Adaptive, Multimodal, Application Independent User Interfaces For People With Disabilites Using Computers

The goal of this thesis is to create more adaptive and flexible user interfaces for people with disabilities and presenting information to everyone and on every device at any time. Delivering information at any time leads to situations such as a person walking with a mobile device having a small screen wanting to make a flight reservation. The intention of presenting information to everybody immediately raises the question of how much of the available information reach people with disabilities. We have suggested a content based user interface language that may be used by external services to interact with the user. The user interface component delivers information adapting to the user's preferences, device characteristics, and also by adopting multimodality principles. As a proof of concept, we have implemented the reminder service to deliver reminder messages to people with different disabilities and we have collected data on users' experience.
