problem of accessibility of text input: devices and input techniques adapted for people with motor disabilities, augmentative and alternative communications (AAC) for people with an associated language disorder, and soft keyboards adapted on smartphones people with a visual challenge.
However, despite progress, text input performance (speed and accuracy of text input) remains poor, and accessible text entry often causes fatigue or increased cognitive load. Much remains to be done to improve accessibility for text entry systems.
This Special Thematic Session (STS) solicits recent experiences and contributions on approaches, methods, models, techniques and experimental work for enhancing text entry accessibility for people with disabilities. This Special Thematic Session will consider all aspects of research on text entry, including (but not limited to):

• Measures and models for text entry
• Prediction and completion systems
• Entry devices
• HCI Design
• Evaluation of text entry techniques
• User experience
