• The 9 sensor multi-tap Thumb Keyboard uses a centrally located sensor surrounded by 8 adjacent sensors or eight touch sensor zones, for producing alphabetic characters, a space, numbers, punctuation and symbols using the left or right thumb.
• The 9 sensor Thumb Keyboard can be used on a cell phone menu key, a digital camera menu key, an iPod / MP3 menu key, on a BlackBerry trackball, or on the G1 Android pointing device, making it the world’s smallest data entry keyboard.
• The 9 sensor multi-tap Thumb Keyboard allows a user to text message without ever looking at the input device.
• Activating one of nine sensors:
  1 time produces a 1^st data character,
  2 times produces a 2^nd data character,
  3 times produces a 3^rd data character,
  4 times produces a 4^th data character,
  5 times produces a 5^th data character,
  6 times produces a 6^th data character,
  7 times produces a 7^th data character,
  8 times or more produces additional data characters.
• The 9 sensor multi-tap Thumb Keyboard is faster and more efficient than Tegic's T9 multi-tap method, Motorola's iTAP multi-tap method and ZI Corp's eZiText multi-tap method.
• Many solutions to improve existing problems have been made, but many are not well suited for the blind community, the deaf-blind community and an individual needing to enter data into a device without looking at the keyboard entry device.
• Combining the 9 sensor multi-tap Thumb Keyboard with the PhoneKeyboard.com invention, produces the world's fastest data entry device for 12 key phones.
