Method for a chord input of textual, symbolic or numerical information
First Claim
1. A machine for entering symbols comprising of:
- a. a set of input zones for user to put his hands on with means for assigning a set number of input zones for each of the set number of fingers of each hand, andb. input zones designed with means for reacting to user'"'"'s finger action, andc. input zones designed to allow the fingers to remain in determined positions without the need to search for the input zones they need to touch for each entry of a symbol, andd. a set of pre-defined patterns of activated zones, with means for establishing a correspondence between each combination and a single certain symbol, whereas there are possible assignments for each of all used symbols to a certain pattern, ande. said set of pre-defined patterns of activated input zones, with means for utilizing a set number of fingers of each hand for entering each of all used symbols, andf. said set of pre-defined patterns of activated zones, with means for utilizing the lowest finger of the set fingers exclusively for the functionality features of symbol input, such as shift, caps, shift-lock, caps-lock, backspace, delete, enter, case, menu access and for other similar functions, andg. a system with means for comparing a collected pattern of activated zones with a pre-defined set of patterns, to determine the symbol that was entered, whereby said machine will allow the desired symbol to be entered, as a reaction to activation of certain zones by using a definite number of fingers to provide user with the possibility to enter all necessary symbols without switching between sets or cases, and to use the additional third finger to invoke all the remaining functional features of manipulating the device.

Abstract
A system and method for chord input of symbols, by up to three fingers of each hand. The system consists of twelve input zones (2), two for each finger, positioned to match the grip of the hand. For one of the proposed embodiments, a handheld device (3), input zones are on device'"'"'s back (1) in order to face the fingers of the holding hand. Entry is achieved by simultaneous activation of the zones by the fingers (“chord” or “pattern”), decoded by a translation patterns'"'"' table, to a desired symbol. Invention permits the fingers to reside at predetermined positions and move only along one axis, eliminating a need to find a spot for placing a finger, and minimizing the time required to make decisions on where to move. And since only two fingers of each hand are required for most of the symbols, method is a fast, effective and error-prone.

8. A method of entering symbols comprising of the following steps:
-
a. providing a set of zones for user to put his hands on, with means for assigning a set number of zones for each of the set number of fingers of each hand, and b. providing the zones with means for reacting to user'"'"'s finger action, and c. placing the zones with means to allow the fingers to remain in determined positions without the need to search for the input zones they need to touch for each entry of a symbol, and d. providing the set of pre-defined patterns of activated zones, with means for establishing a correspondence between each combination and a single certain symbol, whereas there are possible assignments for each of all used symbols to a certain pattern, and e. providing such set of pre-defined patterns of activated zones, with means for utilizing a set number of fingers of each hand for entering each of all used symbols, and f. providing such set of pre-defined patterns of activated zones, with means for utilizing the lowest finger of the set fingers exclusively for the functionality features of symbol input, such as shift, caps, shift-lock, caps-lock, backspace, delete, enter, case, menu access and for other similar functions, and g. providing the system with means for comparing a collected pattern of activated zones with the pre-defined set of patterns, to determine the symbol that was entered, whereby said method will allow the desired symbol to be entered, as a reaction to activation of certain zones, by using a definite number of fingers to provide user with the possibility to enter all necessary symbols without switching between sets or cases, and to use the additional third finger to invoke all the remaining functionality of manipulating the device.
