These results show that the proposed keypad and dialer has a gentle learning curve and results in minimum typing errors thus reducing cognitive load on the blind user. First, give your keypad membrane a cleanup if you stuck with option 1 of fixing it so its nice and shiny. Pads mostly containing numbers and used with computers are numeric keypads. The results were then compared with the existing ordinary and QWERTY keypads. A keypad is a block or pad of buttons set with an arrangement of digits, symbols, or alphabetical letters. The responses were then tested and analyzed using standard statistical tests. Their experiences were then recorded using interviews and observation. They were initially trained on using the proposed keypad. The proposed keypad was tested on selected groups of blind users from both the countries where the research was performed. Based on our prior study on screen division layouts, this paper proposes and evaluates a dialer and keyboard for blind users of a smartphone. This necessitates the need for customizing the current keypad and dialer to enable a blind user to perform common activities of making a call, sending and receiving SMS messages and e-mails and browsing internet without visual feedback. The existing keypad layouts make it difficult for the users to easily operate a touch screen device even for entry-level activities. Blind users face a number of challenges in performing common operations of text-entry, text selection, and text manipulation on smartphones.
