Abstract:
1. A hand-writing device for inputting characters, comprising: an input surface; a guidance device provided on said input surface and extending along a predetermined track for guiding hand-writing strokes to follow said predetermined track, said predetermined track including a plurality of stroke segments arranged for receiving hand-writing strokes to generate said input characters, wherein said plurality of stroke segments include a plurality of horizontal stroke segments, a plurality of vertical stroke segments, and a plurality of diagonal stroke segments, wherein said guidance device further includes a closed edge surface formed about an entire outer perimeter of said predetermined track, and wherein said guidance device further includes a plurality of interior projections spaced inward from said closed edge surface for guiding said hand-writing strokes to follow said predetermined track, wherein said closed edge surface and said plurality of interior projections identify an absolute position of said hand-writing strokes within said predetermined track; and a plurality of switch elements provided at positions on said predetermined track, wherein each stroke segment includes at least one respective switch element, wherein at least a certain of said switch elements being triggered by a hand-writing stroke to produce an output signal when a specific character is input by hand-writing, and wherein the combination of the output signals of said triggered switch elements correspond to the inputted character.
