We present an alternate mobile phone keyboard for inputing text, the JusFone Keyboard. This keyboard allows people to enter characters by resting their finger on a the desired key, and rocking to select a specific character. We ran user tests of the keyboard with 12 seniors comparing it against a touchscreen keyboard, a phone with large buttons, and an on-screen PC keyboard. The users found several things to like about the JusFone Keyboard, including comfort and size of keys and having direct access to characters. Users also had several suggestions about how to make the keyboard better such as making the text on the keys bigger and adjusting the spacing between keys. We also conducted a diary study of a user with reduced hand function who used the JusFone keyboard on his PC. The results indicate that the keyboard may be of assistance to persons with reduced hand function.
