A system and method that allows convenient input of letters, numbers, and characters using an input requiring a minimal number of input buttons or keys enhanced by gestures. The system utilizes a two-stage input, first with an array “call-up” function that allows a user to select a range of letters, numbers, or characters, followed by a subsequent “specification” function that allows a user to select a specific letter, number, or character from the aforementioned array. This allows for input using wearable devices that have minimal surface area, or devices that do not require external keyboards to provide input, such as Blu-Ray players and smart televisions, while also saving space on a display, if utilized on mobile computing devices such as smartphones or tablets. The resulting input can be used in electronic communications such as email and SMS texting, or be used for word processing functions.
