This research has addressed the key accessibility issues faced by people with disabilities who need or want to use the mobile phone for voice and data communication. The overall outcomes of the research have established that the benefits and usefulness of the mobile phone are so significant that they should become a necessity for people with a disability. It was demonstrated that, with the proper mechanisms (trials, interfaces etc) and educational programs in place (e.g., workshop), the provision of accessible mobile phones for people with disabilities can significantly improve their quality of life through increased range of accessible activities, and will improve their independence, engagement with their peers, safety, security and self-esteem.
