Abstract:
A keyboard arrangement comprising:a plurality of manually actuable keying means in a fixed array, each keying means being capable of being placed into any of three or more states by slight movement of a single finger of a typist, and at least some of said states are selected electronically or by software selection means to correspond to symbols such as letters, numbers, punctuations and special characters in a given language; wherein information corresponding to said symbols is to be conveyed to information receiving means associated with the keyboard arrangement, and wherein at least some of the symbols that correspond to the keying means are assigned to at least one of a plurality of attribute classes according to the number, position, direction or contours of the lines within the symbols such that either (A) there are at least five keying means, each keying means corresponds to at least three symbols within the same attribute class, and wherein the attribute classes include a first class of symbols having a top right oblique line and exemplified by K, k, W, w, X, x, V, v, Z, z, /, %; a second class of symbols having a centrally-disposed, horizontal line and exemplified by A, E, F, H, +; a third class of symbols having a straight line intersected by a straight line extending leftwardly and exemplified by X, x, Z, z, y, T, t, A, H, 4, #, +; a fourth class of symbols having a left convex curve and exemplified by C, c, G, O, o, a, d, e, q, g, S, s, 6, 0, (, @, &; a fifth class of symbols having a partial or complete loop and exemplified by U, u, C, c, G, Q, o, O, @, %; a sixth class of symbols having a double curve and exemplified by S, s, B, m, g, 3, 8, $, &, {tilde over ( )}; a seventh class of symbols having a right convex curve and exemplified by B, b, D, P, p, R, S, s, O, o, 0, 2, 3, 9, 5, ); an eighth class of symbols having a horizontal line and an intersecting, downward extending line, exemplified by T, t, Z, z, E, 4, 7, F, +, #; a ninth class of symbols having a single vertical line and exemplified by L, l, I, J, j, T, t, P, p, D, d, E, F, f, K, k, B, b, q, l, !, Â¦; and a tenth class of symbols having a top left oblique line and exemplified by K, k, W, w, M, N, V, x, ; a eleventh class of symbols having a straight vertical line with a line projecting at a right angle and exemplified by E, F, H, T, f, t, +; a twelfth class of symbols having a curve open at the bottom and exemplified by h, m, n; a thirteenth class of symbols having lines converging superiorly and exemplified by K, k, W, w, X, x, M, N, A, {circumflex over ( )}; a fourteenth class of symbols having lines converging inferiorly and exemplified by K, k, V, v, W, w, X, x, Y, y, M, N; a fifteenth class of symbols having lines converging to the left and exemplified by K, k, X, x, Z, z, 7, >; a seventeenth class of symbols having two, vertically-separated, horizontal lines and exemplified by Z, z, E, F, =, #; an eighteenth class of symbols having two, horizontally-separated, vertical lines and exemplified by H, h, M, m, N, n, U, u, #; a nineteenth class of symbols having a line and a closed loop at one end of said line, and exemplified by b, d, P, p, q, R, 6, 9; a twentieth class of symbols having a closed loop on the top and exemplified by P, p, q, B, R, 9, 8, %, &; a twenty-first class of symbols having a closed loop on the bottom and exemplified by B, b, d, 6, 8, %, &; a twenty-second class of symbols having a closed loop on the left and exemplified by d, g, G, q, %, &; a twenty-third class of symbols having a closed loop on the right and exemplified by B, b, P, R, 6, %; a twenty-fourth class of symbols having a curved line constituting an incomplete loop and exemplified by C, c, G, j, m, n, U, u, 2, 3, 5, ?, (,) a twenty-fifth class of symbols having a line that projects below the line of writing and exemplified by j, p, q, y; a twenty-sixth class of symbols having a straight horizontal line exemplified by e, E, f, F, t, T, z, Z, 2, 4, 5, 7, âˆ’, _, A, F, H, L, #, B; or (B) there are a curved class of symbols, each of said symbols having a curved line, and a noncurved class of symbols, each of said symbols lacking a curved line, such that each there are at least four keying means that correspond to either an upper or lower case form of a letter symbol in the curved class and at least one other keying means that corresponds to an upper or lower case form of a letter symbol that is assigned to the curved class, and there are at least five keying means that corresponds to either an upper or lower case form of a letter symbol in the noncurved class and at least one other keying means that corresponds to an upper or lower case form of a letter symbol that is assigned to the noncurved class;
