When you find it challenging to use a traditional keyboard, on-screen keyboards come as the best alternatives. To enhance your writing speed with on-screen keyboards, you can use Dasher, the open-source text-entry system. It is exclusively designed for people with disabilities or those who have limited hand movements so they can do their writing tasks effortlessly. It works with different pointing devices like head or foot mice, touch screens, head trackers, or eye operating technologies.

The exceptional feature of Dasher is its innovative layout, which features a unique display style. In it, you’ll see a letter stream where alphabets flow towards you, and you have to catch one to compose your desired text. Once you select a letter, the interface will zoom it in, and the next matching letter will appear on the screen. This software uses an intelligent prediction engine that automatically learns the frequently used words and displays them.
